Macro partitioning
Macronutrient composition (low-carb vs. low-fat) has no significant difference on weight loss outcomes when total caloric intake and adherence are controlled.
Don't obsess over whether you should be low-carb or low-fat. The most important factor is that you eat fewer calories than you burn. You can achieve this with almost any dietary pattern (Mediterranean, low-carb, low-fat) as long as you stick to it and maintain a calorie deficit.
StrongRefutesVERY_HIGH confidence
Reduced-calorie diets result in clinically meaningful weight loss regardless of which macronutrients they emphasize.
Why this rating
Supported by multiple large RCTs (Sacks, Shai, Gardner) and meta-analyses cited.

More from this paper
- Reducing dietary energy density (consuming larger portions of lower-calorie foods) improves satiety and aids weight loss maintenance, regardless of total caloric intake in the short term.Good
- Weight loss triggers compensatory metabolic adaptations (hormonal and energy expenditure changes) that promote weight regain, making long-term maintenance difficult.Good
