Lean Machine, created by beverage company Vampt, contains 7 vitamins, 7 grams of protein and 77 calories per serving -- plus 0.5 percent alcohol by volume. While the idea of gym hangovers sound awful, a study published in last December's International Journal of Sports Nutrition and Exercise Metabolism found that alcohol's dehydrating effect can be lowered by toying with electrolyte content. When the ABV was lowered to 2.3 percent and salt was added, beer was shown to hydrate a sample of athletes better than traditional ale. The naturally occurring nutrients found in beer's barley, hops and yeast are also an added plus not found in your average Gatorade.

"We just thought that maybe we could do something that would support a drinker, make it still socially fun, and help them accomplish what needs to be accomplished after an aggressive workout," says Vampt founder Ian Toews.

However, don't get too excited -- Lean Machine is not for sale to the general public yet. When it is ready, it will be sold in slim, 12 ounce cans. Still, we can't help but be wary of what 0.5 percent beer tastes like.
