The Glycemic Index and Dieting

The field of nutrition is awash with charts, tables, diagrams, models, acronyms, and abbreviations; more than the average person can memorize. As such, one often comes across someone who has simply burnt out trying to keep track of how much to eat, when to eat it, how to find the calories from fat, the RDI, the DV, and so on. There is an overkill of useful information within the nutrition field, and it can ironically provoke one to grow weary and exhausted, tune out, and go grab a fast food burger.

Yet every once in a while, a concept within the nutrition field emerges that truly demands attention. Over a decade ago, the USDA’s “Food Pyramid” was one such concept because it helped eaters discover how many gaps existed in their typical daily diet. Now, as the Food Pyramid begins to take a new shape, and as the nutrition field works to establishes itself as the most important branch of health care in the 21st century, an invention called the Glycemic Index is taking center stage.

The Glycemic Index (GI) is not new; it has been around for more than 2 decades. Yet until recently, its exposure beyond the world of diabetes has been limited [i].

The Glycemic Index indicates how “high” or “low” blood sugar levels change in response to carbohydrate intake. A “high” Glycemic Index indicates carbohydrates with a swift breakdown, whereas a “low” Glycemic Index indicates carbohydrates with slow, gradual breakdown. Both terms are of equal importance to diabetics, because there are times with high Glycemic Index foods are required, and times where low Glycemic Index foods are required.

Indeed, the Glycemic Index itself is not new, but its application far beyond the borders of a diabetic dialogue is notable; especially for dieters.

People striving to lose weight often face a nemesis much tougher than establishing an exercise regimen or introducing healthier foods into their diet. The problem is one of energy. Many dieters are surprised – and disturbed – to learn that their diet program is causing them to lose more than inches and pounds: they are losing energy.

This is often expressed as a complaint, as in “I’m feeling weak”, or even “I can’t stay awake”. Many dieters and those advising them have erroneously chalked this up to a matter of attitude, or will power, or some non-biological cause.

The plain truth is that many dieters have been oblivious to the Glycemic Index, and hence, to the fact that many of the diet foods they have eaten – or are eating right now – score very high Glycemic Index levels. As such, these foods are providing a quick boost to blood sugar levels, and then setting up the dieter for the inevitable fall. This is because high GI foods typically increase blood sugar values, which in turn trigger the hormone insulin to clear sugar from the blood. Since blood sugar (a.k.a. glucose) largely dictates the body’s energy levels, it stands to reason that this process manifests as an initial boost in energy, and then as a depletion of energy. This rise and fall of blood sugar – and energy – is often described by dieters using a “roller-coaster” analogy: one minute they feel confident and strong, and the next, they are about to pass out and require some kind of stimulant in order to make it through the day.

Regrettably for many dieters, that stimulant is usually more high Glycemic Index foods, such as sugary snacks or soft drinks. It is easy to see how this experience can lead an individual to stop dieting. After all, before the diet, the individual was merely gaining weight. On the diet, the individual is gaining weight and is exhausted for most of the day. It is better to quit the diet.

The above scenario only takes place, however, when a dieter unwittingly eats high Glycemic Index foods. Research has shown that low Glycemic Index foods, which raise blood sugar levels much more gradually than high Glycemic Index foods, are very helpful for dieters [ii]. This is because a dieter will experience less of a “roller-coaster” ride while on the diet, and furthermore, will be less inclined to snack because energy in the form of blood glucose is being released slowly and gradually. Low Glycemic Index foods are much more efficient sources of energy than high Glycemic Index foods, because the body needs less insulin to convert food into energy [iii].

Despite the growing awareness that low Glycemic Index foods are beneficial, the world of diet foods has not kept pace. This is because many manufacturers are searching frantically to find low Glycemic Index carbohydrates sources for their products, and overlooking a basic, simple fact: the lowest possibly Glycemic Index is no carbohydrates at all.

These zero-carbohydrate/zero sugar nutritional supplements – which are quite rare in the market – do not deliver any sugar to the bloodstream. As a result, dieters do not have to worry about riding the “roller coaster” of energy spikes and pitfalls.

