More info needed for approval with MTF any idea's???

So I called Tricare and they said Fort Gordon MTF needs more info to approve the VSG for me like 6 months of documented attempts at: diets, meds and excercise. So the doctor can take care of meds, I have my weight watchers receipts with weigh-ins and a reciept for a gym membership. Do you think the receipt and weigh-in from WW is enough or do I need to give them my food journals as well? Also before I joined the gym (only did 3 months there) found it to be a waste of money since I worked out at home and with friends. Would my workout journal be enough? Any help would be great as I have an appt. wed. oct 26th to go over these things with my pcm.
