A recent study of 26 healthy men highlights the amazing benefits – even in a brief time period – of regular exercise. Several previous studies have shown unhealthy changes in blood sugar control as well as genetic changes to fat cells in response to overfeeding.
This study compared two groups, both of which were significantly overfed relative to their usual calorie level. Both groups decreased their usual daily activity level during the study, but only one group ran at a moderate pace on a treadmill 45 minutes every day. (This group consumed additional calories to compensate for the additional calorie burn, meaning that both groups were overfed by the same net amount).
In just a week, the non-exercising group showed deteriorating insulin action and negative changes to key genes controlling metabolism. The exercisers showed no significant changes!
If you have trouble getting back on track after the big holiday feed-athons, consider these study results! If you are still feeling off-track from Thanksgiving dinner, this might be the encouragement you need . . . yes, it does matter! What you do NOW always matters. Even with dietary splurges, a little activity goes a long way toward better health. Happy Holidays!
