Tobee definitely! I have started 3 rounds now, although 2 and 3 have not been as strict, but I have never achieved that totally on it feeling as with my first round. I just don't seem to manage on 800 calories and as a result have never got beyond the first week of detox before cracking, which means I am permanently in the throes of week 1. So get good losses, but big gains, and all the fun of detox over and over.
This might be just me though^^
I'm currently reading Fat Chance and off the back of it I'm going to design my own 'version' for when o get back from my holidays as there's things in there that are more relevant to me (but might not be to others)- but basically I need to be strict. The first round I didn't drink a drop either, which must have helped and had a tiny babe in arms who was sweet and cooperative rather than this 2ft tall dictator who seems hell bent on destroying my sanity (is it really only day two of the holidays? Really?)
Every time I read the BSD book I realise that I am not wholly doing the plan- I cheat, I drink too much at weekends!, I eat more fruit, I have more days where I don't count than do, and I rarely exercise beyond school runs and general toddler herding. I did this in round one too, but I think my fat has gotten wise to my antics now, and stays put rather than melts away regardless.
Fwiw, I wish above all else that I had continued after round one immediately, rather than had a break and returned because I reckon another 4 weeks would have made a big difference and instead I'm still the same weight a year later and I've been 'dieting' since then! No guarantees that I wouldn't have regained in maintenance, but at least I might have got there to start with IYSWIM.
Oooooh I am a right fun Bobby today aren't I!!?
