This is a constant complaint of clients who get in touch with me. Why on earth do I persist in eating even when I am not hungry?

A current telly advert is encouraging a Good Mother to feed her family even though they have said they are not hungry. Sometimes I despair! It is hard enough managing our eating when we are accosted every day with little encouragements to eat, little cues that trigger our eating - ads in the paper (even in slimming mags), ads on the telly, so many food shops and so many takeaways. We are affected more than we realise by these constant hints to eat.

So the latest advert by Galloway cheese has me shouting at the telly. The family is at home and the Good Mother asks if they are hungry. No, they are not. They are all busy doing their thing, enjoying themselves and not thinking about food. So the Good Mother decides We will see about that, and fills a dish with nachos or crisps, grates on a cheesy topping and brings it to them, fragrant and melting. Well, I was right, she suggests, you were hungry. Well, not until the food was stuck in front of them they weren't.

Most of us don't put on weight by eating 3 meals a day. It is the fun snacks like this that make us fat. So we don't need advertisers to do more of what is not in our best interests.

Well, after that rant I feel much better.
