flag Cutting ultraprocessed foods to under 15% of calories improved metabolic health in older adults, even without intentional weight loss.

flag A new study finds that older adults can significantly improve metabolic health by cutting ultraprocessed foods to less than 15% of daily calories, even without calorie restriction or weight loss. flag In a trial of 43 adults aged 65 and older, both a lean meat-based and vegetarian diet led to better insulin sensitivity, healthier cholesterol, reduced inflammation, and lower abdominal fat over eight-week periods. flag Participants naturally ate fewer calories and lost weight while following meals aligned with federal dietary guidelines. flag The results, the first to show such benefits from realistic dietary changes outside a lab, support the new 2025–2030 Dietary Guidelines’ recommendation to limit ultraprocessed foods, which typically make up over half of American diets. flag While the study did not assess long-term disease prevention, it highlights a promising strategy for healthier aging. flag Larger, longer-term research is needed.
