Exactly. Humans don't have a fat problem, for example - they have a motion problem and an appetite problem. We are evolved to take advantage of excess food supply, since the next season may be lean. Our bodies are finely tuned to balance the need to store energy vs. the need to accommodate the level of activity we typically use to survive. Unfortunately, in modern society, both those points are now at an extreme end of the spectrum.

Does it matter, evolution-wise? Not really. People don't choose to have children based on their appetite or body mass. Only the extremes - the people who weigh, say, 400 pounds or more - would (maybe) find that an impediment to reproduction - meaning in a millennia or two or five, maybe the tendency to have "run-away" obesity cases would be less. .
