As we move into week 2, one of the rules that is relaxed is rule one - i.e. that you must eat three meals a day. The reason for insisting in Bootcamp that you do that is to ensure that we have stabilised our blood sugar levels and, hopefully, you are no longer feeling so hungry, and much less need to snack between meals. (You may also find that you have been struggling to eat sometimes - bet you never thought that would happen on a diet!)
With this in mind, you may consider missing breakfast - it's often a meal people struggle with. There's a lot of interesting stuff going on at the moment about fasting - intermittent fasting or 5:2 eating.

The combination of low carbing with intermittent fasting could be a very potent one, given that low carbing controls our appetite/hunger levels.
Personally, I find it much easier to miss breakfast than to try and do the calorie-controlled days (two days at 500 calories). I tried the latter before Christmas, when the first 5:2 thread started here. I realised pretty quickly that it wasn't for me, because instead of enjoying the 'eat anything you like' days, I started obsessing about how many calories I was eating/could eat/had left for the day. I have vowed never to do that to myself again, so decided 5:2 probably wasn't for me. Also, the great joy of this WOE, IMVHO, is being able to relax and simply enjoy good food.
Anyway - have a read and see what you think.
