I think we all feel insecure about how we look every now and then, ladies especially. My fiancé also has knee problems, where it pops in and out of the socket willy-nilly. But since he lost weight the problem has gone down significantly, so you are on the right path! He also started his weight loss by walking and counting calories. It worked for him, so as long as you stay positive and stick with it, it will work for you! Good luck!!
