Using essential oils for appetite, whether stimulating and suppressing, can be tricky. The same essential oils that can suppress the appetite can also encourage an appetite. This is due to some people having a fast metabolism and others having a slow metabolism. Those with a fast metabolism may find the essential oils to encourage an appetite, rather than suppress it.
It's important to know that there are studies showing essential oils like Grapefruit to be effective when inhaled – but not when consumed as you might see all over social media.
Try inhaling the essential oils when a craving hits or when you feel hungry and take note of how your body responds.
