Human energy regulation is primed to protect against weight loss, rather than to control weight gain. The global incidence of obesity has tripled in the past four decades as a result of changes in our environment—the physical, social, political, and economic factors that influence how much we eat and move. Inthis number grew to eight monogenic genes and four polygenic genes.

Public health efforts to prevent obesity focus on strategies that promote healthy eating and encourage physical activity. Survey questions included items such as age, demographics, ethnicity, existing health conditions, physical activity, alcohol consumption, and smoking status, along with quality of life. This regulatory system can counteract voluntary efforts to lose weight and maintain a healthy body weight by the activation of compensatory biological influences such as increased appetite or decreased metabolic rate. Polygenic obesity, on the other hand, the more common form of obesity, refers to obesity that is caused by the combined effect of multiple genetic variants.
