Various herbs and plants possess the potential to assist in weight loss by curbing appetite. They achieve this by enhancing the sensation of fullness, decelerating gastric emptying, obstructing nutrient absorption, or modulating hunger-related hormones.

This article delves into a selection of natural herbs and plants recognized for their capacity to reduce food intake by suppressing appetite, amplifying the feeling of satiety, or diminishing cravings for food.

Below is a list of 10 natural appetite suppressants that could aid in your weight loss journey.

1. Fenugreek (Methi)

Fenugreek, known as Methi in India, is a remarkable herb belonging to the legume family. Among its various parts, the seeds are predominantly utilized, especially after being dried and ground into a fine powder, which is popular in many cuisines around the world. This herb is rich in both soluble and insoluble fiber, which can significantly enhance the sensation of fullness, potentially leading to a reduction in overall food intake. In a study conducted in Korea, nine overweight females were given fennel, fenugreek, or a placebo tea prior to a buffet meal.

The results revealed that participants who consumed fenugreek tea experienced:

• a marked decrease in hunger
• less desire to consume food
• a heightened sense of satiety

Nevertheless, it is important to note that there were no significant differences in the total quantity of food consumed among the groups. Furthermore, this study was limited in scope, and it remains uncertain whether the appetite-suppressing effects were primarily due to the fiber content or other beneficial compounds present in fenugreek. Thus, further investigation is essential to validate the appetite-suppressing properties of fenugreek.

2. Glucomannan and Other Viscous Fibers

Dietary fibers, notably glucomannan (also known as konjac in India), have shown potential in managing appetite and promoting weight loss. This particular fiber is derived from the starchy root of the konjac plant, which is commonly utilized in the creation of noodles and various food products across different cultures. A comprehensive review conducted in 2020 found that the consumption of viscous fibers, including glucomannan, can lead to a modest yet significant reduction in body weight and other fat-related metrics. This effect is particularly pronounced among individuals with elevated body weight, diabetes, or metabolic syndrome, making it a valuable addition to their dietary regimen.

Safety and Recommended Dosage

Research indicates that a daily intake of up to 15.1 grams of glucomannan is generally considered safe over several weeks. However, it is crucial to note that glucomannan tablets can present a choking risk if not taken appropriately. Some individuals may experience side effects such as loose stools, flatulence, diarrhea, constipation, or abdominal discomfort. Despite these potential adverse effects, glucomannan remains a beneficial type of fiber that aids in appetite suppression by forming a viscous gel that slows the absorption of fats and carbohydrates.

3. Gymnema sylvestre

Gymnema sylvestre, a revered herb traditionally utilized in India for its antidiabetic properties, is also gaining attention for its potential anti-obesity effects. Recent research from 2012 indicates that this remarkable herb may possess beneficial properties that aid in managing blood lipids and various factors commonly elevated in individuals struggling with obesity.

In this particular study, rats subjected to a high-fat diet followed by administration of Gymnema sylvestre extract over a span of 28 days exhibited notable reductions in cholesterol levels and body mass index (BMI). These findings point towards its promising role in weight management. Nonetheless, further research is essential to ascertain the safety and efficacy of Gymnema sylvestre for humans aiming to control weight and suppress appetite.

Overall, Gymnema sylvestre is an herb that may contribute positively to efforts in reducing obesity.

4. Griffonia simplicifolia (5-HTP)

Griffonia simplicifolia is a unique plant renowned for its high content of 5-hydroxytryptophan (5-HTP), a compound that plays a crucial role in the synthesis of serotonin in the brain. An increase in serotonin levels is believed to assist in reducing appetite, as indicated by various studies.

Some earlier, albeit limited, research suggests that 5-HTP may aid individuals in their battle against obesity by promoting a sense of satiety. Nonetheless, it is important to note that using 5-HTP supplements could elevate the risk of serotonin syndrome, a potentially serious condition that can arise from excessive serotonin levels. Therefore, it is always advisable to seek guidance from a healthcare professional before beginning any supplement regimen.

Griffonia simplicifolia is indeed a plant abundant in 5-HTP, which is converted into serotonin within the brain, contributing to reduced feelings of hunger.

5. Caralluma fimbriata

Caralluma fimbriata is a remarkable herb known for its potential to suppress appetite and aid in the management of obesity. In a clinical trial involving 83 overweight individuals, participants consumed either a supplement containing Caralluma fimbriata extract or a placebo over a span of 16 weeks. By the conclusion of the study, those who took the extract experienced a notable reduction in calorie intake and waist circumference. Interestingly, while the participants on the extract maintained their weight, those in the placebo group actually gained weight.

