Week three down...

Hi folks,
So week three is over and 0.5lb on this week, very very disappointed and upset. Have been on plan and been trying really hard. Even had sit at dinner with friends yesterday and see them eat bbq ribs and chips while i had a skinless, fatless chicken breast, jacket potato with no butter and salad and they thought I was crazy eating what I was! But I am also pre menstrual so hoping that is it! :'(
Still gonna keep trying just a little sad x
