I think the people who want the world to be vegetarian for non-health related reasons (e.g animal rights advocates, environmentalists) push the largely discredited "saturated fat is bad, carbs are good" dogma because saturated fat is mainly present in meats and not in vegetables with some rare exceptions such as avocados and tropical plant oils. Also, carbohydrates are not present in meats, but plentiful in vegetables.
