World Obesity Day 2026 is being celebrated on 4 March to make people aware about obesity and the diseases caused by it. The common belief about obesity is that a person who eats more increases in body fat. Medical science considers overeating as one of the reasons along with many other reasons. Especially in those people whose metabolism is not good. But there are many other reasons for increasing obesity. If you know these then it is possible that you may not become a victim of obesity or you may be able to control it in time.
Dr. Deepak Kumar Suman, Senior Resident at Safdarjung Hospital, Delhi show that obesity One reason for growth is eating more, but this is not the case in every case. Some people eat less food, but their weight still increases. All this happens due to hormonal imbalance, mental stress, lack of sleep. In many people, weight increases rapidly due to thyroid disorders, PCOS or insulin resistance. In the last few years, the number of patients whose weight gain is due to thyroid or insulin resistance has increased.
How lack of sleep increases obesity
Dr. Deepak says that if a person sleeps less than 5 hours every day, the level of ghrelin hormone in his body starts deteriorating. This hormone increases appetite rapidly. Due to increase in appetite, a person eats more and this causes weight gain. It is also seen that people who do not get enough sleep gradually develop the problem of increasing obesity, although this is not the case in every case, but still it is a big reason.
Similarly, mental stress also causes increase in obesity. This is because mental stress increases the level of cortisol hormone in the body. A related increase in this hormone increases the fat around the stomach. This fat then also causes many other diseases.
