My mom is a fitness and nutrition coach. She says light beer is better for your metabolism than any mixed drink, even a soda water-based one. In her words, "any alcohol slows down your metabolism because your body has to work off the toxin (alcohol) before it can work off carbs and fats." I don't totally understand it, but she's suggested that I stick with light beers. My favorite is Bud Light, but I’ll take Coors Light in a pinch.
