Five years ago I made a vow - to WI daily or almost daily and record it on Fridgegraph and for the weight I was that day to be my highest ever. I did it!
Previously I often started a new diet shocked by the figure on the scales at yet another 'highest ever' weight - so I have stopped that.
I haven't stopped yo yo dieting though. I haven't stopped being overweight or obese. Why? Because I haven't started being fully accountable and aware of what I consume all the time (not just when on a diet). I lose weight follow all kind of rules but cannot sustain them long term.
So I have started using MFP (Love the barcode scanner!). I've set my target Kcals as the amount it take to maintain my current weight (just over 2000 Kcals) but, as I want to lose weight, I aim each day to eat 1500 kcals - and that is what I have just started doing (first few days I simply recorded/slowly cut down). I don't set it to that amount though as it things slip up a bit then it is NOT the end of the world - I have broken no diet!
Anyway, this diary is not for recording what I eat. It is just for offloading other stuff - thoughts, inspiration, NSV, projections...
