Young woman sleeping weight and sleep


The link between weight and sleep is an important one. A good night’s sleep is essential, both for overall health and for effective weight loss. If you’re following a weight loss plan in Orlando, make sure you get close to eight hours of sleep each night. Sufficient sleep balances your hormone levels, which in turn can support fast weight loss.

You can hear more about how sleep affects your hormone levels when you watch this video. It features an interview with a bariatric specialist. She explains that when a person is sleep-deprived, his or her cortisol levels rise. Cortisol is a hormone that plays a role in storing fat in the body. In other words, not getting enough sleep can jeopardize your weight loss. Additionally, fatigue can sap your willpower, which means that you might be less likely to make healthy choices during the day if you didn’t get enough sleep the previous night.

Key Points

There is a complex relationship between weight and sleep that has been extensively studied.  It is difficult to establish a direct cause-and-effect relationship. But research suggests that weight and sleep are connected and can influence each other in various ways. Here are some key points regarding the link between weight and sleep:

  1. Obesity and sleep apnea: Obesity is a significant risk factor for sleep apnea, a sleep disorder characterized by pauses in breathing or shallow breaths during sleep. Excess weight can lead to the narrowing or blockage of the airway, resulting in disrupted breathing patterns. Sleep apnea, in turn, can further contribute to weight gain due to sleep fragmentation, hormonal changes, and decreased physical activity.
  2. Sleep duration and weight gain: Studies have found an association between shorter sleep duration and an increased risk of weight gain and obesity. Insufficient sleep is believed to disrupt the balance of hormones involved in hunger regulation. This leads to more hunger, cravings, and a preference for calorie-dense foods. Sleep deprivation may also reduce motivation for physical activity, further contributing to weight gain.
  3. Hormonal regulation: Sleep plays a role in regulating various hormones, including leptin and ghrelin, which are involved in hunger control. Lack of sleep can disrupt the balance of these hormones. This leads to increased feelings of hunger and decreased feelings of satiety. This hormonal imbalance may cause overeating and weight gain.
  4. Circadian rhythm and metabolism: Disruptions to the body’s internal clock, known as the circadian rhythm, can affect metabolic processes and potentially contribute to weight gain. Irregular sleep patterns, such as shift work or chronic jet lag, can disrupt the circadian rhythm, leading to metabolic dysregulation and an increased risk of obesity.
  5. Lifestyle factors: Unhealthy lifestyle habits, such as poor diet and too much sitting, can contribute to both weight gain and poor sleep quality. Certain dietary choices, like consuming excessive caffeine or late-night eating, can interfere with sleep. Additionally, lack of physical activity can negatively impact sleep quality, making it harder to maintain a healthy weight.


It is important to note that the relationship between weight and sleep is complex and can vary among individuals. While these associations have been observed in research studies, they do not necessarily indicate a direct causal relationship. Maintaining a healthy weight and prioritizing good sleep hygiene are both essential for overall well-being. If you have concerns about your weight or sleep, it is good advice to consult with a healthcare professional for personalized advice and guidance.
