You must be an ectomorph OP. Superfast metabolic rate. So far for me 2 years on the atkins diet and beautifully well maintained I believe. I was a sugar addict like yourself though I believe worse. About 7 chocolate bars, 2 large bags of crisps, 5 cokes and quarter of a nutella jar per day. Tis non-existent anymore... except the cokes are switched to it's diet versions.
