Is this what is has come down to?
I'm very ambivalent about this. While some people are so grossly overweight, they need a vaccine to stop the upward trend, but on the other hand, I can see this vaccine become an excuse for others to gorge themselves on sugar and fat, thereby inducing heart disease and other health problems.
It all comes down to lifestyle. I know, it can be a glib thing to say. I have four kids and I know that it's easier said than done. But truth is truth. If you eat all day and you don't walk or exercise regularly, you will get fat very fast.
