Weight maintenance and fitness are complicated. Recent studies looking at the effect of marital status on fitness level has shown just how complicated things can get. A study of 8900 adults over several years found that those who were married showed a drop in fitness level based on treadmill tests. Men who became divorced had improved fitness.

Another study of over 6900 men and over 1900 women followed over 3 years found that the women who remained single had an increase in their fitness. The women who married showed no increase in their fitness level. Men who remained single and those who married showed a decrease. Those who divorced during the course of the study gained fitness.

These studies point to the fact that marital status appears to have a significant impact on fitness and health. It seems that both men and women may tend to let themselves go when they are in a secure relationship.

Knowledge is power. Knowing that marriage might lead to a decrease in fitness may change behaviors and help couples to make exercise and healthy eating a priority in their relationships. It is much better to be fun and fit than fat and happy.
