Bus driver Iain McLeod of dundee, who was once described as morbidly obese has shed half his body weight.
He once weighed 25st 12lbs after surviving on a constant diet of cheese sandwiches, pasta, packets of crisps and sugary drinks.
His weight spiralled out of control as the result of his high-carb diet and got even worse when he gave up drinking and kicked his drug addiction four years ago.
But the 32-year-old decided enough was enough when he went to get fitted for a new work uniform and was told he would need 50-inch waist trousers and a 4XL top.
Now Iain, who has adopted a vegan diet, has slimmed down to 13st.
The father-of-two is half the man he used to be, now wearing medium sized T-shirts, and has taken more than 16 inches off his waist.
He said: “I have been up and down with my weight my whole life.
“But when I almost reached 26st I knew there was an underlying issue that I had to deal with.
“The doctor told me I would be lucky to last another 10 years if I didn’t lose the weight. He just said if you keep going you won’t make it – I was killing myself.
Now Iain starts his day with porridge, has a salad for lunch and eats a whopping 15 portions of fruit and veg a day.
The impressive dad, who has lost the weight without any help, hits the gym three days a week after years of doing no exercise.
He said: “After 8pm I don’t eat at all, even if I am working a late shift, I am in a routine with it now.
“Before, I didn’t even eat any fruit or veg, and I didn’t exercise at all, but now I eat between 10 and 15 portions and go to the gym at least three times a week and work out at home.
“If you want something bad enough you won’t make excuses, you’ll find a way to fit it in.”
