How we’ fixed’ our diabetic father- and saved their own lives

When their fathers diabetes threatened his life, Ian and Anthony Whitington stepped in with a revolutionary diet and fitness scheme. It was a hard slog, but it worked

When their parent, Geoff, was diagnosed with type 2 diabetes at the age of 50, brethren Ian and Anthony Whitington were not hugely surprised, and for 10 years, they drifted along and watched from the sidelines.

Dad had always been the big human, says Anthony, 39. As children, we thought it was funny. Dad could drink more than anyone, he could eat more than anyone. It was his identity. Thats our daddy and thats what he does.

As we got older, of course we fretted, adds Ian, 37. But everyone around us would say, If he doesnt want to change, you cant change him. He has to do it himself. So nothing much was done and Geoff joined the 3.5 m adults in the UK who manage their diabetes with ever-greater dosages of medication and regular check-ups.

We were all resigned to our family roles, says Anthony. I was a busy fiscal adviser with four kids of my own. Ian was a busy cameraman with jobs all over the world. Dad was a funny fat guy who drank too much.

The wake-up calls were different for both of them. For Anthony, it was a family journey to Chessington zoo in 2013. By then, Geoff weighed 127 kg( 20 stone ), had high blood pressure, atrial fibrillation( abnormal heart rhythm ), plus everything diabetes could throw at him a swollen prostate, poor circulation, ulcers on one foot and a bone deformity on the other.

We were walking around this theme park when the bones collapsed through his foot, says Anthony. I remember him grabbing a railing, the blood in his sock, get him back to the car. Abruptly, this thing that the doctor was managing was very clearly something that wasnt being managed. Dad was insuring people at the foot clinic who had had a limb removed and the average lifespan after amputation for a diabetic is two years. We were losing him.

When Anthony called two brothers to say time was running out, Ian needed no convincing.

The rock bottom for me had been my wedding, says Ian. Dad bided up longer than everyone else he was always the last one in the room, sitting there with a bottle of brandy. I recollect looking at him and “its just” horrendous. He was crumpled. He couldnt get up and dance because of his feet, but he was quite emotional. He said something along the lines of: Ive done my job. Youre my greatest achievement. It was as if that was it. He didnt need to exist any more.

In 2014, when Geoff was 62, his sons stepped in with their own special intervention that included a complete lifestyle overhaul, multiple health consultations, household vacations and heart-to-hearts, pacts, promises and pretty much constant rows. Two year later and 45 kg( seven stone) lighter, Geoff raced through a 100 -mile cycle ride from London to Surrey. He has now been taken off all his diabetes drug as well as his blood pressure pills. He says his sons saved his life and its no exaggeration.

As a professional cameraman, Ian filmed most of the journey, and their documentary, Fixing Dad, aired on BBC2 last summertime. Anthonys wife, Jen, a fitness trainer, co-produced the cinema. Theres also an app for those wishing to do the same, and a book, written by Jen, that includes a dinner and workout program, plus advice on the mental leaps needed to fix a stubborn family member. The fixing terminology couldnt be more apt for a human like Geoff who has expended most of his life fixing things for others.

Everyone described Dad as generous to a fault, says Anthony. Hed pay the parking fines of complete strangers. As children, we ensure him stop the car in the street to chase after muggers. I recollect when my spouse, Jen, was having a bad day after our first child was bear. I was at work so she phoned my papa. We were living in Surrey at the time and Dad said: Ill come over now. Is there anything you need? It turned out he was 100 miles away, but he told Jen he was just down the road.

We owed Dad a lot, Ian agrees. The boys had grown up in Bromley and their parents divorced when they were eight and 10 years old. It changed the dynamic massively. We were with Mum in the week and Dad at the weekend and we got into this pattern of Dad not being able to do enough for us. We didnt miss vacations that richer children were going on because Dad put it on a charge card. If we are trying to do something, he let us. He was spoiling us, really, and by the time we were adults, his debts were so bad, he was a BT engineer in the day and running nights on the Underground and as a security guard. We felt a lot of guilt about that.

So why was Geoff so good at looking after others, but hopeless looking after himself? Perhaps, with busy, grown children, he felt a bit redundant. I think Id reached the point in my life where my children were happy, they had their jobs, they were OK. Id worked all my life, Id done my job and I wasnt needed, says Geoff, who has been married to Marilyn, the sons stepmother, for 20 years.

