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:
- 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.
- 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.
- Increased ghrelin levels: Sleep deprivation increases the hormone ghrelin, which stimulates hunger, leading to a tendency to overeat.
