Weight not reducing despite diet and exercise? know the scientific reasons behind it

New Delhi (The Uttam Hindu): Increasing body weight has become a major concern in today’s time. People go to the gym, follow strict diet plans, and try various methods to stay fit, yet many fail to lose weight. This often leads to frustration and giving up. Scientific research points to several underlying reasons behind this issue.

According to studies, lack of proper sleep plays a key role. When a person does not get enough sleep, hormones like ghrelin and leptin—responsible for hunger and satiety—get affected. Sleep deprivation increases appetite, leading to overeating. At the same time, the stress hormone cortisol rises, which accelerates fat storage. Experts recommend getting at least 7–8 hours of quality sleep daily.

Another major factor is dehydration. Many people do not drink enough water throughout the day, which directly impacts metabolism. Research suggests that adequate water intake can slightly boost calorie burning and help control hunger. It also helps flush toxins from the body and improves digestion. Lack of water can slow down the weight loss process.

Mental stress is also a significant reason. Stress increases cortisol levels, which leads to fat accumulation, especially around the abdomen. It can also trigger emotional eating, where individuals consume more food in response to stress. Practices like meditation, yoga, or engaging in enjoyable activities can help manage stress effectively.

Lack of balanced nutrition is another important factor. In an attempt to lose weight, many people drastically reduce food intake or ignore essential nutrients. However, the body requires proper amounts of protein, fiber, vitamins, and minerals. Protein helps build muscles and control hunger, while fiber improves digestion and keeps you full for longer. Nutritional imbalance can cause the body to conserve energy, making weight loss difficult.

Lastly, insufficient physical activity can hinder weight loss. Diet alone is not enough—keeping the body active is equally important. Research shows that people who engage in regular physical activity have better metabolism and burn more calories. At least 30 minutes of daily exercise, such as brisk walking, yoga, or cycling, can significantly support weight loss.
