Right. I’m at the airport with free WiFi and a pretty much fully-charged iPad, so here goes ...
First @Twoo apologies if you thought I was accusing you (or anyone else) of lying, my post was a bit off the cuff, but does reflect the fact that over the years I’ve been running Bootcamps it has become very predictable that people will post complaining that they haven’t lost anything, insist that they've followed the rules, but when pressed will confess to 'just one' cake or chocolate or glass of wine, etc. You get the picture. This WOE isn’t a forgiving one, and if you cheat, it won’t work.
I'm not saying that applies to you @Twoo! This was a general comment/question, but particularly in relation to posts made by @RuffleBelly and @farine.
However, and this is really important for all of us:
WE HAVE ONLY JUST STARTED WEEK 3!
Please don’t get despondent if you haven’t lost as much as other people. It's not a competition. Everyone loses differently.
And has already been said many times on these threads, it’s not always about the number on the scales. Have you measured yourself? Have you been trying on clothes that were initially a bit small or tight?
If you haven’t seen a loss, or have seen a gain, you need to ask yourself:
Have I really followed the rules?
Have I eaten plenty of fat - really?
Have I drunk the water?
If you can, hand on heart, say yes to the above, then:
Are you eating a lot of dairy?
Are you snacking between meals?
Are your portion sizes too large?
Are you on any kind of medication? (even ibuprofen)
Are you fairly near your target, with not that much to lose?
Have you been a serial dieter? Switching from one diet to another can mean that it takes a bit of time for your body to 'trust' you!
And if you really have been doing everything perfectly and still aren’t seeing the scales move or the inches go, just ask yourself this:
Are you enjoying the food?
Do you feel deprived?
Does it feel like you’re on a diet?
What would it be like if you went back to calorie counting?
What would it be like it you went back to low fat?
Ultimately it’s your decision whether you want to continue. I can’t make it work for you. I’d be a millionaire if I could 
But I’ll help as much as I can, but just be realistic and patient. Hundreds of other Bootcampers will tell you that it works if you stick with it,
