Most of the people in magazines and on TV are far slimmer than average, yet this is the “ideal” that many people aim for. Before you decide that you won’t be happy until you get down to a certain number of pounds, consider:
Your age. You probably wish you could get back to your college weight. But normal changes in metabolism and hormone levels that occur with aging can make this more difficult.
Your gender. In general, men have more muscle and heavier bones than women, which means that healthy men usually weigh more than healthy women of the same height.
Your current weight. If you are very heavy, focus on losing a smaller amount (such as 10 percent of your body weight). Losing just 5 to 10 pounds can improve your health.
A pound of muscle weighs the same as a pound of fat, but it takes up less space. Think of a trained athlete and a “couch potato.” Even though they may be the same height and weight, the athlete looks fitter, is healthier, and probably wears a smaller size of clothing. If you are muscular, a body fat test may be a more accurate measure of your ideal weight than the bathroom scale. Talk to your healthcare provider, who can help you set appropriate goals for yourself.
Body mass index (BMI)
Your body mass index is a number calculated from your weight and height. It is a fairly reliable indivactor of body fatness for most people. To calculate your BMI, see this BMI calculator from the CDC: http://www.cdc.gov/healthyweight/assessing/bmi/adult_bmi/english_bmi_calculator/bmi_calculator.html
