Hi cherry every week has been 100 percent except the week i lost 2lb which i was naughty and had buffet food (was at a wedding and felt light headed so had to eat as was driving and there was sandwiches or fried stuff so opted for sandwiches)
When is your first weigh in? If you stick to it and drink the water any loss is possible although 1st weigh in is always more generally because its flushing out all the rubbish
