Higher dietary protein intake (25-30% of daily kcal) improves cardiometabolic health markers, including insulin sensitivity and blood pressure, particularly when combined with energy restriction or specific protein sources like milk protein isolate.

If you are insulin resistant or overweight, increasing protein to 25-30% of your calories (especially from sources like milk protein or lean meats) alongside a calorie deficit can significantly improve your blood sugar control and insulin sensitivity. Focus on the quality of the protein source and the overall food matrix.
