The world nowadays, has more presence of obese if you compare to hungry people. A study conducted by Prof. Barry Popkin of the University of North Carolina told the annual conference of the International Association of Agricultural Economist as quotes"The reality is that globally far more obesity than under nutrition exists". It is estimated that the world population of 6.5 billion are overweight and more than a billion is overweight.
The rest of the 800 million are undernourished. Thus, the trends of hunger decline while the trends of obesity are rapidly spreading around the world. These signify the norm of malnutrition is overwhelming. Being obese does not signify healthy lifestyles and negates many factors resulting in many diseases related to being obese. The risk of acquiring obesity is typically greater tracing from shifting from the rich to the poor and not only concentrated in urban and rural areas all around the world.
A primary example is China, putting all the typical changes with a major shift in diet from cereals to animal's products and accompany by increased intake of vegetable oils. Increased factors for obesity were the high incidence of decline in physical work, being a couch potato and the used of motorized transport even in short distances of travel instead of walking. A tactic to lessen obesity have been suggested such as the manipulation of food prices to changes the people diet and influences them to buy healthier food.
If the costs of subsidizing fruit and vegetable production lower, this would incline people to consume it more. Further study conducted by University of Minnesota's Prof. Benjamin Senauer used a comparative study between Japan and the USA in terms of cost of food and transport influences in high incidence of obesity trends differences. Japan has the lower incidence of obesity compare to American. Many factors such as exercises and economic influences were some attributes.
The lifestyles of Japan and the USA also differs when the typical Japanese cities focused more on public transport and walking while the typical American commutes daily, does little walking and even in short distances drive to supermarket using their vehicles instead of walking. With the presence of modern technology eliminated the need to exercise and most calories and fat cost decreased over time. The conscious effort to lose weight requires serious efforts without paying for gym or sport membership. Finally, obesity and weight bring significant risk of premature death and many complications from chronic diseases due to sedentary lifestyles.
