2 foods to avoid eating after a workout

This article was written and posted originally from Dr Mercola:

” 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.”

Two Foods You Should Never Eat After Exercise

It would be best to AVOID all sugar and fruit juice for two hours after your workout, otherwise you will obliterate the growth hormone response and ruin the major benefit of the workout, which is to increase your growth hormone level. Remember that after age 35, your growth hormone levels radically decrease.

The reason why restricting these carbs after exercise works is that they will prevent the production of the hormone somatostatin. One of the primary purposes of this hormone is to inhibit the production of human growth hormone.

Virtually all exercises, certainly nearly all cardio or standard aerobics, fail miserably when it comes to increasing growth hormone. So if you decide to use the only type of exercise that will increase growth hormone, then it would be a shame to make a foolish food choice that would wipe out most of the benefit from doing these amazing types of exercise.

When you break your exercise session into intervals like this — short segments that alternate high intensity with a rest period in-between – you can dramatically improve your cardiovascular fitness and fat-burning capabilities in a fraction of the time.

This makes logical sense when you consider that, historically, long-duration exercise isn’t “natural.” Our ancient ancestors never ran for mile after mile without rest or recovery. Their exercise was primarily hunting — short bursts of exertion, followed by periods of rest.

By exercising in short bursts, followed by periods of recovery, you recreate exactly what your body needs for optimum health, and that includes both the production of growth hormones and the burning of excess body fat.

Please understand that the sugar and juice restriction are really intended for nearly everyone reading this whose primary purpose is to increase human growth hormone naturally, through exercise, to improve their health.

There is a very small group of elite and professional athletes who are actively competing, where increasing growth hormone is not their primary goal. For these athletes, consuming some carbs, preferably dextrose-based, in the recovery period is probably a good idea to improve their recovery time, as they are competing and not so concerned about long-term growth hormone levels.

It is also important to understand that the two hour post workout sugar restriction is for Peak 8 exercises NOT for strength training or, if you chose to, aerobic exercises. Since neither of these exercises increases growth hormone, there is not an issue with the sugar restriction within the bounds of replacing needs generated from the exercise.”

Bottom line:  If you are doing high intensity interval training and want to increase your HGH, avoid sugar and fruit juice after a workout.

If  you do not know what type of training is appropriate for you, schedule an appointment either in person or on the phone with JJ Flizanes of Invisible Fitness to evaluate your goals, your current fitness level and the plan that is right for you.

    Hi JJ,
    I hope that your setbacks have disappeared and your new book will be out soon. This economy is messing up many things. JJ, I did the 6 week Beach Body program in winter, 2010. I’d been diagnosed with fibromyalgia and had adrenal fatigue. This fall I had a blood test for food sensitivities (like allergies but they can take longer to manifest) and 53 showed up, including whey. So I’m getting smaller by avoiding those foods and taking a test like that may help others. I am also writing because there was an email chain during class about how to cut the sweetness of too-sweet protein powders (like Jay Robb).I signed in but could not find the email exchanges. Is there a way I can search the Beach Body site to find that? I’m using a rice protein now and it’s so sweet that I have a hard time finishing it. Thank you for your help, Kathy

    Hi Kathy

    I am so sorry this took me so long to reply. I wrote and launched Fit 2 Love in February of this year and my Knack Ab book will be in book stores in August 2011. Cutting the sweetness in the shakes can be done by adding some fruit or even vegetables- I have used pumpkin in my vanilla shakes to make a pumpkin pie shake and it was awesome! Some people suggest frozen broccoli- I have tried that too and liked it very much. Just pay attention to your digestion when you do the broccoli- I have been told to only do veggies OR fruit, do not combine. Hope that helps!!!
