Does Maca Suppress Appetite?

Maca may influence appetite through hormonal regulation and energy metabolism, but conclusive evidence is lacking.

Maca, a plant native to the Peruvian Andes, has been used for centuries for its nutritional and medicinal properties. Known as “Peruvian ginseng”, it is rich in essential nutrients and bioactive compounds. This article explores whether maca has appetite-suppressing properties based on scientific literature and anecdotal evidence.

Nutritional Profile and Traditional Uses

Maca, scientifically known as Lepidium meyenii, has been a dietary staple and natural remedy for native Peruvians. It is consumed in various forms, including dried powder, capsules, and extracts. The plant is known for its potential benefits in enhancing energy, fertility, libido, and overall vitality, particularly in aging populations. According to a study, maca is rich in essential nutrients like fiber, amino acids, vitamins, minerals, and bioactive compounds such as macamides, macaridine, alkaloids, and glucosinolates.

Traditionally, maca has been used to improve energy levels and stamina. It is often referred to as an adaptogen, helping the body adapt to stressors. This adaptogenic property is one reason why people believe maca might help with appetite suppression. However, the scientific evidence supporting this claim is still under investigation.

Scientific Evidence on Appetite Suppression

Hormonal Regulation and Satiety

One mechanism through which maca may influence appetite is by regulating hormones. A study on postmenopausal women found that maca consumption reduced body weight by regulating certain hormones, including adrenocorticotropic hormone (ACTH), which is associated with weight gain. The reduction in ACTH levels may contribute to decreased appetite and subsequent weight loss, according to a study.

Energy Metabolism and Physical Activity

Maca is also known to enhance energy metabolism, which can indirectly affect appetite. By providing sustained energy, maca may reduce the need for frequent snacking or overeating. A study involving cyclists found that maca consumption significantly improved physical performance, suggesting that it provides energy for physical activities without causing fatigue. This increased energy expenditure could potentially lead to a natural reduction in appetite, as noted in the same study.

User Reviews and Anecdotal Evidence

Anecdotal evidence from user reviews suggests that maca may have appetite-suppressing effects. For instance, one user reported that after taking maca for hormone balance and energy, they experienced better moods, increased muscle mass, and a more regular menstrual cycle. They also noted an increased appetite, which they attributed to the muscle gain and overall improvement in health. However, this increased appetite was seen as a positive outcome, as the user was previously underweight, according to WebMD.

Clinical Studies and Observations

Clinical studies on maca have primarily focused on its effects on sexual health, energy metabolism, and overall well-being. A study involving the administration of maca capsules to postmenopausal women showed improvements in sexual function and mood but did not specifically address appetite suppression. Another study on the effects of maca on physical performance in male athletes reported increased endurance and energy levels but did not mention any changes in appetite, according to Frontiers in Pharmacology.

Potential Mechanisms of Action

The potential appetite-suppressing effects of maca may be attributed to its adaptogenic properties, which help the body manage stress and maintain hormonal balance. By reducing stress and improving mood, maca may indirectly influence appetite regulation. Additionally, the presence of bioactive compounds such as macamides and glucosinolates may play a role in modulating metabolic processes and energy expenditure, further contributing to appetite control.

Key Takeaways

  • Maca is rich in essential nutrients.
  • It may influence appetite through hormonal regulation.
  • Enhanced energy metabolism could reduce the need for frequent snacking.
  • Anecdotal evidence suggests mixed effects on appetite.
  • Clinical studies focus more on sexual health and energy levels.


Maca shows promise in various health aspects, but its role in appetite suppression remains to be fully elucidated. While some studies and anecdotal reports suggest that maca may influence hormonal regulation and energy metabolism, leading to potential changes in appetite, more research is needed to establish a direct link. The current literature primarily focuses on maca’s benefits for sexual health, energy levels, and overall well-being, with limited data on its effects on appetite suppression.
