As a rule, if you are 9 st and under, average kcal?

Well I'm 8 stone 12 and you are very welcome to view my diary. I am in a tiny deficit now to recomp. My bmr is set to 1522 (which i suspect is too low but just working it all out over the next few weeks) and I add my exercise calories to eat. I am training for triathlon and since measuring with calipers it seems my body fat is probably under 20% .

I was 9 stone 6 for ages, but am leaning up to do a sub 22 5k. This suits me as a motivator rather than just vanity!

I love being this weight. Got curves and muscles and have lost the thickness around my upper thighs and bum. I am in 27 jeans and my legs look leg shaped as opposed to chunky. I am 5'7" and fine boned and narrow.

If I don't exercise the 1522 is kind of disappointingly low. Exercise makes me less hungry yet enables me to eat a lot. I suspect my true bmr is 1650/1700 as I have a kid, and no car, sleep badly, and have a slightly physical job (vocal/music coach).

It's all relative to how active you are in your life. I commute on a London tube train and exercise about 4.5 hours per week, so I do a bit of walking. I am nine stone, nine pounds, and my calories are set at 2000. Myfitnesspal says 1890 for lightly active and 2030 for active. The 2000 a day has helped and then for treats, I have Belvita biscuits on my exercise days, which is lighter than chocolates or digestives, but still sweet. I then have a cheat meal once a month, which is a beef burger with chips or a large pizza at Zizzi's. I've been maintaining now for 6 months. My weight still went down the first few months as I was tweaking calories and losing muscle mass from training a lot less in sport.

Some useful advice here. Thanks for raising.
