Scientists have finally proven that ultra-processed junk food causes weight gain - not just raises risks it - according to a new National Institutes of Health (NIH) study، the Daily Mail said.
We've known for decades that people whose diets involve a lot of soda، candy، pizza and chips are more likely to overeat and become overweight.
But despite its small size - consisting of just 20 people - the new study claims to have shown that these foods cause consumers to eat too much and gain weight، while healthier whole foods cause people to shed pounds.
The researchers said they aren't yet sure what it is about processed food that causes over eating and weight gain، but because the two diets they put participants were matched for dietary content، it's clear the key is in processing itself. Lawmakers in some states have tried to ban ultra-processed foods، documentaries have tried to expose their empty calories، and countless studies have linked them to obesity، diabetes، poorer heart health and shorter lifespans.
Ultra-processed foods have long been a prime target of the battle against the obesity epidemic.
But they've never before been proven to actually cause weight gain in and of themselves.
To establish this ground-breaking finding، the National Institute on Diabetes and Digestive and Kidney Diseases (NIDDK) put 10 healthy adult men and 10 health adult women volunteers on tightly controlled diets for a month.
