Obesity is caused by lack of access to quality food, being too scarce or too expensive. Sugar and fats are cheap, so most of the pre-made foods are just that. So increase the quality of the food available to the masses and do proper education regarding nutrition and healthy living, and the obesity rate will decrease.

Most of the obese people are like that not because they choose, but because they cannot do better.

There is nothing wrong with fat.

People were cooking with lard for 1000s of years until the US decided fat is bad and people started substituting fat with sugar because when you remove fat, you remove flavour.

Don’t forget people also died much earlier for thousands of years.

There is a great deal wrong with very high fat diets, the issue is there’s also a lot wrong with very high carb diets.

In some cases yes, but hardly in all cases.

Anecdotally, I know people with the same wealth as me or even wealthier who eat copious amounts of sweets in all forms and are also obese. Some people just don't have control.

But yes, proper education regarding nutrition is something that is sorely needed as most people are unaware of the dangers of eating sugar rich and calorie rich foods in large amounts.
