Energy balance

High dietary fat intake promotes obesity primarily by increasing energy density and promoting passive overconsumption, while failing to stimulate compensatory fat oxidation, leading to positive energy balance in sedentary individuals.

Focus on reducing the energy density of your diet rather than just cutting fat percentages. High-fat foods are often high-calorie and low-satiety, leading to passive overconsumption. To manage weight, prioritize foods with lower energy density (high water/fiber) and ensure you are not in a caloric surplus, as your body does not efficiently burn off excess dietary fat.

GoodSupportsHIGH confidence
Dietary fat increases the energy density of foods. Abundant evidence from preclinical and clinical studies indicates that fat promotes excess energy intake and positive energy balance. Dietary fat does not promote its own oxidation in the body and is stored efficiently, promoting a positive fat balance.
