Hormonal

Low-Glycemic Index (GI) diets promote greater weight loss, better insulin regulation, and lower weight regain compared to high-GI or conventional diets, primarily by enhancing satiety and minimizing postprandial insulin secretion.

Choose carbohydrates that digest slowly (low GI), such as vegetables, legumes, and whole grains, rather than refined grains and sugars. This helps control hunger and insulin levels, leading to better weight loss and maintenance.

ModerateSupportsMEDIUM confidence
diets based on low-GI foods may enhance weight control because they promote satiety, minimize postprandial insulin secretion, and maintain insulin sensitivity... patients who followed a low-GI diet during an 8-week energy-restricted period registered higher weight loss (7% of the initial body weight) than those included in a conventional diet (5% of the initial body weight)
