Your english pen-friend has written to you saying he wants to get fit and lose weight. write back (50 words) giving your advice

Dear Pete,
Thank you for your letter. It is great to hear you want to get fit and lose weight.
You write that you want to keep to a diet, but you should be careful. Eat a lot of vegetables. You should stop eating junk food. Also avoid eating sugary and fatty food. Do not forget to drink water.
It is very good that you like swimming. You can also take long walks  every day. You should sleep not less than 8 hours.
Please write to me about your progress.
Best wishes,
