The Truth Behind the Effectiveness of Low-Carb Diets

The effectiveness of low-carb diets for weight loss lies in the fact that they help people eat fewer calories, rather than any metabolic magic. Low-carb diets can lead to short-term weight loss due to their satiating effect and the elimination of calorie-dense foods. However, in the long run, adherence to any diet is what matters most. When it comes to the calories-out part of the equation, strictly controlled trials have shown that the macronutrient composition of a diet, including carb content, does not significantly impact energy expenditure. Ultimately, weight loss on low-carb diets is primarily attributed to consuming fewer calories.
