post #55741 of 57266

Does anyone here do intermittent fasting?

 

Is there any benefit to doing it for the shorter term? I.e. doing it for 12 or so hours instead of 16? I could probably go without eating from 10 pm till like 10-12 the next day depending on the day. Always variable etc, but I could keep the time constant. Guessing even light snacks are off limits? 100 calorie bars etc?

I don't want to reduce workout hours too much due to sanity.

I go 16/8. Nut up.

IF is the truth

Not necessarily for weight loss/recomp but just for how much time it saves you if you have a busy job, and how smooth your glucose levels and mental status stay during the day once you are used to it

But I like food and drink a few times a week. Nothing crazy anymore since I hate getting hung over so it happens maybe once every couple of months after a big huge exam or some shit.

I actually have no idea why the 16/8 model is used. Most of the research I've read is alternate day fasting. 

 

Review: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3946160/

 

TLDR: Fasting + exercise -> +ATGL +NE +HSL -liver glycogen -muscle glycogen -blood glucose +AMPK +insulin sensitivity -> +lipolysis +b-oxidation +mitochondrial adaptations for fat oxidation -> +more b-oxidation +fat loss +muscle endurance +time to fatigue -> +muscle glycogen supercompensation

 

Then there's the entire longevity and anti-cancer effect that's generally seen with calorie restriction, except you're not restricting calories.

 

Anecdotally, I've noticed nothing but benefits in training, body composition, and energy while fasting 16/8. Easy to fast while in class etc and eating massive meals is always a treat.

I might try doing it a few days a week and seeing how it goes. I'm also open to trying fasted low intensity cardio. We used to do that when cycling and putting on base miles to get the body better at beta oxidation at lower heart rates, or so the theory went.

 

Some used to take it to the extreme and do bonk rides, where you'd wake up, drink espresso, and go ride with water in your bottles for a few hours at steady state. Goal was to ride till just before you bonked hard. I think some guys rode with a baked potato so they could eat if they started bonking.

You can't do it a few days only your body will need several weeks to become accustomed to it
post #55748 of 57266

I guess I can try doing the 12-14 hr thing then. I'm pretty close to it right now any way.

Nah, I'm probably worse.

 

(I'm also just kinda sorta trolling. Sorry.)

I do a 16 or 24 hour fast once a week. It doesn't interrupt my training routine at all, and I really don't get hungry. Been doing this for several months.
post #55752 of 57266

I dont get how you guys dont get hungry.

post #55753 of 57266
Whenever you get hungry I would suggest one cup of concrete mix so you can harden the fuck up!

Haven't the tenuous links between calorie restriction and supposed increase in longevity been disproven?

Not that I've read.

 

Current literature indicates that the increase in AMPK from fasting / calorie restriction protects against neuro degeneration, cancers, inflammation, high blood pressure, insulin resistance, and prob more things but this is just off the top of my head. 

 

It's why metformin has so many benefits beyond glucose disposal.
