I recently read about a study done by the Salk Institute ( http://www.kpbs.org/news/2012/may/17/salk-study-may-offer-drug-free-inervention- prevent/ ) where they tested two groups of rats, giving them the same food, and an unlimited amount, but one group could only take advantage of the food for eight hours a day, and the other group could eat whenever they wanted. The 8 hour feeding window group were in better physical condition out performing the other rats and were much more healthy overall.

I thought it was interesting, so I've been trying it for the last week. No real physical changes yet, but the amount I can eat when it's eating time is AMAZING, I really haven't been able to eat like this since I was 17. I've also been eating whatever junk comes my way, and no weight gain, or change in muscle tone so far. It's been interesting so far. I'm going to finnish out October on this diet and see if there are any changes.

Anyone else done this kind of intermittent fasting? How did it make you feel? What were the results?

Having fasted a month out of a year for decades, I can say I am not a fan of the diet. Having no food or drink from sunlight to sunset will definitely allow one to loose weight, but maintaining one's normal workout routine, among other things, is difficult.

There have been studies on high fat diets. In the last 15 years, there was one study done on Amish people, who are raising barns at 5am and work until well after the sun has set. They have a diet high in fat, including lard, butter, and whole milk. They burn more calories than the average American, given their life style. I'm not sure if their eating schedule would qualify as fasting though.

A large study was conducted at Cornell University a few years ago, and they found no difference between the mixture of carbohydrates, fats, and proteins that led one diet to be superior to another.

Japanese people, who have the longest lifespan on the planet, have higher incidents of heart disease, obesity, and other risk factors when they move to the United States. Some of that can be explained by a change in diet, other explanations by life style choices.

From personal experience, I have found that I lose a lot of weight, and keep it off, when I spend time in Asia. My diet in China consists mainly of carbs (noodles or rice) and vegetables. My meat consumption in China decreases dramatically, as they tend to use it more as a flavoring than the center piece of the meal.

I did gain some weight while I was in Japan, as they have more meat in their diet (fish) when compared to the Chinese. Granted, the weight I put on was lean muscle, as I was training twice per day at the Kodokan.

I should also note that I felt much better when I reduced the amount of red meat I consumed in both countries, as compared to my diet in the US. It was easier to keep the weight off. My sleeping patterns were normal, and I felt like I was better able to concentrate (ie, no caffeine or sugar cravings in the morning).

Food blocks chi from flowing. try eating a full meal and working out right after. you will likely vomit because your body is trying to clear the channels. same reason why animals defecate in extreme fight/flight situations.

Weight loss is caloric intake vs. calories expended

I have.

Thanks Tim. How did you feel while doing the "Leangains" Diet?

I felt good, I did have trouble eating enough during the 8 hour feeding window, I found I could only eat two meals, and not enough per meal.

I now usually go 12 to 14 hours maximum between the last and first meals, and am able to eat at least three times.

aren't all your days "workout" days?

Seems like I've been seeing lot's of people saying that 12-14 feels good to them. I'm really liking this 16 hour so far though. I have enjoyed eating more, and feel pretty strong even in the morning class before I've eaten. I think in November I might try this diet with Paleo, seems like that might be a great combo.

I've been eating lot's of junk just to see how the fasting interacts with crap food, but good food and this fast seems like a winning combination.
