Ultra-Processed Foods, Energy Balance, and the New US Dietary Guidelines
NIH researcher Dr. Kevin Hall explains what controlled feeding studies reveal about why people eat 500+ more calories per day on ultra-processed diets, and why the 2025 US Dietary Guidelines avoided using the term 'ultra-processed.'

Canon
•
Hall: the metabolic ward studies demonstrate that people eat what's available. When the environment offers ultra-processed food, consumption rises automatically. The solution is environmental design, not individual discipline.
Highlights
•
Ultra-processed diets cause overeating of 500 cal/day — even when matched for macros and palatability
Hall: in a rigorous crossover trial, participants ate 508 more calories per day on an ultra-processed diet compared to an unprocessed diet, even when both were matched for calories offered, macronutrients, sugar, fat, sodium, and fiber. The processing itself drives overeating.Was this useful?
