It can be hard to know where to start with so many diets, surgeries, and
workouts vying for popular attention.
That's why a team of health experts recently came up with practical
recommendations for weight loss to fight heart disease.
Their findings form a statement by the American Heart Association Council on
Nutrition, Physical Activity, and Metabolism. The statement, which appears in
the journal Circulation, was endorsed by the American College of Cardiology
Foundation.
The experts, who included American Heart Association President-Elect Robert
Eckel, MD, began by reviewing the hazards of obesity.
Besides heart disease, obesity is linked to health problems including increased
risk for type 2 diabetes, high blood pressure, and insulin resistance.
However, many of those conditions can be improved or avoided through weight loss
and exercise.
"The data demonstrate that weight loss and physical activity can prevent and
treat obesity-related coronary heart disease risk factors and should be
considered a primary therapy for obese patients with cardiovascular disease,"
write the experts.
Practical Tips
It all comes down to burning more calories than you consume, creating an "energy
deficit." Here are some tips on how to do that from the experts' statement:
-
Obese people trying to lose weight should aim for an energy deficit of 500 to
1,000 calories per day. In other words, try to consume 500 to 1,000 fewer
calories than you need.
-
Both diet and exercise are important, although it may be easier to create an
energy deficit by restricting calories than through exercise alone.
-
Eat fruits, vegetables, grains, low- or nonfat dairy products, fish, legumes,
poultry, and lean meats.
-
Limit foods high in saturated fat, trans-fatty acids, and cholesterol.
-
Get at least 30 minutes of moderate-intensity physical activity most days of
the week.
-
Keep diaries of food and exercise to build awareness of habits.
-
Set specific short-term goals.
-
Identify "triggers" associated with poor eating/exercise habits, and come up
with new responses.
-
Learn to handle stress without eating poorly.
-
Enlist support of family and friends.
-
Develop skills for staying healthy in challenging situations, such as travel,
celebrations, and bad moods.
Weight loss surgery may be an option for obese people with a body mass index
(BMI) of 35 to 39.9 plus at least one severe obesity-related medical
complication, say the researchers, citing previous guidelines from the National
Institutes of Health.
Prescription weight loss drugs might be considered for people with a BMI of 30
or more, or those with a BMI of 27-29.9 who also have an obesity-related
medical condition, say the researchers.
Of course, anyone seeking to lose weight or facing heart disease should enlist
the help of their health-care provider.
Besides teaching patients these guidelines, doctors could also make their
offices more comfortable by providing armless chairs, large gowns and
blood-pressure cuffs, and a scale in a private area of the office that can
weigh people over 300 pounds, say the researchers.
