Metabolic Rate
Metabolic rate is the rate at which your body burns calories during your day to day life. Whereas BMR is at a state of total rest, metabolic rate takes into account daily life, and the calories expended during the day. Metabolic rate is affected by many factors such as age, sex, activity levels, muscle mass, disease and weight.
Athletes can often have a huge metabolic rate, despite being relatively small in stature, due to their intense training and competition schedule. Many athletes consume around 7000 calories per day- almost three times the amount a normal male would consume.
