One gene or many? Rarely, obesity occurs in families according to a clear inheritance pattern caused by changes in a single gene. The most commonly implicated gene is MC4R, which encodes the melanocortin 4 receptor.
The strength of the genetic influence on weight disorders varies quite a bit from person to person. Research suggests that for some people, genes account for just 25% of the predisposition to be overweight, while for others the genetic influence is as high as 70% to 80%.
Rarely, a clear pattern of inherited obesity within a family is caused by a specific variant of a single gene (monogenic obesity). Most obesity, however, probably results from complex interactions among multiple genes and environmental factors that remain poorly understood (multifactorial obesity).
A child with one obese parent has a 50 percent chance of being obese. When both parents are obese, their children have an 80 percent chance of obesity. Many genetic and environmental factors contribute to the number of calories people eat and burn up, which is why weight loss and gain varies for different people.
A main cause of childhood obesity is the behavior children pick up from their parents and caregivers. You can prevent childhood obesity by teaching your child about healthy eating habits and encouraging them to stay physically active.
Chances of a child become obese increases if one or both parents or obese or suffered from it at a young age. A good parenting tip will be to teaching the child to eat a healthy diet and constantly monitoring the BMI will help you spot a problem if one were to rise.
A genetic predisposition to obesity can be overcome, in part, by having a physically active lifestyle.
Genes and behavior may both be needed for a person to be overweight. In some cases, multiple genes may increase one's susceptibility for obesity and require outside factors such as abundant food supply or little physical activity.

Factors like age, decreased activity levels, loss of muscle mass, a slower metabolism, and even your menstrual cycle can all cause you to gain a few extra pounds. So unexplained weight gain isn't always something to worry about, especially if you can pinpoint the reason after thinking about it for a few minutes.
Is it possible to be overweight and healthy? Silvana Pannain, MD: Yes, you can be overweight and metabolically healthy. At the same time, we know that obesity is a disease that affects the body in many different ways. Thirteen types of cancer and 200 other health conditions are related to obesity.
Obesity is a chronic disease. According to the Centers for Disease Control and Prevention, obesity affects 42.8% of middle-age adults. Obesity is closely related to several other chronic diseases, including heart disease, hypertension, type 2 diabetes, sleep apnea, certain cancers, joint diseases, and more.
While being overweight is a precursor to obesity and, like obesity, can increase the risk of diabetes, heart attack and stroke, it's also possible to be overweight and still healthy, especially if you're free from chronic diseases like hypertension or diabetes.
The medical term for 'skinny fat' is technically MONW or “metabolically obese, normal weight” and “Sarcopenic obesity”. Skinny fat people are often a normal weight (or underweight!) but because of their sedentariness, lack of muscle, or poor diet, they have a high percentage of body fat.
Fat shaming is described as the physical act of humiliating someone due to their excess weight, or them being obese. Fat shaming and weight bias are a direct result of misinformation that culture has about a healthy body weight.
One gene or many? Rarely, obesity occurs in families according to a clear inheritance pattern caused by changes in a single gene. The most commonly implicated gene is MC4R, which encodes the melanocortin 4 receptor.
Reducing calories and practicing healthier eating habits are vital to overcoming obesity. Although you may lose weight quickly at first, steady weight loss over the long term is considered the safest way to lose weight and the best way to keep it off permanently.
"Reducing belly fat takes a combination approach of a low-calorie diet that is high in fiber and low in (refined) carbohydrates and sugar along with cardiovascular and weight training," said Dr. Kashyap. "If you are willing to do the work, you can move past genetics and lose it."
Causes of obesity in children include unhealthy food choices, lack of physical activity and family eating habits. This rise in the number of overweight children is disturbing, because it causes health problems and can lead to social problems.
If your BMI is 25.0 to <30, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obesity range.
Although a range of parental feeding behaviours, such as breastfeeding, formula feeding, timing and type of solid foods introduced, parental control in feeding, parental pressure to eat or restriction in feeding [24–26] have been linked with excessive weight gain in children [27–30], most existing research has focused ...
3 Those who were underweight had the highest risk of both short-term and long-term mortality (over three years). Those who were overweight or obese had a lower risk of short-term and long-term mortality compared with those who had a BMI in the normal-weight range.
