In brief: Thrifty gene theory
There are some that speculate that a gene exists that helped humans many years ago to survive during years when no food was available.
The gene makes the body very efficient in it's use of proteins, fats, and carbohydrates. People that have the gene will tend to gain weight today with abundant food available.
