Body Mass Index A numerical value derived from weight and height, used as a quick, inexpensive indicator of weight-related health risk. BMI Categories Classifications based on BMI values: underweight, healthy weight, overweight, and obese, each linked to different health risks. Body Composition The relative proportions of lean mass and fat mass in the body, providing a more accurate health assessment than BMI alone. Lean Body Mass All body components except fat, including muscle, bone, organs, and water; often the focus for fitness improvements. Fat Body Mass The total amount of adipose tissue in the body, with higher levels linked to increased risk of chronic diseases. Visceral Fat Fat stored around internal organs in the torso, strongly associated with central obesity and elevated disease risk. Subcutaneous Fat Fat located beneath the skin but above muscle, often referred to as 'pinchable' fat and less risky than visceral fat. Central Obesity Excess fat accumulation around the midsection, often linked to higher levels of visceral fat and greater health risks. Apple Distribution A body shape characterized by more fat around the abdomen, associated with higher central obesity and disease risk. Pear Distribution A body shape with more fat on the hips and thighs, typically linked to lower central obesity and reduced health risk. Waist Circumference A measurement around the smallest part of the waist, used to assess central obesity and related health risks. Skin Fold Test A method using calipers to measure the thickness of subcutaneous fat at various body sites to estimate body fat percentage. Bioelectrical Impedance A technique that estimates body fat by measuring how easily a low-level electrical current passes through the body. Underwater Weighing A method comparing body weight in and out of water to determine body composition based on tissue density differences. Dual X-ray Absorptiometry A highly accurate scan using low-level x-rays to differentiate and measure bone, lean tissue, and fat in the body.
