Yo-Yo Dieting Shown to Cause Lasting Changes in Gut Bacteria, New Study Finds
A groundbreaking new study from France suggests that cycles of yo-yo dieting—the common pattern of repeatedly losing and regaining weight—can induce lasting alterations in the gut bacteria of mice, potentially fueling unhealthy eating patterns and complicating long-term weight management. These findings may hold profound implications for Thai people navigating diet trends and obesity challenges, highlighting the hidden impacts of diet cycling beyond calorie balance or willpower alone (ScienceAlert).
Yo-yo dieting, also known as “weight cycling,” is a familiar struggle both in Thailand and worldwide. Repeated attempts at restrictive diets, followed by binge episodes and regaining weight, are often credited to metabolic adaptations or psychological factors. However, the recent study led by researchers at the University of Rennes and Paris-Saclay University breaks new ground by pointing to durable biological changes within the gut microbiome—the dense community of trillions of bacteria that populate our intestines—as the root of this problem.
