Some children are at greater risk for obesity because of genetic factors. They have inherited genes from their parents that make their bodies gain weight easily. This would have been a very good trait hundreds of years ago, when food was hard to find and people were very active.
How do genetics affect obesity?
Science shows that genetics plays a role in obesity. Genes can directly cause obesity in specific disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. However genes do not always predict future health. Genes and behavior may both be needed for a person to be overweight.
How much of childhood obesity is genetic?
New research suggests that about 35 to 40 percent of a child’s weight predisposition is inherited from mom and dad. In some cases of childhood obesity, the genetic impact may be as high as 55 to 60 percent.
Why are parents the cause of childhood obesity?
Children whose parents or other family members are overweight or obese are more likely to follow suit. But the main cause of childhood obesity is a combination of eating too much and exercising too little. A poor diet containing high levels of fat or sugar and few nutrients can cause kids to gain weight quickly.
Is obesity caused by genetics or lifestyle?
Neither genes nor lifestyle are responsible for widespread obesity. Instead, it may be entirely down to our environment during childhood. Scientists have long agreed that obesity is not only a result of eating too much or sitting down for too long.
Can genetic obesity be cured?
Experts: Obesity Is Biologically ‘Stamped In,’ Diet and Exercise Won’t Cure It. New research into the biological mechanisms of obesity suggests eating less and exercising more aren’t enough for people with long-term weight problems.
How can we prevent genetic obesity?
A genetic predisposition to obesity can be overcome, in part, by having a physically active lifestyle. Writing in the American Journal of Clinical Nutrition, Vimaleswaran and co-investigators show that physical activity attenuates the BMI-increasing effects of an FTO (fat mass and obesity-associated) risk allele.
Are parents to blame for childhood obesity?
Pointing the finger of blame at parents for children’s weight gain may be unfair, research suggests. It has been thought that parents’ feeding patterns are a major factor in whether a child is under or overweight.
How can we prevent childhood obesity?
The most important strategies for preventing obesity are healthy eating behaviors, regular physical activity, and reduced sedentary activity (such as watching television and videotapes, and playing computer games).
Why is my child gaining so much weight?
Causes of weight problems and obesity in children
Most cases of childhood obesity are caused by eating too much and exercising too little. Children need enough food to support healthy growth and development. But when they take in more calories than they burn throughout the day, it can result in weight gain.
Where is child obesity most common?
Among children 10 to 19, Nauru still appears to have the highest obesity rate at 31.7%, followed by the Cook Islands at 30.3%, Palau at 29.4%, Niue at 27.6%, Tuvalu at 25.3%, Tonga at 24.9% and the Marshall Islands at 24.4%, according to WHO data from 2016.
How can obesity be prevented and treated?
- Exercise regularly. You need to get 150 to 300 minutes of moderate-intensity activity a week to prevent weight gain. …
- Follow a healthy-eating plan. …
- Know and avoid the food traps that cause you to eat. …
- Monitor your weight regularly. …
- Be consistent.
Who is most at risk for childhood obesity?
Children at risk of becoming overweight or obese include children who:
- have a lack of information about sound approaches to nutrition.
- have a lack of access, availability and affordability to healthy foods.
- have a genetic disease or hormone disorder such as Prader-Willi syndrome or Cushing’s syndrome.
What are the behavioral causes of obesity?
A number of behavioural risk factors has been postulated, including diets with a high energy density, high consumption of sugar-sweetened beverages, large portion sizes, eating patterns, high levels of sedentary behaviour and low levels of physical activity.
Who obese people?
Obesity is defined as excessive body fat that increases your risk of other health problems. A person with a body mass index (BMI) above 30 is considered obese, while a person with a BMI between 25 and 30 is considered overweight.
