This Harvard longevity researcher, 53, says he de-aged himself by a DECADE thanks to these four daily hacks

A biohacking Harvard researcher claims he has de-aged himself by a decade after taking up four simple daily habits in middle age.

David Sinclair, a molecular biologist, has now had 53 birthdays — but claims DNA testing suggests his body is still 43.

Biological age looks at the health of cells rather than how long someone has actually been alive.

He was prompted to start the healthy routine in his 30s after becoming overweight and drinking too much.

So what's his secret?

These are his four tips for reversing aging: (Do aerobic exercise such as running to live longer, researchers say)

Run three times a week

A cornerstone of almost all anti-aging plans is exercise.

It helps to maintain muscles, boost heart health, avoid obesity and reduce inflammation in the body — which can all drive age-related changes to cells.

This can include swimming, cycling, rowing a brisk walk — or running.

Previous research has suggested that running for just 30 minutes a day could reverse cellular aging by nine years.

Eat just a few hours a day

(Intermittent fasting may help extend lifespan)

People should try intermittent fasting to slow aging, according to Dr Sinclair.

Limiting calorie intake to just a few hours a day can boost insulin sensitivity, protecting against diabetes, and allow time for cells to flush waste substances out of the body that could cause harmful changes — both helping someone live longer.

Drink matcha green tea twice a day

(Drink matcha green tea for longevity, studies suggest)

Dr Sinclair drinks two matcha green teas every day without fail.

The teas — made from powdered tea leaves — are known to contain anti-oxidants, which can help limit damage to cells.

But whether or not they can slow aging in humans is yet to be backed up by rigorous scientific studies.

Reduce stress and avoid 'jerks'

(Reducing stress can help with longevity, an expert says)

Stress and being irritated by 'jerks' can all decrease someone's life expectancy, the expert suggested.

This is because they can lead to chronic levels of stress, raising inflammation levels that put the body at risk of a whole host of diseases including heart problems, sleep issues and obesity.

They can also prompt stress-related changes to the DNA in cells, speeding up aging.
