Oh that's great advice thanks Bagpuss - but why the painkillers? Great first week's loss too hun, well done. Hilarious that it's all marketing at the end of the day eh?
I'm mostly worried about being constantly HUNGRY so have ordered shiritake noodles and glucomannan capsules to fill me up so I don't turn into an evil snarling b*tch - at least, no more than usual

. Also going to add low cal veg to the evening meals so I keep my greens up.
Headaches! I get them at the drop of a hat anyway, but it's not an unknown side effect of adapting to ketosis. And for a while, as your body adapts to it's new fuel source it can temporarily cause things, like hydration, to be out of kilter.
The low cal (or more importantly, low carb) veg is a good idea. Sometimes the VLCD meals can go through me a bit to start with (sorry, TMI, but true) so a bit of bulking out helps. Also, given that it has been shown that there is no additional benefit to dropping below 800 cals there is leeway.
And as for the hunger, that's an interesting one. That's the 'hard but worth it for the results' bit. And interestingly, there are several aspects to it. The not eating ' physiological hunger' comes and goes, and is variable - believe it or not it's the easier bit, and lessens a lot with time. There are ways to distract yourself from it until the next meal. Then there is the cravings, your body crying out, withdrawal like, for easy carbs and glucose that you've fed it on for years which isn't hunger per se, but for me is the hardest bit. I could chew a door right now but it's not stomach hunger, which is why I have spent a lot of time on the net this past few days. This also passes, but is the bit that tends to cause people to wave the little white flag early. Therefore it's interesting to work out for yourself which one you're experiencing, as you deal with them in different ways.
Also, I'm a bit fuzzy headed and have been cold, also known 'first week' 'getting used to it' side effects, which had better subside soon as they'll start making my job, which I go back to tomorrow, a bit of a damn challenge. but by 8am tomorrow I'll have bigger things to worry about...
