"We compared how participants fared while eating their habitual diets with how they responded to the two diets that were low in ultraprocessed foods. During the periods when participants ate fewer ultraprocessed foods, they naturally consumed fewer calories and lost weight, including total and abdominal body fat. Beyond weight loss, they also showed meaningful improvements in insulin sensitivity, healthier cholesterol levels, fewer signs of inflammation, and favorable changes in hormones that help regulate appetite and metabolism."
"Ultraprocessed foods make up more than half the calories consumed by most US adults. Although these foods are convenient and widely available, studies that track people's diets over time increasingly link them with obesity and age-related chronic diseases such as Type 2 diabetes and heart disease. With older adults making up a growing share of the global population, strategies that preserve metabolic health could support healthy aging."
Reducing ultraprocessed food intake led to lower calorie consumption and weight loss, including reductions in total and abdominal fat. Improvements occurred in insulin sensitivity, cholesterol profiles, inflammatory markers, and hormones that regulate appetite and metabolism. Comparable benefits emerged whether diets were meat-based or vegetarian. Ultraprocessed foods account for more than half of calories for most US adults and are increasingly linked to obesity, Type 2 diabetes, and heart disease. With an aging global population, preserving metabolic health supports mobility, independence, and quality of life. The findings come from a small sample, leaving uncertainty about long-term persistence and generalizability.
