I had my first fast yesterday. Didn't eat after 7pm on Monday night, didn't eat yesterday until my 450cal meal at 8pm. This morning I had the gym at 9.30 which I prefer to do fasted anyway other wise i feel sick if I've had breakfast. Didn't eat today until 1pm. I'm planning another fast day tomorrow so won't eat after my tea tonight at about 7pm until my tea at the same time tomorrow. So technically that's doing 5:2 and 16:8 isn't it?
I've put on 10lb over the last 6 weeks (God knows how. I eat well and exercise 5 times a week). I'm getting married in 6 weeks and need to lose some bloat.
I'm also confused as to how many calories I should be eating on NFDs. My TDEE is 1800 cals which seems loads! My food today (lunch, tea and two snacks) adds up to 1200 and it's loads of food.
With your statistics, 1800 should be fine for NFDs. Do NOT aim for BMR on 5:2 The FDs are what provide othe calorie deficit to lose weight; the NFDs are to keep this deficit, hence within TDEE. Don't try to force more of a defeicit on NFDs too, or the WOE will not be sustainable.
On NFDs, don't eat junk to come up to TDEE - many better iptions
