The calories needed for a woman to maintain her weight is: WBMR = 655 + (4.3 × weight in pounds) + (4.7 × height in inches) − (4.7× age in years) The calories needed for a man to maintain his weight is: MBMR = 66 + (6.3 × weight in pounds) + (12.9 × height in inches) − (6.8 × age in years) A typical chocolate bar will contain around 230 calories.
