There's no way around it. But getting older does not have to mean getting weaker or sick. Eating a balanced diet and exercising moderately may be the closest thing to the proverbial fountain of youth by strengthening the body and helping fight disease, according to Radford University professor BB Strum. It's not old age or aging that has caused this process, it's inactivity. For older people, weight-bearing activities such as weight training and walking help to prevent osteoporosis and also increase the number of HDLs, the good cholesterol.
Appropriate exercise done correctly is the best health insurance.
You can determine your BMI with the help of your doctor, or there are many sources on the Internet that can help. Eating a balanced diet and staying within your calorie limit in addition to participating in moderate aerobic and weight resistance training most days of the week can help ward off stress and disease as well as provide more energy. Marcella Griggs, nursing professor at RU, agrees, and says that a lack of proper nutrition or exercise can lead to obesity which has a rippling effect and can contribute to the development of chronic illnesses, such as heart disease, high blood pressure and arthritis. Those illnesses then lead to other health problems such as diabetes or joint problems requiring surgery. It's not all cause and effect.
