Hello Dotty, I've lost a stone so far but have many more to go than you.
Can I be very blunt with you? I can smell the scent of potential disaster ahead...
only managed to lose half a pound
and you expect to lose 2 stone by Christmas which is 16 weeks.
I think you are setting yourself up for failure - you sound so negative - "only" half a pound? Since when is any weight loss only?! you have had a good week and lost weight and you seem to be frustrated with yourself.
And you will need to lose about 2lb a week EVERY week to lose 2 stone by Xmas! Did you put 2 stone on in 3 months? I'll bet you didn't - why would you expect to lose it faster than you put it on? You should expect to lose between 0-2lbs per week, probably an average of a pound a week after the first month.
IMHO you should be aiming to lose MAX 1.5 stone before Xmas if you lose more great but please please don't set yourself unrealistic targets.
I'm only having a go at you because in my experience (which is VAST in more ways than one ) the most common reason people fail at diets is because they "fail" in their own minds and get discouraged. If you lost even half a pound a week you would be a very happy woman this time next year.
OK lecture over
Nice to have you on board!
