These discoveries about orexin cells and their dietary sensitivities sound like good news for people who want to expand the reach of their free will into the subconscious.

Indeed, the idea of controlling orexin neurons through conscious dietary choices is very attractive for people suffering from insomnia, or low motivation to move. However, it is still too early in our research to justify eating a bag of sugar to aid sleep. There is still a long way to go before designer diets that control our brain states could be deemed safe and effective.

Could switching to a ketogenic diet reduce asthmatic symptoms? Researchers identify digestive-brain axis which controls food choice. The body rapidly regulates sugar levels inside our bodies, so simply eating sugar may not be enough to inhibit orexin cells for the whole night.

Besides, too much sugar can lead to dangerous disorders, such as diabetes. Conversely, overstimulating the orexin cells can lead to unpleasantly active brain states, such as anxiety. Our research now aims to understand how multiple lifestyle factors and disease risks can be integrated to produce safe control over orexin cells and other subconscious brain processes that often rule our lives.

Taken together, our results suggest that body weight and dietary condition both contribute to changes in total wake time. Body weight is, however, not associated with wake bout instability in the active phase, unlike dietary condition.

We hypothesized that acute diet-induced alterations to energy balance might induce changes to both weight and sleep architecture. Therefore, the immediate differences in caloric intake following the diet switch contributed to the changes in energy balance and body weight, but it is less clear how caloric intake per se affects sleep and wakefulness.

A One week of HFD significantly increases body weight in RC-fed mice, whereas mice with DIO fed RC for 1 w significantly decreases body weight. B Caloric intake was similar among all four groups before the diet switch Week 8; Day 0 and 1 w after the diet switch Week 9; Day 7 post-diet switch.

C,D Acute HFD increases NREM sleep at the expense of wakefulness. Conversely, feeding RC to overweight mice enhances wakefulness and decreases NREM sleep. E,F Acute HFD fragments wakefulness, while reverting mice with DIO to RC consolidates wakefulness in the dark phase.

One week after the diet switch, there is a strong correlation between body weight change and wake change G and wake to NREM transitions in the dark phase H.

DIO, diet-induced obesity; NREM, nonrapid eye movement; RC, regular chow. We also assessed how absolute wakefulness was affected at Week 9 between these comparisons. These changes to total wake time were again accompanied by concomitant changes in NREM sleep time Figure S2B.

We found large changes to bout architecture 1 w following the diet switch, with acute HFD fragmenting and acute RC consolidating both sleep and wakefulness. We observed similar trends for NREM bout number and length during the dark phase Figure S2C and S2D.

We also analyzed how absolute bout architecture compared at Week 9. One week of HFD trended toward fragmenting wakefulness during the dark phase, but 1 w of RC significantly consolidated wakefulness and NREM sleep during the dark phase Table 2.

Thus, HFD or RC consumption for 1 w can significantly alter sleep and wakefulness. Previous studies have shown that switching mice with DIO back to RC for at least 4 w can rescue sleep behavior and even cognitive ability.

We found sleep architecture was similar between groups of mice that consumed the same diet during the final week, regardless of their chronic diet. We analyzed delta power using two different methods, both of which are commonly used in sleep research.

We performed sleep deprivation during ZT 0—6 by a combination of novel enrichment and gentle handling. Thus, we found no evidence to indicate that sleep homeostasis is affected by either acute or chronic dietary manipulations.

NREM sleep delta power 1—4 Hz during undisturbed sleep recordings A,B and following 6-h sleep deprivation C,D. Total wake E , NREM F , and REM sleep G during the sleep deprivation Zeitgeber time ZT 0—6 and recovery period ZT 6— There are no differences between any dietary condition comparisons, indicating that sleep homeostasis in unaffected by dietary changes or diet-induced obesity.

Additionally, we found no differences in recovery sleep following forced wakefulness, indicating that the changes observed cannot be explained by alterations in sleep homeostasis.

