"Every American is looking for (the National Institutes of Health) to come up with that pill. It's not going to happen," said Tommy Thompson, secretary of Health and Human Services.
"You want to look better? You want to feel better? To do that, lower your caloric intake, lower the fats and carbs, eat more whole grains. And you exercise."
The last guidelines were released in 2000 but had no advise on exercise.
In the new advice, exercise should be moderately vigorous, but no specific activity is recommended.
"Engage in approximately 60 minutes of moderate- to vigorous-intensity activity on most days of the week," say the fat-fearing feds.
Over at the National Center for Chronic Disease Prevention and Health Promotion, there's specific advise on which exercises are best to incorporate into a person's daily routine:
"There are 1440 minutes every day. Schedule 30 of them for physical activity. Walk, cycle, jog, skate, etc., to work, school, the store, or place of worship."
