You are most welcome Jim, keep up the great attitude my friend.
When you talk to your nutritionist have them look at Dr. Layne Norton's, PhD in Nutritional Science out of the University of Illinois, research on keeping lean body mass on a calorie restricted diet. He uses it for getting into competitive shape when cutting as he's a bodybuilder and powerlifter, however the principles will work in cancer treatment as well due to how limited our intake becomes in treatment.
Here's a link you can share, very comprehensive.
