When I developed my own weight-loss program a few years ago (losing 88 lbs. over a period of 14 months), a significant part of my research took me to the Mayo Clinic website and resources. I checked my choices and tailored my plan in a way that would work for me, as rapidly as feasible, and not be excessiely stressful to my body. Using the Mayo website helped me keep my plan in a healthy range. I still go there to stay current now that I am on maintenance.
I don’t often recommend cookbooks, there are so many. But the Mayo Clinic has several cookbooks and diet books I love, and I think you will too.
