Top cancer doctor reveals: Why A LOT of what you fancy does you good!

We’ve heard it so many times before. The route to a healthy life is abstinence.

Turning down that second glass of wine, nibbling on a celery stick, choosing the green salad instead of the chips, obsessively protecting ourselves from every single UV ray emitted by the sun — the list goes on and on.

There can’t be many of us who haven’t thought at some point, ‘Enough! No red meat, no wine, no sun? It’s too much! What sort of a life is that?’ But now the person expounding this view is Professor David Khayat, one of the world’s most eminent oncologists and former chairman of France’s National Cancer Institute. Among his many accolades, he initiated a charter that changed the way in which cancer, cancer research and cancer patients were treated around the world — including here in the UK. In 2006 we awarded him a CBE for his efforts.

Now he’s determined to speak out against the cult of fasting, fitness regimes and self-denial. It’s his strong belief that this sort of miserable deprivation needs to stop.

‘Life is a gift,’ he tells me in his accented, but excellent, English when we speak on the phone — him in Paris, me in London. ‘You have to honour it by finding joy and happiness. What is the meaning of living if the time between birth and death is just spent with no memories?’

And the memories he encourages you to make include convivial lunches with friends, where nobody worries about how much they’re eating or drinking, lazy afternoons of lovemaking, days strolling in the sun, and he’s written about it all in his new book, Arrêtez De Vous Priver — Stop Depriving Yourself! It is a manifesto for ‘hedonism, joy, conviviality, love and friendship. The pleasures of life. The things that give our lives colour and value’.

And as we prepare to return to a normal(ish) life, this sort of liberation is, surely, exactly what we all need to hear.

Of course he’s not saying, as he points out in the book, that ‘each morning you should get up, tell yourself you’re the most perfect creature in the world and can ignore any advice to the contrary’.

But what he is concerned about is how, by bending over backwards trying to mould ourselves into perfect creatures, we constantly set ourselves up for failure.

‘You know what it’s like. You lose one-and-half stone because society, or your friends, tell you that you should, but then because of the way your brain works, you’ll gain two stone, lose a stone, gain a stone-and-a quarter, and after ten years you’ll be fatter than before. And this does huge damage to your self-esteem. You end up thinking you’re not worthy of being loved, not worthy of living, and this in itself can create problems.’

He firmly believes stress has a contributory role in physical diseases. ‘Stress increases your risk of depression, but also of various forms of cancer and cardiovascular diseases,’ he says. That’s not to say that you shouldn’t worry about being obese, but rather that ‘women who are seven or eight pounds overweight, who aren’t ill, shouldn’t feel guilty for ordering a portion of chips.

‘It’s about balance — but within a life, not within a day. It’s about how you balance things over a week, over a month.

‘In France I’m seen as an Epicurean,’ he says. And it’s true; he’s famous for being friends with some of the country’s top chefs, admits he loves cooking for friends and says that, if he hadn’t been an oncologist, he’d have loved to own a restaurant. ‘But,’ he points out, ‘if you look at what the Greek philosopher Epicurus actually said, it wasn’t that you should have a life of debauchery and be always drunk. He said if you want to have a point of excess, you should balance it.

‘So, when I have a 2,000-calorie lunch with friends, with several glasses of wine, I enjoy it. But for the next 16 hours, I won’t have anything apart from broth, water and tea. And I won’t drink for the next two or three days, so I’m not drinking more than around ten glasses a week. It’s about balance, not about controlling every single minute.’

I don’t point out that ten glasses of wine a week is three more than the seven recommended in the UK; perhaps those Parisian wine glasses are smaller.

Life is a gift. You have to honour it by finding joy and happiness 

Frankly, what would I know? This bespectacled bear of a man, who, despite his huge intellect and accolades, comes across in person as smiling and friendly, has been working in medicine for more than 40 of his 64 years.

