US EditionEating minimally processed meals doubles weight loss even when ultraprocessed foods are healthy, study finds
- A clinical trial conducted by University College London and published on August 4, 2025, showed that 55 adults on a diet featuring minimally processed foods lost double the amount of weight compared to those consuming diets high in ultra-processed foods.
- The trial addressed gaps in UK dietary recommendations, highlighting that ultra-processed foods provide over half of daily calories and dominate many diets.
- Participants followed each diet for eight weeks with a four-week break, losing 2.06% weight on the minimally processed diet and 1.05% on the ultra-processed diet.
- The minimally processed diet produced an estimated calorie deficit of about 290 kcal daily, reduced fat mass and cravings, while the ultra-processed diet had a 120 kcal deficit with no fat loss.
- Researchers concluded that improving access to healthier foods aligned with dietary guidelines is needed, since completely avoiding ultra-processed foods is unrealistic for most people.
