The Body Type Science Theory Research began in 2003 out of necessity. At the time, there was only the genetic scientific Standard Body Type One (BT1) found in any scientifically approved human body anatomy book/resource (defined and recognized by mainstream science and medical doctors). But, no other body types scientifically/medically based on real science with actual scientific definitions backed by real-world scientific data, evidence, and facts.
And, thus, no way to scientifically explain the countless human body shapes worldwide. This includes people who are within their safe Standard BMI (18.5-24.9) but still have too much fat on their bodies; i.e. normal weight obesity (NWO). NWO is a type of skinny fat and directly contradicts the Standard BMI definition that states that once you are within safe Standard BMI you no longer have any excess regular fat (white fat/yellow fat) on your body (therefore, you are the Standard BT1). The other five types of skinny fat (cellulite, thin fat, loose skin, saggy skin, crepey skin) genetically make being normal weight obese possible.
Genetics: Body Composition and Shape (Muscles/Muscle Mass, Skinny Fat, Regular Fat) – Official Scientific Body Type Quiz
Scientifically identifying your unique default genetic body composition helps you better understand why your specific human body is the shape it is and how that affects metabolism, diet, exercise, lifestyle, and weight loss/gain management. How much skinny fat you have on your body where genetically you should have muscle/mass relative to each of the 26 vertebrae — cervical, thoracic, lumbar, sacrum, and coccyx — determines if you are a genetic scientific Standard Body Type One (BT1), Body Type Two (BT2), Body Type Three (BT3), or Body Type Four (BT4). The proprietary Official Scientific Body Type Quiz accurately IDs your specific genetic scientific body type.
- Any part of the human body can be genetically underdeveloped to whatever degree, including muscles/muscle mass – with heritability estimates ranging from 30–85% for muscle strength and 50–80% for lean muscle mass.
- Muscle/mass cannot/does not turn into any kind of fat (regular fat, skinny fat, brown fat, beige fat), that is not how human tissue works.
- Skinny fat (nor any other kind of fat) cannot/does not turn into muscle/mass, that is not how human tissue works.
- Every vertebra (cervical, thoracic, lumbar, sacrum, coccyx) houses a specific set of muscles. If any of those muscles (or related muscles) are genetically underdeveloped, to whatever degree, it directly and negatively affects body composition, shape, posture, and metabolism, no less.
- One (1) pound of muscle burns six (6) calories per day, but one (1) pound of skinny fat and/or regular fat only burns two (2) to three (3) calories daily.
- The more skinny fat and/or regular fat you have on your body, the slower/weaker your metabolism and the fewer calories you burn.
- Anywhere you have skinny fat on your body, the more prone you are to putting on regular fat (which can be both subcutaneous fat and visceral fat) and the harder it is to keep regular fat off (and being overweight or obese/obesity at bay).
- There are a few FDA-approved methods to reduce skinny fat, including surgery, but no amount of dieting, lifestyle, or exercise/time in the gym will fix/get rid of skinny fat or turn skinny fat into muscle/mass. Diet, exercise, and lifestyle can also help reduce and manage skinny fat.
- You cannot permanently change/recomp your genetic body composition, you can only temporarily change/recomposition it through diet, lifestyle, and exercise including weightlifting.
- Once you stop the resistance exercise (like bulking and cutting weight training/lifting) that built any added muscle mass above and beyond your default genetic muscle/mass, inevitably you will gradually begin to lose that added muscle mass and eventually return to your default genetic muscle/mass levels.
- All other body types are unscientific, arbitrary, subjective nonsense including Kibbe, triangle, rectangle, apple, pear, hormones, etc. along with the somatotypes mesomorph, endomorph, and ectomorph body types which were fully debunked and discredited in the 1950s, 70 years ago! Although they can be roughly correlated to a genetic scientific body type.
