Understanding Your Health Numbers
A few simple numbers — your weight, height, waist, blood pressure, and how you feel day to day — can tell you a lot about your health. The key is understanding what these figures mean and tracking the right ones over time.
Body Mass and Body Composition
Body Mass Index (BMI) compares your weight to your height and gives a quick screening category: underweight, healthy, overweight, or obese. It is useful as a population-level measure, but it doesn't directly measure body fat, so very muscular people can show a misleadingly high BMI. Combining BMI with waist measurement and how you feel is more meaningful.
Energy In, Energy Out
Weight change follows a simple principle: eat more energy than your body uses and you gain; eat less and you lose. Your body's daily energy needs depend on age, sex, height, weight, and activity. Sustainable changes — modest adjustments to food and daily movement — work far better than extreme diets.
Build Habits That Last
- Move regularly — short daily activity beats occasional intense sessions
- Sleep seven to nine hours; poor sleep disrupts appetite and energy
- Drink water throughout the day and eat a variety of whole foods
- Weigh yourself weekly, not daily, and watch trends rather than single readings
