Hormonal

Adopting a low-glycemic index (GI) or low-glycemic load diet promotes greater weight loss and improves metabolic health compared to conventional low-fat diets, primarily by modulating post-prandial insulin and glucagon ratios to favor fat oxidation and preserve lean body tissue.

To manage weight and metabolic health, prioritize carbohydrates that digest slowly. Replace refined grains, sugars, and processed snacks with legumes, whole grains, non-starchy vegetables, and nuts. This approach helps stabilize blood sugar and insulin levels, reducing hunger and promoting fat loss more effectively than simply reducing fat intake alone.

Weight-reducing low GI diets, by contrast, may have more favourable effects on appetite and long-term metabolism, improving the probability of success.