Another study indicated that while Caralluma fimbriata extract could effectively reduce waist circumference, it did not significantly influence overall body weight or Body Mass Index (BMI). Some noted side effects of this herb may include constipation, diarrhea, nausea, and skin rashes. Nevertheless, incorporating Caralluma fimbriata into a regimen that includes exercise and a calorie-controlled diet may enhance weight loss efforts.

6. Green Tea Extract

Green tea extract is recognized for its potential efficacy in promoting weight loss along with various other health benefits. This remarkable beverage is enriched with two key compounds that play a significant role in weight management: caffeine and catechins. Caffeine acts as a natural stimulant that enhances the body's ability to burn fat while also curbing appetite. On the other hand, green tea catechins, especially epigallocatechin gallate (EGCG), are known to accelerate metabolism and facilitate fat reduction.

Research indicates that consuming green tea with EGCG levels ranging from 100 to 460 milligrams (mg) daily over a span of 12 weeks can assist in diminishing body weight and fat mass. Furthermore, the inclusion of caffeine at doses between 80 and 300 mg per day can amplify these effects, making it a potent ally in weight loss efforts.

Another study highlighted the advantages of beverages that combine soluble fiber, EGCG, and caffeine, as they may reduce the likelihood of overeating during subsequent meals. This suggests that green tea extract, due to its caffeine and catechin content, may not only invigorate metabolism and facilitate fat burning but also support weight loss by decreasing appetite and curtailing food intake when combined with other beneficial ingredients.

7. Conjugated Linoleic Acid

Conjugated linoleic acid (CLA) is a specific type of fat found in various animal fats and is also available as dietary supplements. Some researchers believe that CLA supplements could potentially assist in enhancing body composition, as well as aiding in the reduction of body fat and obesity; however, further research is essential to confirm these claims.

This naturally-occurring trans fat may play a role in weight loss by altering the way your body processes fat. Its effects are still being studied, and while there is some optimism regarding its benefits, more extensive studies are necessary to fully understand its impact on health and weight management.

8. Garcinia Cambogia

Garcinia cambogia, derived from a fruit that shares its name, is also known in some regions as Garcinia gummi-gutta. This intriguing fruit is particularly recognized for its peel, which is rich in hydroxycitric acid (HCA). This compound is thought to exhibit potential weight loss benefits, making it a subject of interest in dietary discussions.

A comprehensive review of eight clinical trials involving a total of 530 participants indicated that supplementation with Garcinia could lead to reductions in various health metrics, including:

• overall body weight
• fat mass percentage
• circumference around the waist

Nonetheless, further studies are essential to thoroughly validate the safety and efficacy of Garcinia HCA supplements in the context of weight management. It's worth noting that Garcinia cambogia is a source of hydroxycitric acid (HCA), which has demonstrated the ability to elevate serotonin levels in the body. This increase in serotonin may contribute to enhanced feelings of fullness. However, it is important to consider that some research indicates there may not be significant effects linked to this supplement.

9. Yerba Mate

Yerba mate, a plant indigenous to South America, is celebrated for its remarkable energy-boosting qualities. This herbal beverage is gaining popularity across the globe, thanks to its numerous health benefits. Recent studies suggest that consuming capsules containing a total of 3 g of yerba mate daily over a span of 12 weeks could potentially aid in reducing body fat and enhancing the waist-hip ratio in individuals dealing with obesity.

Additionally, research involving 12 healthy women has shown that ingesting 2 g of yerba mate prior to engaging in a 30-minute cycling session led to a decrease in appetite while simultaneously increasing metabolism, mental focus, and overall energy levels. This potent plant is not only beneficial for physical performance but also appears to be safe for consumption, as it does not seem to cause any severe adverse effects. However, it is crucial to note that consuming yerba mate at extremely high temperatures or reusing the same leaves may heighten the risk of esophageal and other forms of cancer.

10. Coffee

Research indicates that the caffeine found in coffee can aid in weight management through various mechanisms:

• enhancing calorie expenditure
• facilitating fat decomposition
• curbing hunger

Interestingly, consuming caffeine prior to a meal may affect gastric emptying rates, appetite-regulating hormones, and overall feelings of satiety. This can lead to reduced food intake.

However, it is essential to be mindful that excessive caffeine consumption may elevate blood pressure in certain individuals. The caffeine present in coffee is known to suppress appetite, prolong gastric emptying, and impact hunger-related hormones, which can collectively support a decrease in caloric intake. Additionally, caffeine has the potential to boost fat oxidation and assist in weight reduction.

The Bottom Line

Various herbs and plants can potentially facilitate weight loss in a natural way.

These herbs may work through several mechanisms, including:

• curbing appetite
• enhancing feelings of satiety
• delaying gastric emptying
• preventing nutrient absorption
• modulating appetite-related hormones
• accelerating energy expenditure
• promoting fat breakdown

The strategies mentioned above can serve as a complementary approach to achieving weight loss, especially when combined with balanced dietary choices and regular physical activity.
