Continuous Glucose Monitor (CGM) Lifestyle

What is Continuous Glucose Monitor (CGM) Lifestyle?

A CGM is a small sensor worn on the arm or abdomen measuring interstitial glucose every few minutes, transmitting real-time data to your phone. Higher glucose variability and more frequent spikes are independently associated with accelerated aging, cardiovascular disease, and mortality — even in non-diabetics. CGMs provide personalized, actionable data about your metabolic responses. Most healthy people need only 1-2 months of data before they internalize their patterns and can make informed choices without the sensor.

How do you do Continuous Glucose Monitor (CGM) Lifestyle?

  1. 1.Get a CGM: Dexcom G7 or Abbott Libre 3 (prescription), Stelo by Dexcom or Libre 2 (OTC in the US); Levels Health and Veri provide CGM + app + coaching bundles
  2. 2.Wear for a minimum 28-day learning period: eat normally for week 1 to establish baseline, then systematically test different meals, exercise timing, sleep, and stress to map personal metabolic responses
  3. 3.Target metabolic benchmarks: average glucose 85-100 mg/dL, standard deviation <15 mg/dL, time in range (70-120 mg/dL) >90%, post-meal spike <30 mg/dL above baseline, fasting glucose 72-85 mg/dL
  4. 4.Apply the glucose-flattening playbook: eat protein and fiber before carbs (reduces spike 30-40%), walk 10-15 minutes after eating (most effective single intervention), add vinegar or cinnamon to high-carb meals
  5. 5.Graduate to periodic check-ins: after 1-2 months, you know your trigger foods; wear a CGM for 2 weeks every 6-12 months to recalibrate and catch metabolic drift

How long does it take?

5 minutes daily (1-2 month intensive learning phase).

Is it hard to start?

easy.
