This is a clip from the article: Notice this part says fruit juice's and sugar.
"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."
Then Mercola goes on in his comments about the Peak fitness program he is selling saying it will produce more HGH than the exercise they talk about in the article (which is eccentric (negative) resistance training, which capitalizes on the fact that the human body can support and lower weights that are too heavy to lift.)
He says: Two Foods You Should Never Eat After Peak 8 Exercises
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.
So he is talking about Peak 8 technique only...the title is very misleading and some parts of the article are confusing...
