Who will get the food?

Based on a new report out (yes; another one!) it seems that we will be in a battle with the worlds obese to see who gets the food. The United Nations is projecting that there will be 9 billion humans by 2050, and as the obese eat more ,their bigger bodies will gobble up even more resources.
So.... As the worlds resources dwindle, the supply of food gets less. Hence a fight to see who gets food.
Shades of canabalism......
