Watch nowEven if you work out, spending most of your day sitting may still adversely affect your health in ways that don't become apparent until later in life. A recent study found that 35-year-olds who engaged in 30 minutes of vigorous exercise each day had cholesterol levels comparable to those of sedentary 30-year-olds, suggesting that vigorous exercise can offset up to five years of age-related decline in heart health. Researchers analyzed data from adults aged 28 to 49 who participated in the Colorado Adoption/Twin Study of Lifespan Behavioral Development and Cognitive Aging (https://www.colorado.... exercise aging heart disease genetics exercise snacks

Watch nowNearly 50 million people worldwide live with Alzheimer’s disease or another form of dementia — a number projected to triple in the coming decades. However, a recent study suggests the number could be even higher, as much as 40 percent more than previous estimates. Researchers analyzed data from the English Longitudinal Study of Ageing, a long-term study of older adults living in England and Wales. They identified dementia cases from among more than 90,000 people. Then, they analyzed how dementia incidence changed over time based on age, sex, and education. They found that dementia incidence ... alzheimer's aging dementia
Read moreA Western diet pattern, characterized by a low intake of fruits and vegetables and a high intake of sugar and processed foods, promotes the development of obesity and metabolic disease. Time restricted eating has been shown to decrease weight and improve metabolic health in humans. However, factors such as age and sex modulate both susceptibilty to obesity and likelihood of responding to weight-loss treatments. Authors of a new report found that male mice experienced greater metabolic benefit from time-restricted feeding than females. Time-restricted eating, the practice of limiting food intak... cholesterol fasting fat muscle sugar time-restricted eating weight loss lipopolysaccharide
Read moreThe brain shrinks with age, a process called brain atrophy, and a faster rate of shrinkage is associated with dementia and cognitive and functional impairments. Heart disease risk factors such as high cholesterol, diabetes, and hypertension are common in industrialized populations and increase the risk of brain atrophy. Findings of a recent report compare rates of brain atrophy in industrialized and non-industrialized populations. The indigenous Tsimane people of lowland Bolivia live by foraging, hunting, fishing, and horticulture in the Amazon basin. The Tsimane have the lowest prevalence of ... aging
Read moreResearchers in the field of aging have posited several theories to explain how and why the body ages. One of these theories, the somatic mutation theory of aging, is based on the idea that DNA damage accumulates over time – the result of day-to-day living and oxidative stress. A variety of mechanisms within cells can repair DNA damage and prevent potentially harmful mutations. These repair mechanisms become less efficient as the body ages, however, promoting age-related disease and decline. A new study suggests that loss of the body's capacity to repair itself starts during adolescence and cou... aging dna damage
Read moreLimiting food intake and engaging in exercise are highly effective strategies for weight loss. People who are obese are often sedentary, however, due to physical limitations and a lack of motivation to exercise. Compelling findings from a new study in mice suggest that ghrelin, a hormone linked to appetite, may increase motivation to engage in exercise. Ghrelin, which is produced primarily in the stomach, stimulates appetite, increases food intake, and promotes fat storage in mice and humans. It is often referred to as the "hunger hormone" and is linked to reward-driven behavior. Previous stu... exercise fasting ghrelin time-restricted eating dairy weight loss
