Macro partitioning
A diet high in fiber and low in glycemic index does not enhance weight loss or fat loss compared to a standard diet when both are in a caloric deficit.
Eating a low-glycemic, high-fiber diet won't help you lose more weight than a standard diet if you are already eating fewer calories. Focus on the total calorie deficit rather than strictly avoiding high-glycemic foods.
GoodRefutesHIGH confidence
A diet with 1400 mg of calcium, increased fiber content, and fewer high-glycemic index foods did not result in greater weight (10.6 +/- 6.8 kg) or fat (8.5 +/- 7.8 kg) loss than the standard diet with 800 mg of calcium.
Why this rating
Randomized controlled trial with 48-week duration and low dropout rate.

- 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
