Within a year he had lost around 15 stone.
However, Jack admits the operation alone was not enough and says the biggest changes came when he began educating himself about nutrition and exercise.
By 2024 he had reduced his weight to around 27 stone and decided to take his fitness journey even further.
He added: “I thought to myself, I’ve come this far, let’s see how far I can take it.”
