What Every Body Type ACTUALLY Looks Like (And The Fix)
In a Nutshell
Four body types—skinny (low muscle/fat, high activity burns 4k+ cals/day), skinny fat (normal weight but soft, low muscle from poor training), bulky (high muscle but 20-30%+ fat, burns more via muscle), high fat (30-50%+ fat, highest metabolisms at 3k+ cals/day)—were tested via DEXA, strength, and doubly labeled water for exact metabolism and intake, revealing no "slow" metabolisms but underestimation of calories eaten. Skinny: eat surplus + 3x/week full-body lifts for 10-15lbs muscle gain. Skinny fat: recomposition with hard weights, 0.5-1lb/week deficit, 0.8g/lb protein. Bulky: track food precisely for 400-700cal deficit to 15% fat. High fat: aggressive 2-4lb/week deficits with easy swaps, leveraging high burns for fast results without muscle loss.

You probably fall into one of these four body types. Men and women of completely different body types were brought in, their exact muscle and fat levels measured, and the world's most accurate metabolism test used to find out calories burned and eaten. Subjects eat specific calories per day. By the end, you'll know your body type, why your body works the way it does, and the simple training and diet approach it needs.
Aaron is very lean at 13% body fat, but total muscle mass below average. He has a hard time sitting still. Skinny physique is naturally lean, slender look with smaller frame, low muscle mass, less fullness in shoulders, arms, and legs. Speaker started with this body type, played sports as a kid, ate whatever without gaining weight, but lifting was slow to change body. Maria weighs 97 lbs, goal to build strength, mainly upper body arms, feel stronger. Low muscle mass means both struggled in strength tests. Maria's number 5.09, below 5.45 risks sarcopenia (age-related muscle loss). Her DEXA shows bone density lower than 72% of others her age, greater fracture risk as she ages. Health risks differ by body type, even if looking fit and healthy. Prevention plans for each at end.
In clothes, looks similar to skinny, but softer physique with excess fat around belly and love handles. David's experience: moved to California, started gaining weight. Average person gains 1-2 lbs yearly; without lifting properly, stored as fat, common especially younger. Can be leaner end like Dennis and Grace, or more body fat. All have below average muscle mass via fat-free mass index (FFMI): lean mass (body weight minus fat) divided by height squared. Average FFMI men 18, women below 16.
