Two Foods You Should Never, Ever Eat After Exercise

by: Dr. Mercola | July 27 2010

Did you know that what you eat directly after exercising – typically within two hours – can have a significant impact on the health benefits you reap from your exercise?

Consuming sugar within this post-exercise window, will negatively affect both your insulin sensitivity and your human growth hormone (HGH) production.

A recent study in the Journal of Applied Physiology found that eating a low-carbohydrate meal after aerobic exercise enhances your insulin sensitivity. This is highly beneficial, since impaired insulin sensitivity, or insulin resistance, is the underlying cause of type 2 diabetes and a significant risk factor for other chronic diseases, such as heart disease.

In addition, as HGH Magazine explains, consuming fructose, including that from fruit juices, within this two-hour window will decimate your natural HGH production:

“A high sugar meal after working out, or even a recovery drink (containing high sugar) after working out, will stop the benefits of exercise induced HGH. You can work out for hours, then eat a high sugar candy bar or have a high sugar energy drink, and this will shut down the synergistic benefits of HGH.

… If you miss reaching HGH release during working out, you will still receive the calorie burning benefit from the workout. However, you’ll miss the HGH “synergy bonus” of enhanced fat burning for two hours after working out.

This is an extremely important fact to remember if you want to cut body fat and shed a few pounds.

The University of Virginia research team demonstrated that carbohydrates are burned during exercise in direct proportion to the intensity of training. Fat burning is also correlated with intensity. However, the actual fat burning takes place after the workout, during the recovery.

This makes the “Synergy Window,” the 2 hour period after a workout, very important in maximizing HGH, once it’s released during exercise.

If you are middle-age and want all the benefits from exercise induced HGH, then apply this strategy.”
