If you want to make the best of yourself, you don't necessarily need to diet - you need to wear the right stuff.
Ottolenghi sells lots of delicious sweet things, but my daily addiction is their unbelievable dark chocolate salted caramel biscuits. They're the best things in the world - I go through half a packet every night. I bring them out after pudding at dinner parties.
I would advise women not to be shy about admitting they've had Botox - it just shows you want to look your best, and there's nothing wrong with that.
