Just because folks had access to tons of fats and such doesn’t mean that this is causal to gaining weight. It has to do with how good everything tasted. The ability to have food that’s just delicious has never been easier. Not just access to spices and seasoning, but access to premade ingredients that enhance taste. That also doesn’t even account for access in terms of cost. It’s never been cheaper to get calorically dense food than the modern era.

Honestly, have you looked at a 100 year old cookbook? Most of the recipes are… crude in their implementation, to put it mildly.
