Hi Kevin,
We are a rare breed. . .guys that actually want to gain weight!
I also have difficulty gaining muscle. I'm not sure how much of a role diabetes plays in mine. I have other issues.
I recently read a book from Men's Health, "The Testosterone Advantage Plan". Although it doesn't specifically adress diabetes, it does give good tips on diet and exercise. The concept is based on maximizing testosterone for fat loss and muscle gain.
The book makes points about what to eat, when to eat, how much to eat, when to exercise and how. I have not followed the plan to the letter. I have, however, begun to practice some of the principles. I have seen some gains.
My biggest obstacle is time. At present I am the only source of income at my house. I have a full time job, a part-time business and a part-time consulting/sales job. However, the things I learned from the book and Men's Health magazine have helped me fit workouts into my schedule. The gains I have seen have helped to keep me motivated.
Maybe we need to journal our experiences and collaborate on a book.
