Why do people become obese?
People become obese for several reasons,
including:
1.
Consuming too many calories.
People are eating much more than they used to. This used to be the case just in developed nations - however, the trend has spread worldwide. Despite billions of dollars being spent on public awareness campaigns that attempt to encourage people to eat healthily, the majority of us continue to overeat. In 1980 14% of the adult population of the USA was obese; by 2000 the figure reached 31% (The Obesity Society).
Various other factors also may have contributed to America's increased calorie and carbohydrate intake:

Various other factors also may have contributed to America's increased calorie and carbohydrate intake:
§ In 1984 the
Reagan administration freed up advertising on sweets and fast foods for
children - regulations had previously set limits.
§ Agricultural
policies in most of the developed world have led to much cheaper foods.
§ The US Farm
Bill meant that the source of processed foods came from subsidized wheat, corn
and rice. Corn, wheat and rice became much cheaper than fruit and vegetables.
2.
Leading a sedentary lifestyle.
With the arrival of televisions, computers, video games, remote controls, washing machines, dish washers and other modern convenience devices, the majority of people are leading a much more sedentary lifestyle compared to their parents and grandparents. Some decades ago shopping consisted of walking down the road to the high street where one could find the grocers, bakers, banks, etc. As large out-of-town supermarkets and shopping malls started to appear, people moved from using their feet to driving their cars to get their provisions. In some countries, such as the USA, dependence on the car has become so strong that many people will drive even if their destination is only half-a-mile away.

3.
Not sleeping enough.
If you do not sleep enough your risk of becoming obese doubles, according to research carried out at Warwick Medical School at the University of Warwick. The risk applies to both adults and children. Professor Francesco Cappuccio and team reviewed evidence in over 28,000 children and 15,000 adults. Their evidence clearly showed that sleep deprivation significantly increased obesity risk in both groups.

Endocrine disruptors, such as some foods that interfere
with lipid metabolism.
A team from the University of Barcelona (UB) led by Dr Juan Carlos Laguna published a study in the journal Hepatology that provides clues to the molecular mechanism through which fructose (a type of sugar) in beverages may alter lipid energy metabolism and cause fatty liver and metabolic syndrome.

5.
Lower rates of smoking (smoking suppresses appetite).
According to the National Institutes of Health (NIH) "Not everyone gains weight when they stop smoking. Among people who do, the average weight gain is between 6 and 8 pounds. Roughly 10 percent of people who stop smoking gain a large amount of weight - 30 pounds or more."

6.
Medications that make patients put on weight.
According to an article in Annals of Pharmacotherapy, some medications cause weight gain. "Clinically significant weight gain is associated with some commonly prescribed medicines. There is wide interindividual variation in response and variation of the degree of weight gain within drug classes. Where possible, alternative therapy should be selected, especially for individuals predisposed to overweight and obesity."
