Obesity was always seen as a sign of wealth historically because in those times rich people were the only ones who could afford to eat enough to get fat and didn’t have to work in hard labor for a living. That’s no longer the case. There are plenty of very poor people who can still afford food just not good food and very few people work hard labor like those in medieval or renaissance societies did. Historical circumstances and reasoning don’t really apply here as societal norms have changed so much since that time.
