Macro partitioning
Macronutrient composition (carbohydrate vs fat vs protein ratios) does not significantly impact weight loss outcomes when total caloric intake is controlled, provided the diet is sustainable.
You do not need to follow a specific 'low-carb' or 'low-fat' diet to lose weight. Studies show that when calories are equal, the source of those calories (carbs vs fat vs protein) matters less for weight loss than the total amount. Focus on finding a dietary pattern you enjoy and can stick with long-term.
StrongRefutesVERY_HIGH confidence
A meta-analysis of 48 clinical randomized controlled trials including more than 7000 participants that followed dietary recommendations varying macronutrient distribution under free-living conditions, showed no significant differences in weight loss at 6 and at 12 months and no significant improvements in glycemic control or lipid profile
Why this rating
Based on a meta-analysis of 48 RCTs with >7000 participants.

- Caloric restriction interventions produce significant short-term weight loss but are associated with significant weight regain and increased hunger/appetite over the long term (12+ months).Good
- Combining energy restriction with resistance or mixed exercise training is more effective for reducing body fat and preserving/increasing muscle mass than energy restriction alone.Good
- Physical activity, particularly resistance and mixed exercise, reduces visceral adipose tissue more effectively than caloric restriction alone.Good

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
