Party boy
 

Party boy, are you? If you’re serious about losing weight and getting lean, you’d better start seriously considering the effects of alcohol on the body.

"Alcohol causes fat to be stored instead of being used for energy. Essentially, your body will put a hold on the digestion of any food until the liver can excrete the alcohol,"

Alcohol also hurts you in two other areas: "It's a diuretic, which dehydrates you and reduces energy levels. It also can decrease testosterone in our bodies, which is critical for creating muscle," he adds.

Next time you're planning a guys night, stick to one or two light beers or a hard liquor with a diet soda mixer. A six-pack starts in the kitchen.
