Thank you. So yes, the idea here is that the fatties become fearful of being "picked up" by the fat-detection systems. This will modify behavior, or the fatties will join into one colony and the ground will implode causing them to fall to the center of the earth and be redistributed as minerals. 

Now we do have to solve for things like pregnancy but I imagine there's some math we can do between belly circumference, breast size and maybe some other things. This will be easy tho so nbd.  What else am I missing?