Yet there is an even greater benefit for dieters who choose a ‘zero sugar’ nutritional supplement. If that low Glycemic Index nutritional supplement is rich in complete protein, then it will act as a sort of antidote to high GI foods by helping to combat their adverse consequences.

For example, a dieter who eats a high Glycemic Index candy car can mitigate the roller-coaster spike in blood sugar levels by eating a nutritional supplement that has very low Glycemic Index and has a rich source of complete protein. This is because the protein in the nutritional supplement mixes with the high Glycemic Index of the candy bar, and effectively lowers the overall Glycemic Index. This is welcome news to dieters who would otherwise be seeing those extra carbohydrates transformed by insulin into triglycerides, and stored in adipose tissue; also known as body fat.

Currently, only a handful of nutritional supplements are designed to offer zero carbohydrates and thus score as low as possible on the Glycemic Index. And of these zero-carbohydrate products, even fewer offer a rich source of complete protein that effectively helps counter the blood sugar spike impact of high Glycemic Index foods.

It is inspiring to note that Glycemic Index is getting some well-deserved attention from outside the diabetic community, where it has helped millions of people eat wisely. Now, dieters and obese people can enjoy the wisdom that this index promotes.

South Beach Diet Or Another Fad Diet?

I have thoroughly researched this diet and am giving you every detail of south beach diet for information.

South beach diet book is founded on the premise that switching to good carbs stops insulin resistance and curbs appetite which leads to weight loss. Also, good fats protect the heart and prevent hunger.

But this is hardly true as you will learn after reading this article.

South beach diet book offers a simplistic solution to weight loss. All you need to do is eat good carbs like whole grains, vegetables and beans instead of eating bad carbs like sugar white breads and potatoes.

South beach diet says, fast sugars are worst for dieters and slow sugars are good.

And how are these foods classified as fast or slow? The Glycemic Index.

According to south beach diet, the food having a high Glycemic Index causes the blood sugar to spike (go up) immedietly after having the meal,whereas the food with a lower GI does not drastically shoot up the blood sugar levels.

But this theory is only partially true. Yes, the foods with high GI are good for diabetics in helping them to keep their blood sugar levels in check, but contrary to popular belief, the glycemic index of a certain food is not the same.i.e. it depends on how the food is processed, stored, ripened and cooked.

Further, south beach diet is formulated on the premise that good carbs like whole grains have a low glycemic index and bad carbs like sugars, white flour and refined grains have a higher GI.

BUT THE TRUTH IS....

Bread is high GI whether whole wheat or white because it is made from finely ground flour.

Pasta is low GI, whether whole or white(thin languine has a high GI as compared to the thick one)

"Instant white" rice is low GI whereas "Uncle bens converted white" rice is high GI.

Take the case of sugars...Glucose is high GI, Sucrose is medium GI and fructose is low GI

This illustrates that recommending foods based on GI is confusing as well as misleading. On top of it all, there is no research to support the claim that the rise in blood sugar by eating high GI foods leads to high blood insulin levels, and that this leads people to overeat.

To summarise...there is no evidence to suggest that eating low GI foods leads to weight loss.

Now lets have a look at the south beach diet menu.

South beach diet book claims that you won't feel hungry while on this diet. This is impossible considering the fact that some of the menus average only 1200 calories, which is too low not to feel hungry.

The diet encourages you to eat seafood, chicken breast, lean meat, vegetables,whole grains, some fruits, beans, low fat cheese, nuts, oils and whole grains. fatty meats, high fat cheese, refined grains, sweets, juice and potatoes.

The choice of foods in this diet plan are somewhat healthy compared to other leading diet plans like ATKINS but restricting the consumption of carrots, bananas, pineapple and watermelon is the worst part of south beach diet.

The meal plan consists of three phases :

Phase 1 of south beach diet :

You are allowed to eat normal size helpings of chicken, meat, turkey, fish and shellfish, vegetables, eggs, cheese and nuts. You can have three meals per day. Desserts, coffee and tea are also allowed.

But for the first 14 days you are not allowed to eat bread,rice,potatoes,pasta or baked goods and even fruits!

