The Claim
In middle-aged adults with overweight or obesity, both low-carbohydrate high-fat diets and calorie-restricted low-fat diets are associated with the preservation of total body and appendicular lean mass over a 15-week period, suggesting that either dietary approach can support the maintenance of lean mass during weight loss in this population.
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.
If you're a middle-aged adult with extra weight, eating either a low-carb high-fat diet or a low-fat diet with fewer calories can help you keep your muscle while losing weight over about 4 months.
