Sleeping:How Does It Affect Eating?
Alexander Paulzen
About Sleeping
At least 8-9 hours
Busy People-5 hours
Weight Gain/Obesity (unlimited access)
Requires Energy-Staying up
Sleeping-Burning Calories
Experts Said...
Extra sleeping, No weight loss.
May help with healthy weight and obesity
Getting less sleep=No weight gain
Insufficient sleep, leads to eating more than necessary
Kenneth Wright-leading the research
Hypothesis, not clear
Making An Experiment
Monitoring 16 young&healthy adults
In a sealed room-researchers measuring energy used (O2 CO2)
Everyone: first 3 days-sleeping 9 hours&eating meals with necessary calories
Than, split into 2 groups: 1-5 days with 5 hours sleep, 2-5 days with 9 hours sleep
Making An Experiment Continued
Both groups: large meals, snack throughout the day (fruit-potato chips)
Switched
5 hours: 5% more energy burned
5 hours: consumed 6% more calories
5 hours: eat smaller breakfast, eat a lot after-dinner snacks
Evening snacks-more than an individual meal
Adds to evidence: Overeating at night=weight gain
Conclusion/FindingsPeople that are sleep restricted: Eat during their minds night time (not designed to)
Men and women reacted differently to food
Men: gained weight even if they had a good sleep (when they could eat as much as they want)
Women: Maintained their weight after a good sleep (even though they could eat as much as they want)
Both gained weight-5 hours
Research funded by health institutions
