Why isn't there a fight against unhealthy food like is for drugs?

Yeah, losing weight really is as simple as diet and exercise, unless you have something wrong with you. People try to make it sound more complicated to make themselves feel better, but it's completely about willpower. You can eat less and not exercise. You can exercise a shit load and not eat less. Those are your options. Sure, you can switch out shit foods for healthy foods and lose weight, but you'd still have to consume foods that take fewer calories to burn than what you were eating before.
