@plantlover - on holiday it depends! Earlier this year I was in Oz, and I ate what I wanted, which included carby stuff. I knew it would result in weight gain, but that was fine. It was the downside of 'relaxing'.
When I got back, I went straight on the wagon, and also re-introduced 16:8 (essentially just missing breakfast). I also had a 10 day alcohol-free period. (It should have been the whole of February but I was crap
).
It's entirely up to you how you manage things - but if all you do when you're away, or when Bootcamp is finished, is go back to your former high carb way of eating, then you will put weight on.
You need to find out how many carbs, on a daily basis, you can tolerate. The only way to do that is to experiment. Once you get to your desired weight, gradually introduce more carbs, until you start to put weight on again.
