According to the British Government think tanks, it is not only over eating and lack of exercises that leads to the current obesity problem, but it is modern life that leads to this situation. They found that technological revolution of the 20th century has led to weight gain becoming unavoidable for the majority of the population (From Yahoo News).
"Stocking up on food was key to survival in prehistoric times, but now with energy dense, cheap foods, labor-saving devices, motorized transport and sedentary work, obesity is rapidly becoming a consequence of modern life," said Sir David King, the British government's chief scientific adviser and head of the Foresight program.
They predicted that it would take at least thirty years to reverse this epidemic like growing obesity problem. Government has so far designed policies to encourage people especially children to adopt healthier lifestyles, eating less fast food items and doing more exercise.
But according to Sir David, everyone has to make change in his or her attitudes to solve the obesity problem. Researchers said that there is no magic bullet to solve this problem and also there is no appetite-suppressing drug that can solve this problem, as the obesity problem is systemic.
To solve obesity problem, we have to make big changes in society with increase in our daily routine activities. According to the researchers, if we continue with the same obesity growth, approx 60 % of men, 50 % of women and 25 % of children in the country will be obese by 2050.
Commenting on the report, British public health minister Dawn Primarolo said: "We have made progress with improved physical activity levels at school, healthier school food for children, clearer food labeling and tougher restrictions on advertising foods high in fat and sugar to children -- but we know that we need to go further and faster."
