Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution, although only in a few cases are genes the primary cause of obesity. [4] [5]
The science behind weight management is complex, but one of the key concepts that governs weight management is Energy Balance. [9] Energy Balance is the phrase used to describe the difference between the number of calories a person consumes and the number of calories that same person expends (a.k.a. burns) in a given time period.

Obesity is a medical condition, sometimes considered a disease, [8] [9] [10] in which excess body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over 30 kg / m 2 ...
A metabolic disorder is a disorder that negatively alters the body's processing and distribution of macronutrients, such as proteins, fats, and carbohydrates.Metabolic disorders can happen when abnormal chemical reactions in the body alter the normal metabolic process. [3]
Over 200 genes affect weight by determining activity level, food preferences, body type, and metabolism. [36] Having two copies of the allele called FTO increases the likelihood of both obesity and diabetes. [37] As such, obesity is a major feature of a number of rare genetic conditions that often present in childhood:

A genetic predisposition is a genetic characteristic which influences the possible phenotypic development of an individual organism within a species or population under the influence of environmental conditions. In medicine, genetic susceptibility to a disease refers to a genetic predisposition to a health problem, [1] which may eventually be ...
Medical genetics is the branch of medicine that involves the diagnosis and management of hereditary disorders.Medical genetics differs from human genetics in that human genetics is a field of scientific research that may or may not apply to medicine, while medical genetics refers to the application of genetics to medical care.
