Some people have a genetic tendency to gain weight more easily than others. Although genes strongly influence body type and size, the environment also plays a role. People today are gaining weight because of unhealthy food choices like fast food and family habits like eating in front of the TV instead of around a table. High-calorie, low-nutrient snacks and beverages, bigger portions of food, and less-active lifestyles are all contributing to the obesity epidemic.
Sometimes people turn to food for emotional reasons, such as when they feel upset, anxious, sad, stressed out, or even bored.
When this happens, they often eat more than they need. Figuring out if a teen is overweight is a little more complicated than it is for adults. That's because teens are still growing and developing. Doctors and other health care professionals use a measurement called body mass index BMI to tell if someone is overweight. The doctor calculates BMI using a person's height and weight, and then plots that number on a chart.
There are different charts for girls or guys. BMI estimates how much body fat the person has. Because muscle weighs more than fat, a muscular person can have a high BMI, but not too much body fat.
Likewise, it's possible for someone to have a low or ideal BMI but still have too much body fat. Obesity is bad news for both body and mind.
Not only can it make someone feel tired and uncomfortable, carrying extra weight puts added stress on the body, especially the bones and joints of the legs. Kids and teens who are overweight are more likely to develop diabetes and other health problems. And overweight adults have a higher chance of getting heart disease.

Sleep apnea. This condition where a person temporarily stops breathing during sleep is a serious problem for many overweight kids and adults. Sleep apnea can leave people feeling tired and affect their ability to concentrate and learn. It also may lead to heart problems. High blood pressure. Additionally, only around percent of people in the study knew what the low end of the body mass index BMI range for obese was.
People with obesity who did know their BMI, the researchers said, were more likely to classify themselves as obese. Do people not know they are overweight or obese? Or are they in denial about a problem that feels too overwhelming to tackle? Many people who have problems managing their weight may be in denial about what their scale number really means. Likewise, they may have difficulty grasping what a weight issue looks or feels like because reliable indicators are few and far between.
The findings of this study point to a larger problem that doctors and weight-loss experts continue to struggle with when caring for their patients. The measurements and markers for knowing who is overweight or has obesity are difficult to understand, even for people with years of experience.
The experts Healthline interviewed say they hope these methods encourage more individuals to seek help with their weight issues and have an honest discussion with their doctor.

From the perspective of these women, overweight began at a BMI of around 35 - not 25 as the experts say. What is going on here is that the cultural belief of the women as to what "too fat" looks like and therefore what is unhealthy is at odds with what the medical profession thinks.
Elizabeth Lynch, who led the study, said:. The fact that women felt that overweight body sizes were not too fat suggests that being told they are overweight, even by a physician, may not be sufficient motivation for them to attempt to lose weight. The researchers point out that there is a long history of African American women feeling more satisfied with a large body size than non-Hispanic whites. Nonetheless, as people get more and more overweight in the US, Europe and in all other countries too, there is a lesson here.
The researchers suggest that health messages should be accompanied by pictures of what healthy and unhealthy weight actually looks like. It's something we are all losing sight of. So which women are of normal weight?
Numbers 2, 3 and 4. Number 1 has a BMI of 16 and is therefore under-weight.
