In the U.S., we spend almost $5 trillion on healthcare, 17.6% of our GDP — that’s $14,750 per person. And we are not healthy: 40% of Americans are obese, 39% will develop cancer in their lifetime, and 12% are diagnosed with diabetes. This sounds dismal.

What is Health?

The answer might seem obvious, but each of us is unique.

For me, a healthy body means doing activities with my children and not getting left behind. It also means keeping in shape so when my grandchildren are old enough, so I won’t be left behind then, either.  For Hayley, it means cultivating energy, stamina, nutrition, joy, and emotional well-being to care for her family and being a great friend. For Hillary, a mom in her forties, her focus is now on longer-term goals, such as increasing muscle mass and bone density.

And for Garland, health is defined as having the physical stamina and mental energy to continue interacting positively with his wife, family and friends, and with as many of the the people around me as he can; and still being able to give strength, experience and capabilities to make small but meaningful contribution to the well-being of the world.

But at the end of the day, how do we know we are healthy?  Achieving health is a lifestyle.  It is not just taking multiple supplements or running a marathon.  It is not just avoiding red dye and eating only plants.  There are people who eat no processed foods, compete in triathlons, eat all the ‘right’ supplements and still die of heart disease or cancer.

We certainly cannot predict disease, but what we can do understand is that a healthy life is a mindset for living each day to our full potential.

Three Measurements of Health

To simplify things, we began with the most basic ways to find out your current health status. We found just three items you can tick off to help determine whether you are on the right track to achieving longevity.

If you are obese, weak, and not flexible, these measurements will be hard to achieve.  If you eat a balanced healthy diet of fresh vegetables, fruits, healthy fats and protein, exercise regularly, and get enough sleep, you will most likely complete these exercises. From there, you can determine that you can toward reaching your healthy goals for your age.

What is your VO2 Max?

Peter Attia, MD, who wrote Outlive: The Science and Art of Longevity, points to VO2 max as the best predictor of longevity.

It is not just a measurement for athletes, but a cardiovascular indicator for everyone.

VO2 Max is the maximum amount of oxygen your body can absorb and use during exercise. When you breathe, your lungs take in oxygen and deposit it into the bloodstream. Your heart and blood vessels take the oxygen-rich blood and send it to your muscles, which use it to work hard and contract.

Oxygen is also necessary for your cells to create ATP, your cell’s energy engine. This molecule found in our cells provides energy for cellular functions, nerve impulse transmission, and protein synthesis.  Basically, the more efficiently you use oxygen, the more ATP your muscles produce.

In a study of over 100,000 individuals, there was a clear trend between VO2 max levels and mortality risk.

The results showed that higher VO2 max levels were associated with lower all-cause mortality risk, with the most significant difference observed between the lowest fitness group and the other groups.

The most precise way to measure your VO2 max is to go to a lab where you run or bike with a Darth Vader-looking mask.  You can search Fitnescity for a location or ask your doctor. Fitness trackers also measure it, but they are not as accurate.

Improving Your VO2 Max

While VO2 max naturally declines with age, you can improve or maintain it with regular exercise, particularly high intensity interval training, which is also good for your brain.

Can you hang?

Hanging from a bar measures your grip strength, which measures your overall muscle ratio – a good indicator of overall fitness.

We use our hands for virtually everything: weight training, gardening, opening jars, vacuuming, cooking, pulling suitcases through long airports…the list is endless.

If your grip is strong, it means that your arm and shoulders are strong and that you have been exercising. If you are exercising, you probably have an appropriate BMI and body fat percentage.

Interestingly, according to a meta-analysis published in NIH, a decline in grip strength can lead to heart disease, arthritis, osteoporosis, Type 2 diabetes, and certain cancers.

Attia says that a 40-year-old woman should be able to hang for 1 minute 30 seconds and a man for 2 minutes.

Can you stand up and sit down without your hands?

Kelly and Juliet Starrett wrote the book, Built to Move, outlining ten essential habits to help you move freely and live fully.  One of their mobility tests is your ability to get up and down off the floor without assistance.

In a joint study published in a 2014 European Journal of Preventive Cardiology, researchers observed and scored 2,002 men and women ages 51-80 on how well they performed the sit and rise test. The more the subjects had to use their hands, the lower the score. The bottom 8% of performers had a lower survival rate.

What do these tests have to do with food?

A healthy lifestyle can sound complicated but basically it boils down to two things: move a lot and eat well.

We have all heard that ‘sitting is the new smoking’.  If you are sedentary, your body is not strong, flexible, and can efficiently burn calories. Your risk of cardiometabolic disorders just goes up. Many of us who must sit at our desks a lot of the day try to stand up every 45 minutes and move around.

Fat doesn’t make you fat — sugar makes you fat. Eating well really means eating fruits and vegetables, healthy fats, protein, and staying away from sugar. Excess sugar is what gets stored as fat, not necessarily excess healthy fats.

The Lancet documented 5,800 deaths and 4,800 cardiovascular disease events.  They found that higher saturated and unsaturated fat intake was associated with lower risk of stroke and not associated with cardiovascular disease mortality.  Whereas high carbohydrate intake (sugars) was associated with a higher risk of mortality.
