In order to lose weight, energy expenditure must exceed energy intake. Negative energy balance occurs when the body is using more energy than it is taking in BMR or basal metabolic rate, is the main component of energy expenditure. This is the number of calories we burn that is needed for basic bodily functions, like pumping blood through our veins entyme production, cell turnover, and breathing but does not Include digestion.
