I could be wrong
I don't know if not eating at all would be easier than eating less for most people. You may have an iron will.
That said, the health benefits from fasting are based on occasional, even regular but infrequent, fasting. It also may be great for losing 8-12lbs, mostly water but, not the healthiest way of losing any significant amount of weight, and keeping it off for any length of time. One of the side effects of fasting is that it sends your body into starvation mode,(part of why it has any health effects at all, good or bad) which will help you lose weight while you are starving but, your body will try to store any calories taken in afterwards, for fear that it may be put into a starvation situation again in the near future. Part of the issue with losing weight and keeping it off, is to train yourself to eat less(the ONLY way to lose weight is with a caloric deficit, which can be accomplished through fasting, dieting, etc.) and retrain your body to metabolize food more effectively. I'M NOT A DOCTOR but, with my limited experience as a dietitian 15yrs ago, I don't think retraining yourself to learn how to fast most days is the best idea.
I could be wrong and not being argumentative.
Just another viewpoint. I will agree that if you need to lose 5-8lbs real quick, fasting will work.
EDIT Annnd, everyone's different. YMMV
