One of the things that people often ask me is, well, how has your diet changed since you started Zoe?

And the answer is it's changed a lot.

And one of the biggest ways it's changed is that I now eat a lot more fat than I did.

I was absolutely sure that fat was bad for me five years ago.

My dad was basically put on very low fat diet because he was told he had very high cholesterol in his thirties.

So this is now sort of

40, 45 years ago.

And so that means that at home, we ate this very low fat diet.

As a result, we of course ate lots of carbohydrates because that's what you do to fill it in.

And of course, lots of refined carbohydrates, pasta and bread and things like this.

So I then did these ZOE tests and it turns out that actually my blood sugar control was really quite bad and actually my blood fat control was much better.

And so that's what the advice is pushing.

But I still feel really guilty when I eat cheese.

Like it's even though I've seen this and I also have noticed the way that actually my hunger is lower when I'm eating these high fat foods.

Like I still have this basic feeling that it's a bit naughty, isn't it?

Like it's not the right thing to do.

What are your thoughts on that, Sarah?

And can you say what sort of foods those are, Sarah, just for those of us who don't think about things in this chemical way?

And despite the fact that actually basically the cheese comes from the butter, right, Sarah?

So that's like even more surprising.
