For a colonoscopy. Not a whole a lot of fun.

For what?0

That is a great way to get your body to hold onto every fat cell you own. In my opinion, by not eating, you put your body into a self preservation mode.0

I admit that I tried it once and I don't recommend it. I lost a tiny bit of water weight that I promptly regained when I started eating again. And I felt physically ill. I wanted to sleep all day. I understand the temptation but it's just not worth it. Plus it should be noted that so-called cleanses do not "detoxify" your body (your kidneys and liver do that on their own) and long-term they can actually slow your metabolism and cause other health problems.0

*shudder* I have that coming up sometime (thanks, Dad!), awaiting a mystery call from Health Canada.
I've never done a 24 fast and wouldn't except as a medical necessity.0 -
@kkenseth ok then, if it doesn't hold onto fat, what does your body function on, when you deny it of nutrients?
It burns through what glycogen stores you have, then starts burning through fat stores. It's not going to do that in 24 hours, but "starvation mode" as you're describing it is a myth.

I fast 4 days per week for 16 hours in an effort to maintain weight and lose body fat.@kkenseth ok then, if it doesn't hold onto fat, what does your body function on, when you deny it of nutrients?
It burns through what glucose stores you have, then it starts in on your muscle. It's not going to do that in 24 hours, but "starvation mode" as you're describing it is a myth.
It's been a slow process, but I maintained 180lbs and dropped body fat from 23% down to 15%.
This was over 2.5 years, so it's not some miracle pill.

No, that's completely wrong. The human body evolved specifically to run well in fasted conditions. A 24 hour fast is nothing - you need to go past 72 hours for the first hints of Bad Things.0 -

That's AWESOME. I don't think OP is as experienced as you are in body recomp though. I could be wrong.

I feel you on that one. I live off nothing but sugar free jello and diet coke when I'm testing my basal insulin rates. It requires a minimum of eleven hours of fasting (five hours to clear any mealtime insulin plus six+ hours for the basal test), and it's difficult not to kill anyone during that time.0 -

How often do you have do that? Because fasting really sucks!!0 -
Just for religious reasons. I don't even totally fast any longer. I'd get woozy. The deal with most of the religions in the US is that being hungry is okay, hurting yourself isn't. If it's going to hurt you or make you sick in any way, you don't fast. So, I kinda fast now.
Fasting to lose weight is not the healthiest or most sensible way to go about it.0 -
I do a 24 hour fast two or three times per month—usually after a day or two or three of 3,000 calorie days. It is really not so difficult. I think I would find it more difficult to try to get by on 1000 calories than none at all.
Kkenseth is right. Starvation mode takes two to three days to kick in and only results in a 20-30% drop in your metabolic rate. The vast majority of us have plenty of fat stores to feed the machine during a one day fast. Those that don't, aren't fasting.0 -

Did it for spiritual purposes - not just for weight loss
Longest I've been without food and water is 3 days - for spiritual purposes. Was weak, couldn't pray much and kept on thinking about food

Technically, I should be doing it any time I think my basal insulin rates on my pump need to be adjusted (which can be on a weekly basis depending on hormones, weight loss, and any extra activity), but the test stinks too much for me to do it no more than once every six months. I still haven't been able to fully solidify all 24 hours of my basal rates through testing -most of the time, I would fail the test (typically by experiencing more than a 60mg/dL change in my BG over the six hours), adjust my rates accordingly, and not test again because of how much of a PITA fasting is.0 -

Man, that is tough. Sorry to hear that.0 -
I have done it once a month for most of my adult life, not for weight loss reasons but for religious purposes. I found it to have zero affect on weight loss. When coupled with prayer it is spiritually powerful.

I've done about 3-24hr fast but mine were for spiritual reasons. Lots of prayer for strength and a closer connection with YHWH. As far as weight loss it works in the short term. When I break fast I can't eat as much because I get full sooner. Usually I drop about 2 pounds. I also dabbled in fast such as the 12/12 and 14/10. I really didn't like those after a while because I felt hungry. Once I went back to eating normal my weight loss plateaued and the only way to lose more was to do another 24hr fast.
In the end I feel like my metabolism slowed down because the scale wasn't moving on a normal calorie amount. So I did a refeed for 10 days and then reduced by 500 cals and now I'm able to lose weight eating 2100 cals a day.
A spiritual fast every now and then is good but I honestly couldn't imagine doing a 24hr fast just because. Good luck with whatever you decide.0 -
I've done reduced calorie day of 800 calories after I had a day of 3000 calories. I also did something similar before and after a cruise I went on. But I've never gone completely without food...that's crazy. And honestly there's no reason to put yourself through that. 0

I've done numerous 23.5 hour fasts over the years, where I eat only once a day. Sometimes up to 4-5 days in a row. It's a great way to limit what you eat simply and easily.0

Fasting is of those things you do because you have to, not because you think it's fun, unless you're mad or stupid, or both.0
-
Nope - that's not how it works either. You absolutely don't have to be completely glycogen depleted to use fat for fuel.

Look up intermittent fasting and the benefits as it applies to 24 hr fasts as well.0
-
I've done it for religious reasons...and then I stopped being religious.0
