I am very much over weight. I am 44 years. I have tried many diet plan but failed maximum after 3 weeks. My weight increase very fast and I do not have thyroid problem. I am not junk food lover but occassionaly I take. Being over weight my knees pain after I walk even with slow speed. So skipping and aerobics as mentioned by you will be difficult for me. So can this diet plan still work on me?
