Well done on a good weight loss George!
I'm sure I remember reading somewhere that the second week of a diet is one of the toughest as far as weight loss goes. Something do do with the body reacting to having had less food the first week and so trying to 'stockpile' everything it can eg. fat etc. Not sure if this is def true but it makes sense to me.
You carry on doing what yr doing hon, u seem to be really enjoying it and its obviously working! Best wishes for a great week 3 xx
