Macro partitioning

A 6-month low-calorie, high-protein diet (35% of total calories from protein) improves glucose metabolism, body composition, and cardiometabolic profiles in subjects with prediabetes or type 2 diabetes and overweight/obesity, regardless of whether the protein source is primarily animal or plant-based.

If you have prediabetes or type 2 diabetes and are overweight, switching to a diet where 35% of your calories come from protein (whether from meat, fish, eggs, beans, nuts, or soy) and restricting your total calories by 30% can significantly improve your blood sugar, weight, and heart health markers. It does not matter if you choose animal or plant proteins; the key is the high-protein, low-calorie pattern itself. Stick to this for at least 6 months for best results.
