Harvard professor says: We can now reverse aging!

What does it take to grow old but never age? Can you imagine being 120-years-old?

This Harvard professor may have the key to stop aging.

David Sinclair is a professor in the Department of Genetics at Harvard Medical School and co-director of the Paul Glenn Centre for the Biological Mechanisms of Ageing. He has been working for years on the idea of how to slow down the aging process.

He declares that with the technology we have today we can even pause it for a while. His team is aiming high, wanting to completely stop the course of aging.

The question Sinclair often asks is “Today the oldest living people reach 115-120 years of age, but why should life stop there?”  He recently published a book called “Lifespan: Why We Age – and Why We Don’t Have To”  where he explains the process of aging and how can we overcome degeneration. The main thing he highlights is that according to him there is no biological limit to human lifespan. The book is said to be covering those scientific subjects in a fundamentally new way.

The Theory

According to Sinclair aging should be classified as a disease. His argument on this is that we normally accept this process only because it happens to everybody.

“When it comes down to it, aging is just another disease, 100 years ago, people accepted the fact that once you had cancer, you were a goner. Today, we’ve dramatically improved the chances of survival.”

David Sinclair considers that if our bodies continue to produce NAD – nicotinamide adenine dinucleotide, the same level as they do when we are 20, we could potentially prolong our lives. His best advice on this subject is “Eat less!”  He notes that the quality of food we eat is as important as the quantity.

The Study

In 2013 Sinclair published a study showing that aging mice became more youthful when they were given NAD producing supplementation. In fact, the metabolism and muscle tone of the examined mice improved rapidly. To raise NAD levels in mice he was using NMN – nicotinamide mononucleotide. This led to mice having a 60-80% boost in athletic output on a treadmill. The mice that were given NMN also improved blood vessel plasticity and resilience.

Another precursor of NAD is NR – nicotinamide riboside, which is naturally present in milk. They gave this additive to worms and yeast. The result was that those organisms that were given NR lived longer than the other ones.

The Advice

The Harvard professor believes that our greatest enemies in the battle against aging are obesity, smoking and the lack of exercising. What he practices is intermittent fasting – he skips breakfast, has a late lunch and an early dinner. Sinclair says that by fasting, we can boost our NAD levels which activates our repair genes. He also adds that exercising is the other thing that makes us younger. This happens because when we eat less and work out intensively, our bodies are trying harder to keep on working as usual. The result is stimulating the NAD producing cells.

In addition to keeping up with a specific diet and regular exercise schedule, David Sinclair recommends taking a group of supplements that help to decrease the aging process. He particularly suggest NMN – the supplement that the body transforms into NAD by stressing the body with exercising or fasting.

The Routine

The Harvard professor follows a specific daily routine. When he has breakfast, he usually eats a yogurt with an NMN supplement. Sinclair often skips meals and when he doesn’t, he tries not to overeat. He exercises on the weekends mixing weight training with high-intensity running. Moreover, he is strict with his sleeping schedule as well. He claims that undersleeping has negative effects on NAD levels. What he does to improve his sleeping cycles is wearing glasses with a blue light filter. To add up to his healthy lifestyle, David also practices meditation.

The Future

David Sinclair strongly believes that the question is not if we can reverse aging, but when. He says that the aging clock starts ticking even before we are born so the earlier we start fighting aging, the better. He hopes that not only the technologies we have now but the ones that are going to be created in the future will benefit cellular reprogramming. In other words, we would be able to tell the cells to look for the information that existed when they were young and ignore all the other information that piled up over time. It’s basically like sending an old cell back in time.

“There are technologies that are just around the corner that could really change the world.”

Sinclair believes that everybody should have a purpose in life in order to be healthy and contribute to the society. His purpose is leaving a mark on the planet and he’s doing it by dedicating his life to finding a cure for aging.
