Macro partitioning

Low-carbohydrate diets (5-25% energy from carbohydrate) improve cardiometabolic markers (weight, HDL, triglycerides) in healthy adults over 12 weeks, with greater carbohydrate restriction yielding larger improvements in HDL and triglycerides.

Adopting a low-carbohydrate diet (5-25% of calories from carbs) for 12 weeks can improve your weight, waist size, and key blood markers like HDL and triglycerides, even if you don't change your total calorie intake. While stricter diets (5% carbs) yield the best blood marker improvements, moderate restriction (15-25% carbs) is easier to stick to and still provides significant health benefits.
