Thanks to modern-day technological advancements, the average American lifespan has actually reached 79—41% higher than it was 100 years ago. But contemporary life has likewise resulted in boost of chronic diseases, which now influence nearly half of every Americans. In various other words, a long life doesn"t always translate to a greater quality the life. <1-2> In fact, your chronological (AKA calendar) age can not accurately stand for your body"s internal or biological age at all.

You are watching: Which kind of aging is most strongly influenced by diet and exercise?

What is organic age? biological age is her body’s interior age. The reveals the efficiency at which her body is working and how well it should it is in working provided your chronological age.

As lifespan continues to increase, our healthspan becomes increasingly important. Unequal lifespan, i beg your pardon is simply concerned with chronological age, healthspan encompasses biological, physical, and mental wellness throughout the aging process. Read about the factors that affect our organic age and the finest ways to measure up it.

Chronological period vs. Biological age
Your chronological age measures your age in calendar years or the variety of birthdays you"ve had. Yet chronological age isn"t necessarily the ideal metric that aging, as our bodies age at various rates—an period of 70, for example, have the right to look incredibly different from one human being to the next. A mix of genetics and lifestyle factors, such as diet, exercise, stress, and also sleep, all play a role in determining how rapid or slow-moving someone ages.

Biological age, top top the various other hand, can offer a more complete understanding of a person"s aging process. Because that example, some individuals may appear fit and also independent in their 70s, while others might look frail and also need assistance. Your biological age reveals just how well your body is working and how fine it should it is in working provided your chronological age.

Factors the influence biological ageScientists continue to do headway in pinpointing the factors and also biomarkers most very closely linked to biological age and healthspan. Here"s what we understand so far.


Genetics influence our organic age and healthspan to a degree, yet perhaps not as considerably as we"ve been led to believe. In fact, follow to longevity scientist David Sinclar, Ph.D., genes just control approximately 20% of our healthspan, and the rest depends on the individual"s way of life or environment. However, over there are specific variations in genes that have the right to influence age-related traits. And also though we can"t change our DNA, expertise these hereditary predispositions can aid influence just how we select to encourage longevity in our own lives.


Leading longevity scientists agree the diet plays an integral function in the price of aging—our diets can either promote inflammation or store it at bay. And also this is critical, together chronic inflammation is the main point of the advance of many age-related diseases, miscellaneous scientists regularly refer to this as “inflammaging.” because that example, the traditional American is high in sugars, fats, and also processed ingredients (pro-inflammatory) and also low in fruits, vegetables, and also fiber (anti-inflammatory). This imbalance leads to an buildup of reactive oxygen types (ROS)—sometimes called "free radicals." A buildup of ROS can reason damage come cells, proteins, and also DNA in the body. Over time, this deserve to lead to increased aging and also the development of countless chronic illnesses.

Furthermore, a plethora the research mirrors a solid relationship between the type of protein we consume and healthspan. One study examined the relationship between dietary protein, its sources (animal vs. Plant-based), and also the risk of mortality. After investigate the diets and also death rates of end 2,000 participants, the researchers concluded the (1) a greater ratio of pet to tree protein and also (2) an overall higher meat intake were both linked with an enhanced risk of mortality.

Another 2019 study analyzed mortality prices in Seventh-Day Adventists, a populace that eats short to moderate quantities of meat. The results shown that Adventists with the greatest intakes the red and also processed meat had a higher risk of all-cause mortality andcardiovascular condition (CVD)mortality compared to participants that ate no meat in ~ all.<3> reducing meat intake and replacing that with much more plant-based proteins has actually been presented to minimize CVD risk (the number one cause of fatality in the U.S.) and also many biomarkers related to it, consisting of cholesterol, triglycerides, and also glucose.<4-5>


Staying physically active also helps to keep a durable immune system, a healthy body weight, and a reduced risk the inflammation. Engaging in constant exercise can, therefore, substantially influence our organic age and increase our healthspan. This study proved that running four to 5 miles every week have the right to lower the hazard of fatality from a heart attack by 40% and all-cause mortality by 45%.

