I do occasionally. Bookend it with 1+g/lb protein days and do some moderate lifting during the fast to encourage the body to burn fat, no muscle. Lots of water. You'll feel a little odd after ~24 hours because your body will have burnt through all the glycerol stores in your liver and is now burning pure fat (or muscle if you're doing it wrong). Do things to maintain as high of test level as you can, moderate lifting (as mentioned), cold shower, no fap.
There are a lot of resources out there, if you're smart and take a lot of care before, during and after you can lose a lot of weight and minimize muscle loss (which it is almost impossible to avoid, but it can be mitigated by a great deal).
>>32091794 >Does /fit/ use intermittent fasting? I do.
>Does it work? Depends on what you mean. Do I buy the broscience behind it? No and I honestly don't care. It works as an organization system to help you stick to your macros when on a cut. I do 16/8, which sometimes ends up being closer to 18/6 or even 20/4 on busy days. My eating window generally begins at 3pm. In the morning I'm either very busy or fast asleep, so I find it easy to remain fasted well into the noon. It takes a week or two for the body to get used to this, but eventually you'll stop feeling any hunger at all during those hours. Then 3pm hits and I can begin eating, usually until like 9 or 10. If you're eating relatively well, meaning generally nutritious stuff that you prepare yourself, then you'll pretty much be full and satiated for the entire duration of that window and then some. You gotta cram a day's worth of food into 6 hours, even on a heavy cut, there's no way you'll be hungry. Then after that, or a couple of hour later, you go to sleep. You're obviously "fasting" while you're asleep. Then you wake up again, and so begins another busy morning during which you've trained your body to not expect food. Rinse, repeat.
For me, that's how it "works". I don't know about insulin responses and growth hormone production. I know it makes it easy as fuck to stick to my caloric goals.
>Do you loose strength? No, why would you? Not any more or any less than you would if you ate the exact same calories at any other point. To be fair, I lift in the evening, after I've already consumed most of my calories. Maybe lifting at the end of a 20 hour fast will weaken you, I'm not sure. I did lift in the noon many month back while doing IF, but I was riding the noobgains hard, so I can't assess properly.
>>32092028 Pretty much on point, fuck the haters just cause he threw in a little debatable science.
What he is doing is the "proper" lifter's program for IF. Gotta "bookend" the fasted day with plenty of protein and lifting so that your body remains anabolic as far as your muscles are concerned. Good stuff.
>Does /fit/ use intermittent fasting? Yeah, every 2 weeks, 1 - 24hr. period of fasting
Does it work? Honestly can't say. I do it so infrequently, and mainly for the HGH benefits (not focused on fat loss) and I can't say there is some enormous difference. I do feel quite good during/after the fast though.
Do you loose strength? Not at all. Especially since I do it once every 2 weeks anyways, so it's only 1 day without optimal nutrition.
>>32096189 >HGH benefits HG is katabolic, its the IGF-1 thats anabolic, and gets released if theres a high surge of HG. The HG surge induced with fasting or high proton meal isn't sufficient to release the IGF-1 (insulin-like growth factor), thereby its only katabolic.
