Body image
Body image is a person's perception of the aesthetics or sexual attractiveness of their own body. The phrase "body image" was first coined by the Austrian neurologist and psychoanalyst Paul Schilder in his book "The Image and Appearance of the Human Body" (1935). Human society has at all times placed great value on beauty of the human body, but a person's perception of their own body may not correspond to society's standards. The concept of body image is used in a number of disciplines, including psychology, medicine, psychiatry, psychoanalysis, philosophy and cultural and feminist studies. The term is also often used in the media.
The Biggest Loser (season 16)
The Biggest Loser: Glory Days is the sixteenth season of "The Biggest Loser" which premiered on September 11, 2014 on NBC.

This season, the contestants are all former athletes including former National Football League players and Olympic Gold medalists. The contestants competed to win a $250,000 prize which was awarded to Toma Dobrosavljevic, the contestant with the highest percentage of weight loss. This season was also the last for host Alison Sweeney to focus on other projects.
Weight loss
Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue. Weight loss can either occur unintentionally due to malnourishment or an underlying disease or arise from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition.
Management of obesity
Management of obesity can include lifestyle changes, medications, or surgery. The main treatment for obesity consists of dieting and physical exercise. Diet programs may produce weight loss over the short term, but maintaining this weight loss is frequently difficult and often requires making exercise and a lower calorie diet a permanent part of an individual's lifestyle. Success rates of long-term weight loss maintenance with lifestyle changes are low, ranging from 2 to 20%. Dietary and lifestyle changes are effective in limiting excessive weight gain in pregnancy and improve outcomes for both the mother and the child.
Adjustable gastric band
A laparoscopic adjustable gastric band, commonly called a lap-band, A band, or LAGB, is an inflatable silicone device placed around the top portion of the stomach to treat obesity, intended to slow consumption of food and thus reduce the amount of food consumed. Adjustable gastric band surgery is an example of bariatric surgery designed for obese patients with a body mass index (BMI) of 40 or greater—or between 35 and 40 in cases of patients with certain comorbidities that are known to improve with weight loss, such as sleep apnea, diabetes, osteoarthritis, GERD, hypertension (high blood pressure), or metabolic syndrome, among others.
Obesity
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health. People are generally considered obese when their body mass index (BMI), a measurement obtained by dividing a person's weight by the square of the person's height, is over , with the range defined as overweight. Some East Asian countries use lower values. Obesity increases the likelihood of various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, osteoarthritis and depression. Obesity is most commonly caused by a combination of excessive food intake, lack of physical activity, and genetic susceptibility.
Body mass index
The body mass index (BMI) or Quetelet index is a value derived from the mass (weight) and height of an individual. The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m, resulting from mass in kilograms and height in metres. The BMI may also be determined using a table or chart which displays BMI as a function of mass and height using contour lines or colours for different BMI categories, and which may use other units of measurement (converted to metric units for the calculation). The BMI is an attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, and then categorize that person as "underweight", "normal weight", "overweight", or "obese" based on that value.
