Is there a way to stop people from talking to me about their diet?

Anonymous
I'm quite thin and in no need of a diet. I can't help but wonder if my coworker thinks I must know something they don't.
I am SO SICK AND TIRED of hearing about their diet, their exercises and their salads and now they mimic how often I snack through the day and it's made me really self conscious, especially when they ask me what I'm eating and offer suggestions. They're always telling me what's healthy and won't shut up. I eat healthy but they're just way overly excited. I'm glad they are getting healthy but it has nothing to do with me and I'm sick of being examined by them.

What can I say to them to give them the hint without them getting mad? I am so sick of being reminded every day, all day, about their diet.
