Bone Density and Healthy Aging
Why skeletal health quietly determines independence in later decades, and what the trials say actually helps — loading and nutrition.
Read →What's a Good VO2 Max? Norms by Age and Sex
What counts as a good VO2 max by age and sex? See normative ranges from Cooper Institute, ACSM, and FRIEND data, and where your own number lands.
Read →Blood PhenoAge vs Epigenetic Clock Tests
Blood PhenoAge and epigenetic clocks both estimate biological age. Here's how the two test types differ on cost, evidence, and what each actually measures.
Read →Low Albumin and Longevity: What It Signals
Low albumin is tied to higher mortality in older adults. What albumin signals about inflammation and aging, and why it's a biological age marker.
Read →RDW Blood Test: What a High RDW Means
RDW measures how much your red blood cells vary in size. What a high result means, RDW-CV versus RDW-SD, and why it predicts mortality even without anemia.
Read →How to Lower Your Biological Age: What Works
How to lower your biological age, according to the trials: what caloric restriction, exercise, and diet moved on aging clocks, and what didn't.
Read →The 9 Blood Markers Behind Your Biological Age
The nine PhenoAge blood markers behind your biological age, what each one signals, typical ranges, and why albumin and lymphocytes push the score down.
Read →What Your PhenoAge Score Actually Means
Your PhenoAge score turns nine blood markers into a phenotypic age. What the number means, how age acceleration works, and what it can't tell you.
Read →Waist Circumference vs Weight: The Better GLP-1 Metric
Waist measurement vs weight loss on a GLP-1: why your waistline can track visceral fat and health risk better than the number on the scale does.
Read →Metabolic Markers to Track on a GLP-1: A1c, BP, Lipids
Beyond the scale: the A1c, blood pressure, and lipid markers worth tracking on a GLP-1, what healthy targets look like, and how the trials moved them.
Read →Am I a GLP-1 Non-Responder? How to Tell
On a GLP-1 but not losing weight? How to tell a true non-responder from a slow start, the under-5% trial benchmark, and what to check before quitting.
Read →Non-Scale Victories: Tracking GLP-1 Progress
Non-scale victories on a GLP-1: quieter food noise, looser clothes, better labs, and steadier energy — how to track progress when the scale stalls.
Read →How Often Should You Weigh Yourself on a GLP-1?
How often to weigh on Ozempic and other GLP-1s: what the self-weighing research shows, why daily weight swings, and how to read the trend not the number.
Read →What to Track on a GLP-1: Beyond the Scale
What to track on a GLP-1 beyond the scale: waist, body composition, protein, side effects, and lab markers, plus why weight alone misleads.
Read →TDEE vs BMR: What's the Difference?
TDEE vs BMR: BMR is the calories you burn at rest, TDEE is your full daily burn. Here's the difference, how each is calculated, and which number to use.
