You would be penalizing people for decisions made by the food industry. The very large and powerful food industry. In America, you already usually pay more money to get bread without corn syrup added to it (as just one example). It's in almost everything. YOu pay more money for the equivalent lower calorie/more natural food. Add on to that the fact that most Americans are no longer taught to cook whole foods (most never have a single Home Economics class in their education), and you have long term effects from decisions made by large social systems. Yet, we blame individuals, no matter their social class or individual biology.

Force the individual to take more responsibility for their own choices? By reforms like making soda more expensive? Soda taxes are not an individual choice, they're a systemic solution. Look, you've been saying a few things that are contradictory, so I don't think you have a really well formed idea about what causes fatness, either on an individual or population level. I'd suggest looking into the research a bit more and seeing if you can reconcile what you find with your ideas about how humans work, both individually and as a population. If you can't, then it might be time to update some of your beliefs. I don't think either of us have anything further to gain from this exchange until you do. Have a good one.
