7 Day Plan: This week you are going to measure, estimate, or order every longevity biomarker discussed this week. By day 7, you will have a complete baseline — the starting point for every optimization that follows.
Day 1 — Order your blood panel: Contact your physician to order: fasting insulin, CRP, ApoB, homocysteine, vitamin D, omega 3 index, and HbA1C. Schedule the draw for a fasted morning this week.
Day 2 — Test your grip strength. Use a handheld dynamometer or squeeze a bathroom scale with both hands. Men: target above 40kg. Women: target above 26kg. Below these thresholds predicts meaningfully elevated mortality risk.
Day 3 — Estimate your VO2 max. Calculate: 15 x (max HR / resting HR). Measure resting HR first thing in the morning before getting out of bed. Max HR estimate: 220 minus your age. Find where you fall on normative tables.
Day 4 — Assess your muscle mass proxy. Record your waist circumference and waist-to-height ratio (waist / height in the same units). Under 0.5 is optimal. This is a validated proxy for visceral fat burden and relative muscle mass.
Day 5 — Log your diet for 24 hours. Track everything you eat today using a tracking program or notebook. Note: total protein (target 0.7-1.0g per lb bodyweight), omega-6:omega-3 ratio (target below 4:1), and fiber intake (target 30+g). High omega-6 sources include soybean oil, corn oil, sunflower seeds, and mayonnaise. High omega-3 sources include oily fish (salmon, mackerel, sardines), flaxseed, chia seeds, and walknuts.
Day 6 — Time your gait speed. Mark out 10 meters and time how long it takes to walk at your normal pace. Under 10 seconds is normal for adults under 65. Gait speed is a validated mortality predictor that takes 30 seconds.
Day 7 — Compile Your Longevity Dashboard. Collect all measurements from this week into one document. Note which are in optimal range, which are borderline, and which need immediate attention. This is your biological baseline — reassess in 6 months.
From the Neurologist:
This week is measurement, not intervention. The value is in establishing a baseline you can track over time. Expect some numbers to be worse than you hoped — that is precisely the point. What gets measured gets managed. Most people who complete this week describe it as the most clarifying health audit they have ever done.
Call to Action:
Share your VO2 max on social media this week. It is the number that most consistently surprises people - in both directions. And keep us updated on your progress.
