Hi Malkay
Not sure what your starting point was, but whatever it was I’d say 11lb is considerable. It is a shame the loss isn’t showing in the area you wanted, but as RozyDozy says, our bodies don’t work in a uniform way. I can understand you feeling fed up and frustrated and this is absolutely the place to have a whinge and get it off your chest.
Don’t be too down, you have done well to date and continued weight loss – even slow – is a positive. My suggestion is to be kind to yourself, go away on your break and enjoy it, then come back and start anew. Remember that a big chunk of the battle is mental, so recognise your achievement and focus on the positive.
As for whether you stick with the BSD or swap to the 5:2, it really depends how you feel about it. Maybe a break from the BSD and moving to the 5:2 will help you refocus. But please don’t sabotage your achievement by binging – I’m sure you would regret it.
