Fenugreek is a common household spice derived from Trigonella foenum-graecum, a plant belonging to the legume family.
Several studies have found that fenugreek may help control appetite and reduce food intake to support weight loss.
One study in 18 people showed that supplementing with 8 grams of fenugreek fiber daily increased feelings of fullness and reduced hunger and food intake, compared to a control group (1).
Another small study found that taking fenugreek seed extract decreased daily fat intake by 17%, compared to a placebo. This resulted in a lower number of calories consumed over the course of the day (2).
Summary Fenugreek is a spice that has been shown to reduce appetite and food intake to support weight loss.

Ginger is a spice made from the rhizome of the flowering ginger plant, Zingiber officinale.
Often used in folk medicine as a natural remedy for a wide variety of ailments, some research indicates that ginger could aid weight loss as well.
One review of 14 human studies showed that supplementing with ginger significantly decreased both body weight and belly fat (7).
Another review of 27 human, animal and test-tube studies also concluded that ginger may help lower weight by increasing metabolism and fat burning while simultaneously decreasing fat absorption and appetite (8).
Summary Ginger, a spice commonly used in folk medicine, may aid weight loss. Studies show that it may increase metabolism and fat burning, as well as decrease fat absorption and appetite.
Oregano is a perennial herb that belongs to the same plant family as mint, basil, thyme, rosemary and sage.
It contains carvacrol, a powerful compound that may help boost weight loss.
One study in mice on a high-fat diet that either contained carvacrol or not found that those that received carvacrol gained significantly less body weight and body fat than the control group.
Carvacrol supplements were also found to directly impact some of the specific genes and proteins that control fat synthesis in the body (9).
However, research on the effects of oregano and carvacrol on weight loss is still very limited. Human-based studies are lacking in particular.
Summary Oregano is an herb that contains carvacrol. One animal study showed that carvacrol may help decrease weight and fat gain by altering fat synthesis in the body. Human-based research on oregano and weight loss is lacking.
Ginseng is a plant with health-promoting properties that is often considered a staple in traditional Chinese medicine.
It can be categorized into several different types, including Korean, Chinese and American, all of which belong to the same genus of ginseng plants.
Many studies have suggested that this powerful plant could aid weight loss.
One small study found that taking Korean ginseng twice daily for eight weeks resulted in quantifiable reductions in body weight, as well as changes in gut microbiota composition (10).
Similarly, an animal study showed that ginseng combatted obesity by altering fat formation and delaying intestinal fat absorption (11).
However, more high-quality, large-scale studies are needed to examine ginseng’s impact on weight loss in humans.
Summary Ginseng, which is often used in traditional Chinese medicine, may stimulate weight loss, delay fat absorption and modify fat formation.
Caralluma Fimbriata is an herb that is often included in many diet pills.
One 12-week study in 33 people found that participants who took Caralluma Fimbriata had significantly greater decreases in belly fat and body weight, compared to those on a placebo (14).
Summary Caralluma Fimbriata is an herb commonly used in diet pills that may help decrease appetite to stimulate weight loss.
Turmeric is a spice revered for its flavor, vibrant color and potent medicinal properties.
Most of its health benefits are attributed to the presence of curcumin, a chemical that has been studied extensively for its effects on everything from inflammation to weight loss.
Similarly, an animal study found that supplementing mice with curcumin for 12 weeks reduced body weight and body fat by blocking the synthesis of fat (17).
However, keep in mind that these studies use a concentrated amount of curcumin, far greater than the amount present in a typical dose of turmeric.
More research is needed to examine how turmeric itself may impact weight loss.
Summary Turmeric is a spice that contains curcumin, which has been shown to aid weight loss and fat loss in human and animal studies.
Black pepper is a common household spice derived from the dried fruit of Piper nigrum, a flowering vine native to India.
It contains a powerful compound called piperine, which supplies both its pungent flavor and potential weight-lowering effects.
One study found that supplementing with piperine helped reduce body weight in rats on a high-fat diet, even with no changes in food intake (18).
A test-tube study also showed that piperine effectively inhibited fat cell formation (19).
Unfortunately, current research is still limited to test-tube and animal studies.
Further studies are needed to determine how piperine and black pepper may influence weight loss in humans.
Summary Black pepper contains piperine, which has been shown to help decrease body weight and inhibit fat cell formation in test-tube and animal studies. Human research is lacking.
Gymnema sylvestre is an herb that is often used as a natural remedy to help reduce blood sugar levels.
However, some research shows that it may also benefit those looking to lose weight.
It contains a compound called gymnemic acid, which can help reduce the perceived sweetness of foods to ward off sugar cravings (20).
In fact, one study concluded that taking Gymnema sylvestre reduced both appetite and food intake, compared to a control group (21).
A three-week animal study also found that eating this herb helped maintain body weight in rats on a high-fat diet (22).
Summary Gymnema sylvestre is an herb often used to lower blood sugar. Human and animal studies show that it may also aid weight loss by reducing appetite and food intake.
Cinnamon is an aromatic spice made from the inner bark of trees in the Cinnamomum genus.
It’s rich in antioxidants and offers several health benefits. Some studies have even found that cinnamon could increase weight loss.
It’s especially effective in stabilizing blood sugar, which may help reduce appetite and hunger (23).
Cinnamon may also decrease levels of certain digestive enzymes to slow the breakdown of carbohydrates (26).
While these effects could potentially decrease appetite and lead to weight loss, more research is needed to study the effects of cinnamon directly on weight.
Summary Cinnamon is a spice that can decrease blood sugar, which could lead to reduced appetite and hunger.
Green coffee bean extract is commonly found in many weight-loss supplements.
It’s made from coffee beans that haven’t been roasted and is high in chlorogenic acid, which is thought to account for its potential weight-lowering effects.
One study found that consuming green coffee reduced body mass index (BMI) and belly fat in 20 participants, even with no changes in calorie intake (27).
Another review of three studies concluded that green coffee bean extract may decrease body weight by 5.5 pounds (2.5 kg) on average. However, researchers noted that the quality and size of available studies was somewhat limited (28).
Therefore, more high-quality studies are needed to evaluate the effectiveness of green coffee bean on weight loss.

It’s used worldwide in both cooking and baking but may also support weight loss.
Similarly, another animal study showed that black cardamom in particular was effective in reducing both belly fat and total body fat in rats on a high-fat diet (32).
Unfortunately, most research on cardamom’s weight loss potential is limited to animal studies.
Cardamom’s influence on weight loss in humans has yet to be investigated.
Summary Cardamom is a highly prized spice that has been shown to reduce belly and body fat in some animal studies. Human-based research is lacking.
