Summary


Obesity is a condition that the body weight and body fat are greater than what is proposed as healthy for you given height. BMI is a way to check the amount of body fat, it may not always be a very accurate. Obesity is declared when having a BMI greater than thirty. Having a fairly high BMI can be serious health hazard. Obesity it associated with high blood pressure, osteoarthritis, diabetes, heart disease, respiratory problems, and some forms of cancer. Lately, in the past couple of decades, majority of the adults in the United States are over weight and over thirty percent are listed as obese. Not only adults are listed obese but children as well. About fifteen percent of children and adolescents are obese. Which would lead to the increase of the incidence of health problems that were once rare among children. Genes have a strong argument against obesity. There’s evidence that seventy to eight percent among individuals in body fatness is due to genetic related factors. For instance, a small percentage of people have a genetic mutation that affects the melanocortin 4 receptor (MC4R). MC4R is a receptor in the brain that receives signals to regulate appetite through the hormone leptin. This genetic mutation changes the surface of MC4R so that it is unable to process the message to control hunger. As a result, people with an MC4R mutation are more susceptible to obesity because their brains don’t receive the signal to suppress the urge to eat. With no signal to tell them that they are full, they continue to feel hungry even after their body no longer needs additional energy.
