Biggest enemy in my diet is laziness

Just weighed myself. Shocking 57kg.
I have been very lazy lately. Too lazy to cook. As a result, I have been stuffing myself with junk food such as pizza, chicken burger and ,..yes...battered chips. Battered chips are the worst. However they are .... yummy i know.
I have nt been doing pilates for quite a while. Laziness. I notice my belly is growing a bit now.
Need to get back on diet track and back into shape..
