The RDI calculated is based on a calculation and which was in turn based on the measurements taken from several thousand volunteers... Unfortunately people more likely to be overweight will also be more likely to be towards the lower end of the range.
So it's unsurprising it's going to be a bit high for many people on here.
However you can set your RDI yourself on fatsecret.com (you used to be able to do this in the mirror's but I can't find it on fatsecret.co.uk now) by clicking "My fatsecret" then "my Diet" then "Edit your RDI" let it calculate it, then change the number in the box, and hit save.
