Precise benefits of intermittent fasting with respect to achieving optimal weight?

Answered on September 12, 2014

Hi, PHers. Can someone please succinctly and in layman's terms outline the benefits of intermittent fasting as far as achieving optimal weight is concerned?

Is it simply that when one consumes less calories, she loses weight? Or is there some other mechanism at work? I've read several posts surrounding this subject, and I'm still unclear.

Thanks!

You don't get hungry at all in the remaining 20 hours? If so, how do you stave off hunger pangs?

Go to leangains.com and read there. He's got a lot of stuff. Yes in the end it's about calories. You still have to eat less than currently to facilitate fat loss.

I have had positive results with intermittent fasting. I like to think that the not eating for 16 hours starts to eat away at fat reserves but we really don't know for sure that that's how it works. One very simple and rarely mentioned positive aspect of intermittent fasting is that it keeps you from snacking. And for me, that's really huge.

Brad Pilon has a great ebook called Eat Stop Eat which delves into the scientific aspect of it. The site looks like a rip off, but it's actually not. He's got a bunch of videos on youtube as well discussing the science. Personally, for me, I enjoy IF to a regular schedule of eating. Once you get into it, it becomes easy to eat, say, once a day, and not have to worry about food all the time.

IF isn't used for weight loss. It may be a side effect on some people (not me). The benefits of IF are that it kicks your body into autophagy (http://en.wikipedia.org/wiki/Autophagy) which tells your cells to start cleaning themselves up. That's why IF is good.

It messes me up. I have horrible results from it. I don't plan the intermittant fasts, I just forget to eat for a few meals sometimes, ending up with one. I get soft and flabby when I don't eat enough to maintain good muscle mass and muscle tone, and I lose weight too quickly if I don't eat often enough. 4 to 5 meals a day for me is optimal.

Others... they do great with it. I cannot tell you why or why not. Each individual is well...individual.

In my case, the more I eat the more hungry I become. Happily, it works in reverse. Each day, I eat until satisfied in one 4-hour window, then don't eat again until the next day. This definitely calms my "binge" appetite and since I greatly prefer to exercise in a fasted state, it also supports my goal to be more active.

My personal observation is that it's a way to restrict calories. I've lost a few of the 'stubborn last 10 lbs' so far IF'ing from 6pm-noon, basically just skipping breakfast. I find I'm not hungry at all until I eat at noon, no mid-morning snacking, and no mid-afternoon cravings for a snack. Then after supper, I don't snack in the evening--even though I would like to sometimes... I was maintaining on about 2500 calories, IF'ing has gotten me down to about 2000 calories without the usual hunger associated with calorie restriction.

There are other reasons I've heard why IF'ing is good for you, but some will also say it's bad because it upsets natural rhythms of leptin, insulin, serotonin and all that hormone magic.
