was: Re: More on Fructose Post Workout (Tim Wilbur)

Firstly, as Tim has already cautioned, with the material AST

presents, as it is usually presented with the purposes of selling

their products, whether directly or not. The sine qua non of

manipulating fructose to sucrose ratios to favor a higher glucose to

other sugar ratio (since a sucrose molecule is equal parts glucose

and fructose).

For my post-workout shake, I refuse to settle for 2nd best, i.e.

corporate produced sports drinks and juices with sugar ratios that

are only close to optimal. Looking carefully at the ingredients of a

typical Powerade, the main ingredients are typically high fructose

corn syrup followed by maltodextrin (glucose polymers), although the

dextrose equivalency of the maltodextrin is not stated (despite its

obvious importance). My personal carb of choice is a mixture of

glucose (dextrose) and maltodextrin (with a dextrose equivalency of

18). My protein of choice is a mix that I blend myself, composing of

whey hydrosylates, whey isolates, whey concentrate, egg protein, and

amino acids. It's the most important meal of the day, why debate

whether there is an alternative or whether something else is just as

good?

Rosemary is right (in a Fruits & nutrition reply post), in that the

physique community is countless steps ahead of research papers,

physicians, dieticians, and any other " authority " on nutrition. The

reason is quite simple. As we are preparing for our bodybuilding

competitions (natural bodybuilders especially, because they have to

pay extra careful attention to nutrition and training as compared to

their juiced up counterparts), we need to bring our bodyfat levels

to subhuman standards, typically 2-4%. In addition, we need to drop

a lot of water. If we make a mistake anywhere along the hierarchy of

dieting, our conditioning will be less than perfect and this has a

direct effect on how well we perform in competitions. Ask any

competitive bodybuilder, we don't waste our time debating the

usefulness of fruits. Our job is to develop a perfect physique, and

this requires a concerted effort and impeccable nutrition, contrary

to someone who chooses to live a " healthy nutritious lifestyle, "

whatever that is.

Anyone who has prepared for competition will know, that the more

times you go through the contest preparation, the better the

conditioning come contest day. Bodybuilding competitors are living

research papers, except they choose not to invite the scientists

over to verify hypotheses. The nutrition of these bodybuilders is

very predictable, from the very first week the diet starts, the carb

content is gradually decreased, the fat and protein content is

adjusted accordingly, all with considerations of weight and

appearance. Once every 5-7 days the carb content is increased to

prevent backlash, afterwards the gradual reduction continues. There

are no debates about where fruits belong in these diets -- they

don't.

If your goal is to loose fat as quickly as possible, while maintaing

as much muscle as possible, loose the fruits altogether. If you need

a research paper to convince you, I'm sure it'll arrive in several

years or so. Or, you can choose to fix your diets in accord with

what produces the best possible results in the real world, as

opposed to what would make good sense according to a textbook or a

research paper.

Just my 2 cents.
