http://perfecthealthdiet.com/?p=5498 Paul Jaminet compares PHD to Danny Roddy and compares Glucose, Fructose and Galactose's(dairy) ability to replenish liver glycogen and muscle glycogen. Do you consume an intra or post workout simple carb source and what are your results? And very importantly - what is your 'exercise'? |

It would have been cool if paul actually took the time to read some of peats work and get a better idea of what he actually recommends and why he does. Instead he decided to focus on one very short blog post by danny that doesn't even necessarily provide a whole lot of info and the only references were from random blog commenters. He could have read and critiqued glycemia in context which has 20+ sources and maybe we would have actually learned something... I think paul should do some more research before writing posts like these, he left out a lot of different critical factors that I cover in the comments. Specifically the glucose paradox. |

Well, he misconstrued my point a bit as I was simply stating that at a point of lowest liver glycogen, fructose is most beneficial and that a can of soda (which I would never actually drink) would be harmless if consumed at that point. If one's goal is to halt the secretion of cortisol ASAP upon waking and to ensure that the liver continues to convert T4 to T3 at its usual rate (which I presume to be based on liver glycogen levels) then the best route would be to rapidly replete liver glycogen upon waking. This is what I do. Fructose isn't really needed during exercise because the Cori cycle is sending plenty of lactate to the liver for glycogenesis (probably a fair amount of alanine is making its way there as well due to muscle breakdown). As such, there's no need for further gluconeogenic precursors. I guess all told this piece misses the mark, but I don't have any problem with the composition of PHD; I simply think the fear of fructose is overblown. With many millions of years of exposure to this "poison," it seems we have evolved to take advantage of it. |

As usual, Paul is more patient than I would be. A very classy (and smart) guy! |

@Cliff Ok, am I to understand that if I start with a blank slate tomorrow and I consume sucrose for fuel instead of fats. Lets see, 180grams protein = 720 cals. 40 grams of saturated fat = 360, protein+fat = 1100 rounded calories. So... if I consume aprox 250 grams carbs from sucrose or honey or orange juice (BUT NOT white rice, white potato) for another 1000 calories <---- this will be a positive thing? Ill continue to walk 1hr/day 4/week with 50lb ruck sack. And will continue to weight train 3x/week. IF I am following correctly, the above should have me losing BF while increasing LBM while normalizing or optimally regulating cortisol and a whole host of other things. Ill sacrifice my body for science just to see what happens, but I need Cliffs input. |

My main criteria is how soon I intend to workout again. Most of my exercise is within my aerobic capacity, and unless I'm fully fasted (24+hrs) I don't find myself reaching depletion. My more intense exercise doesn't last long enough for that to be an issue either. Sometimes I feel like eating PWO, though I'm not necessarily going for simple carbs and there doesn't seem to be an obvious pattern as to what my body wants. Whatever I do, I seem to be faster and stronger next time around. |

Whatever happened to blood sugar and hormonal spikes wrecking health? To gluconeogenesis? To muscle fueled by fat? Measuring blood sugar spikes after high GI meals will tell you where you stand. |

IIRC simple honey is 50/50 glucose/fructose. Back in the day, I used to eat a tablespoon or two of honey post-workout because my workouts were long, aggressive, and left me very lightheaded. This was usually Olympic Lifting, followed by 1-2 specifically strength-related movements (i.e. clean and jerks followed by squats, snatches followed by deadlifts). Honey was just about perfect because I could keep a squeeze bottle in my gymbag (without fear of it going bad), it was a whole food, and it seemed to work well. That being said, I don't workout to that extent anymore so I've lost the need for it. And I have been doing too much DeVany reading lately so I avoid any calories for an hour or so after I train. |

I don't understand how a human can consume 1 Pound of Pure Dry Sugar, and only refill liver glycogen 20-60 grams. Hmmmmmm, might have something to do with refilling of muscle glycogen? (and burning of course)<--another reason to eat carbs at bed time, OR faulty study data?. Paul "Muscle glycogen replenishment is maximized with a carbohydrate intake of 100 calories per hour." ok, so 25 grams/hr to replenish muscle glycogen? <-- where is this proved in the studies? I just don't see it. Anyone know HOW they depleted just these guys livers glycogen without taking into consideration all the lactic acid conversion to glucose surely taking place? |
