From the document that I read about the nature debate on eating disorders, I found out that the nature theory on eating disorders was put forward by biologists.

Biologists look at the body mainly and they are interested in how the body functions affect the mind and behaviour. They also look for causes of behaviour in hormones and neurochemicals.  The main point for the nature debate on eating disorder assumes that the fundamental causes of eating disorders are to be found in some combination of genetics, abnormalities in the structure of the brain and how it works. Biologist tries to prove their evidence by looking at the effect of genes in twins; this study was done by Holland et al 1984. Monozygotic twins share exactly the same genes, while dizygotic twins share an average half of each other’s genetic information.  From Holland et al study, biologist conclude that MZ twins share exactly the same genetic information, therefore if one MZ twin has an eating disorder that is determined entirely genetically, then the other twin must also have it, due to the fact that they both have the same genetic structure. Further researches have been done to support the findings of Holland et al like the study on bulimia by Kendler et al 1991. From Kendler et al study he found out that there are genetic risk factors involved in bulimia nervosa (a form of eating disorder).

Biologist also suggests that eating disorders can be entirely controlled by genetic inheritance. For instant if a mother had an eating disorder and her child had the same disorder, it is said to be inherited. There are also biochemical’s explanations for eating disorders. It is focused on the region of the brain, which is hypothalamus. Hypothalamus is an organ found below the thalamus in the brain. The main points from the document that I read, states that behaviourist believe that all mental/eating disorders, are learnt through our social interactions. Behaviourists are interested mainly in human and animal behaviour in ...
