- Weight Loss and the Differences Between Men and Women

- ------------------------------------------------------------------------------

- QUESTION: When I checked the amount of calories that men and women lose when
- exercising, I found some numbers that puzzle me. Even when both the man and
- the woman weigh the same amount, the man loses weight faster, because he burns
- more calories for each hour of activity. It isn't fair! Beside that I don't
- understand why this is true? Could you please shed some light on this
- situation. I would be most grateful.

- ANSWER: Your calorie scale is correct even if it is unusual for most tables
- used in calculating caloric burn and weight loss to indicate the differences
- between men and women. Men and women have different metabolic rates, even
- when their ages, weights, and activities are the same, and it runs about 10
- percent less for women than men. That means that an average sized woman in
- her thirties who lives a life style that is fairly active will burn about 2400
- calories a day. An average man, with a similar build and life style, can use
- about 3000 calories per day. And this difference is also reflected in the
- calculations that can be made for the various intensities of exercise
- programs. In every case, when using total body weights as the unit in
- figuring caloric burn, the woman is at a disadvantage. The basis of this
- difference lies in the proportion of muscle that is included in the total
- weight of the individual. A man's body is made up of about 45 percent muscle
- tissue, compared to only 36 percent for a woman. There are many factors that
- might change the exact percentages but these are close enough for this
- explanation. The simple fact is that it is our muscles that use the greatest
- amount of the body's energy, so that the more muscle mass present, the greater
- are the number of calories that are burned. For some scientific analysis, a
- researcher may choose to calculate the lean mass of the body when calculating
- the amount of energy used, which can overcome this anatomical difference.
- Since you must burn about 3000-3500 calories more than you eat to lose a pound
- of weight, the scientific method doesn't actually help when you are checking
- the scales. However, adding some muscle building exercises to a pure aerobic
- program will add more muscle mass to your frame, and eventually burn more
- calories for you.
