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.
