doTERRA Slim & Sassy Supplements Facts

doTERRA Slim & Sassy Supplements Facts

Grapefruit Peel Oil

: There is animal research supporting the use of grapefruit oil for reducing appetite and boosting metabolism.

A study in The Scientific Journal Neuroscience Letters found that when rats smelled grapefruit oil three times per week for 15 minutes at a time, they reduced their food intake and therefore lost weight.

A review of the research with grapefruit oil also concluded that when animals smell this oil, it increases the activity of nerves in the sympathetic nervous system, leading to an increase in metabolism and fat burn.

Lemon Peel Oil

: Animal research also suggests that lemon essential oil may be helpful for weight management.

According to a review of studies with this essential oil, it can reduce weight gain and body fat accumulation among mice given a high-fat diet.

Peppermint Oil

: Peppermint essential oil seems to boost energy levels, which can help you to work out harder while trying to meet your weight loss goals.

A 2013 study in The Journal of the International Society of Sports Nutrition found that after men supplemented with peppermint oil for 10 days, they were able to exercise for longer before becoming exhausted, and they worked harder during their workout.

Ginger Oil

: A major health benefit of ginger root is its ability to support healthy digestion. Bloating, nausea, and indigestion have all been treated with it for a long time. According to our peer-reviewed published article on Smooth Move Tea, ginger root aids in promoting the production of digestive enzymes, which enhance the breakdown and absorption of nutrients in the body.

A review of multiple studies that evaluated the effects of ginger on weight loss found that it resulted in reduced body weight as well as a lower waist-to-hip ratio, suggesting that it produced belly fat loss.

Ginger may also reduce appetite, as a study in the journal Metabolism found that it increased feelings of fullness when consumed with breakfast.

Cinnamon Oil

: Cinnamon may be effective for weight loss because it has been found to reduce blood sugar levels after a meal and slow the emptying of the stomach.

By stabilizing blood sugar levels, cinnamon can prevent you from giving in to cravings that are the result of blood sugar fluctuations.
