Fats vs. Carbs

[synthetic]

Could have sworn this was bodybuilding.com and not checkoutmyenduranceandstickyourhandupmybutt.com

put it this way... what are you 'building' your body for? Personally im not for prancing around on stage in a bikini in front of other men. On the other end, I have a significant other, so there is no need to go to a club to show off my body because I am lacking personality to attract a female.

Yes professional body builders do what they do to: "prance around on stage in a bikini in front of other men"...

I understand you may have ideological differences when it comes to body building, but I can assure you few are pursuing this for the scenario you described above ^ Personally I do see functional strength/endurance/speed as some of the many pros of body building but for me and I'm sure many others it's much deeper. It's chronic goal setting and achieving, hard work, which pays dividends. Makes us feel, look and thus do better. I could elaborate further but I'm sure you get the gist of it.

You saying you have a personality?

Sailingpiece, lipolysis is not a rate-limiting process to fat oxidation. This has been seen in controlled iconditions using athletic adults, so your correlational infants-under-infusion study doesn't do much. I think you're still stuck in the old thinking of ↑insulin = ↓lipolysis = ↑fat storage. This model is outated, incomplete, and devoid of context (which is everything). If, as you assert, a more insulinogenic environment would lead to "an increased proportion of fat mass" regardless of the chronically sustained net caloric balance, then how would you explain the multiple controlled studies in human adults comparing diets of diffferent insulinogenic capacities yielding no significant difference in body composition? It's easy to assume & make claims, but you'd have to put up better evidence to substantiate these claims.

Yes I agree that the study I presented does not illustrate how the body handles various substrates, particularly FFAs...But I'm pretty sure that insulin and glucagon levels are the single most important factor that determines how the body will store or mobilize its fuel sources(1,2).

I don't see why ↑insulin = ↓lipolysis = ↑fat storage isn't a valid conclusion, or close to a complete model given the idea that increased insulin decreases mobilization of FFAs, thereby forcing the muscle to use its glycogen(3). If you are to ingest lipids during this hormonal state AND are in a calorie surplus, fat storage is inevitable !

PS: any way you can refer me to the studies that you mentioned ?

I'm sure Alan will have another educational response for ya bro, but I'm a kind of guy who goes cross-eyed even just reading such things, i don't even know half of those words you typed My ESL grades were **** man. But you do know that insulin spikes are irrelevant, right? Who cares?

Good post. On spread. =)

What "words" in post are unclear brotha ? ....perhaps insulin spikes are irrelevant, but my concern here is the mechanism behind a net increase in adipose tissue.

I have droned on ad nauseam about this in the past, I'm sure you could search up a ton of info on this board (& off). Thankfully for you & others, James Krieger has written a nice gob of enlightening material on insulin that's freely available. Here, please read it carefully (here's the 1st of a multi-part series):
