While I do agree seed oils are bad, they're not causing obesity.

Obesity is caused by overeating, ridiculous portions sizes and sugar drinks

In short, too many calories

Secondary is this idea that fat and meat is bad, but eating meat is the best way to actually feel full and satiated. Without them you end up stuffing yourself with empty carbs (which is sugar) and never feel satisfied.

But I am preaching to the choir here, its actually very rare to find an obese bitcoiner.
