Optimizing Longevity

The US Senate Special Committee on Aging recently discussed how to optimize longevity in America. Dr. Rhonda Patrick testified in front of the committee on February 12th, 2025, Dr. Patrick is someone I listen to regularly and receive health study emails from. She goes above an beyond to break down research into easily digestible information. Here is a summary of her testimony from the senate hearing.

The US is overfed but undernourished. The trifecta of ultra-processed foods includes the following.

• No satiety

• Cheaper than whole foods

• Addictive

60% of all calories consumed by Americans come from ultra processed foods. Excess calorie consumption is one part of the problem. As a population, we are nutrient deficient

• Low Omega 3 Levels

  • Affects 80% - 90% of Americans

  • Carries the same mortality risk as smoking

    
    

• Vitamin D Deficiency

  • Easily corrected

  • Compromises immune function, cognitive function & longevity

    
    

• Magnesium Deficiency

  • Impairs DNA repair

  • Increases the risk of cancer

Dr. Patrick went on to state that these health issues are not being solved, they are being medicated. Americans over 65 take 5 or more medications daily (polypharmacy). All these medications add up to increased complexity when it comes to health and longevity.

Strength Training

Physical inactivity carries the same risk as smoking, heart disease and diabetes. Going from a low cardiorespiratory fitness to a low normal adds 2.1 years to your lifespan.

Incorporating strength training is not about looking strong, it's about survival and being able to do more of what you enjoy as you get older.

By age 50, Americans have lost 10% of their peak muscle mass. By 70, most people have lost up to 40% of their peak muscle mass.

Benefits of Strength Training

• Strength training slows aging, increases muscle mass, strength and bone density

• Higher muscle mass leads to improved insulin sensitivity & 3% lower mortality risk

• The strongest middle-aged Americans have a 42% lower risk of dementia

Hip fractures alone kill 20 - 60% of older adults within a year. Strength training lowers your risk of fractures by 30 - 40%.

If we want to prevent muscle loss and frailty we must update current protein recommendations and make strength training a priority. The current recommended daily allowance (RDA) is too low for people in general but especially older adults.

When the RDA was increased by half there was a 32% reduction in frailty. Doubling the RDA and adding consistent strength training lead to a 27% increase in muscle mass and an overall strength increase of 10%. Having more lean muscle mass is one of the biggest indicators of longevity. 70% of Americans are overweight or obese. This is worrying seeing as the US spends 15% of the GDP (more than any other country) on healthcare and yet rank 55th when it comes to life expectancy.

Takeaways

Being consistent with your strength training routine has massive positive health benefits not just now but for future you. Seeing as we also prioritize both strength training and making sure we get enough zone 2 at The Pillars of Health, this means you have a lot of the bases covered in relation to a lot of the topics that Dr. Patrick discussed above. Bottom line, be consistent and reap the benefits.
