Macro partitioning
A high-monounsaturated-fat diet improves insulin sensitivity compared to a high-saturated-fat diet, but this benefit disappears if total fat intake exceeds 38% of total energy.
Choose monounsaturated fats (like olive oil, nuts) over saturated fats to improve insulin sensitivity. However, keep your total fat intake moderate (under 38% of calories). If you eat too much fat, even healthy fat, you lose this benefit.
ModerateConditionalMEDIUM confidence
a high monounsaturated fat diet significantly improves insulin sensitivity compared to a high-saturated-fat diet. However this beneficial effect of monounsaturated fat disappears in individuals whose total fat intake exceeds 38 % of total energy
Why this rating
Based on a specific multicentre intervention study (Vessby et al. 1999) cited by authors.

- Weight reduction of 5-10% is the primary and most powerful dietary intervention for treating metabolic syndrome, as it significantly improves insulin sensitivity and corrects associated metabolic abnormalities.Good
- High-glycemic-index (GI) carbohydrate foods worsen metabolic syndrome factors (glucose, triglycerides, HDL, fibrinolysis), whereas high-fiber, low-GI foods do not induce these detrimental effects.Good

- 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
