I agree, a direct tax/fine/rate increase would do way more to combat rising obesity rates. It is simply to hard to just tax all unhealthy foods to decrease the supply of unhealthy foods. It makes way more sense to tax an individual for their lifestyle. Plus there are two obvious counterpoints to taxing certain food groups. 1) The food is not inherently bad, only when overused/abused, moderation is key. 2) You can get fat eating healthy shit too if you eat too much of it.
