The Claim
In middle-aged adults with overweight or obesity, a low-carbohydrate high-fat diet without calorie restriction leads to total weight loss (6.1 kg) comparable to that achieved with a calorie-restricted low-fat diet (3.1 kg) over 15 weeks, suggesting that macronutrient composition may independently influence energy intake and body weight regulation regardless of prescribed caloric targets.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating fewer carbs and more fat—without counting calories—can help people lose about as much weight as eating less fat and cutting calories. This suggests that what you eat might matter just as much as how much you eat.
See the scientific wording
A low-carbohydrate high-fat diet without calorie restriction is associated with similar total weight loss (6.1 kg) as a calorie-restricted low-fat diet (3.1 kg) in middle-aged adults with overweight or obesity over 15 weeks, indicating that macronutrient composition may influence energy intake and body weight regulation independently of prescribed caloric targets.
