Causes of Obesity

The onset of obesity can be due to a variety of reasons and with our fast-evolving
urban lifestyles, we are seeing these factors play out more than ever before.


  • Frequent consumption of fast foods which are high in fat and sugar
  • Drinking heavily sweetened beverages or soft drinks
  • Regular consumption of alcohol

Erratic Eating

  • Irregular meal timings or eating inconsistently may affect our internal body clock, making one prone to the epidemic of obesity
  • It can also slow down metabolism leading to weight gain
  • Starving and then eating large portions at once can also increase calorie intake, further causing weight gain

Lack of Exercise

  • Technological distractions have bred physical inactivity. As a result the extra calories in the body are stored as fat which should have ideally been burnt
  • The increasing workloads of an urban populace have made sure that exercise has been pushed out of peoples schedules thereby resulting in unwanted weight gain


  • Work related stress can give rise to poor eating habits and a loss of interest in exercise
  • Smoking/alcohol use increases risk of weight gain


  • Family history of obesity can also prompt weight gain

Endocrine Factors

Obesity is caused due to the onset of various medical conditions:

  • Hypothyroidism – This is a condition where the thyroid gland, located in the neck produces too little of the thyroid hormone. The thyroid hormone regulates our metabolism. So too little of the hormone slows the metabolism and often causes weight gain.
  • Cushing’s Syndrome – This condition results when the adrenal glands (located on the top of each kidney) produce an excess amount of a steroid hormone called cortisol. This leads to a build-up of fat in characteristic sites such as the face, upper back, and abdomen.
