Why do people become obese?
1) Consuming too many calories.
These days people are eating much more food than in previous generations. 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).
In the USA, the consumption of calories increased from 1,542 per day for women in 1971 to 1,877 per day in 2004. The figures for men were 2,450 in 1971 and 2,618 in 2004. Most people would expect this increase in calories to consist of fat - not so! Most of the increased food consumption has consisted of carbohydrates (sugars). Increased consumption of sweetened drinks has contributed significantly to the raised carbohydrate intake of most young American adults over the last three decades. The consumption of fast-foods has tripled over the same period.
2) Leading a sedentary lifestyle
With the arrival of televisions, computers, video games, remote controls, washing machines, dish washers and other modern convenience devices, people are commonly are leading a much more sedentary lifestyle compared to their parents and grandparents.

Research has suggested that if you do not sleep enough your risk of becoming obese doubles. Research was 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.
