Does obesity occur in nature?
Obesity isn't just something that affects domestic animals, though. Wild animals fatten up, too, but it's usually in relation to seasonal cycles and food availability: they've learned to eat when food is plentiful.

Is obesity biological or environmental?
In reality, obesity is a multifactorial disease (3) that is caused by a combination of biological, genetic, social, environmental, and behavioral determinants.
Is obesity caused by environmental factors?
Behavior, environment, and genetic factors all have a role in causing people to be overweight and obese. Obesity results from the energy imbalance that occurs when a person consumes more calories than their body burns.

A variety of factors such as behavior, environment, genetics, and sleep patterns may have an effect in causing people to have overweight and obesity.
What is obesity in medical terms?
Describe obesity as a mild state of chronic inflammation of adipose tissue.
Where does resistin come from?
In rodents, resistin production can come from both macrophages and adipocytes. [37] Fukuhara et al. identified a new novel adipose tissue cytokine called visfatin.[38] This cytokine is a protein mediator secreted by fat cells (high levels of expression in visceral fat cells), which acts like the enzyme nicotinamide phosphoribosyltransferase (Nampt), which is involved in the NAD+ salvage pathway. Initially, it was identified as a Pre- B cell Colony Enhancing Factor (PBEF) secreted by human peripheral blood lymphocytes.[39] Visfatin has an insulin-mimetic effect originally discovered in the liver, skeletal muscle, and bone marrow as a growth factor for B lymphocyte precursors. [40]
Which hormone is secreted by adipose tissue?
Leptin , a hormone that plays a role in appetite and energy balance regulation, along with pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha), are secreted by adipose tissue cells.[32] Leptin is secreted in proportion to the amount of fat stored in adipose tissue. Another hormone secreted by adipose tissue is adiponectin, which decreased in proportion to fat storage in the body. [33]
Why is it important to understand the pathophysiology of obesity?
Having a better understanding of the pathophysiology of obesity is important to all the health professionals involved in curbing obesity. To manage and prevent obesity requires an interprofessional healthcare team to be involved in patient management, such as physicians, nurses, nutritionists, dieticians, and exercise physiologists.
Is the Visceral Adiposity Index more sensitive than the BMI?
Compared to the Body Mass Index (BMI), the Visceral Adiposity Index (VAI) is a more specific and sensitive examination tool. The VAI is, therefore, a reliable indicator of increased patient risk for cardiometabolic diseases. [6][7] There is currently a lack of scientific knowledge regarding the biochemical and physiologic mechanisms associated with this. A possible explanation for the increased specificity and sensitivity of the VAI is that visceral fat has direct access to the portal venous system, whereas subcutaneous white adipose tissue does not. [8]
What is NCBI bookshelf?
NCBI Bookshelf. A service of the National Library of Medicine, National Institutes of Health.
Which organ system maintains metabolic homeostasis?
Multiple organ systems maintain metabolic homeostasis. Adipose tissue and muscles are a few of them. Adipocytes secrete hormones/chemicals known as adipokines which act on multiple cells or organs to regulate metabolism. Further research needs to be done to understand better the concentrations of these hormones in different populations, including elderly and overweight/obese people, and the role these hormones play in obesity.
Why do some people have no choice?
Some people have no choice because it’s in their genes. Obesity tends to run in families, meaning that it may have a genetic cause. However, family members share not only genes but also diet and lifestyle habits that may contribute to obesity.Separating these lifestyle factors from genetic ones is often difficult.
Why do people have obesity?
So as you can see, Obesity is the result of high diets and putting taste before health. Also that they eat a lot and don’t exercise enough. But it is also the result of genetic make up. The human body controls the weight of the thin people with the same basic equipment as it does with fat people.
Why do people eat so much?
Psychological factors also may influence eating habits. Many people eat in response to negative emotions such as boredom, sadness, or anger .Most overweight people have no more confusion than normal weight people, about 30 percent of the people who seek treatment for serious weight problems have difficulties with binge eating. So as you can see, Obesity is the result of high diets and putting taste before health.
Does heredity contribute to obesity?
Still, growing evidence points to heredity as a strong determining factor of obesity. In one study of adults who were adopted as children, researchers found that the subjects’ adult weights were closer to their biological parents’ weight than their adoptive parents’.
Is obesity a disease?
Obesity is a disease or condition that is caused by both Nature and Nurture. In this essay you will read examples and facts that show that obesity is the result of family genes, and through your own personal satisfaction, or decisions.
Does the environment affect obesity?
The environment provided by the adoptive family apparently had less influence on the development of obesity than the person’s genetic makeup. Although genes are an important factor in many cases of obesity, a person’s environment also plays a very important part.Environment includes lifestyle behaviors such as what a person eats and how active he or she is. Americans tend to have high-fat diets.
Is heredity a factor in obesity?
Still, growing evidence points to heredity as a strong determining factor of obesity. In one study of adults who were adopted as children, researchers found that the subjects’ adult weights were closer to their biological parents’ weight than their adoptive parents’.
Food, Activity, and Sleep
- Eating and physical activity patterns, insufficient sleepand several other factors influence excess weight gain.
Social Determinants of Health
- The conditions in which we live, learn, work, and play are called social determinants of health (SDOH). It can be difficult to make healthy food choices and get enough physical activity if these conditions do not support health. Differences in SDOH affect chronic disease outcomes and risks, including obesity, among racial, ethnic, and socioeconomic groups as well as in different geogra…
Genetics
- Genetic changes in human populations occur too slowly to be responsible for the obesity epidemic. Yet variants in several genes may contribute to obesity by increasing hunger and food intake. Rarely, a specific variant of a single gene (monogenic obesity) causes a clear pattern of inherited obesity within a family.,
Illnesses and Medications
- Some illnesses, such as Cushing’s disease, may lead to obesity or weight gain. Drugs such as steroids and some antidepressants may also cause weight gain. Research continues on the role of other factors such as chemical exposures and the role of the microbiome.
