Your chronological age and your biological age dont necessarily match. Around the ages of 44 and 60 the aging process accelerates in what has been dubbed a biomolecular shift, which dramatically impacts health and internal aging. Researchers discovered these two bursts of aging during the human lifespan, singling out the mid-forties and early sixties as key periods. But the greater shift in biological aging happens during your early sixties.However, out of this seemingly bad news is some hope. Now that science has pinpointed when these changes occur, it could help researchers uncover what is driving chronic disease as we age, potentially leading to earlier diagnosis or even strategies for prevention. So exactly what is going on during these periods of rapid biological aging, how do they impact health, and what can you do to be proactive? Lets break it down.Aging Isnt Primarily GradualYou can no longer assume that aging happens gradually. Ever notice that some people seem to age overnight or are really showing their age? While there is obviously gradual decline, more dramatic changes happen quickly and during certain periods of life. It all comes down to the molecules that make up your physical body. These individual molecules are what age, and studies reveal that they undergo greater change at certain ages, making aging non-linear or not so much gradual over time.How Periods of Rapid Biological Aging Impact HealthIn both your mid-forties and early sixties most people experience molecular level changes related to skin and muscle aging, cardiovascular disease, and the metabolizing of caffeine. This is why people tend to start or increase cholesterol or blood pressure medications during these times of life.Researchers also noted differences between the two periods of biological aging. People in their forties had a greater shift in relation to fat and alcohol metabolism, while those in their sixties underwent shifts related to immune regulation, carbohydrate metabolism, and kidney function.These facts seem to correlate with experience as many people in their sixties are less able to fight off sickness and are even more prone to weight gain and kidney trouble or even kidney failure. Cancer rates tend to spike around this time as the immune system is less able to fend off the invasive cancer cells. Cases of heart disease also rise during this time as people struggle more with their weight and rising cholesterol levels.Less expected, however, was the evidence of rapid aging during the mid-forties. But it becomes more understandable as you consider what characterizes the lives of most people during this life stage. Lifestyle makes a difference and life moves at a rapid pace during your forties. Often this is a time of busy family and work schedules, high work stress, divorce, and weight gain. You often have less time for self-care during these frantic years, and all combined, this shifts your body into a period of rapid molecular aging.Combat Biological Aging with Proactive StepsYou obviously cant stop the aging process but its possible to slow it down. The steps to achieve this arent all new or innovative. In fact, it involves putting common knowledge into practice which many people resist, at least until later life. Here are some unsurprising practical tips for slowing biological aging: Avoid weight gainEat more fruits and vegetablesControl diabetes and high blood pressureStay physically activeDont smoke And the way to prevent or avoid diabetes and high blood pressure is to limit sugar, processed carbohydrates, and saturated fats. If youre in your 40s, in addition to the above, its also beneficial to monitor and minimize your cholesterol levels, exercise to build muscle mass, and limit or avoid alcohol.

Adjust your lifestyle while youre still healthy, and you will see the biggest payoff. However, its never too late to start living with your health in mind, because changes at any stage will make a positive difference.Key Takeaways About Biological Aging in Your 40s and 60sScience previously thought that the human body aged gradually in linear fashion, but recent studies show that aging on a molecular level occurs rapidly during the mid-forties and early sixties. During your forties, this change is often due to lifestyle changes that can be altered for better outcomes. You can slow the aging process during midlife with regular exercise and a diet rich in produce and low in saturated fat and processed carbohydrates.