Phase 2 of south beach diet :

You can slowly begin to reintroduce carbs into your diet again. The diet advices you to take all the forbidden foods in phase 1 like bread, pasta, fruits etc. in moderate quantities but at the same time not as much as you were having before.

Phase 3 of south beach diet:

This part is the most relaxed. Dr.Agastson says that you can now forget that you are on a diet. He says that now onwards it is just a healthy lifestyle you are used to, and going to adhere for the rest of your life.

All in all, south beach diet is one more money spinning fad diet for the creator of this weight loss program and a phsychological prop(support) for people who are allways hopping from one diet to the other in search of a hollywood like sexy body.

The initial weight loss caused by this diet is on account of calorie restriction and not because of low Glycemic Index or an invisible switch as Dr. Agastson's marketing language wants you to believe.

Your health could be 100 times better without south beach diet weight loss program,if you choose healthy foods like green vegetables,whole grains,fiber rich foods and vegetables.

And if you are eager to lose those extra pounds,why not do it the most natural way with the weight loss principles of Ayurveda medicinal science?

This is the most effective long term,scientifically proven solution to excess fat.

Understanding Low Carb Diets

With all of the conflicting studies and fuzzy interpretation of information, it's no wonder that confusion reigns when it comes to the value and safety of low-carb diets. It seems like heated debates are raging everywhere!

Whether it's Atkins, the South Beach or some other low-carb plan, as many as 30 million Americans are following a low-carb diet.

Advocates contend that the high amount of carbohydrates in our diet has led to increasing problems with obesity, diabetes, and other health problems. Critics, on the other hand, attribute obesity and related health problems to over-consumption of calories from any source, and lack of physical activity. Critics also express concern that the lack of grains, fruits, and vegetables in low-carbohydrate diets may lead to deficiencies of some key nutrients, including fiber, vitamin C, folic acid, and several minerals.

Any diet, weather low or high in carbohydrate, can produce significant weight loss during the initial stages of the diet. But remember, the key to successful dieting is in being able to lose the weight permanently. Put another way, what does the scale show a year after going off the diet?

Let's see if we can debunk some of the mystery about low-carb diets. Below, is a listing of some relevant points taken from recent studies and scientific literature. Please note there may be insufficient information available to answer all questions.

- Differences Between Low-Carb Diets

There are many popular diets designed to lower carbohydrate consumption. Reducing total carbohydrate in the diet means that protein and fat will represent a proportionately greater amount of the total caloric intake.

Atkins and Protein Power diets restrict carbohydrate to a point where the body becomes ketogenic. Other low-carb diets like the Zone and Life Without Bread are less restrictive. Some, like Sugar Busters claim to eliminate only sugars and foods that elevate blood sugar levels excessively.

- What We Know about Low-Carb Diets

Almost all of the studies to date have been small with a wide variety of research objectives. Carbohydrate, caloric intake, diet duration and participant characteristics varied greatly.
Most of the studies to date have two things in common: None of the studies had participants with a mean age over 53 and none of the controlled studies lasted longer than 90 days.

Information on older adults and long-term results are scarce.
Many diet studies fail to monitor the amount of exercise, and therefore caloric expenditure, while participants are dieting. This helps to explain discrepancies between studies.

The weight loss on low-carb diets is a function of caloric restriction and diet duration, and not with reduced carbohydrate intake. This finding suggests that if you want to lose weight, you should eat fewer calories and do so over a long time period.

Little evidence exists on the long-range safety of low-carb diets. Despite the medical community concerns, no short-term adverse effects have been found on cholesterol, glucose, insulin and blood-pressure levels among participants on the diets. But, adverse effects may not show up because of the short period of the studies. Researchers note that losing weight typically leads to an improvement in these levels anyway, and this may offset an increase caused by a high fat diet. The long range weight change for low-carb and other types of diets is similar.

Most low-carb diets cause ketosis. Some of the potential consequences are nausea, vomiting, abdominal pain, and confusion. During the initial phase of low-carb dieting some fatigue and constipation may be encountered. Generally, these symptoms dissipate quickly. Ketosis may also give the breath a fruity odor, somewhat like nail-polish remover (acetone).

