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.
Obesity in the United States
Obesity in the United States has been increasingly cited as a major health issue in recent decades, resulting in diseases such as coronary heart disease that lead to mortality. While many industrialized countries have experienced similar increases, obesity rates in the United States are the highest in the world. Obesity has continued to grow within the United States. Two of every three American men are considered to be overweight or obese, but the rates for women are far higher. The United States contains one of the highest percentage of obese people in the world. An obese person in America incurs an average of $1,429 more in medical expenses annually.
Childhood obesity
Childhood obesity is a condition where excess body fat negatively affects a child's health or well-being. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health concern. The term overweight rather than obese is often used in children as it is less stigmatizing. Body mass index (BMI) is acceptable for determining obesity for children two years of age and older. It is determined by the ratio of weight to height.
Human nutrition
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and health. Generally, people can survive up to 40 days without food, a period largely dependent on the amount of water consumed, stored body fat, muscle mass and genetic factors. Poor nutrition is a chronic problem often linked to poverty, a poor understanding of nutrition and dietary practices, and deficient sanitation and food security. Malnutrition and its consequences are large contributors to deaths and disabilities worldwide. Good nutrition helps children grow physically, promotes human biological development and helps in the eradication of poverty.
Obesity and the environment
Obesity and the environment aims to look at the different environmental factors that have been determined by researchers to cause and perpetuate obesity. Studies have shown that obesity has become increasingly prevalent in both people and animals such as pets and laboratory animals. There have been no linkages found between this obesity trend and diet and exercise. According to Professor Robert H. Lustig from the University of California, San Francisco, "[E]ven those at the lower end of the body mass index (BMI) curve are gaining weight. Whatever is happening is happening to everyone, suggesting an environmental trigger."
Abdominal obesity
Abdominal obesity, also known as central obesity, is when excessive abdominal fat around the stomach and abdomen has built up to the extent that it is likely to have a negative impact on health. There is a strong correlation between central obesity and cardiovascular disease. Abdominal obesity is not confined only to the elderly and obese subjects. Abdominal obesity has been linked to Alzheimer's disease as well as other metabolic and vascular diseases. Visceral and central abdominal fat and waist circumference show a strong association with type 2 diabetes. Visceral fat, also known as organ fat or "intra-abdominal fat", is located inside the peritoneal cavity, packed in between internal organs and torso, as opposed to subcutaneous fat, which is found underneath the skin, and intramuscular fat, which is found interspersed in skeletal muscle.
Obesity in the Middle East and North Africa
Obesity in North Africa and the Middle East is a notable health issue. In 2005, the World Health Organization measured that 1.6 billion people were overweight and 400 million were obese. It estimates that by the year 2015, 2.3 billion people will be overweight and 700 million will be obese. The Middle East, including the Arabian Peninsula, Eastern Mediterranean, Turkey and Iran, and North Africa, are no exception to the worldwide increase in obesity. Subsequently, some call this trend the New World Syndrome. The lifestyle changes associated with the discovery of oil and the subsequent increase in wealth is one contributing factor.

Do they actually say "grossly overweight"?  That seams a little mean.  I know that obesity is very bad for your health though, that is why I became a vegan.  Is diet the best way to lose weight?

Some use the term "grossly overweight". But it is a condition in which excess body fat has accumulated to the extent that it may have a negative effect on health. A combination of diet and exercise are the best way to lose weight/fat mass, but diet alone is a good method.

Childhood obesity in Australia
Obesity is defined as the excessive accumulation of fat and is predominantly caused when there is an energy imbalance between calorie consumption and calorie expenditure. Childhood obesity is becoming an increasing concern worldwide, and Australia alone recognizes that 1 in 4 children are either overweight or obese. For Australians aged between 4 and 17 years, obesity is a very concerning condition as once gained it is favourably harder to be liberated from. Short-term effects on children can mean a decrease in their psychological well-being (stigmatisation and poor self-esteem) as well as physical deteriorations such as sleep apnea, breathlessness and cardiovascular disease.
Cat food
Cat food is food for consumption by cats. Cats have specific requirements for their dietary nutrients. Certain nutrients, including many vitamins and amino acids, are degraded by the temperatures, pressures and chemical treatments used during manufacture, and hence must be added after manufacture to avoid nutritional deficiency. The amino acid taurine, for example, which is found in meat, is degraded during processing, so synthetic taurine is normally added afterwards. Long-term taurine deficiency may result in retinal degeneration, loss of vision, and cardiac arrest. The idea of preparing specialized food for cats came later than for dogs (see dog biscuits and dog food).

