Skim Milk Overview

Skim milk is cow’s milk with nearly all fat removed, leaving lactose as the primary calorie source. Despite being lower in calories, skim milk is high in carbohydrates and raises blood sugar more quickly than higher-fat dairy. It is not suitable for low-carb, keto, or diabetic-friendly diets.
