DGAC 2015 Recommendations for Action
The official position seems to be that:
If you are already healthy, the recommended low-fat and high-carbohydrate diet is the best diet.
On any diet, you need to control the number of calories you consume, so that they are equal to the number of calories you burn.
If your weight is still a problem, you need to exercise more.
Actions for Individuals and Households
It will take concerted, bold action ... to achieve and maintain healthy dietary patterns, and the levels of physical activity needed to promote a healthy U.S. population.
This will entail dramatic paradigm shifts ... to achieve a population-wide "culture of health" ... both at home and away from home.
Health care professionals
Health care and public health professionals would embrace a new leadership role in prevention, convey the importance of lifestyle behavior change to their patients/clients.
Know your lifestyle-related health risk profile, make personal goals and commitments, and take action to promote personal and household/family health. Monitor your health risks and to personalize your preventive lifestyle behavior plan of action.
For most people, this will mean:
Improving food and menu choices
Including more vegetables (without added salt or fat), fruits (without added sugars), whole grains, seafood, nuts, legumes, low/non-fat dairy or dairy alternatives (without added sugars).
Reducing Red Meat Consumption
Reducing consumption of red and processed meat, refined grains, added sugars, sodium, and saturated fat; substituting saturated fats with polyunsaturated alternatives; and replacing solid animal fats with non-tropical vegetable oils and nuts.
Take responsibility for your results
Initiate positive personal lifestyle changes to improve dietary and physical activity behaviors, including goal setting and self-monitoring.
Achieve and maintain a healthy weight.
Recognizing that many evidence-based options can facilitate weight loss and weight loss maintenance. As appropriate, work with qualified nutrition professionals and health providers to create a personalized plan of action for obesity prevention.
For weight control, at least one hour a day of moderate to vigorous intensity physical activity may be required. Adults should limit sedentary activity and replace it with aerobic and strengthening exercises.
Engage in at least 2.5 hours a week of moderate-intensity aerobic physical activity, such as brisk walking, or 1.25 hours a week of vigorous-intensity aerobic physical activity.
Get enough sleep!
This comment wasn't quantified, but clearly too many of us try to get by on too little sleep.
