Most individuals who have tried to lose weight have probably heard about the energy balance equation in some form or fashion. The basic idea behind this equation is that our body weight depends upon the balance between the calories we consume through the foods/beverages we eat and drink and the calories we expend through physical activity and normal daily functioning (breathing, heart beating, etc.). Following this equation, if an individual wants to lose weight they need to tip the balance so that more calories are expended than consumed.
