I was 76 kg a month ago and want to lose at least 10kg, but I'm not in a hurry. I'm about 74kg now.
Sarah - I am doing it by changing my lifestyle gradually - adding a new 'habit' every week or two:
Week 1 & 2 - concentrating on drinking a pint of water before breakfast and a pint of water at lunchtime, making sure I have at least 5 portions of fruit and veg per day, and eating regularly (every 3-4 hours). In the past I have had times when I've concentrated on each of those separately so felt happy doing all of those - otherwise I would have added just one new 'habit' each week.
Week 3&4 - concentrating on tasting my food and eating more slowly
Week 5&6 - concentrating on drinking a pint of water before supper - that's where I am at the moment.
Week 7&8 - starting some exercise (!) - I don't quite remember what that is...
I'm finding myself eating smaller portion sizes, more fruit and veg, fewer biscuits etc so my eating habits are getting healthier. I am not banning any foods but am reducing carbs - but I'm finding that since I'm drinking more water and lots of vegetables (cooked in tasty ways) I'm not wanting as much of them. I'm so impressed with all of you on the WLS threads - you're doing really well!
