When you’re tired or stressed, you’re more likely to get smacked with cravings and reach for unhealthy snacks. But what if simply smelling certain essential oils could help you think clearly, overcome those cravings, and stay on the healthy eating bandwagon?

The next time cravings threaten to derail your progress, turn to the following essential oils, which can help curb your appetite, boost your alertness, and make you feel energized.

For Hanger, Try Citrus

Bergamot essential oil, which helps boost mood and sense of well-being, may help if emotional eating is undermining your diet. Studies also report that bergamot reduces the production of the stress hormone cortisol, which has been linked to difficulty dropping stubborn belly fat. If you’re feeling particularly stressed, diffuse the essential oil to help you avoid mindless nibbling.

Studies have also discovered that the sweet aroma of grapefruit essential oil not only provides an instant mood lift, but that it contains a natural compound called nootkatone that can help diminish cravings. Simply inhaling this bright citrus oil can reinvigorate you so you can focus on your goals.

Lemon essential oil is another instant mood brightener. After all, who doesn’t perk up after a refreshing glass of lemonade or a squeeze of lemon in icy spring water? Diffuse some lemon essential oil when you need a pick-me-up or some extra motivation, or even add a few drops to your sports balm to relieve sore muscles after exercising.

(Though not a citrus oil, ginger essential oil can help soothe you if your cravings stem from stress.)

For Water Retention, Try Juniper And Cypress

Juniper essential oil and cypress essential oil are considered purifying because they help flush excess water out of the body. Combine one or both with grapefruit essential oil for an uplifting aromatic massage blend.

For Cravings, Try Rosemary And Peppermint

The culinary herbs rosemary and peppermint enhance flavors and elevate mood, and their essential oils are equally as uplifting. One scientific study reports that, when inhaled every two hours, peppermint even goes a step further and lowers hunger levels.

When the urge to overeat strikes, simply diffuse rosemary or peppermint and breathe deeply.

How To Safely Enjoy Essential Oils

Essential oils are best used as aromatics or applied to the skin topically. Even the purest organic oils can be toxic if swallowed. If you have sensitive skin, do a skin patch test before blending up massage oil by applying a small amount of essential oil to a small patch of skin and looking out for any irritation.
