Researchers found that aging triggers the appearance of specialized stem cells in abdominal tissue that markedly increase the body’s capacity to create new belly fat. This provides a likely biological explanation for midlife waistline expansion and points to those stem cells as a promising target for future anti-obesity treatments. The mechanism could help explain variable responses to weight-loss drugs, is relevant to efforts to reduce age-related liver fat, and reinforces midlife as a key window for lifestyle or drug interventions.
