If you find brain-draining activity turns you into an eating machine, exercise could help curb your hunger, a new study has found.
The University of Alabama study asked students to complete a challenging exam, then either exercise or rest for 15 minutes. Researchers then treated the students to an all-you-can-eat pizza lunch.
In a separate session, the students also rested and then ate pizza to allow the researchers to get a baseline for the students’ appetite.
You might have thought the exercisers would be hungrier, but the opposite was true: those who had relaxed after the exam ate about 400 kilojoules more than their baseline.
In contrast, those who exercised ate about 100 kilojoules less than their baseline, plus they burned kilojoules during their 15 minutes of high-intensity interval training, reducing their overall energy intake even further.
