Energy drinks are designed to provide high glycemic carbohydrates to your muscles when you are in an extreme state. This means they are densely packed with a whole lot of simple and complex carbs, which are very caloric. If you’re trying to loose weight, try replacing your energy drink on training rides with an electrolyte drink (such as a Nuun supplement). Electrolyte drinks include all the necessary stuff to help you recover, but without all the carb-based calories.
Yes, you lose weight when you cut calories, but pounds lost aren’t always fat. Some of your weight loss may also come from muscle tissue. Cyclists that diet often end up thinner, but risk becoming slower and weaker on the bike. As pioneering diet expert Covert Bailey once wrote, “When someone says that they lost 20 pounds, the key question is: 20 pounds of what?” Some dieters can end up having a higher percentage of body fat even as they lose weight. And don’t forget that muscle burns calories. The more muscle volume you have, the more calories your body can burn—even when you’re just lying on the couch.
