Flat Belly Diet

This diet was invented by Cynthia Sass and Liz Vaccariello who explained their loss-weight program in the book “Flat Belly Diet!”, first issued in 2008. In the book its authors present a 32-day eating plan that, as they assure, gives the possibility to lose up to fifteen pounds and drop belly fat. The book spent twelve weeks on the bestseller list of The New York Times and the Flat Belly Diet got a great number of fans.

How Does It Work?

The Flat Belly Diet is based on the following main principles:

  • You should eat foods containing monounsaturated fatty acids (MUFAs)1 at every meal.
  • You should have four meals per day.
  • You should eat every four hours during a day.
  • Every meal should have 400 calories (daily intake: 1600 cal).

The diet’s creators claim that MUFAs demolish belly fat and at the same time prevent overeating. Monounsaturated fatty acids can be found in seeds, nuts, chocolate, olive oil, avocados, and some other foods.

The Flat Belly Diet starts with a four-day period, called Anti-Bloat Jumpstart, with the specific menu. This phase prepares the dieter for the regular eating plan that begins on the fifth day.

Physical exercises are not obligatory on the Flat Belly Diet but they are encouraged.

What Are the Benefits?

Of course, if you consume no more than 1600 calories per day, you will lose weight and you waist will become thinner. But it is not proved that this diet targets belly fat specifically. Neither there is any scientific evidence that monounsaturated fatty acids have special effect on it. What is more, if you lose fifteen pounds in a month, it will mostly be water weight and you will most likely regain it.

The Flat Belly Diet is based on eating monounsaturated fats. They are healthy fats which are good for cardiovascular health. They reduce cholesterol levels and blood pressure. MUFAs also control insulin and blood sugar levels, so they lower the risk of having diabetes.

Are There Any Health Risks?

No side effects or risks connected with the Flat Belly Diet have been proved. Anyway, dieters who have health conditions should consult a doctor before starting this program.

What Foods Should Be Eaten?

In fact, the menu of the Flat Belly Diet is very similar to the one used by Mediterranean dieters. It consists of fruits, whole grains, fish, lean meat, vegetables, olive oil, and legumes.

There is a special menu for the first four days of the Flat Belly Diet. It suggests skim milk, cucumbers, chicken breasts, baby carrots, tilapia, and some other foods. During this period dieters should also drink so-called “Sassy water” (pure water with cucumber, ginger root, mint leaves, and lemon). It is prohibited to eat salt, processed food, beans, onions, broccoli, bagels, bananas, and pasta.

After the anti-bloat period, dieters eat four times per day, getting 400 calories per meal. At every meal, it is necessary to eat foods containing monounsaturated fatty acids. They are seeds, avocados, nuts, chocolate, etc.

Bottom Line

The Flat Belly Diet has numerous advantages. It really helps to lose several pounds. It is customizable without effort, pretty cheap, and easy to follow. You will have no problems with finding delicious recipes. The diet has no health risks and is good for your heart.

But do not forget that it is better to lose no more than one – two pounds in a week. Otherwise, the lost weight will probably be regained.
