Today I want to write about something I wrote on nearly a year ago. It concerns getting our bodies in the shape and condition that we would be happy with.

A lot of people – probably the majority – have got it into their heads that there is nothing they can do about middle age spread – that it is an inevitable consequence of getting older.

This is not so. It is totally within our gift as to what weight and shape we are.

My method – and it has worked for me – is to fast one day and eat the next, with two days eating at the weekend. In just four weeks I got my weight down from 14st 1lb to 12 stone 7lbs (21lbs). There are many incredibly good aspects to this method… if only I had thought about it during my twenty five years of running health clubs!

The first is the breathtaking speed at which the weight fell away; there was no agonising for months and months as you nibble away at the pounds. The second is that you can carry on eating the things you like and in the same quantities you are used to. There is no having to fork out for expensive dietary lines, many of which I don’t like and forsaking the wonderful things that you do. Third, you’re getting a regular detox. Normally our digestive and bowel systems are working 24/7, with never a let-up. Now they have a rest and a thorough flush out. Fourth, while you’re pursuing your goal, you’re massively reducing your supermarket bill as a result of the 40 per cent calories you are no longer consuming.

This inspirational thought which came to me out of the blue allowed me to go into this summer and the last unencumbered with all that useless and damaging baggage. To ensure that it never came back after I reached my goal I could have cut my calorific intake for the future, but I prefer to eat what I want to in the quantities I want.

Every so often – usually every week or ten days – I nuke it with a day of fasting in which I can easily knock off two whole pounds or more. Wonderful, I think to myself. I’m back to ground zero!

Now, I know your reaction to all this is: ‘Great! But those days of fasting must be sheer purgatory.’ This is not so. Like you, I thought they would be, but they were amazingly easy to get through. Yes, I had odd moments when I could have stuffed myself, but they soon passed. I thought of the joy I would feel the following morning when I got on the scales.

Amazingly, I felt so alive and focused on those days of fasting. Why was that? I believe it goes back to our hunter gatherer days, which after all is only ten thousand years ago. Then it was a life of feast and famine. When you and your family had gorged itself on your latest kill you had to think about the next meal. Days might pass before you could bag that fleet of foot antelope for your next feast.

Nature equipped you to get through those days of hunger without feeling below par. You had, if anything, to be even sharper and more focused than normal to run your next kill to ground, certainly not lethargic and off key.

Evolution does not fundamentally change our digestive or any other system in a short time span like 10,000 years. To evolution, it is a mere blink of the eye.

My plan, I will freely admit, is not rocket science, but it is radical and it does work. And the speed at which it works is phenomenal and that is what makes it so exciting.

So why haven’t we heard of this in all the years we’ve been regaled about dieting? There is so much ballyhoo about losing weight one could be forgiven for thinking that it is complicated when it isn’t. I believe it’s all down to calories; the number going in versus the number going out.

But could it be that money is the reason we haven’t heard of it?

The dietary industry is worth billions and the supermarkets even more. Imagine if millions of people start consuming 40 per cent less food each week and abandon dietary products altogether. I’m not, by nature, a conspiracy theorist, but I do believe it would tantamount to suicide for those two mammoth industries ever to allow such thinking to take hold.

Of course, exercise can and should play its part, though its greatest contribution is its benefit to the cardio vascular system and general all round health. It also aids your immune levels to stay high and so ward of attacks of this or that. But to burn up the excess number of calories that Western man is piling on each day by exercise alone would take an effort beyond anything that all but the most heroic could endure.

As in so many things, we tend to follow in Uncle Sam’s footsteps and are usually the first in Europe to do so. Most of them are beneficial, but over indulgence is certainly not one of them. We are now officially the fattest nation in Europe. No single thing could aid our aging and increasingly overweight population than to take obesity seriously – and it should start with our children. As the best form of preventative medicine, it would massively reduce the spiralling burden and costs of our health service.

Friends that we holiday with from Sweden from time to time were telling my wife last week, via Skype, that a new craze is sweeping the country… fasting your weight off, one day on and one day off, with two days of eating at the weekend. Ausra, my wife’s friend, said that the word is that the scheme came from England.

I wonder if Yours Truly began it all with that article nearly a year ago in this paper? The blog version of it went out on the World Wide Web. Something of a thought isn’t it? I’d love to think that is what happened.

All power, I say, to Sir Tim Berners-Lee’s invention of the web. Now, there’s a man who really does merit the Turing Award, the Nobel prize of computing. Think just of one benefit alone: the alleviation – through Skype and other instant messaging services – of the loneliness of people whose loved ones have gone abroad. The call, no matter what its duration, is cost free and the whole thing is totally brilliant.
