How Often Do You Fast?

Answered on August 19, 2014
Created June 08, 2011 at 4:22 PM

I did my first 24-hour fast yesterday and have a few questions I haven't seen posted:

1) How often do you you do a 24-hour fast? Every 7-10 days? More/Less?

2) Is there a reason to worry about a lack of caloric intake during a fast slowing down our metabolism and contravening the weight loss effects of a fast?

3) Related to #2 above, did whatever weight you lost come back in the days after a fast, or did it stay off? I lost 1.5 lbs during my fast, so I guess I'll know soon enough whether I put it right back on.

Thanks, everyone!

In my case, Travis Culp, it's not a controlled starvation experiment. My body is happy with what I've most recently eaten and is not asking for food.

well, there's my answer. thanks T:) Sleeping for something like 8 hours is enough of a fast for me.

yes the weight will come back right away. that little time and that amount of weight is simply "water weight"

It's abstaining from eating for a sustained period of time. I'm not sure what the minimum time is but I imagine it's around 16 hours. I think the limit people do is 36 hours though I'm sure there's a minority that exceed this. So yes you could eat dinner at 18:00 and eat your breakfast at 13:00 and get 18 hours in quite easily with a workout in the morning - this if I remember rightly IF can also be exercise induced; thus you wouldn't have to fast for say 16 hours; rather don't load up on carbs before or after exercise, so effectively you're not replacing sugars lost during exercise.

1) I don't. Personally, I don't handle fasting well. With my work schedule mixed with CrossFit, I need to eat.

2) I don't think so, as long as your metabolism is repaired from eating SAD. I think (ahem) that with a damaged metabolism used to SAD, it's important to go through a repairing process by eating paleo. After which, I think fasting can provide some benfits, but before, I'm not so sure.

3) That's probably made up of waste and water. It will most likely come back.

I fast everyday. Since it's rutine I wouldnt call it intermittent fasting although I do IF as well. I have a eating window from 9 am until 2 pm everyday, then I do not eat any more after that. I also add in some 36 hour fasts once or twice a month.

Every night when I go to sleep.

Fasting beyond that seems extremely catabolic and in direct conflict with all of my goals. I simply can't fathom why I would want to do controlled starvation experiments. Insulin sensitivity can be improved extremely well via fructose removal and various types of exercise.

1) I usually fast a couple times a month. I will usually fast when it comes naturally, either I'm too busy at work to eat or not somewhere with decent food. Occasionally, I will use it as a "reset" after a particularly off period. I have to be careful with this one to make sure that I'm not falling into a restriction pattern to "punish" myself though.

2) During all of my weight loss I have occasionally fasted, it has always helped, not hurt.

3) If I stayed strictly to my protocol after the fast and didn't use it as an excuse to over indulge when it was over I kept the weight off, every time.

I typically do a 24 hour fast once or twice a month, BUT I do mini fast almost daily just by skipping breakfast and eating a late lunch. I do regular 15 to 18 hour fast weekly sometimes multiple times a week.

You're metabolism will not slow down, it doesn't until after 36 hours I believe. It is not counterproductive.

Weight fluctuates yes, so stop using a scale and start looking in the mirror. Make sure you drink lots of water while you fast. Some days I weigh 167 and other times I am up to 180, but when I look in the mirror I am getting leaner.

Are you working out too. Muscle weighs more...

my fasting is usually up to 18 hours only and I do it naturally after a afternoon snack to breakfast the next day. I do this regularly but if I can't I don't worry about it.

I feel good doing it this way, it works for me without effort or thought. I don't actually do it for weight loss, I like feeling lighter and helps my poor digestion.

I notice more loss when I've eaten more calories (good ones), I may go up or down a few pounds but generally I don't really worry about it. I'm at my goal weight.

I don't really fast, unless you count a late breakfast. 24 hours? Might kill me. Going without fat and protein for very long makes me feel like utter crap (often triggers a migraine). Plus, I need to gain weight, and I can get in the most calories if I eat 2-4 large meals per day.

What, exactly, is intermittent fasting? Is it skipping one meal? Two? A day? Is there a minimum/maximum? If you don't eat breakfast before you CrossFit, does that count as fasted training if you ate dinner the night before? I tend to get dizzy and rather cranky with lack of food. I don't mean pre-crossfit, but if I didn't eat after, or if I fasted for 24 hours or something. I'm not sure it's a great idea to try and CrossFit on an empty stomach... I have often done 24 hour fasts (religious fun!).

I don't keep a schedule. I do it when it comes naturally, that is, when I don't feel like eating a meal or two. I don't notice any difference in my metabolism. In fact, I often feel quite good and alert during IF. As for weight lost, when I first started paleo, it would take the weight off. I'm now approaching my equilibrium weight, so it doesn't shave off noticeable pounds.
