I guess you are talking about life expectancy being way lower back in the day. Those numbers are massively skewed by infant mortality and so many other things (infections, complications during child birth, ...) that are nowadays easily sorted out by antibiotics and other means.

There is literally no reason to believe that what people are in the areas they lived in with the technology they had was somehow better for a person than regular food today. It pretends that everyone are the same food and that the food was somehow optimal rather than just what was available.

Its a bunk premise.

What regular food today? The processed food from hypercapitalism that led to obesity to 40% of the population?

But I broadly agree with you. Food, exercise, and luck in avoiding sickness. It was true throughout human prehistory and today as well.

What led to obesity is not the food per se but the wide availability of it and the change in other norms like exercise and outdoor play which changes lifelong habits. Even with a world of processed food it's rare to see a fat person who is a daily runner and that is no accident.

But this theory that humans used to eat an optimal diet and now don't assumes that humans in the past were somehow in more control of their diets than we are today and I don't think that's true at all.
