A new study from University of Sussex in England concluded that smelling lemons will makes you feel slimmer. But it won’t make you loose any weight. Perception is reality right? So guess it’s worth a try. The study also found that vanilla has the opposite effect. The scent makes you feel heavier. This comes from the association our brain makes with different smells. Vanilla reminds us of our favorite sweets while lemons make us think of freshness.
