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
