Obesity has become a global epidemic affecting millions of people across the world. According to the World Health Organization, over 650 million adults and 340 million children and adolescents were estimated to be obese in 2016.
While the most commonly known factors contributing to obesity include a poor diet and physical inactivity, there are several other hidden factors that also play a significant role in weight gain.
1. Genetics
Research shows that genetics play a role in determining a person’s likelihood of becoming obese. Some people are genetically predisposed to gain weight more easily than others.
A study conducted by the National Institutes of Health found that genetics account for approximately 40 to 70 percent of a person’s risk of obesity.
2. Sleep Deprivation
Lack of sleep is another hidden factor contributing to obesity. When we are sleep-deprived, our bodies produce more of the hunger hormone ghrelin and less of the hormone leptin, making us more likely to overeat and gain weight.
A study conducted by the University of Chicago found that people who sleep less than five hours a night are more likely to be obese than those who get seven to eight hours of sleep.
3. Medications
Several medications can contribute to weight gain, including antidepressants, antipsychotics, and corticosteroids. These drugs can affect the metabolism and cause an increase in appetite, leading to weight gain.
If you are taking any medications that you suspect may be contributing to weight gain, it’s important to speak to your healthcare provider to determine if there are other options available.
4. Stress
Chronic stress can cause a release of the hormone cortisol, which can lead to an increase in appetite and weight gain. People who are stressed are also more likely to engage in emotional eating, where food is used to cope with negative emotions.
Finding healthy ways to manage stress, such as exercise, meditation, or therapy, can help prevent weight gain.
5. Environmental Factors
Our environment plays a significant role in our ability to maintain a healthy weight.
Factors such as lack of access to healthy foods, food deserts, and living in neighborhoods without sidewalks or safe places to exercise can make it more difficult to maintain a healthy lifestyle. Additionally, exposure to endocrine-disrupting chemicals found in many household products and processed foods can contribute to weight gain.
6. Age
As we age, our metabolism naturally slows down, making it easier to gain weight. Additionally, as we age, we tend to become less active, leading to a loss of muscle mass and a decrease in metabolism.
Hormonal changes associated with menopause can also lead to weight gain in women.
7. Medical Conditions
Several medical conditions can contribute to weight gain, including hypothyroidism, polycystic ovary syndrome (PCOS), and Cushing’s syndrome.
These conditions can affect the metabolism and cause weight gain even when a person is not eating more calories than they are burning.
8. Pregnancy
Weight gain during pregnancy is normal and necessary. However, if a woman gains too much weight during pregnancy, it can be difficult to lose after the baby is born.
Additionally, if a woman has multiple pregnancies, she may be more likely to gain weight over time.
9. Social Factors
Our social environment can also contribute to weight gain. People who have social support and accountability are more likely to maintain a healthy weight.
On the other hand, people who live in environments where unhealthy eating and sedentary lifestyles are the norm are more likely to be overweight or obese.
10. Disability
People with disabilities are more likely to be obese than people without disabilities. This may be due to a lack of access to physical activity, as well as limited access to healthy foods.
In conclusion, while a poor diet and physical inactivity are the most commonly known factors contributing to obesity, there are several other hidden factors that also play a significant role in weight gain.
By addressing these hidden factors, we can help prevent and treat obesity and improve overall health.