Exercise also works to improve our organic age on a moving level. A study published in the Journal the Preventive medicine showed that people who exercise 150 minutes every week (the encourage guidelines in the U.S.) have actually aging markers nine years younger contrasted to those that led a sedentary lifestyle. Various forms of practice can additionally activate longevity genes, thereby improving our healthspan. High-intensity interval training (HIIT) workouts have actually been shown to stimulate genes linked to longevity.<6>


Biomarkers can indicate the speed at which us age. Research shows that part biomarkers are an ext strongly associated with healthspan than others. Because that example, blood glucose, or blood sugar, is the body"s primary source of fuel, and maintaining optimal levels contributes to all at once health and also longevity. A riches of peer-reviewed clinical literature argues that longevity can be suspect by an individual"s fasting glucose levels—in fact, one examine of much more than 5,000 human being found that lower glucose levels were associated with a much longer lifespan. Furthermore, the well-established that lower cholesterol levels, an especially LDL (“bad”) cholesterol, can be predictive of healthy and balanced aging. Other markers such as vitamin D, cortisol, hsCRP (an inflammation marker) all connect to optimal healthspan together well. Blood biomarkers constantly transition in solution to ours nutrition, fitness, and lifestyle choices and also can be improved over time by following personalized recommendations.


Sleep is extremely necessary for our in its entirety health, and this consists of our healthspan—consistent sleep deprivation may potentially increase the production of pro-inflammatory cytokines (markers the inflammation). Those more, this systematic review uncovered that sleeping for much less than six hours a night is linked with a 12% increased risk of mortality.

Ways to measure organic ageThere are numerous proposed means of measuring biological age, three of which us will talk about here. Telomere length, epigenetic clocks, and biomarker predictors uniquely measure our internal age yet are alike in their ability to be influenced by lifestyle factors.


Telomere length

Research demonstrates a strong relationship between telomere length and also aging. Telomeres, the structures at the finish of chromosomes, tend to decrease v age—shorter telomeres are associated with reduced survival and higher incidence the disease, and also vice versa. However, dietary and lifestyle components can affect their price of attrition. Individuals through healthier diets and also who exercise much more tend to have actually longer telomeres compared to those v chronic diseases and also who lead much more sedentary lifestyles.<7-8>

There are several means to measure up telomere size (and, therefore, biological age) however all differ in your accuracy. The terminal border fragment (TRF) is the oldest method to measure telomeres and remains the “gold standard” in research study settings, yet it is not commercially available. The “flow-FISH”(flow cytometry and also fluorescence in situ hybridization)analysis has been supplied in clinical setups to measure up telomere length yet only in particular patients. Some companies now offer ways to measure up telomeres through a method called quantitative polymerase chain reaction (qPCR), despite variability in that is accuracy and also the lack of actionable info it gives has triggered some criticism.<9>

Epigenetic clocks

The ar of epigenetics examines the methods that ours behaviors and also environment influence how our gene work. One type of epigenetics dubbed DNA methylation can reason genes come "turn off" by adding particular chemical groups to DNA, in order to blocking proteins responsible for reading a gene. Our environment, lifestyle, diet, and the general aging procedure can all influence DNA methylation, and also epigenetic clocks space tools to measure up this (thereby measuring biological age).<10> one of the most renowned and an ext accurate clocks is based on the Horvath calculator—an algorithm emerged by Dr. Steve Horvath that predicts organic age based on DNA methylation. Longevity concentrated companies have now started to commercialize the Horvath’s Clock to offer epigenetic period prediction tests come consumers.

Biomarker predictors’s InnerAge model relies on biomarkers and personalized data to calculation a biological age.’s team of data scientists determined biomarkers many strongly regarded aging and an unified these insights with machine learning to design a design that calculates InnerAge and the measures needed to lower it. The list of biomarkers arrays from those regarded cardiovascular health like glucose and LDL (‘bad’) cholesterol to those concentrated on liver duty like GGT. The list also includes biomarkers pertained to inflammation, immunity, blood oxygen saturation, and BMI, to name a few.
