4. Energy bars
Remember that energy bars are called so simply because they contain plenty of nutrients that are necessary for an athlete before he starts his workout session. Some of the ingredients that you commonly find in energy bars would be sugar, carbs and some certain components that people need when they are physically active. If you consume an energy bar after your training, then the energy that you get from this snack will stimulate fat production. Instead of burning the calories from it you will store them as fat. Another bad news is that energy bars slow down the metabolic processes if they are eaten after exercise.
