My DP and I started this a week ago. I need to lose about 6 stone to be in my ideal range, and he needs to lose about 3. He reckons he lost 2-3 stone using this diet before, and after one week he's already lost 3 kilos! I have only lost .5 of a kilo, but it's better than going up I guess!
This diet is essentially similar to Atkins, though you aren't supposed to go into ketosis, and the daily carb allowance is 2-3 times higher (40g, 60g at absolute most). I'm finding it fairly easy to do, and I'm not hungry, but I am TIRED and think am a bit constipated (TMI?).
