To sum quickly - two groups of mice fed a high fat diet - one group they only let feed for half the day. Mice consumed same amount of calories but the time restricted mice did not become obese!
This doesn't indicate the hours that were restricted, lets say it's 8pm- 8 am, those are the hours most people eat and we have plenty of obesity.

I was hoping you'd chime in sci. Yes, IF does seem to be studied more with lab animals--probably b/c you can't pay people enough to starve, lol. And fasting is easier with rats than trying to figure out the rat equivalent of an Atkins diet. But yeah, healthwise and weightwise it seems to look promising. Maybe it works b/c you're not keeping your insulin level high all the time. For me, the weight loss will be secondary--it's the amount of energy I have and then I forget how great it was when I'm not doing it. I'll let you all know how it goes.
One thing I know, low-carb was a fail. Gluten free was a fail. Tried the cabbage soup diet once and got royally sick of the stuff and didn't lose a pound. Did that Mayo clinic diet once where you eat this totally scripted diet for 3 days and are supposed to lose 10 lbs. The only lb I lost came back the next day. You'd think I'd learn. Even if the only reason this works is from calorie restriction, it's still easier to follow than anything else and I suspect it's how thin people eat--thin people actually forget to eat sometimes!

The abstract said the mice were only fed at night so I'll assume it was 12 hours a day access to food. We humans have better mechanisms for dealing with starvation than mice -for example our glycogen stores will last for about 6-8 hours -- so to get this same effect I'd speculate it would require eating just one super large (>3000 calorie) meal per day and that is all - I guess the man vs food guy had it right the whole time??

I have a couple ideas what might be happening But I'd like to actually read the article first. hehe I would definitely say wait for more research before you begin the 12 on - 12 off diet plan

A rat's 24-hour period is the same as a human's 24-hour period. They're both 24 hours, they both are measured by humans who use 24 hours to measure what humans call a day. No idea what rats call it - maybe it's called "squeak" to them.
I don't know about anyone else, but I stop eating for the day no later than 7pm. I don't start eating again until around 8 the following morning. So I go 13 hours without food, every day.
I'm not seeing any relevance at all to any of these studies, applied to me. I'm not seeing that I'm fatter than anyone who doesn't "fast" for 13 hours every day, I'm not seeing that I'm thinner than anyone who doesn't "fast" for 13 hours every day.
What I am seeing, is a wide variety of people, in a wide variety of levels of fitneess, health, and fatness, who -also- "fast" for 13 hours every day.

But you have to remember the metabolism of a mouse is different - a 12 hour fast for a mouse might be equivalent to a 20 hour fast in a human. The authors of this paper went on believing that it has to do with the circadian rhythms which is also probably different between mouse and man.

Well I think it's an interesting study w/o getting too much into the mechanics of how many hours the rats are going between feedings. Just the fact that they are eating the same amount of calories and getting different results is interesting to me.
I think that for me, the reason it's easier is b/c I'm not that hungry in the morning anyway so skipping breakfast is no big deal and then if I don't eat and get the juices flowing, so to speak, I don't really think about food as much anyway. There are those who postulate that this may come closer to matching what our ancestors did b/c they would have had long periods of hunger, broken up with big feasts--it's not like they could just pop something into the microwave when they were hungry or eat a bowl of cereal. Also, I ate last night at 7:00 and it's 9:00 am now and I probably won't eat anything till lunch and I feel really lean right now.
I have no immediate plans to do an all day fast but may try that sometime. I have known people who swore they kept their weight under control by doing a 1x/week fast but it wouldn't have to be strictly for weight control reasons as people have other reasons for fasting such as religion and cleansing. This would not be for everyone but so far it works better than anything else I've ever done. There was a caveat that anyone who has ever had eating disorders should not do this. I'm clear of that one but won't bring it up with my older dd.
Another observation is that it seems to calm food addictions. Last night I kept thinking about the chocolate in the cabinet and I had given myself permission to eat some if I wanted it but I never did get up the gumption to go eat some. I just figured I'd have it later. That is very unusual behavior for me. Maybe it's the putting space in between meals that causes me to think about food in a more rational manner.
I do a 12-16 hr fast at least once a week (skipping breakfast). Almost 24 hours last saturday when i skipped lunch too. Too busy to eat. I dunno if it really helps with fat loss but certainly no ill effects. The 6 small meals a day thing is rubbish, or a crutch for those who need to be told to put the fork down. I know some have "low blood sugar" issues but I wouldn't be surprised if they could be weaned off that over time with proper diet. IMHO that's just pointing to another underlying issue that should be taken care of.
Another pound--woo hoo! 3 lbs gone just this week and that's after 8 weeks of barely successful low carb dieting and I feel better.
Congratulations on the loss!
You my have shared this in another thread, but I haven't seen it yet... What are you eating now if you're not doing low-carb or grain-free? Is it the usual fruits, veggies, low fat, lean meats? I'm just curious because I would not be able to do any IF if I wasn't on a pretty low carb diet; the cravings would cause me to cave and eat every time.
