I'm Stacey from Brisbane. I'm 40 years old and weigh 98kgs

I am here for support in losing 20 kgs !
I will be having surgery at the end of the year but have been told my BMI needs to be 25 and currently it's 31 ! Eek !
I'm on Day 4 of my journey. I have changed my eating habits completely, started eating breakfast which I am struggling with. My excercise routine at the moment is just walking daily. My water intake has gone from 0 glasses a day to over 2 ltrs ..... Some days I feel like I am drowning !
Looking forward to sharing my journey with you and would appreciate as many tips as possible !
