Hard to know what is doing the obesifying, probably some mix of sugars and toxic chemicals but given our capitalistic society and desire for freedom and free markets it is unlikely we can undo pandora's box there...

The main issue is you do lose muscle mass so it is important if you don't want to look emaciated to also do weight training.  But even if you don't do weight training it's still far better than the poisonous side effects of being fat.

The drugs may appear to work well, but I read an article somewhere about how they totally ruin your health when used for weight loss. I have to agree that there is no real magic pill. i also understand that seed oils are doing a lot of the “obesifying”.  There is evidence that the real era of obesity didn’t start until the late seventies, along with heavy use of seed oils and the downgrading of traditional oils like animal fats.
