Hi all and thanks for all the responses...
just a little update.
After my initial post I decided to follow some advice and start tracking all consumption and exercise on myfitnesspal. The following weeks my wife has lost weight now, so it must have been down to nutrition mistakes or just a small blip

We are just finishing our recovery week and at our weigh in last sunday my wife has lost 12.6lb since we started and I have lost 10lb so we are doing great now! We are both very pleased with our results so far...
I do however have another question...
Should I be increasing our calorie intake as we go into month 2?
any advice on this would be really appreciated!
Regards
Bradley
