Macro partitioning
A combined high-protein (25% energy) and low-glycemic-index (LGI) diet is superior to low-protein/high-GI diets for maintaining weight loss and improving insulin resistance (measured by TyG index) after an initial energy-restricted weight loss.
If you have recently lost weight, switch to a maintenance diet that is high in protein (around 25% of calories) and low in glycemic index (low-GI carbs). This specific combination helps you keep the weight off longer and improves insulin sensitivity better than diets low in protein or high in glycemic index. You do not need to count calories strictly; focus on the quality of your protein and carbohydrate sources.
In comparison with the LP/HGI diet, the HP/LGI diet induced a greater BMI loss (p < 0.05). ... A HP/LGI diet is beneficial not only for weight maintenance after a LCD, but is also related to IR amelioration as assessed by TyG index changes.
Why this rating
Randomized controlled trial (DIOGenes project) with a large sample size (n=744) and rigorous statistical analysis, though focused on a specific post-weight-loss maintenance phase.
