Background
Maintaining weight loss is a common challenge for many people. A new study from Norway suggests that persistent hunger may be a key factor behind weight regain.
Key Findings
The researchers found that even after weight loss, participants still had elevated levels of hunger hormones (such as ghrelin) and lower levels of satiety hormones (such as PYY). This hormonal imbalance causes the brain to continue receiving hunger signals, leading to increased food intake.
- Elevated hunger hormones: Ghrelin remains high even after weight loss, stimulating appetite.
- Reduced satiety hormones: Makes people feel hungrier after meals.
- Metabolic adaptation: The body's metabolism slows down after weight loss, further increasing the risk of weight regain.
Recommendations for Weight Losers
The study highlights the importance of long-term hunger management after weight loss. Experts suggest that individuals should emphasize intake of protein and dietary fiber to enhance satiety, and incorporate strength training to help maintain muscle mass and basal metabolic rate.
