Can Essential Oils Help Me Lose Weight?

This is a good question, and the answer may surprise you.

Humans have a keen sense of smell. Scientists know that when we are hungry, our bodies boost the performance of our sense of smell in order to improve our chances of finding food (1). This is a survival mechanism. When we are hungry, food smells and tastes amazing, leading to the easy conclusion that if we let ourselves get too hungry, we are very likely to overeat.

Scientific research shows that we prefer sweet smells, and that strongly sweet scents such as chocolate often triggers feelings of hunger and leads to overeating or binge eating, while “neutral” sweet smells actually curbs appetite. A scientific study asked 3,193 overweight people (mostly women) aged 18-64 to inhale a variety of what was considered neutral sweet smells: banana, green apple, vanilla, and peppermint, three times in each nostril whenever they were hungry. After six months, the participants lost an average of five pounds per month (2).

How scent impacts your ability to lose weight

Diffusing the right essential oils can assist with weight loss.
Diffusing the right essential oils can help curb appetite, and assist you to lose weight.

It makes sense that smell plays a large part in our hunger cues. If humans’ olfactory systems become enhanced when hungry, it is reasonable to believe that suppressing smell may decrease appetite.

In consideration of essential oils, inhalation is the single most effective way to receive their benefits. When aromas reach the olfactory bulb, they not only trigger the limbic system (emotional center), it triggers your hypothalamus, too. The hypothalamus is the portion of your brain that is connected to satiety. Odor molecules actually inform your brain that you have eaten enough and you are full. You see, it is not only our stomach that dictates our hunger!

Which essential oils are most effective for weight loss?

Given the impact of scent on cravings, specific essential oils can be used in an inhaler to curb our food hankerings. We know based on the above study that certain smells work better than others; but remember, we are not all the same, so personal experimentation may be in order. One thing is for sure: The aromas of essential oils can definitely play a role in weight loss through curbing cravings.

For this cause, Plant Therapy’s team of Certified Aromatherapists created Munchy Stop Synergy (reformulated in late 2017). We designed this blend to help manage hunger cravings, promote healthy eating habits, and help reduce the desire to snack between meals.

Munchy Stop blends the 100% pure, undiluted essential oils of Copaiba, Grapefruit Pink, Tumeric CO2, Lemon Myrtle, and Yuzu.

Here are 5 more single oils that can help you along your weight loss journey:

Peppermint can boost energy levels, which can help maximize your workouts. Not to mention, its soothing properties can help soothe sore muscles after exercise.

Lemon is also a stimulating oil. It promotes a positive mood, which will keep you in a positive mindset.

Lavender and Bergamot are calming, relaxing oils. Over-stressed people tend to overeat, or eat unhealthily. Naturally, if you can lower your stress level, you can better avoid stress-eating (also known as emotional eating).

Grapefruit Pink, diluted to 1% in a carrier oil, can be applied topically to the abdomen to aid with digestive upset.

  1. Could I use Cedarwood Himalayan or Cedarwood Atlas in place of the Cedarwood Virginian? CV is, of course, the one I don’t have.

  2. Could you apply Munchy Stop topically instead of just inhaling it? Where or what spot would it be most effective to stop cravings?

    1. Alicia, you could apply it, but it more to curb appetite because of the scent, which can curb those cravings.. If applying topically, I might apply to chest or wrist, where I can smell it …

  3. Thank you so very much for the info! I love the smell of green apples, but because of how they are farmed now they have lost so much of their scent. What does Yuzu smell like??

    1. Yuzu is uplifting and citrusy! It is a citrus grown in Japan, the scent kind of like a cross between a Mandarin and Grapefruit. It is a favorite of many of us here at Plant Therapy 🙂

  4. What constituent in lemon myrtle is responsible for curbing appetite? I have myrtle, but not lemon myrtle and I thought I might find a substitute for it. TIA

    1. Sue, thanks for your question! It’s not so much the constituent, but the scent. In studies done, they’ve found that instead of stimulating the appetite, sweet, delicious smells actually help people to eat less! Basically, it fools your brain into thinking you’ve eaten something yummy 🙂 So you could use; Lemon or Grapefruit, or Sweet Orange….

  5. Hi, just want to know if how ,any drops of peppermint, lemon,lavender, bergamot and grapefruit will i use in my 380 ml plant theraphy diffuser, can i also mix all this EO and blend it with carrier oil? And whats the exact amount of EO for 10ml roller? Thanks

    1. Hi, Jullianah! You could start out with 1 drop of each oil (depending on your sensitivity) and go up to 2 drops of each oil. You could also mix these oils in a blend for your roller bottle. A 2-3% total dilution is suggested… That would be would be about 1-2 drops of each oil again, with the rest carrier oil.

  6. If I wanted to make a master blend synergy from the Peppermint, Lemon, Lavender (or Bergamot), and Pink Grapefruit , what amounts of each would you suggest? I would probably make it in a 5 ml bottle to have quick access for diffusing and to refill my inhaler.

    1. Hello Leigh Ann! Honestly, it would depend person to person. I myself would benefit from something more for energy so I would do 3 parts Peppermint, 1 part Lemon, and 1 part Grapefruit Pink. Hope this helps!

  7. This blog was very interesting. I remember reading a study that said people ate 10% less food if they smelled peppermint before eating. Maybe ill try the citrus smells next. 🙂
