The Claim

Consumption of an ultra-processed diet increases daily carbohydrate intake by approximately 280 kcal and fat intake by approximately 230 kcal, while protein intake remains unchanged, relative to a less processed diet.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Quantitative
1 study reviewed
In plain English

People who eat ultra-processed foods consume about 280 more kilocalories from carbohydrates and 230 more kilocalories from fat each day than those who eat less processed foods, with no change in protein intake.

See the scientific wording

Ultra-processed diets increase daily carbohydrate and fat intake by approximately 280 kcal and 230 kcal, respectively, while protein intake remains unchanged, suggesting a potential role for protein leverage in driving excess energy consumption.

Why this might work

When food has less protein relative to its calories, the body keeps eating until it gets enough protein, which forces it to consume extra carbs and fats. The food is also easy to eat quickly, so people eat more before feeling full.

  1. Study: Ultra-processed diets cause excess calorie intake and weight gain: An inpatient randomized controlled trial of ad libitum food intake

    When people ate ultra-processed foods, they ate about 280 extra calories from carbs and 230 extra from fat each day, but their protein intake didn’t change—suggesting they ate more just to get enough protein, even if they weren’t hungrier.
