Basal Metabolic Rate

• A 30-year-old woman who is 5'6" tall and weighs 120 pounds needs approximately 1,339 calories per day to maintain her weight if she does nothing but stay in bed all day. If she is moderately active and exercises three to four times per week, she would need an additional 700 to 800 calories to maintain her weight; less and she would lose weight. That's why exercise is key to weight loss.
