have you heard of fast food and perhaps slow, but how about hard foods? A new study suggests that the most difficult food to eat, we eat less and less books that we pack on. The work was inspired by the growing obesity epidemic; Statistics from the World Health Organization suggest that obesity has almost doubled worldwide since 1980, a trend many blame on a wide range of processed foods, including high-calorie energy drinks, and a trend to eat fast foods rather than taking the time to cook and enjoy a healthy meal. So a team of researchers wondered whether changing the texture of foods could make a difference. On two consecutive days, the scientists fed 50 healthy 20-somethings a lunch of burgers and a side of rice with vegetables. On one of the two days, each participant was served a small sweet bread and boiled vegetables, while on the other, they ate hard bread and raw vegetables. Each day concluded with a dinner of noodles, chicken and vegetables 5 hours later. When they ate the meal more chewy, participants consumed about 0 fewer calories on average, a drop of about 13% compared to the softer lunch. In addition, they ate about the same amount for dinner two days, which means they did not compensate with a larger dinner after a smaller, rubbery breakfast. Writing this week PLOS ONE , the authors say their findings suggest that slight changes in the texture of foods may lead people to take in fewer calories in the long run, may help them lose weight. Eat less, it is, could be as simple as eating hard.
