This is true, so far as I know. When Franklin was in France negotiating various matters, he noticed that when they broke for dinner (aka lunch), that the other diplomats would sit down to a quite lavish meal, but would later be somewhat groggy and slow.So Franklin would eat just a VERY SMALL meal--a salad, say--and when he went back to the negotiating table, he was bright and bushy-tailed, so to speak, giving him a decided edge over those who sat across the table from him.I have used that before when I was at, say, some business conference and knew that I would be nodding off if I ate a large lunch, etc. Also, I have heard that intermittent fasting is somewhat akin to interval training. That is, your body gets used to eating regularly, then you mix it all up and don't eat the same way, which makes your metabolism not get settled into a particular routine and become less effective.I heard or read that Kenneth Hagin felt the Lord wanted him to lead a fasted life, instead of just fasting at this or that time. So Hagin's way of doing that was to never eat to fullness. To simply eat a small, set amount, then stop. Period. Of course, if that goes on long enough, then even if there are spiritual benefits, the metabolism starts getting into a routine.
