Body Mass Index (BMI) is a measure that converts height and weight using a formula that estimates degree of overweight based on total body mass and related fat mass. It provides a a number that allows you to determine the degree to which your current weight places you at risk for various weight-related medical risks (see below).
Find your BMI in the below table. If you fall in an overweight or obese category then reducing your caloric consumption and increasing physical activity may be desirable. In general, a combined change in consumption (calories in) or expenditure (calories out) will reduce your weight. There is no magic formula like the one you often hear about (reducing 500 calories per day should result in approximately 1 pound of weight loss per week). Not true. How much you lose will depend on many things including your metabolism and physical activity. But nonetheless, reducing calories is what you need to do. So start by reducing 500-1000 calories a day (do not eat less than 1200 calories a day). Eat foods that satisfy you and help you feel full longest. A goal of 1-3 pounds per week weight reduction is reasonable for most people. Everyone is a little different, and measuring food and activity is not exact. Use this information as a starting point and adjust based on average actual weight loss over several weeks.
*Note: Before starting any diet or exercise program, consult a qualified medical provider.
