British R&B star Jay Sean has struggled with his weight since he was a child - he shed the pounds with an obsessive diet as a teenager and has refused to compromise his gruelling eating regime ever since.
The 26 year old admits he was a "very, very fat kid" and only took steps to slim down when he left home to attend medical college.
Sean cut carbohydrates, such as bread and pasta, from his diet, and embarked on daily workouts to lose the weight.
He says, "(I was) a very, very fat kid. I was 14 stone when I left school. I challenged myself. I used to look at pictures in magazines and go, 'I wish I had a body like that.' And I said to myself, 'One day I will look like that. I will get that body.' And I worked my a**e off to get it. I lost three stone over the summer, people didn't recognise me."
The singer also insists he will never deviate from his eating regime, because he's scared the pounds will pile back on.
He adds, "Even if I'm twisted out of my head (drunk) and go for a kebab, I'll order the meat and chuck the bread straight away. I'm so focused on some areas of my life that I just won't allow myself to veer off that path."
