Causes of Obesity

Developing awareness of the causes of excessive weight gain may encourage people to be more attentive to their personal wellbeing.

Here are some of the major causes of obesity:

  • eating too much fat giving excess energy stored in the body
  • too much sugar, starch or other carbohydrates which are also important energy sources convertible into fats
  • too much of pre-processed products (no-cook or easy-to-cook) that often have more fat or sugar, for preservation (sweet beverages, pop, cakes, ice-cream, fast food and pre-packed snacks)
  • eating too much food altogether!
  • irregular eating habits, like eating much at one time (binge), little at another time, long span in-between some meals, consuming food with high doses of sugar at some times while no sugar at other times – producing an uncontrollable metabolism making you deposit more fats in your body
  • consuming too many high-calorie alcoholic drinks
  • lack of vitamins and minerals, and a generally unhealthy diet decreasing the body’ capacity to burn extra amounts of fats and sugar
  • inactive ‘sitting’ lifestyle wherein the body burns little fat and sugar, and
  • boredom in daily routine life resulting to excessive eating as a way of getting entertainment

Compared with a healthy weight man, an obese man is:

  • five times more likely to develop type 2 diabetes
  • three times more likely to develop cancer of the colon
  • more than two and a half times more likely to develop high blood pressure – a major risk factor for stroke and heart disease

An obese woman, compared with a healthy weight woman, is:

  • almost 13 times more likely to develop type 2 diabetes
  • more than four times more likely to develop high blood pressure
  • more than three times more likely to have a heart attack

A BMI of 30 to 35 has been found to reduce life expectancy by an average of three years, while a BMI of over 40 reduced longevity by eight to 10 years, which is equivalent to a lifetime of smoking.