My wife was going to be the one to suffer if anything did happen to me, but I suppose I didnt devote it much suppose. My life involved working very long hours, which entailed a lot of driving around, and a lot of putting an end to and eating.( His sons assert Geoff couldnt pass a McDonalds without pulling in, and there was always a can of Coke rolling round the floor of his van .)

So what made him agree to this project? Was it to save himself or to please his sons? I suppose a little bit of both, he says. I surely didnt think it could help or change anything I didnt know anyone who had reversed diabetes. As far as the filming part was concerned, I dismissed it, as that was never going to make it on to the TV. It was another of their little projects that was never going to go anywhere! But they asked me to go along with it for a period of time, like a contract, and I agreed.

They kicked off with a roadtrip to the Pyrenees. Dads surrounds werent helping him, so we wanted to get him away from his takeaways, his TV dinners and fridge full of cellophane, says Anthony. The old, fun Dad was vanishing, and we wanted to find that sense of escapade. We get him cooking, cycling, tombstoning. Im not sure jumping into ice-cold water in the Pyrenees in February is the best thing for someone with atrial fibrillation, but Ive never seen him as elated as when he got out of that plunge pool.

While the latter are away, they talked about Geoffs mother a store employee who would do anything for anyone, and who died from septicemia at 69, when her stomach ulcers ran undetected.

It neednt have happened and that upsets me more than anything. I didnt want my sons to feel like that about me, says Geoff. On the last night, they went through photo albums and looked at old household paintings, as well as pictures of his grandchildren. We said: This is all about your family, who dont want you to be dead in two years, says Anthony. We made a pact and Dad promised to commit to this we induced him swear on the only volume he has ever read Shadow the Sheepdog.

Back in the UK, the brothers excavated out Geoffs bike and got him back on it at first with Anthony operating behind pushing him up the hills. After only three weeks, he was at his foot clinic and “theyre saying”, My God, were not having to scrape the ulcers as much. The bloodflow is there what have you been doing ?, says Anthony. That devoted Dad hope. It maintained him going.

Discovering a very low-calorie diet that was having some success in reversing diabetes was another breakthrough. The Diabetes UK-funded survey by Professor Roy Taylor at Newcastle University put patients on an eight-weeks 800 calories per day diet. This was followed by a long-term, low-carb regime, as close monitoring of Geoffs blood sugar levels showed that carbs were causing significant spikes.

It wasnt easy. There were a lot of rows. We were turning our relationship on its head and it got to the part where we were very obviously being the parents and Dad defied that, says Anthony.

It nearly felt like bullying at times, with both of them firing at me together, agrees Geoff. A typical example is early on when the two were coming to Geoffs so he bought a Chinese takeaway. It was a treat and Id tried to pick foods that were compliant, says Geoff.

But hed bought enough for 20 people, says Ian. The whole table was encompassed and so we had a go at him. He wouldnt talk to us for two days!

This, says Ian, is why families are in a stronger stance than health professionals. The route you eat is incredibly emotional and if you criticise someone around food, you can upset them very quickly. You need to get over that a little bit. Households can cross the line and run where professionals are never going to be able to go. We could say things that a doctor could never dream of saying. You cant be nicey-nicey all the time. Youve got to challenge each other. Something wed say to anybody is dont be afraid of that conflict.

When we gratify, they are still bickering over a toffee bonbon that Geoff had feed the previous day while babysitting for Ava, Anthonys seven-year-old daughter.( Ava had a bag full of them .) Ava promptly told her papa. A series of angry messages were exchanged, with Geoff telling Anthony to find another babysitter.( Hes not the finished article, sighs Anthony. But hes in reverse gear .)

Despite the odd slip, everyone appears to be glowing with good health. Anthony and Ian also lost 32 kg( five stone) between them they didnt ask Geoff to do anything they couldnt do themselves while Marilyn has lost 19 kg( three stone ). The couple cycle together, cook together, and they have trenched the takeaways and TV dinners. We sit at the table and eat now and we talk about food, says Geoff. We truly enjoy it.

With the new volume out, the father-and-son squad are about to mentor four new families through a similar health overhaul, and are travelling the world as speakers at medical seminars. Anthony has resigned from his career in finance and Geoff has been able to say goodbye to his punishing night shifts.

And in between this, Geoff is back fixing things again. I just renovated Ians shed, rebuilt the roof and I did Anthonys garage, too. Ive put shelves up for him. Before all this, I couldnt have got on a ladder. It has been the best three years of my life and I just feel terrific.
