According to an online calculator my BMR is 1330 calories. I exercise (5 weekly hours of cardio, according to my Garmin that was around 3100 calories). My total calorie intake last week was 11,400 calories. According to some BBC calculator I need 1600 to maintain (not taking exercise into account), which is 11200 a week.
So I have around 3000 calorie deficit, but no change week.on week. I'm not that bothered, but I would have expected to have moved by at least 100g!
