What do you want your national leaders to look like? Do they need to be fit? Does it matter if they have "let themselves go?" William Howard Taft was our heaviest president, and I don't think his weight would make him electable in these modern times. With the exception of Bill Clinton, our recent presidents have been fairly physically fit. George W. Bush jogs regularly, and it shows. However, I don't think that "W" would do what the 54-year-old Russian president Vladmir Putin has done: take off his shirt to pose for cameras.