He’s clearly a bon viveur, but one who knows how to get the most bang for buck from life. His conversation is sprinkled with fascinating titbits of knowledge. ‘Did you know that the reason Italians can eat so much pasta and not get fat is because, unlike the French and the Brits, they don’t overcook their spaghetti? Al dente pasta doesn’t provoke nearly as much of an insulin response (which tells your body to store fat) as well-cooked pasta.’

Love your life at every age 

According to the professor, your health is grounded in your happiness. Enjoying life is the key to vitality and that means embracing your favourite vices — but not to excess — and releasing yourself from the toxic guilt of feeling you’re not conforming to the latest medical diktats.

He’s reluctant to be prescriptive about anything because so much of the health advice we receive is one-size-fits-all, when actually, as he says, we are individuals and our individual risk factors are a function of our lifestyle, our genetics, and our age.

In an ideal world, he says, we’d work out which bits of health and medical advice were most relevant to us and ignore the rest. But he does offer ‘roadmaps’ that indicate the aspects of health we should aim to prioritise at each stage of life . . .


  • Focus on ensuring your plate is packed with a rainbow of fruit and veg that, ideally, is organic and locally grown.
  • Smoking for 20 to 30 years takes ten years off life expectancy, so think about switching to a vape or e-cigarette.
  • After every alcoholic drink have two glasses of water.
  • Try team sports to boost your mental, as well as physical, health and make time for a club with activities that feed your soul too — whether it’s singing, dancing, reading or art.
  • Start meditating, as 15 minutes here and there will have a real impact on your breathing and stress levels.
  • Shifting weight after the menopause is harder so weighing yourself weekly (in conjunction with physical activity and a good diet) can help keep things in check.


  • You don’t have to go vegetarian, but increase the amount of vegetables in your diet to boost fibre levels and keep you regular.
  • Take a ten-day course of 1g vitamin C daily every two or three months (more than that can put you at a higher risk of kidney stones) to help combat oxidative stress, a contributing factor to cancer.
  • Take 4,000IU of vitamin D daily to help maintain strong bones and protect against cancers and auto-immune diseases.
  • Stay hydrated — 1.5 litres of water a day will keep your organs healthy and help you feel good.
  • Beware of self-medicating with supplements that promise to help cure the menopause. Don’t take anything without consulting a doctor first.
  • Try swimming — it’s a good exercise that won’t put pressure on your joints — walk a lot, and if you cycle, be sure to wear a helmet.
  • If you want to stay youthful, you have to think youthful. That means being positive and amiable, going out and spending time with people who are younger than you.
  • Look after your teeth and see your dentist at least once a year. After the age of 50 plaque has a tendency to attack the gums so you risk losing teeth.
  • Pay attention to your posture, standing up straight can take ten years off you.
  • Have regular check-ups. Don’t miss appointments for mammograms, blood tests for colon cancer, bone density scans and mole examinations, too.


  • As you get older, your appetite might be smaller, but try to keep your diet balanced. Focus on quality proteins and calcium-rich foods, such as dairy products.
  • Think about taking a B vitamin complex to boost skin and hair regeneration. It also has benefits associated with preventing Alzheimer’s.
  • Keep your brain stimulated with intellectual activities that pique your curiosity and mental activity, such as Bridge or Sudoku.
  • Swimming, Nordic walking, which involves walking with poles, and golf keep you fit as well as mobile.
  • Cultivate your social life and seek out laughter, which helps dispel stress and relaxes you. Film clubs, reading groups, anything that stops you being isolated.
  • Don’t let yourself go. As time passes, it’s easy to think the way we look doesn’t matter. It does, because if we look better, we feel better, so keep up the hair appointments and choose clothing with care.

We are so used to being lectured and harangued about everything we’re doing wrong, and so his book — and his attitude — is a breath of fresh air to a world that seems to have become obsessed with fasting, dieting and trying to force ourselves to be something we’re not. And nowhere is that more true than when he’s talking about ageing.

