Russ, is it possible for you to post a short summary of your findings thus far? I'm having trouble mentally collating the various posts, and integrating them into a clear conclusion. (And I'm not saying the conclusion has to be bold or irrefutable - just clear.)Martial Arts and Philosophy: Beating and Nothingness

It has been known for decades that low-fat, high-carbohydrate diets can increase plasma triglyceride levels, but the mechanism for this effect has been uncertain. Recently, new isotopic and nonisotopic methods have been used to determine in vivo whether low-fat, high-carbohydrate diets increase triglyceride levels by stimulating fatty acid synthesis. The results of a series of studies in lean and obese weight-stable volunteers showed that very-low-fat (10%), high-carbohydrate diets enriched in simple sugars increased the fraction of newly synthesized fatty acids, along with a proportionate increase in the concentration of plasma triglyceride. Furthermore, the concentration of the saturated fatty acid, palmitate, increased and the concentration of the essential polyunsaturated fatty acid, linoleate, decreased in triglyceride and VLDL triglyceride. The magnitude of the increase in triglyceride varied considerably among subjects, was unrelated to sex, body mass index, or insulin levels, and was higher when fatty acid synthesis was constantly elevated rather than having a diurnal variation. It was notable that minimal stimulation of fatty acid synthesis occurred with higher fat diets (>30%) or with 10% fat diets enriched in complex carbohydrate. Public health recommendations to reduce dietary fat must take into account the distinct effects of different types of carbohydrate that may increase plasma triglycerides and fatty acid synthesis in a highly variable manner. The mediators and health consequences of this dietary effect deserve further study.

I also disapprove of his hypothetical graph, even if I'm guilty of doing the same thing. I'd be more comfortable with it if he provided a source for the four-hour lag time between carbohydrate ingestion and palmitic acid synthesis.

The temporal pattern of postprandial lipogenesis was similar in all subjects. [ ... ] Lipogenesis peaked 4.2 h after the meals; lipoprotein-triacylglycerol concentrations peaked sooner, 2.0 h after the meals (P < 0.02).
... palmitic acid is the initial fatty acid produced during lipogenesis; all the longer fatty acids are made of it. I was recommending the papers to which he links in that post more than the post itself.“Most people do not do, but take refuge in theory and talk, thinking that they will become good in this way” -- Aristotle, Nicomachean Ethics, II.4

I try not to get into this, but... at the gym tonight, I saw a guy:
-on a bosu ball, round-side down
-balancing on one leg
-doing bicep curls
If only there were chains hanging from his dumbbells, it would have been a WTF singularity.

I don't know if you still accept random topics of discussion but I have one I'd like to pick your brain about. I've been reading the tmuscle forum, and it seems like the new hip thing is getting rid of the old, time-tested, post-workout shake, and instead move it to before and during the workout.
Of course, the only people that know about this phenomenon are at the tmuscle and they just so happen to have a series of products designed for this (that costs $250/month!). Are these people really full of **** or on to something?

My sentiments on pre-workout carbs are over here. As far as I'm concerned, the whole thing stinks to high heaven.
My question for you is this, though:
-Glucose should be less than four bucks a pound.
-Fancy-ass hydrolyzed whey is maybe eighteen bucks a pound.
-Creatine is eight or nine bucks a pound.
Where the Hell does the rest of your $250 go? Are they crushing up diamonds and having you snort 'em?

This should surprise absolutely no one, but today I tried mixing whipping cream with chocolate-flavoured milk protein isolate for a pre-bed shake, and it tasted a lot better than the olive oil/flaxseed oil blend. I think I'm going to stick to getting my flaxseed oil from milled flax.

Detest flax oil. Milled flax seeds have a lot of advantages, but I really don't like the texture much in shakes. Here's a classic pre-bed thing I picked up somewhere: no fat cottage cheese + bit peanut/almond butter + milled flax seeds + chocolate protein power.