Multiple reports, including this present study, have found that wakefulness is decreased in obese animal models. Both strains of transgenic leptin-deficient mice spent less time in REM sleep compared with wild-type controls. There are a few methodological differences that may explain these disparities.

First, DIO experiments require long periods of social isolation while weight gain manifests, whereas genetically induced obese animals are only isolated directly prior to sleep recordings. Younger animals are more susceptible to depressive-like symptoms following stress, such as isolation.

Future studies could use advanced sleep recording techniques i. Additionally, it is possible that REM sleep is affected by acute diet switch.

Previous studies have consistently found worsened wake and sleep fragmentation in both genetically obese animals and those with DIO. Conversely, DIO mice acutely consuming RC exhibit normalized bout fragmentation during the active phase.

Multiple linear regression analysis revealed that the dietary condition, but not the animals' body weight, was significantly associated with the number of short wake bouts Table 3. Thus, acute diet switch drove significant, bidirectional changes to wake bout stability independent of body weight.

Prior studies found less dramatic changes to bout length and number at earlier time points. Nonetheless, diet-induced effects on fragmentation are consistent between studies, although future work needs to confirm the onset of this phenotype.

Genetically obese mice are fed a standard chow diet, but are in a state of perpetual weight gain and obesity. Last, our linear regression analysis determined that both body weight and dietary condition significantly contribute to modeling wake time. Interestingly, only dietary condition was significantly related to wake fragmentation, specifically the number of short wake bouts during the dark phase.

Nonetheless, future work with different diets e. Increased delta power 1—4 Hz following sleep deprivation indicates the depth and intensity of sleep, and is the current gold standard for testing sleep homeostasis. Chronic HFD increased NREM sleep and decreased wakefulness during the beginning of the dark phase, when the activity of mice peaks.

Further, wake and NREM fragmentation increased during the dark phase. Acute diet switch also affected total wake and NREM time with no effect on REM , but these effects were not localized to a particular time of day.

Taken together, we hypothesize that HFD induces wake bout instability during the active phase, which leads to increased total sleep time across the day.

Orexin or hypo-cretin signaling is necessary for wake bout stability, because disruption of this pathway induces narcolepsy. There are some inherent limitations with this study design.

First, we tracked caloric intake throughout the study, but we did not measure energy expenditure and locomotor activity. Without information about both intake and expenditure, energy balance cannot be directly quantified.

One possibility is that caloric intake was overestimated for RC-fed conditions because some mice will shred this diet, making accurate measurements difficult.

However, caloric intake may indeed be similar at these time points, suggesting that changes in caloric expenditure drives the energy imbalance and body weight changes. Future studies need to measure all aspects of energy balance by directly assessing caloric intake, energy expenditure, and locomotor activity.

Second, we did not determine if sleep and wakefulness are affected earlier than 1 w after dietary manipulations. Last, there are important differences between the control RC diet and the HFD. The HFD has a much better taste than the RC, which affects motivated and hedonic food intake.

Future studies need to control for the diet content, consistency, and presentation e. In summary, we have found that short-term changes to diet bidirectionally affect energy balance i.

These findings are consistent with obese patients who, after undergoing bariatric surgery, report improvements in sleepiness and vigilance despite still being quite obese.

Traditional risk factors for obesity and the metabolic syndrome, such as excess energy intake and lack of physical activity, cannot fully explain the high prevalence of these conditions. Insufficient sleep and circadian misalignment predispose individuals to poor metabolic health and promote weight gain and have received increased research attention in the past 10 years. wakefulness and diet Sleep Science ciet Practice Increased awareness state 7Article number: 8 Nad this article. Metrics details. Andd quality and its effects have become wakefulnes public concern over wakefulness and diet last few years. While the prevalence of sleep disorders was increasing, several studies have linked diet and physical activity as a cause of it. Indeed, many people complain about their sleeping problems without considering their lifestyle as a cause. This leads the efforts to focus on these principal factors and find their specific effect. The study aims to map out the research on the effect of nutrition and physical activity on sleep quality.
