Energy balance

Consumption of ultra-processed foods (UPFs) causes increased energy intake and weight gain compared to whole foods, independent of matched macronutrients.

Prioritize whole, minimally processed foods. Even if you match the calories and macros, ultra-processed foods are engineered to override your body's natural fullness signals, leading you to eat significantly more and gain weight.

GoodSupportsHIGH confidence
In a single mechanistic study, consumption of UPFs led to increased energy intake and weight gain relative to whole foods.
