Macro partitioning
A low-carbohydrate diet is associated with greater reductions in triglycerides and VLDL cholesterol in the first 6 months compared to a low-fat diet, but these differences diminish by 2 years.
If you start a low-carb diet, you may see a quick improvement in triglycerides and VLDL cholesterol within the first 6 months. However, as you gradually increase carbohydrates over the year, this specific benefit may fade. It is still a positive early marker, but not a permanent differentiator from low-fat diets.

During the first 6 months, the low-carbohydrate diet group had greater reductions in... triglyceride levels, and very-low-density lipoprotein cholesterol levels... than did the low-fat diet group.
Why this rating
RCT, clear statistical significance for early time points.

- When combined with comprehensive behavioral treatment, low-carbohydrate and low-fat diets produce equivalent long-term weight loss (approx. 7% at 2 years), refuting the claim that low-carb diets are superior for long-term weight loss.Strong
- A low-carbohydrate diet produces significantly greater improvements in HDL cholesterol levels compared to a low-fat diet, even when weight loss is equivalent.Strong

- 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
