Diets are ineffective and dangerous to health and it is time to assess the risks of these treatments, which in many cases are followed without a medical notice and sometimes even in the absence of overweight. But what are the dangers that nearly a quarter of adults are exposed when trying to lose a few pounds? This is the question that a working group of scientists and nutrition experts tried to respond carefully dissecting most popular diets commonly followed in the United States.
All food plans and diets, without exception, cause nutritional imbalances whose health consequences may be more or less severe. The recommended dietary intake is almost never met. In 80% of cases, higher protein intakes are recommended in more than 50% of cases for fat intake and in almost all diets for carbohydrate intake. Eight out of ten diets lead to deficiencies in fiber and generally the intake of vitamins and minerals are inadequate. Often salt intake is too high.
Main result, the practice of most popular diets causes profound changes in the body’s energy metabolism. Result: As soon as the treatment is stopped, weight regain is almost inevitable, and possibly more severe! The report states that 80% of people regain lost weight in the year following the end of treatment.
The main health risks are:
– A loss of muscle mass, and by hence a weakening
– A decrease of the osseous capital, with the risks of osteopenia and fractures it induces
– Heart rhythm disorders and cardiovascular risk, for very low-calorie diets, cases of gallstones, and even sudden death
– Digestive problems, including constipation, but also an increased risk of colorectal cancer associated with deficiencies in fiber
As for the psychological and behavioral consequences, they are not left behind. The report underlines particularly the risks of depression and bad self-esteem which generally reflect chess at repetition of diets, as well as disruption of physiological signals of hunger and satiety which are fairly frequent.
In conclusion, the report points to the importance for people wanting to lose weight, with a medical supervision, but also the physical activity needed to reduce the risk of resumption of pounds. You must remember that nothing can replace a balanced and varied diet, and finally, that obesity is a chronic disease that requires treatment by specialists.
