Summary
Time-restricted eating (TRE) and daily calorie restriction (CR) both led to weight loss in adults with obesity. However, neither TRE nor CR significantly improved sleep quality, duration, insomnia, or sleep apnea risk over one year.
Area of Science:
- Nutrition Science
- Sleep Medicine
- Obesity Research
Background:
- Obesity is linked to poor sleep quality and increased risk of sleep apnea.
- Dietary interventions like time-restricted eating (TRE) and calorie restriction (CR) promote weight loss, but their effects on sleep are not fully understood.
Purpose of the Study:
- To compare the effects of 8-hour time-restricted eating (TRE) versus 25% daily calorie restriction (CR) on sleep parameters in adults with obesity.
- To assess changes in sleep quality, duration, insomnia severity, and obstructive sleep apnea risk over a 12-month period.
Main Methods:
- A randomized controlled trial involving 90 adults with obesity.
- Participants were assigned to an 8-hour TRE group, a CR group, or a control group for 12 months.
- Sleep parameters and weight loss were measured at baseline and 12 months.
Main Results:
- Both TRE and CR groups achieved significant weight loss compared to the control group (TRE: 4.61 kg; CR: 5.42 kg).
- There was no significant difference in weight loss between the TRE and CR groups.
- No statistically significant improvements were observed in self-reported sleep quality, sleep duration, insomnia severity, or risk of obstructive sleep apnea in either the TRE or CR groups compared to controls.
Conclusions:
- Weight loss achieved through TRE and CR over one year did not significantly impact sleep quality, duration, insomnia severity, or obstructive sleep apnea risk in adults with obesity.
- These findings suggest that while TRE and CR are effective for weight management, they may not be sufficient to improve sleep parameters in this population.

01:13Insufficient Sleep and Sleep Deprivation
134
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:19Management of Insomnia
234
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

01:11Understanding Sleep
220
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

387
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...
