I read about this in today's newspaper. Basically it refers to limiting your food intake to just 10 hours a day. For instance, breakfast at 8, last meal at 6. For me it would work better if I waited until 9 to eat breakfast as my usual dinner time is 7. My problem would be not to snack during the evening as I seem to get off to sleep better with something in my stomach.
The improvements noted in the trial subjects were, among other things, lower blood pressure and cholesterol (both of which are high for me and require medication) and better sleep. However, subjects had to be careful to avoid dehydration. Also, by following this regime, their caloric intake was reduced resulting in some weight loss. This wasn't the goal of the program, rather allowing your organs to recuperate during the rest period. I'm all for that!
I might try to follow this for a few weeks and see how I feel. Getting a better night's sleep would certainly make it worth while. I know I will find it hard as will power is not one of my strengths!
