I tried a variation of the F2 diet before Christmas, with a bit of success (now all put back on over Christmas)
But I found that a highish carb diet drastically improved my sleep and I def felt better. I have been trying to lose weight low carbing for ages but I have consistently gained weight. I don't think low carbing is for me, I understand the low fat, high fibre stuff better, and it's the way I managed my weight years back when I was slim.
Anyone want to join in a GI / high fibre type diet?
