Key Takeaway: When calories and protein are equated, randomized metabolic ward trials show no clinically significant difference in body fat loss between low-carb and low-fat diets. Adherence and personal preference are the true differentiators.
The Insulin-Carbohydrate Model vs. Energy Balance Model
The Carbohydrate-Insulin Model proposed that carbs drive insulin, which traps fat in adipose tissue. However, strictly controlled metabolic ward studies by Dr. Kevin Hall demonstrated that fat loss is equivalent across high-carb and low-carb protocols when net caloric deficit and protein are matched.
How to Choose Your Split
- Choose Higher Carbohydrate: If you engage in high-intensity resistance training, CrossFit, or sprinting.
- Choose Higher Fat: If you prefer richer, savory foods and experience better glycemic stability on lower carb intakes.
