I have gained all my weight back after my surgery, I need to know how to get myself back on the diet to lose weight, I just purchased protein shakes, but I have nothing to help me with a starting point to begin to lose this weight. I have had several surgeries since 2012 on my back and my knee and elbow so things have been quite stressful. I am taking all my vitamins, plus extra B, but still losing hair. I am extremely frustrated.
