How Weight Loss is Linked to Future Health for Older Adults

Journal of the American Geriatrics Society Research Summary

Studies describing the effects of weight loss on health rarely consider age. However, weight loss during middle age likely has different effects on your health than does weight loss when you’re 65-years-old or older—especially when you’re older than 85.

Although some studies have found that weight loss in older adults is generally linked to an increase in illness and death, researchers say that these studies were either too short or were based on information that may have been interpreted incorrectly.

However, one study about fractures and osteoporosis (a medical condition in which bones become thin, lose density, and become increasingly fragile) looked specifically at health and weight for women who were over age 65. Reviewing more than 20 years’ worth of data for study participants, the team of researchers responsible for this study had the chance to examine links between long-term weight gain/loss and health. Their findings were published in the Journal of the American Geriatrics Society. Continue reading

For Older Adults with Diabetes, Losing Weight through Diet and Exercise Can Improve Blood Circulation in the Brain

JAGS graphicJournal of the American Geriatrics Society Research Summary

Type 2 diabetes affects blood circulation. The disease stiffens blood vessels and reduces the amount of oxygen that circulates throughout your body. This includes your brain. When blood flow in the brain is impaired, it can affect the way we think and make decisions.

People who have type 2 diabetes are often overweight or obese. These are conditions that may also be linked to cognitive problems (problems with thinking abilities). Lowering calorie intake and increasing physical activity are known to reduce the negative effects of type 2 diabetes on the body. However, the effects of these interventions on cognition and the brain are not clear.

Recently, researchers examined information from a 10-year-long study called Action for Health in Diabetes (Look AHEAD). In this study, participants learned how to adopt healthy, long-term behavior changes. In their new study, the researchers focused on whether participants with type 2 diabetes who lowered calories in their diet and increased physical activity had better blood flow to the brain. The researchers published their findings in the Journal of the American Geriatrics Society. Continue reading
