Abstract

In the global fight against diabetes and metabolic disorders, dietary interventions such as low-carbohydrate diets (LCDs) have gained traction for their ability to stabilize blood glucose (BG) levels and improve insulin sensitivity. The Japan Low Carbohydrate Diet Promotion Association promotes three levels of carbohydrate restriction: super, standard, and petite LCDs, which contain 12%, 26%, and 40% of total calories from carbohydrates, respectively. Whey protein consumed as a premeal supplement can diminish postprandial BG elevations and could serve as an excellent adjunct to meals containing higher levels of carbohydrates, such as the petite and standard LCDs.
