And women younger than 40 appear to be particularly vulnerable to the risks of a sedentary lifestyle.
Taking a more global view, the prestigious British Medical Journal BMJ looks at various attempts to tackle obesity and notes that obesity is caused by a complex and multitude of inter-related causesfuelled by economic and psychosocial factors as well as increased availability of energy dense food and reduced physical activity.
The authors broke down the causes into the following areas: Food systems causes of obesity The main problem has been the increased availability of high energy food, because of: Liberalized international food markets Food subsidies that have arguably distorted the food supply in favour of less healthy foodstuffs Transnational food companies [that] have flooded the global market with cheap to produce, energy dense, nutrient empty foods Supermarkets and food service chains [that are] encouraging bulk purchases, convenience foods, and supersized portions Healthy eating often being more expensive than less healthy options, despite global food prices having dropped on average.
Marketing, especially food advertising through television [which] aims to persuade individuals—particularly children—that they desire foods high in saturated fats, sugars, and salt.

His wish that the TED Prize speech asks him to share was to help to create a strong, sustainable movement to educate every child about food, inspire families to cook again and empower people everywhere to fight obesity. He explained this in his video: Teach every child about foodTED, February Given the complex, inter-related causes of obesity, addressing it also requires a multi-pronged approach: Dealing with inequalities in obesity requires a different policy agenda from the one currently being promoted.
Action is needed that is grounded in principles of health equity. Action must tackle the inequities in this system, aiming to ensure an equitable distribution of ample and nutritious global and national food supplies; built environments that lend themselves to easy access and uptake of healthier options by all; and living and working conditions that produce more equal material and psychosocial resources between and within social groups.
This will require action at global, national, and local levels. While important, on its own, they feel it is not sufficient; there is limited evidence for sustainability [of this direct approach] and transferability to other settings, for example.
Furthermore, the recent UK Foresight Report makes clear the complexity of drivers that produce obesity; it highlights that most are societal issues and therefore require societal responses. The therefore describes some examples of initiatives at these various levels: Addressing obesity at the global level This involves international institutions, agreements, trade and other policies.
A joint program of the United Nations Food and Agriculture Organization and the World Health Organization, the experience of the Codex Alimentarius Commission highlights the challenges at international level.
The Commission was set up to help governments protect the health of consumers and ensure fair trade practices in the food trade. But challenges and obstacles persist. For example, industry representatives hugely outnumber representatives from public interest groups, resulting in an imbalance between the goals of trade and consumer protection.
In addition, Ensuring that global food marketing does not target vulnerable societies the BMJ feels there needs to be binding international codes of practice related to production and marketing of healthy food, supported at the national level by policy and regulation.
Emphasis added For example, regulating television advertising of foods high in fat or sugar to children is a highly cost effective upstream intervention.
Addressing obesity at the national level National policies typically aimed at healthier food production include targeted and appropriate domestic subsidies. For example, Norway successfully reversed the population shift towards high fat, energy dense diets by using a combination of food subsidies, price manipulation, retail regulations, clear nutrition labelling, and public education focused on individuals.
Mauritius relatively successful program includes price policy, agricultural policy, and widespread educational activity in various settings.Obesity and lack of exercise cause a variety of problems in both the adult and child populations of the United States.
