I kinda feel for you. If you have enough money to spare also buy the 80 10 10 diet by Dr. Doug Graham, its a book promoting the fruitarian diet that MH also believes in..
he will get enough protein from nuts and seeds..
most of the people who have had success on 80 10 10 are athletes (thriathlon winners, marathoners and cyclers)...search them on youtube and ask your husband to watch them
theFruitarian - thriathlete
durianrider - cyclist
liferegnerator - body builder
I know being in the military is almost like being an athlete in terms of the physical and mental requirements.. he will thrive on this diet..
