What is obesity? And what causes it?
Obesity is a challenging disease that involves excessive body fat. It's a dangerous condition that can have a serious effect on your health. It raises the risk of various illnesses and health issues like heart disease, type 2 diabetes, and high blood pressure, depression, arthritis, respiratory disorders, and gastrointestinal diseases.
A person's body mass index (BMI) is the biggest indication or symptom of obesity. A lean individual generally has an 18.5 or lower BMI whereas an individual is regarded as overweight if his or her BMI of 25 or above. The greater the BMI, the greater the risk to health.
Causes of obesity
1) Consuming too many calories
If you consume more calories than what you use as energy, the extra calories will be stored as fat in your body. This can lead to you becoming overweight or obesity. In addition, a diet that's high in calories can result in weight gain, particularly processed foods that have elevated levels of fats and sugars.
2) An inactive lifestyle
If an individual consumes more calories than the energy they use, the excess calories will be stored as fat by their bodies. The less an individual moves around, the fewer calories he burns. Physical activity also impacts how the hormones of a person's function and the hormones affect how food is processed by the body. Several studies have shown that physical activity can help stabilize insulin concentrations and that excessive levels of insulin can result in weight gain.
3) Not getting enough sleep
Research has suggested that the lack of sleep increases the danger of weight gain and obesity. It was found that in both adults and kids, lack of sleep considerably increased the risk of obesity. This happens because, when an individual does not sleep enough, their body generates ghrelin, an appetite-stimulating hormone. Simultaneously, the absence of sleep also leads to reduced leptin production, a hormone that suppresses appetite.
Medications including antidepressants, anti-seizure medications, diabetes medications, steroids, and beta-blockers can lead to weight gain this is because they decreasing the number of calories burned and may increasing your appetite. That is why it is advisable to consult with your doctor before taking any new medications.
The amount of body fat you store and where that fat is distributed can be affected by your genes. Studies have shown If one or both parents are obese, an individual is more likely to develop obesity. Genetics can also play a part in how your body transforms food into energy effectively and how your body burns calories during exercise.
