Personally, it doesn't bother me that much because by the time I get a minibike, I have usually already built up a solid self-sufficiency. And since I do a lot of melee combat, my food consumption is generally much higher than for somebody who mainly uses firearms. So I barely notice it.
I guess the Fun Pimps wanted to make hunger a slightly bigger problem to overcome. In the past, there have been some complaints from players that you can't actually starve because you find so much food.
I understand why players do not like this change. You can mitigate this problem by drinking Red Tea and invest a point into "Iron Gut". My strategy is to invest a point in "Master Chef" right at the start. Then I can make bacon with eggs which is a good starting point.
