Macro partitioning

High carbohydrate intake is associated with increased total mortality, while high intake of total fat and individual types of fat is associated with reduced total mortality.

Focus on the quality of your macronutrients. Instead of strictly limiting fat, ensure your fats come from unsaturated sources (like oils, nuts, fish) and moderate your carbohydrate intake, particularly refined carbs, as high carbohydrate intake has been linked to higher mortality in large global studies.
