Why Dietary Fat Matters
Fat fuels your body, carries vitamins, and supports hormones. Cutting it too low can leave you tired and hungry.
Food and goals turn into simple daily targets you can hit.
Guidelines place fat between 20 and 35 percent of daily calories. The right share depends on your goal and food preferences.
This tool also caps saturated fat, the type best kept under 10 percent of calories.
