Last year i started the nhs 12 week programme and at the end i lost 2.5 stone. Unfortunately this week in time frame of 3 days a button popped off a pair of jeans and then managed to split another pair. Realised ive let myself go again thought id weigh myself and to my shock i had put back on just short of the 2 stone back on. Feeling very disappointed with myself i am restarting at week one and getting back on track by heading of to the gym this morning. So my starting weight is 11st 13 and at 5ft 2 i have a bmi of 30.5.
