First off, she's talking crap because fresh food is not as expensive as she makes out in the UK. I love doing grilled Chicken with grilled tomatoes and potato salad or a stir-fry.
I would say that buying fish is expensive and we do it grilled or steamed.
1) I spot at least 2 bottles of Lyne's Syrup
2) Pop Tarts are really bad, I tried them once and realised how bad they are
3) The Cadbury Heroes in a tin are like £5
4) What she doing with Iced Lemon cakes from TESCO, Cadbury Fingers, Caramel Bars (bottom-right) & the Barney Chocolates
It's no wonder why she's so fat...
My local gym is £18 per month and my Sister's better gym is like £50 for swimming, gym, 1-1 classes, group classes, etc, and if she can't afford the gym, she can do running / jogging, star jumps or cycle or running up and down the stairs.
She could work in TESCO on till and get discount to save money on food and work her way to being off benefits.
