Oh god, am so fed up. I stuck to Diet Chef last week and registered every calorie I ate with MFP from Mon-Fri. My fitbit told me I had a calorie deficit of 3.5k calories. I relaxed a bit at the weekend, but I didn't relax into ten boxes of chocolates, I didn't go over 2000cals per day.
I'VE PUT ON 4LBS.

Since Friday, 4lbs. I figure, there's either something wrong with my scales, or there's something wrong with me.
And this has now really depressed me, and I'm thinking that I need to drastically drop my calories for the week as nothing else works. Why has this happened and what the hell can I do about it? I really need to get my head in gear, and ideally I need to get 5lbs off asap as it's put me up and over into the next stone up.
