Fat Cells' Memory May Explain Yo-Yo Dieting Challenges
New research suggests that fat cells have a 'memory' of past obesity, which may contribute to the yo-yo dieting effect where weight is regained after loss. This biological memory, identified through studies on human and mouse fat tissue, involves epigenetic changes that affect how fat cells respond to nutrients. The findings indicate that maintaining weight loss is challenging because fat cells tend to revert to their previous obese state. This research could lead to improved weight management strategies, although the memory may fade over time with sustained weight maintenance.
