Breaking a water fast

I frequentlty do a 24-48 hr water fast. One thing that comes up about water fasting is how our ancestors used to "fast" (not intentionally) during times of no food, etc. And, that our ancestors were healthy due to their fasting.

However, when our ancestors broke their fasts, do you really think they started off with something light, etc? If they just made a kill, they would probably be gorging on that buffalo or whatever...
