Obesity is a condition that is associated with having an excess amount of body fat, defined by genetic, behavioral and environmental factors. An adult with a BMI of 30 or greater is considered to have obesity.

As per the best nutritionist in Delhi, there are many causes that directly or indirectly contribute to obesity. Behavioral, Environmental and genetic factor are the major causes. Out of all the very important aspects that you can control obesity are food intake and physical activity. In this article, we discuss few most important causes of Obesity:

More of this food intake is lacking in fiber. Excessive consumption of these foods tend to increase your fat mass, elevate blood glucose level very quickly, which causes your pancreas to produce more insulin to prevent your blood glucose from getting too high, which will lead to deposition of fat in the cells, which will subsequently leads to lower your metabolism. When we talk about the quantity of food, it meant the amount of food and the amount of nutrients as well. Usually more food we take, the more calorie we intake which again leads to deposition of fat in the body leading to obesity. It means the increase in food intake than your body burns it.
  3. Sedentary lifestyle and lack of exercise:

  4. The person who sits more than 5 hours at workplace is considered to be sedentary life styled person. Few of the things like people who watch TV and sleep a lot, Desk job, and home makers.
