Cutler's program is not intended for weight loss, and is not a cureall for issues caused by the person's other choices as far as diet and supplements. That practitioner you saw who was overweight and had joint problems could have a bad diet or other issues, and yet be free of toxic metals due to Cutler's protocol - perhaps, so please don't discard an entire approach due to symptoms you see in someone that can easily be caused by other problems.
