1.Exercise and Fitness

Physical inactivity is a major risk factor for cardiovascular disease, and most Americans are not physically active enough to gain any health benefits. Swimming, cycling, jogging, skiing, aerobic dancing, walking or many other activities can help your heart.

Whether it's included in a structured exercise program or part of your daily routine, all physical activity adds up to a healthier heart.

According to the latest joint American Heart Association/American College of Sports Medicine guidelines on physical activity, all healthy adults ages 18-65 should be getting at least 30 minutes of moderate intensity activity five days of the week. However, there are additional guidelines for those 65 and older, or for those  50-64 with chronic conditions or physical functional limitations (e.g., arthritis) that affect movement ability or physical fitness.

The Benefits of Daily Physical Activity

  • Reduces the risk of heart disease by improving blood circulation throughout the body
  • Keeps weight under control
  • Improves blood cholesterol levels
  • Prevents and manages high blood pressure
  • Prevents bone loss
  • Boosts energy level
  • Helps manage stress
  • Releases tension
  • Improves the ability to fall asleep quickly and sleep well
  • Improves self-image
  • Counters anxiety and depression and increases enthusiasm and optimism
  • Increases muscle strength, increasing the ability to do other physical activities
  • Provides a way to share an activity with family and friends
  • Establishes good heart-healthy habits in children and counters the conditions (obesity, high blood pressure, poor cholesterol levels, poor lifestyle habits, etc.) that lead to heart attack and stroke later in life
  • In older people, helps delay or prevent chronic illnesses and diseases associated with aging and maintains quality of life and independence longer

2. Managing Your Weight

What Are the Keys to Healthy Weight Loss?  It's not rocket science, but successful weight loss requires a commitment to change your habits for the long haul. Take these three important steps toward a thinner and healthier you.

How Do You Maintain Weight Loss?  Once you've lost weight, the next step is to keep it off.  Learn what to expect and get tips for success.

What About Fad Diets?  Fad diets can be nutrition nightmares that shouldn't be sustained over time. Eating a balanced diet every day is the best way to maintain a healthy weight and prevent illness and disease.

Welcome to the No-Fad Diet  Forget the one-size-fits-all diets. Our plan gets personal and helps you create a strategy all your own to lose weight in a healthy way and keep it off for a lifetime.

Choose To Move

Choose To Move is a fun, free and flexible physical activity program for women. It lasts 12 weeks and helps participants gradually increase their physical activity levels to 30 minutes on most days of the week, a level shown to reduce the risk of heart disease and stroke.

Why Lose Weight?

The main reason to lose weight is for health, not appearance.

Nearly 112,000 deaths per year may be attributable to obesity.

The risk of death rises with increasing weight.

Even moderate weight excess (10 to 20 pounds for a person of average height) increases the risk of death, particularly among adults ages 30 to 64.

People who are obese (defined as having a body mass index [BMI] greater than 30) have a higher risk of excess death (they are more likely to die) from all causes, compared to people at a healthy weight.

  • Obesity is now recognized as a major risk factor for coronary heart disease, which can lead to heart attack. Some reasons for this higher risk are known, but others are not. For example:
  • The incidence of heart disease is higher in persons who are overweight or obese (BMI greater than 25).
  • High blood pressure is more common in adults who are obese than in those who are at a healthy weight.
  • Obesity is associated with elevated triglycerides (blood fat) and decreased HDL cholesterol ("good") cholesterol.
  • Even when there are no adverse effects on the known risk factors, obesity by itself increases the risk of heart disease.

The consequences of weight gain are serious for other health issues as well.

  • A weight gain of 11 to 18 pounds increases a person's risk of developing type 2 diabetes to twice that of people who have not gained weight.
  • Over 80 percent of people with diabetes are overweight or obese.
  • Overweight and obesity are associated with an increased risk for some types of cancer including endometrial (cancer of the lining of the uterus), colon, gall bladder, prostate, kidney and postmenopausal breast cancer.
  • Women gaining more than 20 pounds from age 18 to midlife double their risk of postmenopausal breast cancer, compared to women whose weight remains stable.
  • Sleep apnea (interrupted breathing while sleeping) is more common in obese persons.
  • Obesity is associated with a higher prevalence of asthma.
  • For every 2-pound increase in weight, the risk of developing arthritis increases by 9 to 13 percent.
  • Symptoms of arthritis can improve with weight loss.

3. Obesity in children

Childhood obesity is one of our nation's leading health threats. Today, 11 million kids are overweight, and an additional 13 million are at risk for being overweight. As a result more and more kids are developing conditions and diseases that we would normally associate with adults-like high blood pressure, elevated cholesterol, and type-2 diabetes.

To combat this epidemic, the American Heart Association and the William J. Clinton Foundation, along with California Gov. Arnold Schwarzenegger (R-CA), have joined together to form the Alliance for a Healthier Generation. The Alliance's goal is to stop the nationwide increase in childhood obesity by 2010 by taking bold, innovative steps to help all children live longer and healthier lives. The Alliance will positively affect the places that can make a difference to a child's health: homes, schools, restaurants, doctors' offices, and the community.

The Alliance for a Healthier Generation is uniquely positioned to create change. It combines the American Heart Association's extensive reach into communities across the country, its credible science expertise, strong presence in schools, and nationwide network of volunteers and supporters, with the entrepreneurial approach, focus and innovation of the William J. Clinton Foundation.

Since the Alliance formed in May 2005, it has laid the groundwork for major change in schools through the Healthy Schools Program (launched with support from the Robert Wood Johnson Foundation), brokered a landmark agreement with the beverage and snack food industries to offer healthier food and drink options in schools, and partnered with Nickelodeon to create the Let's Just Play Go Healthy Challenge, a television show, web and community-level campaign that empowers kids to take charge of their own health.
