Historically, beauty and wealth have correlated - there have been times that being overweight was a sign of wealth, and considered attractive. In medieval times, (for white people) being thin and tanned wasa sign you are poor and work in the fields; being fat and pale was a sign you were comfortable and did not do manual labour. Corresponding standards of beauty tracked with that.
These days, the reverse seems to be true. Millionaire movie stars are often thin and fit. It's a sign of wealth and success.
Wealth and health correlate even more strongly. Being poor could mean dying of malnutrition. So the beauty-wealth-health signalling mechanism was doing its job properly there, telling you who was the "fittest" mate from a Darwinian perspective. (I doubt that grossly obese people were considered beautiful even back then even though gross obesity is a clear marker of extreme wealth--"pleasantly plump" is about as far as I'd find plausible based on what I know of art from the period.)
Nowadays, thin and fit people are likely to live longer than overweight people, so it's not at all inconsistent to see that as the new standard of beauty. Dying of malnutrition simply isn't a risk for most people any more, so plumpness no longer carries any information about a (Darwinian) fitness advantage.
