Eating once a day will get you in touch with hunger....I think its great. Many people don't get to feel truly hungry around here. They get that well I'm bored and I could eat, so I guess thats what I'll do kinda hunger. Eating once a day I don't think the hunger will ever go away....I mean thats the point. You SHOULD get hungry. By hour 20 or so I start really looking forward to my dinner in 3-4 hours. And thats natural.
Not that you HAVE to do it, but some of us can and in a sadistic way even enjoy it . There are a lot of known positive physiological up sides to it and many more theoretical probabilities as to why it is healthy. So even if a 24 hour fast isn't a daily thing it cant hurt to throw it in once in a while with periodic longer ones to boot.
