Worldwide obesity has nearly tripled since 1975. Overweight and obesity are defined as an excessive fat accumulation that may have a negative health impact on the body. The majority of fat stored on the human body is present under the skin. It is the energy imbalance between calories consumed and calories expended.
The most common way to determine if a person is overweight or obese is to calculate the BMI – (Body Mass Index). It is a statistical measurement derived from your height and weight. It helps to measure the percentage of body fat. For eg: If a person’s body weight is 20% higher than it should be and BMI is 30 or over they are considered to be obese. If the Body Mass Index (BMI) is between 25 and 29.9 the person is considered to be overweight.
Some of the Causes of Overweight and obesity
Food intake and Lifestyle
Overeating is the excess food intake which comes in relation to the energy that an organism expends leading to weight gaining and often obesity. High consumption of calories, fats, sweetened drinks, sweets, fast food etc increases the body fat. A major increase in physical inactivity leads to sedentary nature. With the arrival of televisions, computers, washing machines, dishwashers and other modern convenience devices people have become inactive. Changing modes of transportation has become easier and people have completely stopped walking.
Health conditions and Medications
The underactive Thyroid, Cushing syndrome, Insulin, Leptin, and Polycystic ovary syndrome are the hormonal problems that cause overweight and obesity.
There are many drugs which can cause weight gain as a side effect. These drugs don’t cause a willpower deficiency but they alter the function of the body and brain by making it store fat instead of burning it.
It contributes towards weight gain. Scientists believe that genes may increase a person’s likelihood of becoming obese. However, the outside factors such as an abundant food supply or little physical activity are the main reason to put on excess weight.
Poor sleep and Emotional factors
Some people eat more in comparison with a normal person. It usually happens when they are bored, angry, upset, or stressed.
Studies also have found that the fewer people sleep, the chances are more to gain weight or obese. The hormones that are released during sleep controls the appetite and the body’s use of energy.
The leading causes of death are due to chronic diseases such as heart disease, stroke, cancer and diabetes, conditions which are all strongly related to diet. There is a high risk if the person is overweight and obese which may also lead to many health problems such as
- type 2 diabetes
- high blood pressure
- certain types of cancer
- sleep apnea
- shortness of breath
- heart disease and strokes
- varicose veins
- fatty liver disease
- kidney disease
- pregnancy problems, such as high blood sugar during pregnancy, high blood pressure, and increased risk for cesarean delivery
- Eat five to six servings of fruits and vegetables daily
- Choose whole-grain foods
- Weigh yourself regularly
- Avoid foods that are high in “energy density”
- Workout for at least 30 minutes a day to burn calories (Regular exercise)
Healthy behavior includes a healthy diet pattern and regular physical activity. It can be calculated as the energy balance of the number of calories consumed from foods and beverages with the number of calories the body uses for activity. This plays a role in preventing excess weight gain. Regular exercise and correct diet can decrease the overall body fat, this will also help reduce fat in the most abundant parts of the body.
