Question 3

Briefly describe the inside-the-body theories explaining obesity.

Accepted Answer

The brain and other organs constantly monitor and respond to slight fluctuations in the body's internal conditions, such as blood glucose, blood pH, and body temperature and maintain them within narrow physiological ranges. The set-point theory of obesity holds that, to a degree, this may also explain why people so easily regain lost weight. After weight loss, the body adjusts its metabolism somewhat in the direction of restoring the original weight. Another factor is thermogenesis. The body's working enzymes normally "waste" a small percentage of energy as heat in a process called thermogenesis. Some enzymes expend copious energy in thermogenesis, producing heat but performing no other useful work. As more heat is radiated away from the body, more calories are spent, and fewer calories are available to be stored as body fat. One tissue extraordinarily gifted in thermogenesis is brown adipose tissue (BAT), a well-known heat-generating tissue of animals and human infants that has been identified in human adults, too. People with the greatest body fatness appear to have the least BAT activity. Additionally, researchers are probing the possibility that certain strains of intestinal bacteria may affect body weight. Bacteria may generate signals that alter adipose tissue, changing its metabolic efficiency. Also, some intestinal bacteria, or compounds they produce, may generate signals that help the brain regulate the appetite. Also, genes play an important role in causing obesity. Genes carry the instructions for making enzymes and enzymes control energy metabolism. Any variation in these genes might be a potential factor as for why some people get fat easily and some stay lean. Geneticists have identified more than 100 genes that are likely to play roles in obesity development by altering metabolism. Therefore, it is evident that inherited genes definitely influence body weight.