‘The combination of Botox and plastic surgery have helped to create this fantasy that we can stay young for ever, that we can control things so we never get ill,’ he says. ‘But I see people with cancer who have never drunk alcohol and have had sugar-free vegan diets for decades and have still ended up with it.

‘We probably will get ill, and we’re definitely going to die, so why deprive yourself of all the things that give you joy and happiness?’

Another valuable message in his book is that it’s not your fault if you feel under a lot of pressure to be perfect.

He believes we are bombarded with information and very often lack the ability to put it into context; ‘plus there’s no filter as it all goes through social media networks where anyone can say anything they want’. And that while ‘all these messages come from multiple different places, you’re just one person trying to receive them, understand them and put them into perspective. It’s just too much’.

Nobody, he says, explains the difference between risk and danger. ‘Let me give you a metaphor. Sharks are dangerous. Where are sharks? They are in the sea, so it stands to reason that going in the sea is dangerous. But is it risky?

‘The chances that you’re going to meet a shark if you’re swimming off the coast in Nice are negligible. In the same way, a report by the World Health Organisation said that if you eat processed meat — the equivalent of a single ham sandwich every day — you increase your risk of colon cancer by 18 per cent.

‘But your risk of colon cancer if you don’t eat processed meat is 2 per cent. So eating a ham sandwich every day only increases your risk by 18 per cent of that 2 per cent, which is 0.36 per cent. [That means your risk of colon cancer goes from 2 per cent with no sandwich, to 2.36 per cent with a sandwich.] However, most people don’t know that.’

He also believes many of the things we’re told we shouldn’t do are actually addictions. ‘It’s not easy to diet or to quit smoking, but you’re made to feel that if you don’t, and you subsequently have a heart attack, or get cancer, then it’s your fault because you were told that it was bad for you.

‘But when you depend on something, and you can’t get rid of it, that’s a disease. You should be treated empathetically, not made to feel guilty.

‘Twenty years ago, when someone was depressed, people would say, “You just need to get on with it,” but now we understand depression is a disease and treat it. I think the same is true of being overweight or a smoker. You’re caught in a cycle of addiction and you need help to escape.’

He believes in empathy, rather than lectures, and in little things making a difference. ‘You don’t have to go for a run every day, or feel guilty that you’re not a member of a gym, but you could get off the bus one stop early and walk half a mile, or stand up when you make a phone call.’

For the professor, it’s not about the sort of grand gestures you see at New Year or at Lent, when we give things up or make huge resolutions to become paragons of healthy living.

‘The idea that the only way to improve your physical condition is to say that you’re going to turn your life 180 degrees and never do something again is ridiculous.’

Instead, it’s about what he calls ‘baby steps’, compassion and not beating yourself up for succumbing to that glass of wine, that bowl of ice cream, or even that sneaky cigarette. Here’s how …


In his book, Professor Khayat talks about what he calls our seven little weaknesses, or favourite vices, that can easily go from being occasional pleasures to dangerous addictions.

The weaknesses he thinks we should monitor are sun exposure, alcohol, smoking, gluttony, screen time, salt and being sedentary. He says that in themselves these things aren’t the enemy, but overdoing them is the problem. The key to a happy life is to understand the risks and manage them.

‘Let’s not lie to ourselves,’ he says. ‘Going down the road of baby steps, especially at the beginning, is always going to be less easy, less comfortable than allowing yourself to continue to slide unchecked.

‘But remember, only the initial steps are hard, because soon you’ll have the pleasure of having found your personal balance point that will stop you feeling guilty about things you enjoy.’


On the flipside, he talks about the five guardian angels that we don’t always pay attention to but can be counted on to improve our health and wellbeing.

Those five are laughter, sleep, sex, positive emotions, and our gut microbiome — your body’s colony of good bacteria. And, says the professor, we should indulge in them regularly.

Arretez De Vous Priver! by Professor David Khayat is published by Albin Michel and available on Amazon in paperback (£23.03) and on Kindle (£9.99).
