Recently, after many months of committed effort and losing a significant amount of weight, I "hit the wall." Those of us who have struggled to leave the ranks of the obese know about "the wall." The wall is when weight loss slows down and we hit the famous "plateau", and your body is thinking it over. Should I coninue to let go of stored fat or hold on tight to my stores of reserve? I believe the physiological aspects of weight loss need to be better understood in our conversations about obesity.
