A low glycemic index diet and sufficiently rich in protein could avoid gaining weight after a mild hype diet.
The expert: Angélique Houlbert, dietician-nutritionist, author of I laughed with the IG Ba diets
The World Health Organization defines obesity as a morbid accumulation of body fat often endangering health. Obesity affects more than a billion people worldwide and predisposes to the appearance and progression of type 2 diabetes and cardiovascular disease. Indeed, the resistance to insulin (IR) associated with obesity is closely linked to the incidence of diabetes and unwanted cardiovascular accidents. “It is therefore importantsaid Angélique Houlbert, author of I sleep with the low IG diet,, To have levers allowing overweight or obese people not only to lose weight, but not to regulate. However, most of the “flash” weight loss diets are certainly losing weight, but in most cases, this weight is often used to stop the diet. A low glycemic index diet could play this role, as shown in this study. “
The study and its results
The Diet study, Obesity and Genes (Diogenes) is a study of pan -European, multicenter, randomized and controlled food intervention on overweight or obese volunteers. It has just evaluated the effects of the glycemic index and food proteins on weight recovery after a limited calorie program.
Patients who have lost, thanks to a hypocaloric diet, at least 8 % of their initial weight 8 weeks after the start of the study were assigned randomly to follow for 26 additional weeks one of the five regimes without limitation of following calories:
- Rich in protein with high glycemic index (GI)
- Rich in protein with low GI
- poor in protein with high GI
- Low protein with low GI
- control
Results : Compared to the low protein and with high IG diet, the high protein diet and with low GI leads to a larger body mass loss and an improvement in insulin resistance measured by the Tyg index, a composite marker of fasting blood sugar and triglycerides.
Conclusions: a diet rich in protein, with low GI is beneficial not only for maintaining weight after a drastic weight loss, but is also linked to the improvement of insulin resistance
The expert’s opinion
“”The most effective diet in terms of weight maintenancesaid Angélique Houlbert, is that with low IG, which is a factor in improving corpulence and insulin sensitivity, as has been verified in many studies. It is also rich in protein, with 25 % of the total energy intake. A high protein intake has shown weight loss advantages in several trials.“Proteins promote thermogenesis, greater satiety at meals and better preservation of lean mass.”Food proteinshe, she underlines, Like low IG diets have been associated with improvements in glucose homeostasis and insulin sensitivity. In addition, diets moderately rich in protein and low GI could lead to eat less. “Low proteins and GI also have anti-inflammatory effects.
