Mum-of-three Lorraine O’Loughlin decided it was time to slim down after she fell into a deep depression and rarely left the house.

The 28-year-old found herself stuck in a rut, skipping meals in the day and then binging on crisps and chocolate throughout the night, until her weight soared to 19st.

Suffering from insomnia, Lorraine was often awake all night and then had to rely on 15 cups of coffee to keep her going the next day – each one with three sugars.
