Who me? Nah! Never took a break from SS'ing in my life
Seriously, though - I had about 5 or 6 'mini' breaks throughout my time on CD (if you don't know I lost over 8 stone in just over 9 months, reaching my target weight early December last year). Each time I sole sourced right up until I went away and made a very conscious decision to recommence SS'ing the very moment I got home again - which I stuck to religiously when I was at home.
When I was away I replaced at least one meal a day with a CD tetra or bar and stuck to protein and veg/salads only for the other meals - no carbs at all - and minimal alcohol (none if you can avoid it). Each time I put on between 3 to 6 lbs depending on how long I was away, which I lost within the first week of sole sourcing again - so I reckon each break I took put me back a week from reaching my goal.
Everyone has their own opinions about the merits (or otherwise) of taking breaks when on a VLCD, and as a CDC my advice to my clients now is: It's best to avoid taking a break if at all possible. However - sometimes 'life' gets in the way of dieting as we all know, and part of the whole re-education/ re-feeding process is learning about our relationship to food and what we should/shouldn't be eating once we've reached our goal weight and go into the stabilisation phase to maintain the loss.
Speaking strictly for myself, I found my breaks taught me that I was able to control the food I ate which I think has helped me now I'm at the maintenance stage as the 'fear of food' was lessened in the process. As of today I'm only 3 lbs
heavier than I was at my lowest-ever weight.
I hope this helps you decide what to do - but, most importantly, enjoy your holiday in Disneyworld
