The Programme, final week: Sarah's comments

I'm quite sad it's all over. I have learnt so much about food and nutrition. My body shape has changed and my complexion has improved – with previous health regimes it's taken three to four months to see an improvement but this has made a difference in four weeks.

I thought the exercise would be really difficult and it was to start with, but it's become part of my routine now. I'm really pleased. At the moment my goal is to increase my runs to 30 minutes, and I might take up tennis again.

The original incentive to do well was that people could see my progress in print, but working with Matt and Lynne has been an amazing experience in itself. I feel so privileged to have had the luxury of such encouragement and expertise. I'm looking forward to retoxing, within reason. I was in the habit of drinking every evening and won't get back into that, but if I fancy a drink I'll have one. I'm also looking forward to eating chocolate.

I'm going out for dinner tomorrow night – my first proper meal out since Christmas. I'm already thinking about what to choose.
