Good start but not quite far enough. Have a body fat percentage measure or BMI rate at fuel stations so that their gas is increasingly expensive, make them pay more for public transport, don't let them on the plane if they can't do a pull-up, make them park at the end of the parking lots, don't let them eat fast food/drink sodas... Provide prop  25e4  er incentive for them to skinny up and bleed them dry while you're doing it
