Maybe, but it's going to take a long time. For the past 200,000 years or so, fatty and sugary foods were hard for humans to come by and well worth gorging on. Fats help maintain body temperature, sugars provide energy, and craving such food is hardwired: Eating fats and sugars activates reward centers in the brain.
Scientists are finding that the degree to which we experience those cravings can also be influenced by genes. Obesity runs in families, and although scientists still don't know just how much of craving is hereditary and how much is learned, they have located more than 100 genes that seem to be linked to the disease. To evolve out of cravings, we'd need to stop passing down these genes.

The article makes allot of sense, however I have heard about theory’s regarding diet, and diabetes that span only a couple of generations. Like if your great, great grandfather survived times of famine you may be more prone to diabetes, or crave certain kinds of foods. NOVA Ghost In Your Genes (maybe).
