YES! This is what Im going through at the moment. Friday all i wanted was pizza, So I did. tbf it was an asda good for you pizza. so not as bad as ordering in but still it was 27 syns in that alone.
Im finding it hard to resist chocolate so have been having the 2 finger kit kats as theyre the lowest syn in choccy I think.
I think the best advice is, give your body what it wants but in moderation and aslong as its not going to put you in the "oh well ive been bad today might aswell have a bad week" mindset it should be fine
