Does vegetable oil causes obesity:
Obesity is a systemic problem, not a result of widespread loss of personal willpower to cut calories or a new unwillingness to exercise. If weight loss were as easy as deciding to ignore hunger signals and taking the stairs instead of the elevator, we would not have an obesity rate of 42.4% in the U.S., with the rest of the world quickly catching up. And we would not have an increasing percentage of American children who are overweight or obese, having grown from 36% to 46% of American kids in the last two years alone.
