Macro partitioning
The cardiovascular benefits of low-carbohydrate diets depend on the quality of macronutrients used to replace carbohydrates, not the degree of restriction itself.
If you reduce carbs, ensure you replace them with healthy foods like fiber-rich grains or unsaturated fats, not saturated fats. Simply cutting carbs without considering food quality does not improve heart health.
GoodQualifiesHIGH confidence
Meta-analyses suggest that the degree of carbohydrate restriction alone does not yield additional cardiovascular benefits, with outcomes depending largely on the quality of macronutrient substitutions.
Why this rating
Based on meta-analyses of multiple RCTs cited in the review.

- Reducing total caloric intake by 500-1,000 kcal daily (Low-Calorie Diet) is a safe, practical, and effective primary strategy for obesity management, yielding 0.5-1.0 kg weight loss per week.Good
- Intermittent Fasting (IF) produces weight loss comparable to continuous caloric restriction, but is generally not recommended for Type 2 Diabetes patients due to hypoglycemia risk.Moderate
- Structured calorie-restricted diets (800-1,800 kcal) can induce diabetes remission in obese Korean adults with early-onset Type 2 Diabetes, with remission rates up to 75%.Moderate

- 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
