I really dont look at exercise as a way to lose weight. Definitiely it can help but the bottom line for weight loss is really restricting the amount of calories one takes in. But the reality of exercise are the benefits one gets with it especially if done regularly.
I do exercise daily by jogging solely to maintain my weight to a normal level for my height because of my risk to develop diabetes due to a strong family history.
Recently in a report from the American Diabetes Association as reported in Medscape Endocrinology June 26, 2010 is a good study that looked at the effect of exercise in preventing diabetes:
Obese boys who engaged in regular aerobic or resistance exercise — without dietary changes — had significant improvements over 3 months in their total body fat, visceral adipose tissue concentrations, and insulin sensitivity than their more sluggish counterparts.
The results were independent of the type of exercise assigned, and suggest that a moderate increase in activity (180 minutes per week) can help prevent type 2 diabetes mellitus in this high-risk population.
In the study, whether aerobic or resistance training did not matter. The insulin sensitivity analysis was the same in both groups although better with the resistance training group.
Plus… this study only looked at the effect of exercise and risk for diabetes without restricting calorie intake. Suggesting that exercise indeed can have tremendous benefical effects in preventing one from developing chronic medical metabolic conditions that can have long term complications.
There you go guys… another good reason to get going…grab your shoes and start running!
