If you have diabetes — or even insulin resistance, which is a sign that you are on the way to having diabetes — you’ve probably been told to exercise to improve your health.

And, of course, you know that what you eat is important, too. But what may come as news to you is that what you eat after exercise matters — a lot.

That was the intriguing conclusion of investigators at the University of Michigan at Ann Arbor. I called senior author Jeffrey F. Horowitz, PhD, for details.

EAT TO IMPROVE INSULIN SENSITIVITY

In this study measuring the effect of exercise and post-exercise meals on insulin sensitivity, Dr. Horowitz and his team asked nine healthy, sedentary, non-obese men to each participate in four separate experimental trials on different days.

During three of these trials, the subjects exercised on a treadmill and stationary bicycle for 90 minutes, then ate different types of meals throughout that day, as follows:

Daily meals were calibrated to replace the calories and the nutrients expended during exercise.

Daily meals replaced the calories expended during exercise and were low in carbohydrates (about half the carb level of the other meals in the study).

Daily meals replaced the carbohydrates expended during exercise and were lower in calories (about 25% less than the other meals).

The subjects also participated in a non-exercise “control” trial where they simply ate meals to replace their daily calorie expenditure.

The morning after each session (22 hours after the last meal), researchers tested each subject’s metabolic activities, including a blood test for insulin sensitivity.

They found that all three exercise sessions improved insulin sensitivity, but the effect was most pronounced when the men had eaten lower-carbohydrate meals after exercise.

These results were published in the December 31, 2009, issue of the Journal of Applied Physiology.

FEWER CARBS = BETTER METABOLISM

Eating different types of food after exercise produces different effects on the body’s metabolism, Dr. Horowitz explains, noting that even modest cutbacks in carbs helps.

To apply these findings, there’s no need to go to extremes — bu

This is only part of the story — for fitness and weight loss, regular, consistent exercise is, of course, also a must.

Dr. Horowitz and his team are now working with obese individuals to identify the minimum level of exercise that will improve insulin sensitivity that extends into the next day.

But for now I would be just as proud to call you my daughter. I never had children but you are one any parent would be proud of.

The amount of outside money and right wing idiots though don’t give me much hope for our future. Same for those of you who think it’s funny to see education take a hit.

My brother is leaving teaching as it is now becoming a mcjob. You can keep quoting statistics but what this will lead to is poorer education. But then most of the proWalker camp are either wealthy or undereduated anyways.

The private sector unions have been in retreat since Regan broke the air traffic controllers. With Big Business making record profits they are still trying to bust or neutralize unions so they don’t have to share.

It is just more proof that we need to help folks make more accross the board not make them accept less so a few can get filty rich at thier expense.
