@drgreghealth: Here are the three markers I see most often in the clients who live the longest. I've been a functional medicine doctor for more than 25 years, and these aren't the numbers on your annual physical. Number one: Grip strength. It sounds simple, but it's one of the most predictive numbers in medicine. The same 140,000 person study tied weaker grip strength to higher cardiovascular death, higher all-cause mortality, and a greater risk of cognitive decline and dementia. Most doctors never measure it. Number two: Fasting insulin. Your glucose can look perfectly normal for years while your insulin is quietly climbing behind the scenes. By the time glucose finally rises, the metabolic damage is already underway. This is the earliest warning sign of metabolic disease, and it's almost never ordered on a standard panel. I like that number between two and five. Number three: High-sensitivity CRP, or hs-CRP. It's a marker of chronic inflammation, the common thread running under heart disease, dementia, and most of what shortens a life. It catches these things years before the diagnoses show up. I want that number under 0.3. Your annual physical checks cholesterol and glucose. My longest living clients are the ones who know these three numbers instead. Find the root. Heal the whole.
