| Hi Mark,
Welcome to the group. It is a great place to ask, learn and get support.
Don't worry, if you are diagnosed with the big D, it sure isn't the end of the world. You will learn to shift your preferences for comfort foods to different comfort foods that are better for you. You won't have to eat only small portions if you learn to eat the right stuff. It helps that you are fit and active, you are starting well.
You won't have to give up pasta if Dreamfields works for you. For many of us, it prevents a spike in blood sugar.
Keep us posted.
