Is it 500 calories for everyone, and how much on a NFD?

[deadduck]

I am finding the "500 calories for women" (i.e., ALL women) somewhat hard to believe - does this not depend on your size/age etc? I'm thinking that 2000 calories for me is too much (5.5, in my mid-forties). So if I feel that I should have no more than 1600 calories (kind of based on past experience), would that mean that I should not exceed 400 calories? Is there a scientific way to determine this? Do you all rigidly stick to 500 calories?

Use this. I can only have 400 cals on a FD

Oh dear Lord. 381 for me. That is impossible .

Thank you.

412 if i put in light activity. 487 for moderate. I will do a longer dog walk on fast days from now on.

500 is easier, more sustainable and saner

Think of it less "per day" than "per week"

Monday = 500
Tuesday = TDEE less 10% - so around 1400
Wednesday = ditto
Thursday = 500
Friday = TDEE - so a bit over 1500
Saturday = yes, well, don't ask
Sunday = TDEE

500 works in practice for all sizes of women. The scientists who invented 5:2 and ADF all say go for 500
