To really adopt him as their main kind of model, you need to have a really good, perfect image.

And he is really one of the most well-beloved figure here, despite this single scandal.

Could offering smaller, cheaper portion sizes in restaurants help tackle obesity?

That's the recommendation from the head of the British government's obesity programme, Professor Navid Sattar.

Women, on average, need fewer calories than men, and Professor Sattar says they and others could benefit from the availability of alternative options.

Not just women, anybody who wants a smaller portion.

So that could be smaller men.

It could be, for example, if you go out with a family, children.

But it was prompted by the fact that actually obesity levels are higher in women in nearly every part of the world now or many of the super regions of the world.

They're also higher in more people who are from deprived communities who tend to be shorter.

So people who are smaller, generally women more than men, people from less affluent versus more affluent are shorter.

Therefore, they need less energy for their body's requirements.

And if we offer single portion sizes, which are really to fulfill the requirements of average men, we're nudging gradually and progressively nudging more and more people to eat more than they need.

And that is contributing to widening obesity disparities.

Clearly, costs should be proportioned to the volume of food.

I mean, if you're getting 75%, I suppose the cost should be 75% of the 100% cost.

So the issue, of course, then means that places that make food or make various products, probably their profit margin might be somewhat less.
