The Claim
In overweight and obese adults on an energy-restricted diet, replacing ultra-processed foods with minimally processed foods is associated with a 2.7% greater reduction in body fat percentage and a 3.9% greater reduction in trunk fat over six months, independent of total energy intake.
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.
Among overweight and obese adults eating fewer calories, swapping ultra-processed foods for minimally processed foods results in a 2.7% greater decrease in body fat percentage and a 3.9% greater decrease in trunk fat over six months, even when total calorie intake is held constant.
See the scientific wording
In overweight and obese adults on an energy-restricted diet, replacing ultra-processed foods with minimally processed foods was associated with a 2.7% greater reduction in body fat percentage and a 3.9% greater reduction in trunk fat over six months, independent of total energy intake, suggesting that food processing level may influence fat distribution beyond overall weight loss.
When people eat whole foods instead of processed ones, their gut bacteria change in a way that reduces how much energy they pull from food and lowers insulin spikes after meals. Lower insulin means fat cells stop storing fat and start releasing it, especially around the belly, leading to more fat loss even when calorie intake stays the same.
What the research says
1 studyWhen people on a diet swap junk food for whole foods, even without eating fewer calories, they lose more fat—especially around the belly—according to this study.
