Hi All,
I have been doing IF for more than a year and I truly recommend it to everyone I meet (who cares to listen
). There are a few different ways you can do IF but the major benefits comes around 14 - 18 hours into the fast. The benefit of course being that the body burns fat instead of energy from the food you ate. Actually after about 8 hours into the fast (yes, while you're sleeping probably) the body switch over to burning from fat because there isn't anymore energy from food to burn.
I started out with 24 hour fasts once a week and those are ok to do 1 - 2 times per week (not more because you just won't get the same effect). Recently I have switched to the 16/8 approach and do that 3 times per week instead. This means that you fast for 16 hours and eat 8 hours. For me it looks like this.
- Stop eating after dinner time, roughly 7 PM
- From that point on only drink water, coffee or tea (no milk)
- I skip breakfast (of course) but drink 1 liter of water and have a coffee
- On my way to work I realize that coffee and 1 liter of water isn't the best idea when stuck in traffic
- I work and then go to lunch with my collegues around noon or 1 PM
That's it, really easy.
The myths:
I'll get hungry and cranky because of low blood sugar!
Actually this was what I thought as well but it didn't happen the way I thought it would. Sure I was hungry in the beginning, but it wears off when you start working and drink lots of water. After a few weeks this will not be a problem for you. Don't believe me? Try it out for 2 -3 weeks and get back to me!
The crankiness I thought would be my biggest problem. I'm really really cranky when I don't get my food, or that's what I thought. But I think that this is because blood glucose goes up and down and when on a fast the blood sugar is even which make you feel pretty good actually.
An interesting side effect is that your efficiency will go up, as will your focus. My most productive hours are the first half of my fasting days, before I eat. You'll notice a laser focus, and you'll get things done. Sounds a bit like a commercial, I know...
There are some research challenging the common understanding that we should eat 5 meals per day etc and there's also research in favour of IF showing a lot of major benefits to this way of living. This is the way we used to live. We used to hunt and eat while we had food, then there were periods with less food. So we're it's not entirely true that we have to eat 5 meals per day. We've only been doing that for the past 50 years or so.
I'm not a scientist or anything but I'm happy to answer any questions since I've been doing this for a while.
Take care!
