I am on my third day. Yesterday I know my dear wife was concerned, but I am just not hungry. Around noon, my wife brought me a small plate of blueberries, beef jerky, walnuts,and a strawberry. They were very small portions, and I did eat them. She said I should eat like this 3 or 4 times a day. But i don't think that is grazing right? Around 5 o'clock I was hungry, and I am even trying to cut back on portions during supper All three days I have got out in this heat and walked a good hour. I noticed I had some color in my face, and I feel really good. We are getting a threadmill today, and that will help get my heart rate up. I am determined and focused, and my wife is even cutting back. I don't see any harm in not eating if i am not hungry. If i was hungry I would graze something.
