Does sleep promotes weight loss?

 Sleep is essential for weight loss and overall metabolic function. Here are some key points from the search results:

  • Hormones: Sleep helps regulate hormones, including leptin and ghrelin, which control appetite and metabolism. Unhealthy sleep patterns lead to lower levels of leptin, which is closely linked to weight loss

    .
  • Fat burning: Melatonin, our sleep hormone, is released when we are in a deep sleep and helps with fat burning
    2
    .
  • Cravings: Poor or limited sleep can drive metabolic dysfunction and make healthy weight management more difficult through multiple mechanisms, including changes in appetite and satiety signaling hormones and neurocognitive processes that influence eating behaviors, which can result in cravings for ultra palatable foods and increased caloric consumption

    .
  • Dietary compliance: Poor sleep undermines dietary efforts to reduce weight by altering the levels of the appetite-regulating hormones, leading to a reduction in dietary compliance
    4
    .
  • Metabolic rate: An increase in sleep duration and correction of sleep disorders may be accompanied by a better balance of the hormones that regulate appetite, with enhanced glucose tolerance, and a reduction in the level of cortisol, which can improve metabolic rate

    .
  • Weight loss: When dieters cut back on sleep over a 14-day period, the amount of weight they lost from fat dropped by 55%, even though their calories stayed equal. They felt hungrier and less satisfied after meals, and their energy was zapped

    .
In summary, deep sleep promotes weight loss by regulating hormones, enhancing fat burning, reducing cravings, and improving overall metabolic function, aiding in weight management.
