Carbs are not the only cause of belly fat, but if you eat a lot of them, they can certainly play a role. "If you eat any type of macronutrient in excess, you will gain weight," said Robert Milanes, MD, founder of Luminary MD in Irvine, CA, told POPSUGAR. Still, the way carbs are digested makes them particularly risky when you're trying to lose weight or prevent weight gain.
"Carbohydrates are broken down into glucose, which can be used as an energy source by our cells, tissues, and organs, "said Aastha Kalra, DO, founder of Weight Zero MD, told POPSUGAR. When eaten in excess, "glucose is stored as glycogen in the liver," Dr. Milanes added, which can be converted back to glucose and used for energy when few or no carbs are consumed
The real trouble begins when even your glycogen stores are at maximum capacity. "When we eat carbs, insulin levels rise," Dr. Kalra said. Insulin is tasked with taking glucose from the bloodstream to areas of the body that need energy, but it's also a fat storage hormone. Dr. Milanes explained that if you eat too many carbs and there are no areas of the body that need energy, the glucose has nowhere to go and will be stored as fat instead
There to eat carbs without gaining weight
There has two types of carbs: simple carbohydrates (found largely in processed foods), which are made of simple sugars and digested by the body quickly, and complex carbs, which are high in fiber and digested more slowly. Comprehensive carbs keep you feeling fuller longer, but they also keep your insulin levels stable, which promotes energy burning and prevents fat storage.
While you can not spot fat from your midsection, eat more complex carbs ̵
