Doctor warns that eating too fast is linked to three conditions
“Actually, it does,” Dr. Sarah Berry answers on the ZOE Science & Nutrition Podcast.
“There’s a lot more to the rate of eating than how it interacts with our weight.”
Talking to host Jonathan Wolf, Dr Berry cautioned that eating too fast “isn’t good for us”.
Dr Berry explained: “Essentially, your brain needs time to realize that it is full.
“And studies have shown that it takes your brain five or as long as 20 minutes for your stomach to catch up.

“And research also tells us that eating slowly increases the response of appetite-regulating hormones.”
Not only is too fast linked to obesity and thus, disease – such as type 2 diabetes – it is linked to excess visceral fat.
Dr Berry explained that it is “a type of fat that sits inside the walls of your abdomen and surrounds all your organs”.
Having excess visceral fat is associated with poor cardiometabolic health.
Dr Berry cited a 2017 study, authored by a cardiologist at Hiroshima University in Japan, which found “fast eaters were almost twice as likely to develop metabolic syndrome”.
Fast eating was linked with greater weight gain, higher blood sugar, higher cholesterol and larger waistlines.
Dr Berry said: “There has also been other research published which has drawn a link between fast eating and a higher risk of type two diabetes.
“And studies have shown that this may be because chewing more slowly stimulates greater insulin release, which means better glucose control.
“And we think it may be because if you chew for longer, you have more saliva, and that leads to an earlier insulin and glucose release.”
Fast eaters have also reported poor digestion and acid reflux, but Dr. Berry pointed out that all the research has been observational.
“But the one who does gives us [is] Kind of the first clue that something interesting is going on.”
Here are three health conditions eating too fast puts you at risk for:
- diabetes type 2
- metabolic syndrome.
