Hi my names alex cooke, I started my journey depressed and no self confidence having put on near enough 4 and half stone in 2 ish years. I have quit sugar and anyhing processed. And prepping my meals everyday and cooking everything fresh. I have also been Wright training with a PT 5 times a week along with thai boxing and just started yoga. I have been eating more than ever just the right stuff now . But mentally I still feel huge! Need encouragement if in honest and friends who want the same as I get no support from home.
