Sugar isn't the cause of obesity though. I think people that try to blame it all on sugar are simply looking for a scapegoat. It's easier to actually over eat on fat than on sugar because of a higher caloric density. Carbs are just cheaper so they get added to everything as bulk.

Overeating on just fat and protein is actually something your body can handle and even leverage over time, though.

Also let's not overlook how alcohol could contribute to obesity either.

You get satiated much faster eating fat than eating sugar. How much butter can you eat? How much fruit juice can you drink?
