This doesn't really follow. Animals that suddenly find themselves an abudance of food don't grow massive, rather they reproduce in greater numbers. If food were always highly available then we might select for large size and big brains over time, but any one person with too much food is not going to suddenly become superman.
I'm not an expert in this, but my guess is that our energy hungry brains are one of the factors in the relatively long development period for our offspring, but it's not the only factor.
