> If you want to beat obesity start by buying just the ingredients and then cooking meals at home. It's not that hard. Then start walking to places instead of taking the car. Taking public transportation is also good because it frequently forces you to walk a non-negligible amount. Also stop eating while watching TV. You can go one step further and throw out the TV altogether.

This all seems pretty strange and won't make you lose weight. What will is just eating fewer calories. That's it. You don't have to change anything at all if you don't want to. You can drive to the store, you can eat in front the TV, you can eat your hamburgers and drink coke. Just eat less of it, and you'll lose weight.

The idea that people have to be "educated" to know this is ludicrous, such a typical "government" / "expert" notion. Eat too much = get fat has been known and understood for centuries. People knew this when they were illiterate peasants. School children tease each other about this. The obesity problem is not caused by lack of education, it's caused by lack of self-control (exacerbated by the refinement of food composition, improved cost and convenience, and marketing).
