a bear is a perfect example of an mammal that uses its insulin response during glut times to store fat.
1. gain weight during the summer by eating high sugar, high starch, high calorie foods such as fruit, berries, roots, honey/insects, and as much whole fatty fish as it can get its hands on for a super high calorie kick. it HAS to gain weight in the summer, and does so easily on that diet.
2. during the winter it hibernates and burns nothing but fat, losing the weight and avoiding starving. people can do this too, believe it or not. fasted ketosis is a thing you can sustain for quite a while as long as you drink water.
this doens't prove anything in humans, but is an obvious counter-example to no evidence to believe that mammals don't have food glut adaptations.
but just for anecdotes' sake, what does an obese human typically eat? exactly the same diet. high sugar (soda/fruit juice), high starch (all junk food), roots (LOTS of potatoes, mostly fried), and extremely high calorie kickers like cheeseburgers and pizza to ensure a calorie surplus.
- jamesaguilar 13y agoUm. Bears don't have a glut in the summer. They eat everything they can and some still die from not getting enough. A glut is when there is so much food that you can eat more than is healthy. You don't see bears passing up salmon saying, nah, I had enough.
- beachstartup 13y agodefine:glut in google says "an excessively abundant supply of something." i'm pretty sure if a bear can gain hundreds of pounds in a few months, there's an excessively abundant supply of food. if not, well, there isn't a glut, now is there. and there's soon going to be no more bear, either.
- burgreblast 13y ago> You don't see bears passing up salmon saying, nah, I had enough. I thought it was interesting to learn from Alaskan's that when salmon are plentiful, bears will gut the salmon and just eat those tasty eggs. Who knew? My mental picture had never included them possessing much of a palate. This article suggests they also go for the brains and skin. http://grizzlybearblog.wordpress.com/2010/07/21/grizzly-bear-eating-salmon/ http://grizzlybearblog.wordpress.com/2010/07/21/grizzly-bear...
