I think comparing our diets to bears does not make sense at all … our systems are completely different.

A bear can eat massive amounts of food in a short period of time, gain lots of weight and then fast for several months and go to sleep and do nothing.

If we tried the same thing, we’d probably go into cardiac arrest, or some serious intestinal problems if we ate too much too fast in a short amount of time … and then we’d ruin our kidneys and liver and probably die of starvation if we went on fast after.
