Energy balance

Low-carbohydrate weight-reducing diets produce greater short-term weight loss (3-12 months) than balanced-carbohydrate diets in overweight/obese adults without type 2 diabetes, but this advantage disappears after 12 months.

If you want to lose weight quickly, a low-carb diet might give you a slight edge over a balanced diet in the first year. However, after a year, it offers no advantage over a balanced diet. Choose the diet you can stick to, as long-term weight loss is similar regardless of carb intake.

Low-carbohydrate diets result in greater weight loss than balanced-carbohydrate diets at 3 to < 12 months, but there is no difference at ≥ 12 months.
