Sophie Ratcliffe tried many times to lose weight in secret because she was afraid of being judged or embarrassed.
The mother-of-two hired a personal trainer on the sly and even considered a gastric band operation to try and slim down her 23st 13lb frame.
But nothing worked and it was only when Sophie, 29, from Hayle in Cornwall, joined a slimming club that she finally managed to lose 11st.
