Macro partitioning
Recent weight losers (≥10% loss within the past year) achieve weight loss primarily through reduced fat intake and increased physical activity, without necessarily reducing absolute total calorie intake compared to overweight/obese individuals.
If you are recently trying to lose weight, focus on reducing your fat intake and increasing your physical activity. You may not need to drastically cut total calories; simply swapping high-fat foods for lower-fat options and moving more can be effective.
ModerateQualifiesMEDIUM confidence
Recent weight losers did not differ from overweight or obese individuals on absolute calorie intake but reported less fat (79; 95% CI = 75, 83 g vs 84; 95% CI = 82, 86 g; P = .016) and more activity.
Why this rating
Observational data; self-reported dietary intake may have bias, but the sample size is large.

- 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
