Macro partitioning
Plasma fatty acid levels (specifically C16:0, C20:3 n-6, and C20:5 n-3) are independently associated with obesity risk in ethnic minority populations, whereas dietary fatty acid intake is not a consistent independent predictor.
For individuals in these ethnic groups, monitoring blood lipid profiles (specifically saturated and certain polyunsaturated fatty acids) may be more relevant for assessing obesity risk than tracking dietary fat intake alone. Specific fatty acids like C16:0, C20:3 n-6, and C20:5 n-3 were linked to higher obesity odds.
In this study, PFAs but not DFAs were independently associated with obesity, and different among the four ethnic minorities.
Why this rating
Cross-sectional design limits causal inference; however, the sample size is adequate and statistical adjustments for confounders were made.

- 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
