Experiences with fasting

I have just began implementing daily 16/8 hour fasts and sometimes 24 hour fasts. I was just wondering what other people's experiences have been with them. As I am so conditioned to believe metabolism slows down without 3-6 meals?I tend to get really cold during them.I however find have a lot better time refraining from overeating when I just have one satisfying (1000-1500 calories meal) at nightime, my mental clarity has improve, I am less obsessive and anxiety ridden and have more energy. What were your goals with fasting? Do you think/ know if there are any negatives to long term health

Also, I should add that I have been primal for four months and felt comfortable extending my "fast window" beyond my pre-primal days after about a month or so. But, I know people who have made the switch and didn't feel comfortable with IF until five or six months in. Just a theory, but I think it depends on when you fill your body's nutritional stores. Once you have finally fed the body that was starved for nutrition pre-primal or pre-paleo days, then your body can adapt to IFing easily.

yeah i'm really curious too! how long have you been doing it for? did it take a while to get used to and for the anxiety to go away to stop worrying about having to eat?

Hi,

I've been doing the same kind of fasting (daily 16h fasts on the days I strenght train + two 24H fasts a week). I've only been doing it for a month and feel good about it so far.

  • when I eat, I like to eat BIG, so it's easier to split my "daily caloric needs" between one or two meals (I'm not counting though).
  • I also tend to get cold for the last hours of a 24h fast, but it doesn't really bother me.
  • In terms of goals, I'd say I did it for: my wallet (obviously eating less is cheaper) and my physique (less need to be restrictive at each meal).
  • It also allows me to get more work done in a short period of time, without being constantly going on lunch/coffee/snack breaks.
  • I don't think there are any negative long term health consequences.. but I'm only saying this in light of animal studies.

Hi Chelsea,

My personal experience with fasting has been pretty good. I have never really been hungry for breakfast but felt stressed to eat it or guilty if I skipped it - even though I never did the mythical binge eating that is supposed to follow a skipped breakfast. If anything, I always felt more in control over my hunger and ate more normally when I didn't eat breakfast than when I did! I know now that is because I didn't cause a massive insulin spike that crashed, leaving me famished.

So, now I rarely eat breakfast unless I am actually hungry. I would say that, more than the benefits of fasting, I am enjoying the freedom of not having to eat at any particular time and eating what I feel like (within acceptable primal means). On the weekends, I tend to have one day where I don't eat my first meal until around 3 or 4. Mostly this is the result of absentmindedness, but I have noticed a marked improvement in mental clarity on those days. And I feel like I am able to breathe better. I haven't done a 24 hour fast yet, but would be open to doing one when it felt right for my body.

Everybody is different, but for me IF has been more about physical stamina than mental stamina. I have extremely low blood pressure and I get lightheaded very easily. That's probably the only ill effect I have noticed so far. And when lightheadedness starts to turn into faintiness feeling, I immediately eat.

Good luck with your IFing!

Also, I am sure you have already seen this, but this helped put my mind at ease about IF: http://www.marksdailyapple.com/fasting/#axzz1qypK8fkA http://www.leangains.com/2010/10/top-ten-fasting-myths-debunked.html

My experience has not been good. Please be sure you are leptin sensitive before you fast. If you are fine with it now, I say go for it.
