Could someone please explain the preoccupation Paleos have with exercising in a fasted state? This has come up again and again on comments and I don't understand the benefit.
i myself used to lift heavy in a fasted state. I no longer do as i finally drilled it into my head that getting stronger was my real goal, and not leaning out.
I suppose the fascination with training fasted is just cuz something like 90% of people wish they had a leaner bodycomp than they currently do, and the LG site got mentioned a lot early on in the paleo growth sport and its stuck around.
I do believe in LG's efficacy, its just that i've finally realized that you can't have your cake and eat it, too. Either you work to get stronger in a progression with heavier and heavier iron, which is AIDED by eating pre and post workout, or you work to lose bodyfat and decide that you will NOT get stronger progressively with the iron. In the latter, going in fasted to lift weights that you ALREADY KNOW you can handle will indeed prolly burn off more bodyfat.
Exercising lowers your blood sugar, prompting the creation of blood sugar from stored fat via gluconeogenesis, so long as it can't draw glucose from what you've recently eaten. Making sure that your body is able to do this well, as opposed to never doing this by eating a high carb, insulin triggering diet, may increase your satiety between meals. This is also the only direct way to "burn fat" that exists.
I just cannot train as intensely, having eaten and I do not believe in the PWO "window". IMO, this was made up by protein powder companies. I don't know about you, but the last thing I feel like doing is eating a big meal after hard training. The powder is easier of course, but I'll take my steak and eggs PWO 2-6 hours later. I train fasted at 530am. I have been experimenting with preserving the growth hormone release, as opposed to the insulin spike of "carb loading", which stops the HGH and have been seeing gains in strength and mass at 6%-8% BF. I figure HGH has quite the anabolic effect. I don't eat cake but if I do, I'm eating the whole damn thing.
Mark Sisson has a nice post on this:
I train both fasted and fed, on a shifting schedule. Comment on this answer if you want the details!
I get slightly better endurance from training fed, and more health benefits from training in a fasted state. I want both good results, so I make sure to visit multiple variations.
To be clear, I don't think I'm training in a fasted state if I have eaten in the last 12 hours or so. I sometimes make sure to train at the end of a long fast, right before breaking into the fridge.
I know that I am consuming some small amount of muscle when training fasted, but I am also consuming fat and any damaged or diseased tissue that I may have on board.
I'm sure this is part of the reason my health has improved so dramatically.
Don't get into a training rut!
