Waist-to-Hip vs. Waist-to-Height: Which Ratio Should You Track?
Waist-to-hip ratio and waist-to-height ratio are both quick, powerful health metrics, but they answer different questions. Here's what each captures, the thresholds that matter, and why we lean on waist-to-height for cardiometabolic risk.
Read article →Body Fat Measurement Methods Compared: From Calipers to DEXA
Smart scales, calipers, the Navy tape method, DEXA scans — they all estimate body fat differently, with very different accuracy. Here's how each works, what it costs in precision, and which to trust for tracking change.
Read article →Sleep and Metabolic Health: The Overnight Factor in Weight and Blood Sugar
Sleep is often treated as the optional pillar of health. The metabolic evidence says otherwise: even a few nights of short sleep measurably worsen insulin sensitivity, appetite hormones, and food choices. Here's what happens and how to protect it.
Read article →VO₂ Max and Longevity: Why Fitness Predicts Lifespan
Your VO₂ max — a measure of how well your body uses oxygen — tracks closely with mortality risk. The research suggests improving your fitness may rival or exceed many medical interventions for extending healthy life.
Read article →Strength Training Is Metabolic Medicine, Not Just Aesthetics
Lifting weights is often framed as a way to look better. Its more important payoff is metabolic: better blood sugar control, preserved muscle with age, stronger bones, and a more resilient body. Here's the case for treating strength training as medicine.
Read article →Insulin Resistance and Metabolic Syndrome, Explained
Insulin resistance develops silently for years before it shows up on a standard blood test. Understanding it — and the cluster of signs called metabolic syndrome — is key to catching cardiometabolic risk early.
Read article →Fiber: The Forgotten Nutrient Most People Don't Get Enough Of
Most adults eat barely half the fiber they need. That shortfall affects blood sugar, cholesterol, appetite, and the gut microbiome. Here's how much you actually need, why it matters, and where to get it.
Read article →What Is the IFM Cardiometabolic Framework?
The Institute for Functional Medicine's Cardiometabolic framework goes beyond standard risk screening to identify and address the root causes of metabolic disease. Here's what it is and why it matters.
Read article →How to Measure Your Body Circumference — Methods, Tools, and Exactly Where to Measure
Accurate circumference measurements are the foundation of body fat estimation, waist-to-height ratio, and body composition classification. Here's where to measure, how to measure, and what tools to use.
Read article →How to Interpret Your Waist-to-Height Ratio
Waist-to-height ratio is a better predictor of cardiometabolic risk than BMI — but most people have never heard of it. Here's what it measures, what the numbers mean, and why it matters more than your weight.
Read article →How Much Protein Per Meal? Why Distribution Beats Total
You can eat the 'right' amount of protein each day and still leave muscle on the table if it's all concentrated in one meal. Here's what the research says about per-meal protein, the leucine threshold, and the practical sweet spot.
Read article →Body Composition vs. BMI: Why the Number on the Scale Isn't the Whole Story
BMI has been the default measure of body weight status for decades — but it was never designed to assess individual health. Here's what body composition actually tells you, and why it matters more.
Read article →BMR vs. TDEE: How to Understand Your Real Calorie Needs
Your basal metabolic rate is what you burn at complete rest. Your total daily energy expenditure is everything you actually burn in a day. Knowing the difference — and how each is calculated — is the foundation of any sensible nutrition plan.
Read article →Visceral Fat: The Hidden Health Risk a Scale Can't See
Two people can weigh the same and look similar, yet carry very different health risks. The difference is often visceral fat — the metabolically active fat packed around your abdominal organs. Here's why it's dangerous and how to estimate it at home.
Read article →Protein After 60: Why the RDA Is Not Enough
The standard protein RDA of 0.8g/kg was designed to prevent deficiency, not preserve muscle mass as you age. Here's what the research says about how much older adults actually need.
Read article →Why Zone 2 Training Is the Most Important Workout You're Probably Not Doing
Zone 2 — the conversational, seemingly easy aerobic pace — turns out to be the training zone most strongly linked to longevity, metabolic health, and fat loss. Here's the science.
