Metabolism shifts as bodies lose muscle and gain fat
Experts explain how age-related physical changes affect energy levels and how communities are adapting to later-life health needs.

The body's ability to process energy changes as people get older, driven by a shift in tissue composition. Dr. Rhea Rogers, a board-certified physician, explained that individuals typically gain fat and lose muscle mass over time. This transition directly impacts how the body utilizes glucose for fuel.
Rogers described metabolism as the body's power plant, noting that every organ maintains its own energy supply. When an organ with high energy demands loses that power, symptoms appear more quickly. She cited changes in the eyes and ears as examples of how this depletion becomes visible in older adults.
Beyond physical health, the source highlights how people navigate the end of life. Gerontologist Sam Cradduck stated that individuals facing death do not need to feel pressured to remain strong or manage the emotions of those around them. Cradduck emphasized that the dying person is entitled to receive support rather than provide it.
Katherine Ambrose, an aging well coach, noted that every person handles the final phase of life differently. She identified grief, unfinished business, and relationship dynamics as common factors people must address. The goal is to allow individuals to set boundaries and care for themselves during this period.
Laura Lyster-Mensh works as a death doula at Historic Congressional Cemetery in Washington, D.C. Her role involves promoting what she calls death positivity. She helps visitors engage in healthy conversations about mortality within the national landmark.
Community activity also serves as a tool for maintaining health and social connection. Krista Catwood founded the Food Court 5000, a group of mall walkers who gather every Sunday morning. They cover three and a half miles of power walking at the Lloyd Center mall in Oregon.
Catwood said the group has become local celebrities at the mall. She designed the activity to be silly, social, and shared, incorporating '90s nostalgia through specific attire. Participants often wear spandex, neon gear, and scrunchies during their walks.
