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]
Details on the study on fat cells and weight management The study involved a comprehensive measurement of cell volume and the number of fat cells in abdominal fat in samples from 260 participants.
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. [9]
Set point theory can be construed as implying weight regulation in a wide or tight range around the set point, in a symmetric or in an asymmetric manner (i.e. treating weight gain and loss either the same or differently), and may apply to regulation of body fat levels specifically (in a multi-compartment model) or to overall body weight.
In medicine, genetic susceptibility to a disease refers to a genetic predisposition to a health problem, [1] which may eventually be triggered by particular environmental or lifestyle factors, such as tobacco smoking or diet. Genetic testing is able to identify individuals who are genetically predisposed to certain diseases.
Attitudes toward body weight held by people in one's life may also play a role in obesity. A correlation in BMI changes over time has been found among friends, siblings, and spouses. [153] Stress and perceived low social status appear to increase risk of obesity. [152] [154] [155] Smoking has a significant effect on an individual's weight.
Risk factors are divided into three categories; genetic, environmental and complex factors (for example overweight). Genetic risk factors are associated with the permanent changes in the base pair sequence of human genome. In the last decade, many studies have been generated data regarding genetic basis of multifactorial diseases.
Other gastrointestinal symptoms of anxiety, for example, are nausea and constipation. All things considered, the dynamic between stress and hunger cues can be complex. Let’s get into the nitty ...
