Body Weight Regulation and AnorexiaAccording to data by the U.S. Centers for Disease Control, the
United States has seen a dramatic increase in obesity with all states
having 20% or more of their population being obese (U.S. Obesity
Trends). On the other hand, it is estimated that 8 million Americans
suffer from eating disorders such as anorexia and bulimia (Eating
Disorder Statistics). These two observations point to the prevalence of
body weight concerns in contemporary U.S. culture. Given these facts,
what light do scientific findings shed on the problem of body weight
regulation?For this week’s Discussion you analyze the complex factors that
contribute to body weight. You also assess the biological and cultural
influences related to eating disorders.With these thoughts in mind:PART 1 – WRITE a Post a description of how metabolic rate changes with caloric intake. Then describe at least four influences on body weight. Finally, explain how cultural influences might contribute to eating disorders. Support your postings and responses with specific references to the literature and Learning Resources.Required Resources ReadingsBreedlove, S. M., & Watson, N. V. (2018).

male- or female-typical body. The brain determines the type and amount
of hormones the fetus produces. Furthermore, hormones do not act alone,
but rather in concert with brain regions that regulate sexual
behavior. The brain, therefore, not only regulates sexual behavior, but
it is also shaped by the same hormones that prepare the body for
reproduction. These facts raise intriguing questions about gender,
sexual behavior and orientation, and the extent to which these are, or
are not, under conscious human control.For this Assignment, you research and evaluate the current literature
on prenatal influences on sexual behavior, gender orientation, or
gender typical behavior.The Assignment: Select an article related to the process of sexual differentiation,
prenatal influences on sexual orientation, gender orientation, or
gender typical behavior and write a 2- to 3-page paper that addresses
the following: Write a brief summary of the article you selected. Describe two
implications of the article’s findings. Explain whether the findings
concur or conflict with the body of literature in this area.List one question that remains unanswered and is in need of further research.
