Hi there. Can anyone tell me if there is a lower weight limit on Rosemary Conley? A relative of mine has been doing this for sometime and we are starting to become concerned. We have worked it out that if they are telling the truth about their current weight, their BMI is now 20.5. Yet they continue to attend class each week and are not at goal, they are very thin and they wear baggy clothes to hide their body.. We have tried to ask questions but they get very defensive. Can anyone that attends their class tell me if this is usual practice please?
