Sometimes nature comes up with elegant solutions to difficult problems, like how to gain weight and not get diabetes.
Take, for instance, the grizzly bear. How does this 750-pound mammal survive long, lean winters? Well, it just gets really fat beforehand and then sleeps the hungry season away.
Grizzly bears can easily double their body fat in the months leading up to hibernation. For us humans, this kind of weight gain could result in some pretty serious health consequences — one of the most common being Type 2 diabetes.
