Losing weight or being thin are not evolutionary goals. People’s bodies are full of mutations or long-term genetic factors that can kill them, and they haven’t all been evolved away. Since this is a long-term risk that hasn’t killed him for years it won’t have impacted his primary breeding and evolution may well have left it alone.

Surviving through periods of low food availability (=eating less calories) is a very strong evolutionary goal.
