Should you smell chocolate before working out? Here's what science says
Findings are promising, but experts urge caution
Smelling dark chocolate before exercise may help people perform more repetitions during strength training, according to a new study. However, experts say the findings are preliminary and should not replace proper pre-workout nutrition.
The research suggests the aroma of chocolate could temporarily reduce hunger and improve workout performance, but larger studies are needed to confirm the results.
Dark chocolate scent linked to better workout performance
Researchers asked 23 healthy young men who regularly performed strength training to complete leg extensions after smelling liquefied dark chocolate, milk chocolate or a water-based control.
Participants completed an average of 18 more leg extensions after smelling dark chocolate than after the control. Those exposed to milk chocolate also performed better, averaging about nine additional repetitions.
Researchers also found that participants who smelled dark chocolate reported feeling less hungry, more full and had a lower desire to eat.
Why the aroma may help
Researchers believe the smell of dark chocolate may activate brain regions linked to memory, reward and appetite, making the body feel as though food is on the way.
The response could temporarily reduce hunger and help people push harder during exercise, while the pleasant smell of milk chocolate may boost motivation.
Experts urge caution
Despite the findings, experts say it is too early to recommend smelling chocolate before workouts.
The study involved only 23 healthy young men and examined a single strength exercise, making it unclear whether the results apply to women, older adults or other forms of physical activity.
Experts also stress that people should eat a nutritious meal or snack before exercising rather than relying on scents to improve performance, as adequate nutrition remains essential for fuelling workouts and supporting overall health.
