Hey there
I'm using MyFitnessPal on the iPhone to help me calorie count (its great!). Plus I do three good bouts of cardio a week. I'm under my target of 1400 cals a day most days and since new year I've lost a steady 1.2 kilos a week. Until this week, when I apparently put 4.5 kilos ON.
I had one day over my calorie score (my 40th birthday - I think a girl is entitled to indulge now and again). I haven't noticed any particular water retention, although my rings are a bit tight. My period has started since the shock weight gain, but the kilos aren't tumbling off.
I'm all confused. What do you think?
