Macro partitioning
A very-low-carbohydrate, high-protein, high-fat diet (Atkins) produces significantly greater weight loss and more favorable metabolic risk factor changes at 12 months compared to low-carbohydrate (Zone), low-fat/high-carbohydrate (LEARN), and very-low-fat (Ornish) diets in overweight premenopausal women.
If you are an overweight premenopausal woman looking to lose weight, a very-low-carbohydrate diet (like Atkins) may offer greater weight loss and better metabolic improvements (like lower triglycerides and blood pressure) compared to low-carb, low-fat, or high-carb diets over a 12-month period. Focus on restricting carbohydrates to 20-50g per day, ensuring adequate protein and fat intake, and participating in structured support programs to maintain adherence.
In this study, premenopausal overweight and obese women assigned to follow the Atkins diet, which had the lowest carbohydrate intake, lost more weight and experienced more favorable overall metabolic effects at 12 months than women assigned to follow the Zone, Ornish, or LEARN diets.
Why this rating
Randomized controlled trial with a relatively large sample size (n=311) and good retention rates (76-88%), though limited to a specific demographic (premenopausal women).
