CX have an amazing conversion ratio of intake to growth. As we consume these birds do we change too? Do we also adapt this ability to better convert our foods to growth (fat).  
According to a few studies on the genetic level we are seeing changes to DNA based of the foods consumed and the growth of traits of the food consumed.
Consider the growth of Humans over the past 1000 years. On average we have grown about 5 inches. Why? Most likely reason was the abundance of foods.  
Now consider the mutations of our foods over the last decade. We have developed these giant Chickens, Turkeys, Pigs and cows all through domestication and selective breeding.
Which is all great. Lots more food for everyone. The problem is out bodies are now also growing just as we have bred our animals to. We are what we eat!



Perhaps, though color me skeptical.

That said, if we take your theory as writ, obesity is still a matter of people overeating.  It just becomes perhaps a little harder to keep caloric intake below burn if we indeed are more efficient at extracting calories from food.

However humans are already incredibly efficient at processing our food.  As a percentage of body weight we eat comparatively little food compared to most animals.  Around 2.5% is typical per day, vs dogs (raw fed) at around 3-4% and broiler chickens at 8-10%.
