It can't be for lack of trying at all.

It may be for lack of trying in a little more intelligent and unbiased manner.

I think there's two really big reasons.

One is intrinsic to the problem.

One can never start smoking.

For some people, as difficult as it is, one can abandon it entirely.

One can't never start eating and one can't, for practical purposes, abandon it entirely.

So it's a different problem.

You've got a very strong intrinsic push there.

I mean, it's so linked to our survival.

It's a hard goal to manipulate.

I think it's intrinsically just very, very difficult.

We like our freedom.

We like our variety.

I don't want to give up my freedom and variety.

If somebody were to say,

If we eliminated all of these choices, or you're only allowed to shop on Monday, or you're only allowed to buy X calories, it's like rationing in a war, because some people are obese.

Even though I myself have struggled with my weight, I would say, I don't want to live in that world.

I don't want to give up my freedom of choice.

even if it means I and some other people are going to struggle with our weight.
