The most common causes of Obesity or Weight Gain as well as Over Weight.
Obesity is a complex disorder involving an excessive amount of body fat. Obesity isn't just a cosmetic concern. Although there are genetic, behavioral, and hormonal influences on body weight, obesity occurs when you take in more calories than you burn through exercise and normal daily activities. Your body stores these excess calories as fat.
Obesity is diagnosed when your body mass index (BMI)
is 30 or higher. Your body mass index is calculated by dividing your weight in kilograms (kg) by your height in meters (m) squared.
| BMI | Weight status |
|---|---|
| Below 18.5 | Underweight |
| 18.5-24.9 | Normal |
| 25.0-29.9 | Overweight |
| 30.0-34.9 | Obese (Class I) |
| 35.0-39.9 | Obese (Class II) |
| 40.0 and higher | Extreme obesity (Class III) |
For most people, BMI provides a reasonable estimate of body fat. However, BMI doesn't directly measure body fat, so some people, such as muscular athletes, may have a BMI in the obese category even though they don't have excess body fat. Ask your doctor if your BMI is a problem.
When you're obese, your overall quality of life may be diminished.
You may not be able to do things you used to do, such as participating in enjoyable activities. You may avoid public places. Obese people may even encounter discrimination.
Other weight-related issues that may affect your quality of life include:
- Depression
- Disability
- Sexual problems
- Shame and guilt
- Social isolation
- Lower work achievement
Common Cause of Obesity or Weight Gain
Obesity has reached epidemic proportions within the USA. Over two-thirds of adults are overweight or obese, and one in three Americans is obese. The prevalence of obesity in children has increased markedly. Obesity has also been increasing rapidly throughout the planet, and therefore the incidence of obesity nearly doubled from 1991 to 1998. In 2015, nearly 40% of adults were obese within the U.S.
1.Intake too many Calories:
Foods that can increase the risk of weight gain include:
- fast foods.
- fried foods, such as french fries.
- fatty and processed meats.
- many dairy products.
- foods with added sugar, such as baked goods, ready-made breakfast cereals, and cookies.
- foods containing hidden sugars, such as ketchup and many other canned and packaged food items.
- sweetened juices, sodas, and alcoholic drinks.
- processed, high-carb foods, such as bread and bagels.
2. Living with a Sedentary Lifestyle:
Most of the people follow their parents and grandparents to live with a sedentary lifestyle.
Examples of sedentary habits include:
- working in an office rather than doing manual labor.
- playing games on a computer instead of doing physical activities outside.
- going to places by car instead of walking or cycling.
- Watching Movies restlessly by going to walk outside regularly.
3. Obesity Gene:
A study published in 2016 points to a link between this gene and:
- obesity
- behaviors that lead to obesity
- a higher food intake
- a preference for high-calorie foods
- an impaired ability to feel full, known as satiety
The hormone Ghrelin plays a crucial role in eating behavior. Ghrelin also affects the release of growth hormones and how the body accumulates fat, among other functions.
4. Not sleeping well:
When an individual doesn't sleep enough, their body produces ghrelin, a hormone that stimulates appetite. At an equivalent time, a scarcity of sleep also leads to lower production of leptin, a hormone that suppresses the appetite.
