Study Reveals Genetics Behind Weight Loss Resistance

Recent research published in Nature reveals that fat cells can retain an 'epigenetic memory' of past obesity, complicating weight maintenance post-weight loss. This study indicates that obesity alters gene expression in fat cells, making them more efficient at storing fat, which could lead to weight regain. Additionally, many prevalent weight loss methods, such as extreme caloric restriction and unregulated diet pills, pose significant risks to health, promoting nutrient deficiencies and muscle loss. Experts emphasize the importance of addressing underlying factors like hormonal imbalances and chronic inflammation, as highlighted by Dr. Shilpa Sayana, who also advocates for increasing dietary fiber. Furthermore, misinformation regarding weight loss persists in medical circles, with outdated advice still being shared by healthcare providers. New concepts like chronobiology and intermittent fasting are emerging as more effective strategies for weight management.
