Hi,
This is offical CD guidance:
The ‘Sole Source’ programme should not be followed for
one week preceding blood donation and for one week
after. In fact, a centre will refuse to take blood if
they know the donor is on a very low calorie diet,
because blood viscosity and volume are affected by the
‘Sole Source’ programme.
