According to Dr. Fuhrman , in Italy known for a vegetarian-based diet that took his name, or the Fuhrman diet , fast diets are not effective, and are indeed the cause why people continue to gain weight.

Let’s see what are the reasons why not to choose a fast diet according to the famous doctor.

Why fast diets aren’t effective

• The dr. Fuhrman   explains that most fast diets involve eliminating something from a normal diet.

  Many of us are used to a balanced diet, in which excess calories and a sedentary lifestyle determine a weight gain that we will call “flab”. When we try a fast diet to lose the flab, nine times out of ten we will be advised to eliminate certain foods that we normally eat: for example carbohydrates, if we try a protein diet. Or: all dairy products. Or again: pasta.

  Fast diets, to be effective, leverage the motivation of those who want to lose weight. Initially we are all very motivated to get rid of the flab!
  We would be capable of superhuman efforts, and therefore we welcome the sacrifices: no dairy? Let’s go to the cheeses. No sweets? Robetta, what do you want me to be saying goodbye to sugar for a week or two?

  Subsequently, even after just two or three days, it is our head that rebels. Maybe yes, we have results, and the great thing about fast diets is that they go away quickly, so from the following week we could resume eating normally. And there the donkey falls.

  Almost everyone, after a fast and drastic diet, with the elimination of certain foods, returns not only to eating normally, but to excess precisely in the foods they had eliminated.
  It is a clear compensation mechanism . However, metabolism is a self-regulating system. If after a fast diet we return to eating as before, the flab will not only come back to besiege us, but we will also have a few extra pounds. For this reason, those who return to a balanced diet after a high-protein diet regain all the weight lost within a maximum of two or three years.

• Fast diets don’t teach us to eat better.

  The diet we decide to do is a diet to follow for life. Can we ever eliminate foods for life? And if so, which ones and to what extent? What will happen after a month, two or a year? Will we be able to continue eating like that?

• Another problem for those who go on a diet and fail is hunger.

  Fast diets are often drastic. The consequence of a diet that focuses on fruits and vegetables but eliminates all fatty foods or complex carbohydrates, for example, is that it will make me incredibly hungry. But what kind of hunger? Not a real hunger, the one for which I need to feed myself, but a fictitious, toxic hunger. In short, it would be what we call the munchies, the hunger for foods that stimulate the production of dopamine in the brain, which is why we feel better eating them. It is a hunger that we can overcome with the right precautions, but which increases if we make reckless sacrifices. Many people, following drastic and fast diets, have begun to have borderline eating behaviors, often a wake-up call.
  For example, bingeing and then resuming the diet. It is an exasperating and very bad mechanism in terms of health. An effective diet does not have to drive us crazy, nor do we become victims of toxic hunger.

  But then, if fast diets are not effective, which diet allows us to lose the flab without also losing reason?
  Well, an example is given by the food plan that dr. Fuhrman illustrated in his book “Eat to live”: eat (prefer) foods with a high nutritional content over calorie content. In short, foods that nourish us and give us energy, but without just giving us energy without nutrients. Then the vegetables, legumes, fruit and unrefined cereals. It would be enough to increase the consumption to lose weight without giving up the foods we love every now and then.
  One way to do this is with the famous 80/20 diet.