Low-carb diets do not enable the consumption of more calories than other kinds of diets, as has been often reported. A calorie is a calorie and it doesn't matter weather they come from carbohydrates or fat. Study discrepancies are likely the result of uncontrolled circumstances; i.e. diet participants that cheat on calorie consumption, calories burned during exercise, or any number of other factors. The drop-out rate for strict (i.e. less than 40 grams of CHO/day) low-carb diets is relatively high.

What Should You Do? - There are 3 important points I would like to re-emphasize:

- The long-range success rate for low-carb and other types of diets is similar.

- Despite their popularity, little information exists on the long-term efficacy and safety of low-carbohydrate diets.

- Strict low-carb diets are usually not sustainable as a normal way of eating. Boredom usually overcomes willpower.

It is obvious after reviewing the topic, that more, well-designed and controlled studies are needed. There just isn't a lot of good information available, especially concerning long-range effects. Strict low-carb diets produce ketosis which is an abnormal and potentially stressful metabolic state. Under some circumstances this might cause health related complications.

The diet you choose should be a blueprint for a lifetime of better eating, not just a quick weight loss plan to reach your weight goal. If you can't see yourself eating the prescribed foods longer than a few days or a week, then chances are it's not the right diet. To this end, following a moderately low fat diet with a healthy balance of fat, protein, carbohydrate and other nutrients is beneficial.

If you do decide to follow a low-carb plan, remember that certain dietary fats are associated with reduction of disease. Foods high in unsaturated fats that are free of trans-fatty acids such as olive oil, fish, flaxseeds, and nuts are preferred to fats from animal origins.

Even promoters of the Atkins diet now say people on their plan should limit the amount of red meat and saturated fat they eat. Atkins representatives are telling health professionals that only 20 percent of a dieter's calories should come from saturated fat (i.e. meat, cheese, butter). This change comes as Atkins faces competition from other popular low-carb diets that call for less saturated fat, such as the South Beach diet plan. Low-carb dieting should not be considered as a license to gorge on red meat!

Another alternative to "strict" low-carb dieting would be to give up some of the bad carbohydrate foods but not "throw out the baby with the bath water". In other words, foods high in processed sugar, snacks, and white bread would be avoided, but foods high in complex carbohydrates such as fruit, potatoes and whole grains, retained.

You Can Lose Weight on a High Carbohydrate Diet

A startling fact is that carbohydrates are not responsible for making people fat. Don't feel too badly though, you are not the only person who was sold on the idea that a high protein, low carb diet was the only way to lose weight.

Here is a simple way to demonstrate this fact. Think about the vegetarians you know, are there any overweight problems among them? The high protein diets rely on a lot of animal fats and proteins, but these vegetarians don't eat them. Startling indeed, isn't it?

Maybe you don't know any vegetarians. They certainly are hard to find, especially in the Midwest, where I live.

You may wonder about the science involved here. After all, many of those folks promoting the low carb diets are medical doctors, aren't they? Being a medical doctor doesn't mean that you don't ever make any mistakes. Besides, the same science that supports the low carb diet also supports the high carb diet. They didn't get it wrong, they just didn't consider the whole story.

That might sound like a contradiction, but it isn't. I'm going to explain why in just a moment. Fist, let me give you the science on this. You most likely are not a biochemist or a physiologist and neither am I. But I have studied the subjects a bit. Don't focus on the technical jargon in the next paragraph, just try to grasp the overall point. You don't need to be a scientist to use common sense and basic reasoning skills. Ready?

Consider this bit of biochemistry. Malonyl -CoA exists in high amounts when there is plenty of metabolic fuel present. Thus, carnitine acyltransferase is inhibited and this in turn prevents acyl-CoA from crossing into the cell’s mitochondria. Another enzyme is inhibited by the presence of NADH and Thiolase is also inhibited by the presence of Acetyl-COA. In short, when a lot of glucose is present, fatty acid metabolism is inhibited.

