Link between Sleep deprivation and weight gain – reliv
Perhaps one of the lesser-known facts about weight loss is the importance of proper sleep. No amount of exercise and diet control can undo the damage done by sleep deprivation. In fact, controlling your diet and exercising can make weight loss as challenging as swimming against the current if you don’t sleep well.
Here’s why :
1. Increased Cortisol Levels: Sleep deprivation increases cortisol levels, also known as the stress hormone. Cortisol causes fat deposition in the body, especially around the belly area..
2.Reduced Insulin Sensitivity: Sleeplessness decreases the sensitivity of insulin receptors in the body, leading to less efficient assimilation of glucose. This results in overall lethargy, decreased energy levels, and fat deposition.
3. Increased Ghrelin Levels: Sleep deprivation increases the hormone ghrelin, which stimulates hunger, leading to a tendency for night snacking.
4. Decreased Leptin Levels: Sleeplessness decreases the hormone leptin, which causes a sense of fullness in the stomach, making us feel food-deprived.
5. Aggravation of Hormonal Imbalances: Sleep deprivation can aggravate hormonal imbalances, especially in people with underlying disorders like PCOS and diabetes, causing weight gain..
6. Weight Gain During Menopause: Sleep deprivation during menopause can lead to sudden weight gain despite diligent exercise and fasting.
7. Increased Risk of Obesity: There is an increased risk of obesity due to sleep deprivation.
8.
Impaired Decision Making: Decision making is highly impacted during sleep deprivation. This, coupled with emotional imbalance, can lead to comfort eating and unnatural cravings for non-nutritious food.
9.
Overall Lethargy: The overall lethargy caused by sleep deprivation can lead to skipping physical activities and exercise.
10. Disruption of Circadian Rhythms: Sleeping at unnatural hours, not in accordance with the body's circadian rhythms, has almost the same effect as not sleeping at all.
Thus, a proper night's sleep—around 7-8 hours—is mandatory if you wish to look fit and young. It's a foolproof recipe for weight loss.
