South beach diet, sounds weird right? Don’t worry, the name was given after an elegant Miami beach where it formed. yes that’s right we are talking about the same diet which has been circling around for some time now along with the military diet.

It was named the south beach diet in the 1990s because the developer of this diet is Dr. Arthur Agatston, a known cardiologist who used to practice in South Beach area at that time. He developed it with the help of a dietitian Marie Almon.

What is South Beach Diet?

The story isn’t much but what inspired him is that he felt this diet should be formed was mainly his patients. This is surely different from a low calorie diet plan or a ketogenic diet.

Agatston noticed that the patients who tried the Atkins Diet got successful in losing some weight and belly fat, whereas the patients who were on a low-fat, high-carb diet still struggled to lose weight or see any noticeable change.

But in the Atkins Diet, there was a high level of saturated fat , and Agatston was not satisfied with the choice, especially when it came to people with heart disease.

More so, he wasn’t a believer in restricting high-fiber foods in the diet with “good carbs,” which were whole grains and fruits.

Dr. Agatston strongly desired to form a diet that would allow the overweight, pre-diabetic and diabetic patients to lose weight quickly and easily by also preventing any heart diseases.

So in result, he created the South Beach Diet, which comprises of lean proteins, unsaturated fats, and low-glycemic-index carbs.

What is Glycemic Index?

Glycemic index is a score between 1 to 100 assigned to foods based on how quickly they are converted to glucose and become part of blood rise blood glucose level. Since carbs are the fastest foods to be digested, therefore, Glycemic Index (GI) is assigned to carbohydrates only.

Glycemic index is very important for diabetes patients because high GI foods quickly raise blood glucose level which is not good for them.

You can see glycemic index of some of the common foods here.

Why South Beach Diet Works?

When Agatston tried the diet himself, he was able to lose weight successfully and some belly fat as well, so he decided to prescribe it also to his patients, who got similar outcomes.

It was made for heart patients, but after observing the results, everyone started following the south beach diet, and it started getting popular day by day.

When he saw the people’s keen interest in his diet, Dr. Agatston finally published The South Beach Diet in 2003, and it suddenly turned into a bestseller all over the world.

He also wrote some other good books like the south beach diet cookbook and the south beach diet supercharged, which also gained a lot of popularity as a second edition of the first book.

While selecting the right carbohydrates, it also restricts you from eliminating some specific carbohydrates which are high in the Glycemic index score (Gl).

Research has shown that foods with high glycemic index promote overeating which may cause weight gain. (1)

It has also been shown that introducing low GI foods in diet improves lipid profile and better blood glucose regulation. (2)

A study published in Clinical Nutrition journal has found a strong association between foods with high glycemic load and belly fat. (3)

This diet is not a typical diet with a reduction of all the carbs and fats. In fact, it encourages to choose the right and healthy foods for yourself like lean proteins, fresh fruits, whole grains, vegetables, and olive oil.

These carbohydrates come into refined forms, such as white bread or sugar. These simple carbs satisfy your stomach and digest quickly for the time being, but after some time, the hunger returns because you don’t get a whole meal or proper nutrients.

Eating carbohydrates which are unrefined is the best option and highly recommended because these digest slowly while giving you the feeling of being full for a long period.

So this way you eat less but healthy.

Is South Beach Diet Safe? 

Yes, the south beach diet is safe to do as there are no extensively restricted guidelines to follow, encouraging you to adopt a healthy and balanced lifestyle, and until you follow the rules as they are set.

But if you restricted yourself more than the diet recommends, it might result in health issues.

Downsides

Like every other diet, south beach diet also has its downsides. These cons are mostly during phase 1 of the three phases of the diet.

The first phase is considered very restrictive, as even fruits are not allowed in it. It will keep the body from having various essential nutrients.

The first phase usually lasts for 2-3 weeks, and stopping fruit intake for this long can result in glucose deficiency. Low sugar levels can also cause a headache or dizziness.

Milk has calcium, and it is advisable to have at least one glass of milk every day for balanced calcium levels. Restricting dairy can cause low calcium levels and can result in bones feeling weak and can lead to pain in joints too.

The weight loss process is very rapid, which is not suitable for many people. The body can feel very fatigued and fragile if you lose weight this fast.

You are very likely to gain it back at the same rate to this way, as feeling tired and your body’s lack of nutrients might put you to overeating.

Also, the weight that is lost very fast can only be water weight or loss of muscle, and there is no proper evidence of long-term weight loss.

Some people consider this diet to be more time and money consuming as it is complex, and most things are up to the dieter. Protein-rich foods are also more costly than others.

The south beach diet depends on the glycemic index for the choice of foods. The glycemic index can change depending upon the way the food was cooked, the size, and a lot of other factors. So it has been criticized for not being a precisely reliable way to make food choices.

There is also no name of exercise in it too. Just dieting with very low activity levels will not promote healthy weight loss. It is just going to make you weak and lazy.

The Bottom Line

South beach diet is a comparatively better diet plan because of its emphasis on healthy foods. And secondly it is backed by science as well so it is not definitely a fad diet.

Every diet plan has different effects on different people, so you might feel like this one is for you. Experiment for yourself if you are still struggling about what diets work, and only then you will know. Also, speak to your doctor before starting any diet.

 This diet is sustainable and good for patients as well as people in general if they follow its specific set of rules. Thought it is not exactly a low carb diet plan but it is in sync with eating.
