My friend told me to start bodybuilding as the more muscle I gain the higher my metabolism would be. He said I would burn more fat and could still eat loads of food?
It has been estimated that one pound of muscle burns 25-50 calories per day and each pound of stored fat only burns 2-3 calories per day. So yes your metabolic rate will increase however, building large muscles takes lots of hard work and dedication and I would not recommend intense training sessions to any inactive individual. To burn off excess fat you should be doing some form of low-intensity high duration aerobic exercise, after the weight has come down and fitness levels improved then bodybuilding may be okay!
