Paul was diagnosed with type 2 diabetes 8 months ago and today he’s meeting a world leading expert on the condition, Professor Roy Taylor.

Paul's always been told that his diabetes is incurable and that he would need a lifetime of medication to manage the condition. But Roy's research offers a new hope.
"We've discovered that the cause of type 2 diabetes - fat is really gumming up the works and if we can remove that we can reverse diabetes."
"Type 2 diabetes is a condition where your body's struggles to control your blood sugar levels. This can lead to amputation, blindness, kidney failure and heart disease"

Roy's breakthrough is to discover that the condition is caused by a build up of fat in 2 specific organs - the liver and pancreas.
So he's putting Paul through a MRI scan to find out how much fat he has in those organs.

A colour coded scan reveals how much fat is inside Paul's liver. To be healthy it should be less than 5%. The red dots show the fat.
"These brightly coloured dots show your liver fat to be over 10%. Now that's over twice what it should be. Too much fat in the liver can spread to cause bigger problems."

"Part of what the liver does normally is to pass out fat to the rest of the body. One organ that will take it up is your pancreas."
"The pancreas produces insulin. The hormone that controls our blood sugar levels. It's the fat in the pancreas that stops the insulin producing cells from doing their business. Because they're crowded in by the fat. If we take away the fat, potentially we can do something about it. We can reverse diabetes."

Paul's not worried about his health for his own sake. He want's to be healthy for his wife too.
"I have a desire to live longer. Andrea, my wife, has multiple sclerosis. And it's not getting any easier for her. So, you know, I need to be allowed to look after her. "
In a recent trial using crash diets, Professor Taylor saw nearly half of the volunteers reverse their diabetes after a year. There's no way of knowing whether this will work for Paul. But to stand any chance he needs to stick to the diet.
In my life I've resisted many temptations and hopefully I'm determined enough to resist the temptation to cheat on this diet. Because the only person I will be cheating is myself.

Paul is in Blackpool with his wife Andrea and his grandchildren. Surrounded by the kind of tantalising treats that would test anyone's resolve.
"Have I been a bit grumpy? I have haven't I?"
"You've been a lot grumpy."
Paul is reaching breaking point. Yesterday I did feel quite close to packing it in. "I just felt I'd suffered enough. I was hungry. And I want to look after these without being bad-tempered."
After just 4 weeks, Paul has hit his 2 stone weight-loss target. So, he's returning to Newcastle to find out if that's helping with his diabetes.

He's having a second MRI to look at whether the condition of his liver and pancreas has improved. And Professor Taylor has the results.
Fours weeks ago, Paul's liver contained more than 10% fat. To get his liver back to normal he needs to have cut that by half.

"You can actually see a difference here. So the target's five and this is what we're seeing. 3.9%."
"Oh my goodness"
"You've had a huge change in your liver. Your liver is a new organ. "
In just 4 weeks, Paul has gone from having a liver in critical condition to it being healthy again. But that's only part of the story. Even more crucial is whether the level of fat in his pancreas has come down enough.

"When we started off, the pancreas fat was 8.7%. Now we've gone down from 8.7% to 8%."
"0.7% doesn't seem a great deal."
"That's because a pancreas is entirely different. It's meant to have some fat in there. And that fat's going to stay there. "
It may not seem like much, but one of the biggest discoveries from Roy's research is that just a tiny reduction of fat in the pancreas can correct the cause of diabetes.
"In all our studies over 8 weeks, people lose on average about 1%. And it's that 1% that allows the insulin producing cells to wake up. Now you're well on the way to that."
Paul's results are very encouraging. But he will only be certain if he's finally beaten this killer disease when he goes back to hospital for a full blood sugar test in a month's time.

Paul was recently diagnosed with diabetes. And is facing a lifetime on medication to cope with it. He's about to get the results of a blood sugar test which will tell whether he's beaten his diabetes.
"Shall we have a look?"
"Please. I've been desperate to see it."

"So this is the normal zone. This is the prediabetes zone. And red is diabetes. You're way short of the diabetes zone. Your diabetes has gone into remission."
"Wow! It's worked. It's worked."
"That's the main news of the day. It's good news."
Paul once thought his diabetes was incurable but he's now free from it and if he keeps the weight off he reduces the risk of it ever coming back.

"Freedom! I couldn't quite believe that the dream was going to carry on. And I thought, no, you're going to be that person that doesn't benefit from it. But yes. I've done this for Andrea. So I'll be there for her. And I want to see these grandchildren grow older."
