I find it best to keep it to myself, especially if the much needed support is not there.
It must be the exercise your doing which is speeding your loss up, as I lost 11lbs with no exercise and only 3-4 shakes a day and no meal so it is sad to read how you were disheartned.
Inevitably your losses are going to vary each week, but its best not to try and rush it and to hope for too much and then become dissapointed a loss is a loss, be it 1lb or 11lb, it all adds up to a slimmer and healthier individual. Well done, good luck, and keep going.
We can do it!!
