Calculate your Body Mass Index (BMI) to find out.
Body Mass Index (BMI) is a measure of a person's weight in relation to height, not body composition.
BMI values apply to both men and women, regardless of age or frame size.
Use this information, along with other health indices, to assess your need to adjust your weight.
BMI is a mathematical formula in which a person's body weight in kilograms is divided by the square of his or her height in meters (i.e., wt/(ht)2. The BMI is more highly correlated with body fat than any other indicator of height and weight (NRC p563).
Your BMI results:
< 18.5 indicates underweight
20 > 25 is considered ideal
25 > 29 indicates overweight
> 30, experts consider an indicator of obesity

What a Difference
60 Minutes Can Make
It’s just an hour. At 2 a.m. on March 14, time changes as we “spring forward” one hour overnight. It wouldn’t seem to be that big of a deal, but it is according to researchers at the University of Michigan’s Center for Sleep Science. They have found that in the days immediately following the spring time change each year more people have serious car accidents, most likely due to the sleep loss and adjustments that our biological clocks must make to the new schedule.
To prepare for the time change, start going to bed and waking up 15 minutes earlier each day between now and the start of Daylight Savings Time. This helps reset your biological clock.
The spring time change isn’t the only time we should be concerned about our levels of sleep. According to the sleep researchers, adults ought to get 8 to 8.5 hours of sleep every night, but few of us do. This does more than leave us groggy in the mornings. Findings have shown that a lack of sleep may increase risks of obesity, diabetes, stroke and heart attacks.
