The Flash diet would be included in the list of miracle diets and makes official claims out of legality, as it promises the disappearance of the feeling of hunger and ensures a monthly loss of 7 to 10 kg per month . That is why it is part of our ranking of the five least recommended diets ”, says Rubén Bravo, dietician spokesman for the European Medical Institute of Obesity (IMEO) .
All protein-cut diets, based on weight loss through ketosis, with or without the use of protein-based meal replacers, come primarily from France.
“ It is a regimen in phases and based on protein products , which is why it is based on a very expensive diet and not suitable for all budgets. Nothing really new is invented; Protein-based ketogenic diets based on products marketed by many brands have been on the market for several decades and have proven ineffective in the medium and long term, “says Bravo, adding that they are designed to” make cash “with minimal effort on the part of the therapist, with which they are really profitable – large income for a short time invested.
The Flash diet is divided into three perfectly designed stages:
A very restrictive first stage designed to cause ketosis in the patient based on protein , fat reduction and the elimination of fruits, cereals, legumes. Try to avoid malnutrition based on more food supplements like vitamins, minerals, fatty acids. This phase is not healthy for the body, it has important side effects such as constipation, bad breath, headache, extreme hunger and dry skin.
A second stage where little by little a very low amount of natural food is incorporated, a large amount of protein and multivitamin products continue to be maintained. Fats (healthy or not) are still excessively restricted, as are fruits, legumes or whole grains and their derivatives.
In the third stage , we try to undo the metabolic disaster created by trying to avoid the rebound effect, the anxiety peaks caused, the loss of massive muscle mass and the tendency of our body to store, in the form of body fat, healthy carbohydrates. and fats ingested in the healthy diet.
What the ‘new Flash 2020 diet’ adds or changes
After the first book on the Flash diet, the second incorporates the new update with food substitutes in the five daily intakes, reducing them in the following phases, and some recipes to make this ” social anti-life diet , not healthy and with rebound effect more bearable” almost insured, ”says the member of the European Medical Institute for Obesity.
Nutritional deficiencies and health risks
According to Bravo, “of course this type of diet can cause nutritional deficiencies, and therefore it tries to avoid it by adding a significant amount of vitamins, minerals and fatty acids in pill form.”
The expert mentions a considerable list of health risks of the Flash diet:
- Constipation
- Halitosis
- Dry Skin
- Hair loss
- Renal problems
- Headaches
- Supports eating disorders
- Rebound effect
- Loss of muscle mass
- Anxietyattacks
- Insomnia
Learn to eat and that learning lasts a lifetime
Bravo recalls that learning to eat consists of having an eating plan adapted to the personal characteristics of each patient, designed with the aim of maintaining and preventing an optimal state of health and correct body composition.
” When the habit is deeply acquired , the right decisions are made in the area of food without having the feeling of ‘being on a diet’, but simply taking care of yourself, ” says the IMEO spokesperson. “Any long-term plan must take into account social life, food tastes, schedules and limitations, and the teaching of basic concepts in nutrition and healthy lifestyle, in order not only to take it yourself, but also to guide others ”, he concludes.
