Welcome to week 3 
. This is the week where you have a choice. 
PLEASE READ THIS POST CAREFULLY
If you wish, you can move on to Bootcamp Light, which means that you can now introduce fruit, nuts/seeds, chocolate and alcohol.
SOME.
IN MODERATION.
NOT AT EACH AND EVERY MEAL!
So with fruit, this is mainly berries - check out the fruit counter on the Spreadsheet, which the lovely FinallyHere will be along shortly to link to, which will show you which fruits are best to introduce. Similarly nuts.
With chocolate, make this the highest cocoa content that you can - certainly 70% should be a minimum - and restrict yourself to a couple of square, not a whole bar.
And as to alcohol - it's dry wines and clear spirits, with low calorie mixers or, even better, soda/sparkling water. Your body will choose to use alcohol rather than its fat for energy but some of you have already seen how the disinhibiting effect of alcohol can result in falling into carb consumption 
Remember we're still on Bootcamp - so be very careful how much of any of these you introduce.
However, week 3 (and 4 and sometimes even 5) is infamous as this is the point where you may see your weight loss slow, stop or even reverse 
It's very, very, very common for this to happen, so if it happens to you, don't panic! It's not a stall. It's all about your body settling into this WOE, and what you'll see once we get through the low carb doldrums is your weight loss will continue, albeit at a slower rate of around 1-3lbs a week. (How much you lose will depend on how much you have left to lose).
Bearing this in mind, you may want to stay on strict Bootcamp. There's nothing wrong with this at all - just make sure you are following Bootcamp rules, and that things haven't started to slip and I've seen talk of quite a few slippages . In particular, make sure that you're sticking to rule 4 - i.e. that the majority of your carbs are coming from veg/salad. And don't forget the water! 
Some Bootcampers like to do a hybrid, which means strict Bootcamp during the week, relaxing into Bootcamp Light at the weekend. The choice is entirely yours.
All the best! And remember, if you're not seeing the scales move as quickly as you'd like, then look at the NSVs: looser clothes, better skin, better sleep - and simply no longer being in thrall to carbs
