However, if people need a little help managing their battle with food, I'm all for it.

I'm a thin person with great self control when it comes to food. I consider the impact on my weight before eating anything. Many people, however, are unable to do that. They want to be thin, but they want their super sized drink or muffin or whatever even more than they want to be thin.

If a simple shot in the thigh can help them not want to eat, I'm all for it. I've never been heavy, but I imagine it would be awful. We have a good solution, finally. We shouldn't shame anyone for using it.
Not using it would be stupid
