    Okay so at 120kg (32% body fat) decided it was time for action. I’m exactly half way through (day 29 tomorrow). So far averaging about 730 cals a day and down 15 kgs (2st 5lbs). I am increasing my exercise too but want to lose around another 30kg (to get to 8-12% body fat) so will definitely need the 5:2 option. I am not sure how many calories to go to on the ‘normal’ days. I was thinking of a gradual increase say about 100 calories per day each week until I reach say 1600 allowing for exercise and base metabolic rate my calorie intake at my target weight will be about 2300/day. Nearer the weight I can adjust this upwards.

    Thoughts anyone?

    Hi there, the 5;2 doesn’t seem to recommend a calorie allowance just says watch portion sizes but I think the range is something like 1000 to 1200 calories on non fast days and still 800 on fast days. I would also suggest that you get back on with 800 Fast every now and then to speed up your weight loss, unless you are still having steady loss on the 5;2.

    Hi Garvs
    That’s an amazing weight loss – well done. Gradually increasing your calorie allowance every week seems a sensible way of getting back to ‘normal’. As Sunshine-girl says the 5:2 doesn’t specify the number of calories on non-fast days but just says eat normally then 500 calories for men and 600 calories for women on fast days. The BSD suggests eating low carb as a way of life and then cutting calories to 800 on fast days.
    It might be worth checking the recommended body fat% – you know your body best – but 8-12% sounds a bit low.
    Best of luck – you’re doing really well and let us know how you’re getting on.

    I think you may be right, Gattina. Body fat % for men:

    Acceptable: 18-25%
    Fitness: 14-17%
    Athletes: 6-13%