Leptin
Leptin (from Greek λεπτός "leptos", "thin"), "“the hormone of energy expenditure”", is a hormone predominantly made by adipose cells that helps to regulate energy balance by inhibiting hunger. Leptin is opposed by the actions of the hormone ghrelin, the "hunger hormone". Both hormones act on receptors in the arcuate nucleus of the hypothalamus to regulate appetite to achieve energy homeostasis. In obesity, similar to resistance of insulin in type 2 diabetes, a decreased sensitivity to leptin occurs, resulting in an inability to detect satiety despite high energy stores. Although regulation of fat stores is deemed to be the primary function of leptin, it also plays a role in other physiological processes, as evidenced by its multiple sites of synthesis other than fat cells, and the multiple cell types beside hypothalamic cells that have leptin receptors.
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.

That is good to know.  What should I start exercising as well?
0_Wizard
It's always a good idea to incorporate exercise into your weekly routine at least 3 times a week for 30-40 minutes a day! It offers many more benefits than weight loss, such as mood improvement and higher energy levels.

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. Bob Harper and Dolvett Quince returned as trainers, while Jillian Michaels decided to leave the show. There are two new trainers this season: Jessie Pavelka and Jennifer Widerstrom. 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.
Strength training
Strength training is a type of physical exercise specializing in the use of resistance to induce muscular contraction which builds the strength, anaerobic endurance, and size of skeletal muscles. When properly performed, strength training can provide significant functional benefits and improvement in overall health and well-being, including increased bone, muscle, tendon, and ligament strength and toughness, improved joint function, reduced potential for injury, increased bone density, increased metabolism, increased fitness and improved cardiac function. Training commonly uses the technique of progressively increasing the force output of the muscle through incremental weight increases and uses a variety of exercises and types of to target specific muscle groups.
The Biggest Loser (season 7)
The Biggest Loser: Couples 2 is the seventh season of the NBC reality television series "The Biggest Loser". The season premiered on January 6, 2009, with eleven overweight couples competing for a cash prize of $250,000. Alison Sweeney is featured as the host, with trainers Bob Harper and Jillian Michaels. Helen Phillips won the competition with a total weight loss percentage of 54.47%. Total Votes counts only votes that are revealed at elimination. The total doesn't count unrevealed votes (if the contestant has already received the require number of votes needed to be eliminated). Contestants are listed in chronological order of elimination.
Energy level
A quantum mechanical system or particle that is bound—that is, confined spatially—can only take on certain discrete values of energy. This contrasts with classical particles, which can have any energy. These discrete values are called energy levels. The term is commonly used for the energy levels of electrons in atoms, ions, or molecules, which are bound by the electric field of the nucleus, but can also refer to energy levels of nuclei or vibrational or rotational energy levels in molecules. The energy spectrum of a system with such discrete energy levels is said to be quantized. In chemistry and atomic physics, an electron shell, or a principal energy level, may be thought of as an orbit followed by electrons around an atom's nucleus.
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.
Well-being contributing factors
Well-being is a much-studied topic in psychology, especially positive psychology. Related concepts are eudaimonia, happiness, flourishing, quality of life, contentment, and meaningful life. Central theories are Diener's tripartite model of subjective well-being, Ryff's Six-factor Model of Psychological Well-being, Corey Keyes' work on flourishing, and Seligmann's contributions to positive psychology and his theories on "authentic happiness" and P.E.R.M.A. Positive psychology is concerned with eudaimonia, "the good life" or flourishing, living according to what holds the greatest value in life – the factors that contribute the most to a well-lived and fulfilling life.
