A 32-year-old mum, from Bristol, tipped the scales at 23 stone, and decided to shed 13 stone when her son questioned why her belly was so much bigger than other mothers he had seen around school.

From the shame and embarrassment, Agnieszka Roguska, was driven to lose the weight in one year after following a strict diet and regular exercises.

Agnieszka's eating woes began after she gave birth to her first child Oliver at 27 weeks gestation – more than three months early – and during this traumatic period she spent most of her time at a neonatal intensive care unit.

Speaking of Oliver, now aged eight, she said: "His prognosis was not good and his stay in NICU took a huge emotional toll upon me. I did not have the time or capacity to think or look after myself and this was when I began to put weight on.”

She began comfort eating, snacking on crisps, chips and indulging in super size meals.

"I remembered facing this same situation when I was a child as my mum was bigger than other mums were," continued Agnieszka.

“When I was a teenager, I remember other mums looking pretty and wearing nice clothes when my mum was hiding in the house from others with her weight problem.

“At that time I promised myself that I will never be like my mum, I wanted to be that pretty mum in nice clothes that he could be proud of."
