Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Metabolic syndrome is associated with a 56% increase in age-adjusted risk of cancer mortality.

◐Partially SupportedDEXA scans are valuable for measuring visceral adipose tissue and muscle mass, providing a more relevant assessment than body weight or BMI.

◐Partially SupportedHaving three risk factors for metabolic syndrome increases Parkinson's disease risk by 31%, while having all five increases it by 66%.

✕Not SupportedWeight and BMI are crude indicators of body composition.

◐Partially SupportedA typical blood draw to track metabolic health should include fasting insulin, fasting glucose, and hemoglobin A1C.

◐Partially SupportedMetabolic syndrome is associated with a 37% increased risk of all forms of dementia.

◐Partially SupportedHaving one or two metabolic syndrome criteria is worse for health than having none.

◐Partially SupportedAbdominal obesity may be a consequence of Alzheimer's disease rather than a cause.

◐Partially SupportedC16 saturated fatty acids and intramuscular biopsies are used in research to assess fat metabolism and storage relevant to insulin resistance.

✕Not SupportedBody Mass Index (BMI) is not a helpful metric for assessing metabolic health because it does not account for body composition or insulin sensitivity.

✕Not SupportedCT scans and MRI with appropriate software can provide visceral fat measurements.

◐Partially SupportedIn the US, as of 2021, there were 108 million obese adults (BMI > 30) and 150 million non-obese adults.

◐Partially SupportedMetabolic disease is considered one of the four major diseases of aging.

◐Partially SupportedPeter Attia does not use BMI to manage patients and focuses on individual metabolic health rather than population-level metrics.

◐Partially SupportedLiver ultrasound, combined with algorithms that integrate ultrasound data and blood tests, is important for assessing fatty liver disease and fibrosis scores.

◐Partially SupportedFunctional tests for metabolic health include Zone 2 output, CPET testing, oral glucose tolerance tests, continuous glucose monitoring (CGM), and whole-body respiratory suites.
