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]
Other critics suggest that race itself may affect the way obesity presents itself in individuals. In a recent study of 70,000 men and women of African ancestry, researchers found three new common genetic variants. [14] These single-nucleotide polymorphisms (SNPs) are connected to body mass index (BMI) and obesity. Therefore, individuals who ...
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]
Dr. Robert Lufkin says he taught lies in medical school about weight loss, diet, high blood pressure, and statins to prevent heart disease. Experts respond.
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:
Weight loss is a personal for everyone, so it’s hard to say that you’ll drop pounds just by having more protein and fiber in your diet. However, eating both may help you feel fuller for longer.
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 short, getting proper sleep is an important support for weight loss programs and other methods of weight management. Fortunately, there are ways to try to get a full night of sleep, from better ...
