Obese people don’t know when they’re full

Hormones are chemical messengers that control a surprising amount of your body. Some, like the ones that help us grow, take years to complete their job! Others only take a couple of seconds. For example, you know how your heart starts beating fast and you breathe harder when you’re scared? That’s the hormone called “adrenaline” taking effect! Well, there’s also a hormone called “glucagon,” which is linked to feeling full. According to research from Charite-University Medicine, the hormone doesn’t work in obese people!

The researchers used 13 obese subjects, 11 lean participants, and 13 diabetics for the study. When the diabetics and lean subjects were injected with glucagon, they reported feeling much fuller. However, when obese people were injected with the hormone, they didn’t feel much of a difference.

“The findings could influence efforts to develop new treatments for obesity and diabetes,” said Dr. Ayman M. Arafat, the leader of the study. “…this study suggests a treatment involving glucagon may be ineffective in controlling meal size in people who are obese.”

If you’ve just had a big meal and still feel hungry, drink a large glass of water and wait 30 minutes. Even if you are not obese, you might not be as hungry as you think!
