How Our Sleep Cycle Impacts Our Weight, Expert Answers

Gaining weight is often easier than losing weight. When a person thinks about weight loss, diet and exercise are the two main factors that come to mind. But sleep is the third main factor that needs to be focused on equally, but is often neglected. While thinking about losing weight one focuses on things that might be the reason for weight gain, but tends to forget the impact of sleep deprivation on weight gain.

What happens when one doesn’t sleep enough?

As told by Dr. Harihara Murthy, Consultant ENT surgeon at Apollo Spectra Hospital, Bangalore, here are some things that you would experience:

Cravings: It is seen that when a person is tired due to lack of sleep, they tend to crave more food. When a person is tired, the body produces a hunger-stimulating hormone called ghrelin, which results in craving high-fat and carbohydrate-rich foods.

Too Exhausted To Exercise: People who are sleep deprived tend to rarely hit the gym. Due to lack of sleep, the body feels very exhausted. Even sleeping for more than what is required can make a person feel very exhausted to work out or do any kind of physical activity. One needs to at least exercise for 10 minutes daily to keep the body healthy.

Side effects of being a night owl: When a person stays up late at night, tends to eat more and craves late-night snacks, which result in gaining weight. Due to lack of proper sleep, the metabolism slows down which doesn’t help in burning calories properly. It is always recommended to sleep properly for a minimum of six to eight hours for a healthy body.
