I have always been naturally slim, but age and drinking too much wine (a bottle a night - but that is a whole other thread) means I have put on a stone I need to loose. I have cut out the wine during the week but not changed any other aspect of my lifestyle (I eat a normal diet, get some exercise). I have read that a bottle of wine contains approx 600 calories. So, by making this one change, do you think I will loose weight? Currently 9.5 stone and 5'3.
