Energy balance
Low-carbohydrate/high-fat diets produce greater short-to-medium term weight loss than low-fat/high-carbohydrate diets, primarily due to spontaneous energy restriction rather than a unique metabolic advantage.
Low-carb diets often lead to faster weight loss in the first 6 months because they help you eat less without counting calories. This is likely due to reduced hunger and food monotony, not a magical metabolic shift. If you prefer this way of eating, it is effective, but you must still manage your total energy intake for long-term success.
Many short-term studies suggest that individuals on low-carbohydrate diets voluntarily reduce their food intake (Volek et al. 2000)... The analysis of the differences in weight loss in this trial demonstrates an overall greater energy deficit in the low-carbohydrate group, which contrasted with the instructions to reduce energy intake in the conventional-diet group (Foster et al. 2003).
Why this rating
Supported by multiple randomized trials (Foster, Brehm, Stern, Yancy) showing consistent short-term superiority.

- Very-low-energy diets (VLED) provide greater short-term weight loss than moderately energy-restricted diets, but do not yield superior long-term weight loss or maintenance.Good
- High-protein diets (25-30% energy) improve satiety and short-term weight loss compared to standard protein diets, but long-term efficacy is comparable to other energy-restricted diets.Good
