Aging Experts Link Muscle Loss to Slower Metabolism and Higher Diabetes Risk
Physicians explain that cellular energy decline drives age-related symptoms, recommending strength training to maintain glucose control.

Metabolic decline in older adults is driven by the loss of cellular energy rather than simple weight gain, according to medical experts.
Dr. Rhea Rogers, a board-certified physician, described metabolism as the body’s primary energy system. She stated that mitochondria act as battery packs that supply energy to cells. Rogers noted that organs with high energy demands, such as the brain and heart, show signs of depletion sooner. She said that reduced energy production leads to symptoms like brain fog, fatigue, and general lethargy.
Gerontologist Sam Cradduck compared the body’s metabolic function to a power plant. He observed that public understanding often limits metabolism to weight management. However, Cradduck noted that metabolic changes also affect how older individuals process medications. Rogers described the aging process as a progressive loss of cellular energy. She said this decline explains the physical symptoms commonly associated with getting older.
The loss of muscle mass, known as sarcopenia, plays a central role in this decline. Rogers explained that age-related hormonal changes contribute to the loss of muscle mass. Amy O’Rourke, an aging expert, said that many people focus on weight loss and ignore strength. O’Rourke recommended strength training two to three times per week to preserve muscle. She advised younger adults to begin strength training immediately to prevent a cascading loss of function later in life.
Muscle tissue is directly connected to glucose regulation. Rogers explained that muscles must absorb glucose to use it for energy. She defined insulin resistance as the inability of muscles to take up glucose. Rogers said that this condition is the starting point for prediabetes and type 2 diabetes. She noted that type 2 diabetes is appearing in younger populations due to metabolic inflexibility. This term describes the inability of cells to switch between burning fat and carbohydrates for energy.
Rogers attributed the loss of metabolic efficiency to environmental toxins and inflammation. She listed muscle stimulation, inflammation control, toxin removal, nutrition, and sleep as key components of health. Aging well coach Katherine Ambrose said the focus should be on creating energy and health rather than managing disease. The experts emphasized that maintaining muscle mass supports overall vitality and physical capability.
