Lose weight by drinking tequila?? Yes, I can picture your eyes rolling, but hang on. I didn't say lose weight by drinking margaritas. They contain too much sugar. Tequila made from the agave' plant contains something that actually reduces blood glucose levels. A report from 77recipes.com indicates researchers have found natural sugars called agavins in the agave' plant. They're not digestible, so they simply pass through your system without spiking blood sugar levels. The agavins also increase levels of a hormone called GLP-!, which slows the stomach emptying process. The result is you take longer to get hungry. Bottoms up! Who says weight loss can't be fun?
