Restricting the amount you eat is said to fight disease, extend lifespan and improve wellbeing. As well as dieters, people with diabetes and MS could benefit
THERE’S a fuzz in my brain and an ache in my gut. My legs are leaden and my eyesight is blurry. But I have only myself to blame. Besides, I have been assured that these symptoms will pass. Between 10 days and three weeks from now, my body will adjust to the new regime, which entails fasting for two days each week. In the meantime, I just need to keep my eyes on the prize. Forget breakfast and second breakfast, ignore the call of multiple afternoon snacks, because the pay offs of doing without could be enormous.
Fasting is most commonly associated with religious observation. It is the fourth of the Five Pillars of Islam. Buddhists consider it a means to practise self-control and advocate abstaining from food after the noon meal. For some Christians, temporary fasts are seen as a way of getting closer to God. But the benefits I am hoping for are more corporeal.
A new surge of interest in fasting suggests that it might indeed help people with cancer. It could also reduce the risk of developing cancer, guard against diabetes and heart disease, help control asthma and even stave off Parkinson’s disease and dementia. Many of the scientists who study fasting practise what they research, and they tell me that at my age (39) it could be vital that I start now. “We know from animal models,” says Mark Mattson at the US National Institute on Aging, “that if we start an intermittent fasting diet at what would be the equivalent of middle age in people, we can delay the onset of Alzheimer’s and Parkinson’s.” Surely it’s worth a try?

Scientists are uncovering evidence that short periods of fasting, if properly controlled, could achieve a number of health benefits, as well as potentially helping the overweight, as Michael Mosley discovered.
I’d always thought of fasting as something unpleasant, with no obvious long term benefits. So when I was asked to make a documentary that would involve me going without food, I was not keen as I was sure I would not enjoy it.
But the Horizon editor assured me there was great new science and that I might see some dramatic improvements to my body. So, of course, I said, “yes”.
I am not strong-willed enough to diet over the long term, but I am extremely interested in the reasons why eating less might lead to increased life span, particularly as scientists think it may be possible to get the benefits without the pain.
How you age is powerfully shaped by your genes. But there’s not much you can do about that.
Calorie restriction, eating well but not much, is one of the few things that has been shown to extend life expectancy, at least in animals. We’ve known since the 1930s that mice put on a low-calorie, nutrient-rich diet live far longer. There is mounting evidence that the same is true in monkeys.
