I want to lose a bit, not much, about a stone. Basically my weight fluctuates and at the moment it is at the top of where I feel comfortable. Weight loss for me (snd believe me I have lost plenty, formerly a 21 stone lady, down to 10 stone, currently 12 stone, want to be 11 stone) works on 1200 calories a day. So I am not working out TDEE etc as I KNOW 1200 does the trick. But to stick to 1200 with two days of 500 is too low.
So with 5:2. I not seeking to reduce overall intake but to try to get any potential health benefits and to make it easier to stick to an overall average 1200 taken over a week.
I am eating 500 +/- 70 on my fast days. On a 1200 a day diet, that gives me a weekly deficit of 700 X 2 = 1400 So on my non-fast days, I have 1400 to be divided out. So my intake can be 1200 + approx 250-300 = approx 1500 cal a day. (I did calculate TDEE and it is around the 1900 mark)
Does that sound right?? I could stick to 1200 on non-fast days but my feeling is that I shoudn't!
