The Claim
Consumption of ultra-processed foods occurs at faster eating rates than consumption of unprocessed foods, and this faster eating rate independently contributes to increased daily energy intake, resulting in an average increase of 814 kcal per day and 1.1 kg of weight gain over one week.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People eat ultra-processed foods faster than unprocessed foods, and this faster eating leads to consuming 814 more calories per day and gaining 1.1 kilograms in one week.
See the scientific wording
Ultra-processed foods are consumed at faster eating rates than unprocessed foods, and this faster consumption independently contributes to higher daily energy intake, with one study showing a 814 kcal/day increase and 1.1 kg weight gain in one week.
Ultra-processed foods are softer and broken down more by industrial processing, so people chew them less and swallow them faster. This speed prevents the stomach and intestines from sending fullness signals to the brain in time, so the person keeps eating more than needed. The extra calories are stored as fat, leading to weight gain.
What the research says
1 studyStudy: Ultra-processed foods and cardiometabolic risk: from evidence to policy
People who eat ultra-processed foods quickly take in way more calories and gain weight faster — even if the food has the same nutrients as healthy food. The study proved this by letting people eat only ultra-processed or only whole foods and watching what happened.
