Control of Eating Behavior Using a Novel Feedback System04:48

Control of Eating Behavior Using a Novel Feedback System

11.5K
Subjects eat food from a plate placed on a scale connected to a computer that records the weight loss of the plate during the meal. Feedback on the computer screen allows the subject to adapt her/his eating behavior to reference curves thus normalizing body...

Low-Cost Automated Flight Intercept Trap for the Temporal Sub-Sampling of Flying Insects Attracted to Artificial Light at Night

3.0K
To study the impacts of artificial light at night (ALAN) on nocturnal flying insects, sampling needs to be confined to nighttime. The protocol describes a low-cost automated flight intercept trap that allows researchers to sample at user-defined periods with increased...

Binge Eating Disorders01:23

Binge Eating Disorders

428
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

478
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Fat Preference: A Novel Model of Eating Behavior in Rats

13.7K
Dietary fat content influences both energy intake and body fat composition in mammals. By examining rats’ preference for high fat food in a series of choice experiments, it is possible to test genetic differences and pharmacological interventions on their preference for high fat...

The Power of Interstimulus Interval for the Assessment of Temporal Processing in Rodents

7.3K
Temporal processing, a preattentive process, may underlie deficits in higher-level cognitive processes, including attention, commonly observed in neurocognitive disorders. Using prepulse inhibition as an exemplar paradigm, we present a protocol for manipulating interstimulus interval (ISI) to establish the shape of the ISI function to provide an assessment of temporal...

Area of Science:

  • Nutrition Science
  • Chronobiology
  • Occupational Health

Background:

  • Shift work disrupts circadian rhythms, potentially impacting dietary habits and chronic disease risk.
  • Understanding the nutritional intake patterns of shift workers is crucial for developing targeted health interventions.

Purpose of the Study:

  • To examine differences in energy intake, eating frequency, and dietary guideline adherence among shift workers based on shift type (night vs. day).

Main Methods:

  • Shift workers recorded food and beverage intake over four days, including night shifts and day shifts/days off.
  • Statistical analyses (ANOVA, GEE) compared dietary intake parameters between night shifts and day shifts/days off.

Main Results:

  • No significant differences in total daily energy intake or adherence to dietary guidelines were found between night shifts and day shifts/days off.
  • Shift workers consumed less energy per eating occasion during night shifts and exhibited higher total sugar and lower saturated fat intake compared to day shifts/days off.
  • Day shifts/days off were characterized by three main meals and a prolonged fasting period.

Conclusions:

  • Shift work influences the macronutrient composition and timing of food intake, with implications for metabolic health.
  • Further research is needed to explore whether reducing eating occasions and incorporating fasting periods can improve metabolic health in shift workers.
