A really interesting article in the NY times today – Coping With Excess

The writer questions whether it is possible for human to evolve such that we are better able to process diets high in calories without packing on the pounds.
Apparently, some studies have been done on rats and catepillars that showed that the later generations of those who were forced fed excess amounts of food were slimmer than than the later generation of those who ate a lighter diet.


Additionally, there has been evidence to suggest that those who live during a period of famine during their younger years are much more likely to become obese later on in life when food becomes abundant again because they tend to develop a “thrifty” genotype that allows them to hold on food for longer periods of time. It is essentially a mechanism to prevent starvation.


I wonder if it would be possible for humans to adapt to be able to eat excess amounts of food though. Obviously, it wouldn’t be an ethical experiment, but also, wouldn’t people just die out along the way? By eating unhealthy amounts of food, you would become much more prone to developing heart disease and other health conditions. An interesting question, though. I would never have thought of it.

    That’s a very interesting suggestion about growing up to be obese, if you lived during a time of famine. I can understand how it’d be part of survival. Interesting!