It is the last sentence that clues us in here. Basically, a cell will not convert fats into energy if there is glucose present. When the cell has carbs and sugar to work on, it will not convert the fat to energy, thus the fat gets stored.

This is why the low carb diets work, with little to zero carbohydrates and subsequently glucose to work on, the fat will be used for energy. This is exactly why the high carb diet works too. When no or little fat is present, it won't be stored as fat.

In addition to this, it is important to realize that it costs the body quite a bit of energy to take carbs and store them as fat. This alone is actually a positive. There really needs to be some form of fat present to make it easier.

This should help you understand that whatever your diet consists of, if you want to remain or get thin, you need to avoid mixing fats and carbs together. A fat consists of a fatty acid head and a carbohydrate tail. This means when you mix your fat and carbs together you are asking for trouble, assuming you care about weight, that is.

So now it should be clear why so many people in North America have a weight problem as the NIH was happy to point out a few weeks ago. Think about the typical American diet. It generally consists of lots of combinations of fat and carbs.

As Dr. Neal Barnard points out in his book, "Foods That Cause You To Lose Weight", It is fat that makes people fat.

Don't want to be a vegetarian? I don't blame you. Really, you don't have to be one. Just quit mixing your proteins/fats and carbohydrates together.

Don't overlook the obvious, there is ton of candy and desserts out there that are a mixture of fat and sugar. Meat and potatoes - perhaps this classic is a serious blunder in seperating proteins/fats and carbs. You can probably come up with dozens of examples of potentially fattening mixtures of food on your own.

There are a number of factors to consider when changing your diet.

Why fad diets don’t work!

The answer is simple...fad diets are not natural.

Fad diet is the term that describes an array of diet approaches used to temporarily lose weight through unsafe and unrealistic methods. Quick fix programs do not work...although millions of dollars are spent each year. These programs offer a quick loss of weight but sadly the weight is gained right back because people return to their old eating habits and old life style.

There are many kinds of fad diets. Avoid those types of diets that recommend a certain nutrient, or combination of foods encouraging you to loss weight fast. Fad diets do not teach lifestyle habits for long-term weight management, they do not help people gain the will power to change a lifestyle with another.

Diets promoting a very low calorie system, approximately 1,000 to 1,500 calories per day and with no exercise program cause the body to become less efficient at burning fat, making it easier to store fat and regained weight each time a diet is stopped. In the long run this fad diets makes a person fatter instead of leaner. Ultimately these fad diets are not safe.

Only your weight and exercise level determines the number of calories that is right for your diet program and only healthy lifestyle habits will maintain long-term weight control. Healthy lifestyle habits include regular exercise, behavior modification, and a healthy, nutritious diet with a wide variety of foods.

People should be aware of their health problems before engaging in a diet program. All diets should include a warning to check with a specialist before trying a diet. Also most fad diets make no mention of physical activity, which is essential in the process of weight loss and some of these diets can actually harm one’s health.

The majority of fad diets involve a 10 day to 1 month period in which your diet is restricted to a select collection of bad-tasting, inconsistent health foods or recipes. The fads diet is generally advising you to completely avoided fats.

Due to water loss from this period, as a reaction to the starvation process, you will quickly lose weight. And, as you continue to starve, your body starts working in order to keep up with the energy needs. But you are still not burning fats and as you avoid fats in your diet, your body will try to preserve the fat that it has in its store. And if you continue your diet up to a month your body will burn its stored fats having no other alternative to stay alive.

After this period the dieter starts getting weaker and he is not able to feel well and perform its normal duties because it requires a lot more effort and time for the body to produce energy from fat rather than from muscle.
At a certain time the dieter is back to his normal eating habit but it will take some time before the reconstruction of your muscle occurs and during this time, the body stores most of the food intake as excess fats. Therefore at the end of the reconstruction process, the dieter is back to his initial weight gaining back the weight he lost in the starvation process and little bit more.

A diet regards the proper nutrition for a normally developed human and it should contain vitamins, minerals, proteins, carbohydrates AND fats. An imbalanced process may cause starvation or excessive reserves of body fat.

By using fad diets in your weight loss process your body will experience both starvation and weight gain in a short amount of time.

