Stay active, not just thin, to live longer.as we hone our understanding of the roles diet and exercise play in maintaining health, it's important to distinguish being thin from being fit. Fitness does not protect you from being overweight Overweight Refers to an investment position that is larger than the generally accepted benchmark. Notes: For example, if a company normally holds a portfolio whose weighting of cash is 10%, and then increases cash holdings to 15%, the portfolio would have an overweight , and a normal weight does not protect you from being unfit unfit not properly prepared, e.g. physically incapable of performing hard work as in racing, because of lack of training. Said also of food prepared unhygienically. unfit for human consumption . The long-running Lipid lipid Any of a diverse class of organic compounds, found in all living things, that are greasy and insoluble in water. One of the three large classes of substances in foods and living cells, lipids contain more than twice as much energy (calories) per unit of weight as the Research Clinics Study has drawn out a relationship between increased mortality risk and being unfit, regardless of whether you're overweight. A similar association with increased mortality risk was found among the fit-yet-overweight. Being fit mitigated many of the effects of overweight, but not all. It's important, then, to strive for thinness and fitness. In the 1970s, over 5,000 participants (divided more or less evenly by gender), average age 47, were given a treadmill test treadmill test Exercise stress test, see there to determine fitness, and they had body mass index calculated. Researchers followed up annually to assess vital status through 1998. The subjects' increased risk of death, as compared to the "fit-not fat" groups of both genders, were as follows:
Women Men
Fit-not fat 0% 0%
Unfit-not fat 30% 25%
Fit-fat 32% 44%
Unfit-fat 57% 49%
This means that being either overweight or unfit increases the risk of death by approximately 30%. Taken together, these factors increase the risk by nearly 50% for men--and women are even more at risk. Merely cutting calories to shed those extra pounds will do wonders for your self-image, but it won't make you as healthy as the person who cuts calories and stays active.
