(KAIT/NBC) - No matter how many "no calorie - no sugar" labels there are, you could gain weight when drinking diet soda.
According to doctors, sweeteners in diet sodas could be tricking your body into weight gain.
Whether you drink regular or diet soda, Dr. John Higgins of UT Health says it makes your insulin spike.
When your body makes too much insulin, it will stop burning fat until you lower your insulin levels.
"It has to do with the aftertaste and after effects of the diet soda. It gives them a temporary fill but it actually affects their insulin and other systems and they actually get hungrier later," Dr. Higgins says.
He also says one or two occasionally are harmless, but five or more each day could hurt your heart.
