The Claim

Higher consumption of ultra-processed foods is associated with increased risk of obesity and overweight, with each 10% increase in ultra-processed food intake linked to a 9–18% higher odds of weight gain, and daily intake exceeding 50 grams associated with a 34–45% higher risk of overweight and up to a 61% higher risk of abdominal obesity.

In plain English

People who eat more ultra-processed foods have a higher likelihood of gaining weight, becoming overweight, or developing abdominal fat, with the risk increasing as their intake of these foods rises.

See the scientific wording

Higher consumption of ultra-processed foods is consistently associated with increased risk of obesity and overweight, with each 10% increase in ultra-processed food intake linked to a 9–18% higher odds of weight gain, and daily intake exceeding 50 grams associated with a 34–45% higher risk of overweight and up to a 61% higher risk of abdominal obesity.

Why this might work

Eating lots of ultra-processed foods damages the gut lining, letting toxins enter the bloodstream and trigger inflammation. The liver turns excess sugar from these foods into fat, which builds up in the liver and muscles. This fat and the inflammation block insulin from working, so blood sugar stays high and the body stores more fat, especially around the belly.

  1. Study: Ultra-processed foods, lifestyle management, and cardiovascular diseases: A clinical consensus statement of the European Society of Cardiology Council for Cardiology Practice and the European Association of Preventive Cardiology of the European Society of Cardiology.

    People who eat more packaged snacks, sugary drinks, and ready meals tend to gain more weight and have more belly fat, and this study confirms that link with real numbers: every 10% more of these foods raises weight gain risk by 9–18%, and eating over 50 grams a day can boost obesity risk by over 30%.
