I just read through 4 articles on the subject and it actually didn't mention that. It just stated more or less that they want people to take it for weight loss and as a metobolic booster, also as a fat burner. On their web site they have an email address you may want to email them before hand.

Here is the email address if you would like to ask them:
pentabo1~mail.silcom.com

This is what it states if he is already in good shape:
But to enhance performance—if you’re really in shape and not overly fat—you may need to actually eat a fair amount more good quality (healthy) fat than most of us. Fat has become your primary fuel source for energy while exercising and if your body fat isn’t elevated, you may find that you "run out of gas" on this product. Just remember that on a low carbohydrate diet, the "gas" you’re running on is dietary fat and body fat. With that in mind, you’ll want to follow the lead of the triathlete training camps and fat load before endurance events—guacamole, olives, cheeses, meats. You may even want to eat some fat during the event. A good source, easily portable for the athlete, is macadamia nuts, a source with plenty of fat calories to sustain you, and not many carbs to get in the way of effective fat burning. That way, you can get a boost from Pentabosol.

Hope this helps.
