Fat But Fit? Study Reveals That Fitness, Not Weight, Predicts Risk Of Early Death

When it comes to living a long and healthy life, a meta-analysis of mortality studies finds that being physically active, no matter what your weight, trumps being thin and unfit. Researchers at Middle Tennessee State University, led by exercise scientist Vaughn Barry, Ph.D., examined 10 past studies that recorded information about participants' body mass indexes and fitness levels.

It seems like such a contradiction to be thin and unfit or overweight and fit. You would think that being active would eventually lead to weight loss. I guess that's where those pesky genes and hormones come into the picture! 11-28-2013 5:17pm

Their size and shape is dependent on their genetics.  A Saint Bernard will never be a Chihuahua and both breeds of dog can become overweight if they eat too much and don't move enough.  I would think it would be much easier for the Saint Bernard to become overweight than the Chihuahua or think a Greyhound....they have extremely fast metabolisms. So genetics dictates overall size and shape as well as prevalence of weight gain (or not). 11-29-2013 7:07am