Food Intolerance And Low Carb Diets

Food intolerance is a pharmacological reaction to the consumption of certain foods. In many cases, food intolerance may appear to be the side-effect of pharmacological drugs, but in fact, it is generally caused by the consumption of natural foods products, additives, or the combination of both.

The majority of food products that commonly cause food intolerance are high-protein.

As a low carb dieter, you will have abnormally- high exposure to high-protein food, including dairy products and meats, which means your chance of experiencing food intolerances (if you have any) will increase.

In contrast to food allergies, which are easily identifiable because they affect an almost instantaneous reaction of hives, shock, and a range of other symptoms, food intolerances are somewhat harder to identify.

Food intolerance generally has milder affects, such as minor headaches, general irritation, upset stomach, restlessness, and a loss of sleep. This makes it much harder to identify and treat.

If you are new to your low carb diet, you may have already experienced some of these symptoms, but attributed them to something other than food intolerance.

If you have been exhibiting these symptoms for less than three days into your low carb diet, they are more than likely related to withdrawals from caffeine or carbohydrates. They could also be related to dehydration. Conversely, if you have been exhibiting them for more than three days, they are more than likely the result of a food intolerance.

You should immediately start the process of weeding out foods that could be causing the intolerance.

The following is a list of foods you may be consuming on your low carb diet that are likely perpetrators: eggs, nuts, milk, fish, shellfish, pork, bacon, chicken, cheese, and tomatoes.

You should try to remove one of these from your low carb diet at a time. If you cannot solve your intolerance problem within a week, it would be wise to get off of your low carb diet and contact a physician to determine the source of your intolerance.

Diverticulitis And Diet

What Is Diverticulitis?

Diverticulitis is another one of those conditions that has followed from industrialisation, and a fundamental change in eating habits to a diet of processed food. The condition emerged after milling became commonplace in Western countries, starting in the US. Milling grains strips out valuable fibre, and since the early 20th century a shortage of fibre in diets has been commonplace amongst the American, and other Western, population.

Diverticulitis actually follows on from a condition called diverticulosis, which tends to come with age, particularly over 60. Diverticulosis is quite common, and past the age of 60 about half the population have this condition. With diverticulosis people experience the formation of small pouches in the intestinal tracts. These pouches are called diverticula. They are, in themselves, harmless, and most people never know they have them.

If diverticula become inflamed or infected, however, then the patient will experience pain in the abdominal region. Only a relatively small percentage of people with diverticulosis develop diverticulitis, and many of these are mild cases which can be treated with rest and diet change. More serious cases may require surgery.

What Should A Diverticulitis Diet Include?

If diverticulitis has been diagnosed by your doctor, and is confirmed as a mild case, then your doctor will probably recommend some dietary changes. Although a shortage of fibre in the diet over a number of years may have caused the condition, once you have it, your doctor may ask you to cut down on fibre even more for a few days, as it may aggravate the pain.

Your treatment is likely to include antibiotics to kill the infection, and it is vital you finish your course and take your doctor's advice. In about half of cases of diverticulitis, the patient will be hospitalised; the other half will be treated at home. So it is wise while you are home to stick to the diverticulitis diet recommended by your doctor.

When the infection is cleared and the diverticulitis is no longer a problem, then you will be able to concentrate on prevention, but again you should take your doctor's advice.

Diverticulitis Prevention Diet

The cause of diverticulosis is a diet too low in fibre. The prevention of the condition should therefore attempt to redress that balance. The diverticulitis diet should be well balanced, but include high fibre foods such as fresh fruits, vegetables and whole grains. I am sure you have heard that before when a healthy diet is mentioned. Such a diet can help prevent a number of chronic diseases.

A fibre supplement may be helpful. I have used psyllium for more than a decade, and find it an excellent source of soft fibre, and for cleansing the digestive system it is ideal, as the psyllium forms a gel like texture when mixed with water.

The water itself plays an important role in producing a soft stool, and especially when mixed with fibre. So, you should have plenty of water in your diverticulitis diet. Throw in half an hour exercise a day, and your bowel and digestive system should keep in good shape.

