Combining low-carbohydrate intake (26% of calories) with calorie restriction (1200-1500 kcal) yields the greatest reduction in BMI, body weight, waist circumference, and body fat compared to either intervention alone.
For the fastest and most comprehensive weight loss, combine a low-carbohydrate diet (26% of calories from carbs) with a moderate calorie restriction (1200-1500 kcal/day). This dual approach was shown to reduce BMI, body weight, waist circumference, and body fat more effectively than either strategy used alone. This is the most potent dietary intervention for overweight/obese individuals in this study.
The combination of restricting carbohydrate and total calorie intake may augment the beneficial effects of reducing BMI, body weight, and metabolic risk factors among overweight/obese individuals.
Why this rating
Same high-quality RCT design as N1.
