The initial weight loss that occurs in the body is the loss of water weight. It happens by restricting calorie consumption but it doesn’t help in building muscle mass or losing body fat.
Carbohydrate consumption is important before lifting and working out. Eating before workout provides the energy required to perform better and work out harder.
While energy comes from Carbohydrates for working out, protein helps building muscles after a workout. Protein is not used as fuel for energy during a workout.
If one is scared about getting sick from eating before a workout, they should start by eating fruits about three hours before a workout. Foods high in fibre, sugar-alcohols, insulin and chicory root are a no-no before the workout session.
