The Claim

In obese adults undergoing energy restriction, a 12-month intervention to restrict ultra-processed foods reduced the NOVA-UPF score from 2.74 to 1.86, while the control group showed no significant change (2.62 to 2.47), indicating that targeted dietary guidance can modestly reduce ultra-processed food consumption even in populations with initially low intake.

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.

Cause and effect

In plain English

Among obese adults on a calorie-restricted diet, a 12-month program that limited ultra-processed foods lowered their ultra-processed food consumption score from 2.74 to 1.86, while those without the program showed no significant change.

Why this might work

When people are given clear instructions to avoid ultra-processed foods, their brain strengthens its ability to resist cravings for these foods, leading them to choose simpler, less processed options even when calories are restricted.

  1. Study: Effectiveness and metabolic impacts of restricting the consumption of ultra-processed foods in individuals with obesity submitted to energy restriction: a randomized clinical trial.

    When obese people were told specifically to avoid ultra-processed foods while eating fewer calories, they ate even less of those foods than people who just ate fewer calories without special advice. This shows that clear guidance helps, even if people weren’t eating much junk food to begin with.
