NIH study of rare disorder shows that low levels of brain chemical may lead to obesity. A brain chemical that plays a role in long term memory also appears to be involved in regulating how much people eat and their likelihood of becoming obese, according to a National Institutes of Health study of a rare genetic condition.
Overweight and obesity have been associated with increased risk of developing such conditions as high blood pressure, Type 2 diabetes and coronary artery disease.
The best exercise for your bones is the weight-bearing kind, which forces you to work against gravity. Some examples of weight-bearing exercises include weight training, walking, hiking, jogging, climbing stairs, tennis, and dancing.
If you have health problems – such as heart trouble, high blood pressure, diabetes, or obesity – or if you are age 40 or older, check with your doctor before you begin a regular exercise program.
In order to understand osteoporosis, it is important to learn about bone. Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework.
Throughout life, bone is constantly renewed through a two-part process called remodeling. This process consists of resorption and formation. During resorption, old bone tissue is broken down and removed by special cells called osteoclasts.
Think of bone as a bank account where you "deposit" and "withdraw" bone tissue. During childhood and the teenage years, new bone is added to the skeleton faster than old bone is removed. As a result, bones become larger, heavier, and denser.
If you have heart disease, it doesn’t necessarily mean that you should avoid physical activity. In fact, most people with heart disease and those who are at high risk of developing heart disease can benefit from regular light to moderate exercise.
Although the Guidelines focus on the health benefits of physical activity, these benefits are not the only reason why people are active. Physical activity gives people a chance to have fun, be with friends and family, enjoy the outdoors, improve their personal appearance, and improve their fitness so that they can participate in more intensive physical activity or sporting events.
Classification of Total Weekly Amounts of Aerobic Physical Activity Into Four Categories. Inactive, low activity, medium activity, and high activity.
Setting the right goals is an important first step. Most people trying to lose weight focus on just that one goal: weight loss. However, the most productive areas to focus on are the dietary and exercise changes that will lead to that long-term weight change.
To get all of the benefits of physical activity, try all four types of exercise – 1) endurance, 2) strength, 3) balance, and 4) flexibility.
Almost anyone, at any age, can do some type of physical activity. You can still exercise even if you have a health condition like heart disease or diabetes. In fact, physical activity may help. For most older adults, brisk walking, riding a bike, swimming, weight lifting, and gardening are safe, especially if you build up slowly.
Here are some things you can do to make sure you are exercising safely: Start slowly, especially if you haven’t been active for a long time. Little by little build up your activities and how hard you work at them.
During moderate-intensity activities you should notice an increase in your heart rate, but you should still be able to talk comfortably. An example of a moderate-intensity activity is walking on a level surface at a brisk pace (about 3 to 4 miles per hour).
If you want to lose a substantial (more than 5 percent of body weight) amount of weight, you need a high amount of physical activity unless you also lower calorie intake.
The benefits of exercise are well-documented. Unfortunately, that's not always the case with advertising claims for exercise equipment.
The advertised results may be based on more than just the use of the machine; they also may be based on restricting calories. The fine print may explain this. Even if it doesn't, keep in mind that diet and exercise together are much more effective for achieving a healthy, toned body than either tactic is alone.
To help you choose the best equipment for your needs, check out consumer and fitness magazines that rate exercise equipment. Then test various pieces of equipment at a local gym, recreation center or retailer to find the machine or device that feels comfortable to you.

If you can't set aside one block of time, do short activities throughout the day, such as three 10-minute walks. Create opportunities for activity. Try parking your car farther away from where you are headed. If you ride the bus or train, get off one or two stops early and walk.