Atkins and South Beach Diets Compared

Low-carb diets have been in the market for quite some time now. Two of the most common these days are the Atkins and South Beach Diet.

Beginnings
Both were developed by medical doctors (cardiologists) who -- according to reports -- were trying to help Americans lose weight given their high carb diets.

Atkins Diet was the first to be developed and is thus, the more popular. It was developed by the late Dr. Robert C. Atkins as early as the 1972 but became more widely popular -- despite the oppositions -- in the 1990s.

Dr. Arthur Agatston, also a cardiologist but from Mount Sinai Cardiac Prevention Center in Miami Beach, Fla., is known as the father of the South Beach diet. His work came a lot later through his book: "The South Beach Diet: The Delicious, Doctor-Designed, Foolproof Plan for Fast and Healthy Weight Loss" published in 2003.

Similarities
Both popular diet plans advise dieters to avoid carbohydrates and follow stringent steps to ensure that the significant weight lost during the program does not come back.

Both start with the so-called induction phase where the body of the dieter is "trained" for the routine.

Both diet plans come with suggested food lists where dieters can mix and match foods to suit their tastes. Of course, like other diet plans, both plans advise dieters to stay away from food not included in the lists.

Among the "dont's" in Dr. Atkins' list are fruit, bread, pasta, grains, starchy vegetables, nuts, seeds, legumes, and some dairy products except cheese, cream, and butter.

Aside from fruit, bread, pasta and vegetables, South Beach dieters are also advised to stay away from potatoes, cereal, rice, and corn, especially for the first two weeks of the induction or introductory period. After this period, these can be slowly re-introduced into the body, albeit in smaller amounts.

Both diet plans have a lifetime "maintenance" phase where hopefully dieters will be so accustomed to either plan that they hardly recognize that they are dieting at all.

Differences
While both diet plans restrict carbohydrate intake, the South Beach diet is said to be more forgiving by not totally eliminating carbs. It distinguishes between "good" and "bad" carbs and even "good" and "bad" fats. South Beach encourages intake of "good" carbs and fats.

Low-sugar carbs with low glycemic index are "good" carbs under the South Beach plan. Food rich in fiber are also recommended.

Atkins's diet routine helps the body to burn fat instead of carb. The goal is to help the dieter achieve good health.
Atkins's diet plan involves four phases while the South Beach plan has three phases.

In both plans, the introductory stage aims to condition the body for some changes to prepare for the program.

In Atkins diet, the body is trained to burn fat instead of sugar to help curb the cravings for sugar and break addiction to some foods.

In South Beach diet, the initial phase involves cutting on high-carb foods, which can be gradually re-introduced in small amounts in the next phase. In this case, South Beach debunks myths that this approach prevents dieters from getting healthy mix from all food groups.

Atkins dieters go through the next following phases: ongoing weight loss, pre-maintenance and lifetime maintenance.
The last two phases of South Beach diet are called re-introduce the carb and diet for life.

What's key in the maintenance phase in Atkins is to keep portions of food at small amounts.

Atkins diet guarantees no hunger deprivation because its long-term goal is healthy diet.

South Beach's promise is a "change in the way of eating," with the dieter not recognizing at all that he is on a diet.
Summarizing the Diets

Atkins Diet
Developed by cardiologist Dr. Robert C. Atkins in 1972, with his “Diet Revolution”, a high-protein, high-fat, low-carbohydrate diet.

The program focuses on a low-carbohydrate diet.

The Program has 4 phases:
1. induction phase (train the body to burn fats instead of carb)
2. ongoing weight loss
3. pre-maintenance
4. lifetime maintenance

South Beach Diet
Developed by cardiologist Dr. Arthur Agatston of Miami, Florida, who in 2003, published the book “The South Beach Diet: The Delicious, Doctor-Designed, Foolproof Plan for Fast and Healthy Weight Loss".

The program distinguishes between “good” and “bad” carbohydrates, and “good” and “bad” fats.
Take in “good” carbs and fats.

The program has 3 phases:
1. 2-week introductory or induction phase (strictly no carbs)
2. re-introduce the carbs
3. diet for life
