The Claim
Eight days of sleep restriction does not significantly alter activity energy expenditure in healthy adults, suggesting that the increase in caloric intake observed during sleep loss is not compensated by an increase in physical activity.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When people don’t get enough sleep for eight days, they don’t end up moving more to burn off the extra calories they eat—so they’re likely to gain weight just from eating more, not from being lazy.
See the scientific wording
Sleep restriction for 8 days does not significantly alter activity energy expenditure in healthy adults, indicating that increased caloric intake during sleep loss is not offset by increased physical activity.
What the research says
1 studyStudy: Effects of experimental sleep restriction on caloric intake and activity energy expenditure.
When people slept less for 8 days, they ate more but didn’t move around any more than usual — so they burned the same amount of energy despite eating extra calories, which could lead to weight gain.
