I have a friend and coworker who is overweight. She has indicated a few times in the past that she is starting a diet. . . . it often doesn't last long. Yesterday, she indicated again that she was starting a diet and asked if I would remind her of that whenever I see her with unhealthy foods. Ok, no problem. Based on her prior attempts, I suggested maybe just making more conscious, healthy food choices than tying herself to a diet. When I make a yummy, healthful meal I will email her the recipe sometimes saying how good and easy it was to make.
I invited her to park further away in the parking lot with me in the morning to get a little walking in and offered to walk with her at lunch (which she declined because she doesn't like the sun)
Is there anything else you can suggest to be encouraging in her endeavor? I think it would be great for her to be able to stick with her plan.
