Somatotyping is a system for classifying human physiques into three main types—ectomorph (thin/linear), mesomorph (muscular/athletic), and endomorph (round/soft)—based on relative body composition, developed by William Sheldon in the 1940s. While originally linked to personality, the modern use of somatotyping focuses on body shape for fitness and health, recognizing that most people are a mix of these types, not just one extreme.

What is somatotyping in criminology?

What are the three types of somatotypes?

Body type, or somatotype, refers to the idea that there are three generalized body compositions that people are predetermined to have. The concept was theorized by Dr. W.H. Sheldon back in the early 1940s, naming the three somatotypes endomorph, mesomorph, and ectomorph.

What foods should a mesomorph avoid?

Mesomorphs should avoid processed foods, sugary drinks, refined grains, and excessive saturated/trans fats, focusing instead on lean proteins, whole carbs, fruits, and veggies to manage their natural tendency to gain fat despite being naturally athletic, as overconsumption of unhealthy items leads to fat gain. Key foods to limit or avoid include soda, candy, white bread, fried foods, bacon, chips, and processed meats.

The most unhealthy body shape is generally considered the apple shape, where fat accumulates around the midsection (belly), indicating dangerous visceral fat that surrounds organs and significantly increases risks for heart disease, type 2 diabetes, metabolic syndrome, and certain cancers, even in people with a normal weight. This abdominal fat is more metabolically active and dangerous than subcutaneous fat found in pear-shaped bodies (hips/thighs). 

Which race is most muscular?

How does age affect female body type?

As women age, their bodies experience a shift of body fat distribution towards the torso, increased adipose tissue, decreased muscle mass, and changes in skin coloration, firmness, and elasticity (Evans &Lexell, 1995;Situm, Buljian, Cavka, Bulat, Krolo, Lugovic, 2010; Tchkonia et al., 2010).

How do I check what body type I am?

Use an online calculator or simply observe your natural proportions in a mirror to see how your bust, waist, and hips relate to each other.
