Macro partitioning
In Korean adults, adherence to a low-carbohydrate diet (LCD) is associated with higher odds of metabolic syndrome, primarily because LCDs in this population often substitute refined carbohydrates with processed meats and animal fats rather than healthy unsaturated fats.
If you are Korean or have an East Asian metabolic profile, simply reducing carbohydrates may not lower your metabolic syndrome risk and could potentially increase it if you replace rice with processed meats or unhealthy fats. Focus on the quality of your diet—choosing whole grains, unsaturated fats, and lean proteins—rather than just cutting carbs.
In adjusted logistic models, adults in the LCD 3 had 15–20% higher odds of MetS... In the Korean context, low-carbohydrate diets commonly substitute rice with processed meats, barbeque-style dishes, or animal-fat–rich meals... This quality gap likely contributes to the adverse associations observed.
Why this rating
Cross-sectional observational study using national survey data; establishes association but not causality.

- 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
