It's really vicious - it makes you feel you've done something today.Tim: How much of your time do you spend thinking about these issues?Brix: What takes up a lot of time for me is combining: you don't mix protein or carbohydrates, so there are a lot of calculations.Jane: Does anyone have an uncomplicated relationship with food?Susie: I have had issues around it, but it was a very long time ago.Jane: So you actually managed to put those issues to rest?Susie: I hope so, yes.Jane: That for me is extraordinary, because I think once you do have issues with food you're going to have them for the rest of your life.Susie: I don't believe that I don't believe it's like being alcoholic. It's become a kind of moral system: a way of assessing whether you are a good person. I used to be so bad when I first came here [from California] that I would carry my own skimmed milk in my bag so I could have a cappuccino with skimmed milk - and it used to drive everyone crazy.Tim: Do you think what you eat has an effect on your mood?Brix and Jane: Absolutely!Jane: At the end of every day, you go over what you've eaten: has it been a good day or a bad day? You are a good person or a bad person depending on that.Tim: This is almost universally reported among women. Look: stir-fried mangetout...Tim: What are the toxic words for you?Brix: Deep-fried.Tim: Is it the amount of fat it involves that makes you nervous?Jane: I worry about carbs: pastry, pasta, bread...Brix: I'm looking at asparagus, lemon juice and oil - but then it's in puff pastry with a lime hollandaise That's just sinful.Tim: Sinful.

That's an interesting word, as though it's about morality.Brix: It's characterised by the feeling that if I've had a good day, it's because I've eaten well.Susie: By which you mean you've eaten according to the set of rules which you have laid down for yourself.Tim: Is that about keeping chaos at bay?Brix: Yes.Susie: So how do you manage a menu like this?Brix: I will have gazpacho and then I will have salad The rocket salad But I won't have the croutons or the bacon That seems safe. I mean, that sounds good on its own, but it's in filo pastry so that's out.. It all starts off good then ends up bad. If I'm in a bad state, I immediately want to throw it up.Tim: Which of these dishes make you go aaaaaargh?Brix: You look at things like Cajun spiced goats' cheese. If I've had a really hard day, if it's been really stressful, I need it. Every time I go out to eat with anybody, it's the same, unless I'm incredibly low - and then I feel I deserve something.

It's a reward.Tim: For what?Brix: No it's not a reward, it's a comfort. Not on a major level but in terms of how fattening it is, and how it's prepared. Now 32, she will shortlybe presenting a new fashion programme. She is always on a dietJane Green: I'm pretty frightened of food really.
