Healthy Weight Basics: Understanding BMI, Calories and Habits

Healthy weight is influenced by many factors, including nutrition, activity, sleep, genetics, medications and health conditions. No single number defines health.

What Is BMI?

Body mass index, or BMI, is a screening measure based on height and weight. It can be useful for population-level assessment but does not directly measure body fat or overall health.

Calories and Energy Balance

The body uses energy for basic functions and physical activity. Food provides energy, but individual calorie needs vary considerably.

Focus on Sustainable Habits

Balanced meals, regular movement, adequate sleep and realistic routines are generally more sustainable than extreme short-term diets.

Use Health Tools Carefully

Calculators can provide estimates and educational information. They should not be treated as a diagnosis or a personalized medical prescription.

When to Get Professional Guidance

People with significant unintentional weight changes, eating difficulties, chronic conditions or other health concerns should consider individualized professional guidance.
