Did you know that low blood glucose levels can weaken your willpower, but a new study says you may not need to actually eat sugar to control those sweet cravings. If you struggle to resist food temptations, like getting a 2nd piece of cake or blowing off working out —study shows that low blood sugar could be to blame. But could gargling with a sugary beverage trick your mind and body into resisting those unhealthy temptations?
Quite possibly, according to new research published in Psychological Science. Scientists used to think that getting glucose into your body was key to replenishing your energy and self control. In the new study, participants who just rinsed their mouth with sugar-sweetened lemonade had better self-control on a laboratory test than those who gargled with Splenda-sweetened lemonade. The researchers believe that glucose in a drink can trigger taste buds on the tongue, which then signal the motivation centers of the brain. Basically telling your body to pay attention. This reaction, in turn, helps you turn off whatever automatic response you’re facing (i.e see cookie ,eat cookie).
So will glucose mouth wash help you in the real world? It’s hard to tell. The laboratory test was only 3-5 minutes long, which is much different than long-term feats of willpower, like losing weight or quitting smoking. But if you keep your blood sugar levels in check by eating regularly, a quick swish of lemonade when you’re facing down the dessert buffet can’t hurt, right?
