The elephant yam, also known as the konjac plant, contains glucomannan, a fiber found in the roots or corm. It is a dietary fiber of water-soluble polysaccharides.


Glucomannan treats constipation and provides you with a feeling of fullness by absorbing water in your stomach and intestine. It can also help regulate sugar levels and lower cholesterol levels by reducing sugar and cholesterol absorption from the intestines.


According to a survey, the best weight loss pills & diet supplements of 2020 contained glucomannan, but its weight-loss results are mixed.

In a trial conducted in the United States, 20 obese women (weighing 20% more than their target body weight) were given 3g of glucomannan per day or a placebo for eight weeks.

In a comprehensive evaluation of six randomized controlled trials published in 2015, the authors concluded that eating 1.33g before each meal for 3.99g per day did not significantly lower body weight.

2. Garcinia Cambogia

Malabar tamarind, known as Garcinia cambogia, is a famous fix in weight reduction supplements. Garcinia cambogia is an organic product-bearing tree in Asia, Africa, and the Polynesian islands.

The mash and skin of its organic product contain hydroxy citric corrosive (HCA), a compound that has been proposed to restrain lipogenesis, increment hepatic glycogen union, stifle food consumption, and diminish weight gain.


It builds the degree of serotonin, which is responsible for diminishing appetite levels.


In one meta-examination, scientists investigated four electronic exploration data sets to research the adequacy of natural drugs, including Garcinia cambogia. By and large, it caused a weight reduction of around 3 pounds (1.34 kg).

3. Green Coffee Bean Extract

The coffee plant's seeds (or beans) (Coffea arabica, Coffea canephora, Coffea robusta) are green until broiled. Green coffee beans have more elevated levels of chlorogenic corrosiveness.


Green coffee regulates glucose digestion by lessening glucose retention in the stomach. Also, fat regulation is maintained through this ingredient in weight loss supplements.


Green espresso bean concentrate might assist with bringing down glucose levels and increase the metabolism rate.

3. Caffeine

Caffeine is one of the most famous psychoactive substances around the world. These are caffeine in espresso tea, dull chocolate, and more.

Raspberry ketone is the essential fragrance compound tracked down in red raspberries (Rubus idaeus). It is a food source as a seasoning specialist.

In vitro and creature, studies propose that raspberry ketone could assist with forestalling weight gain by expanding unsaturated fat oxidation, smothering lipid gathering, and repressing pancreatic lipase action.


Raspberry Ketone is known to reduce fat and appetite with increasing metabolism. It is excellent for weight reducers and can be considered a staple food or beverage to improve body functioning.


There are not very many examinations on raspberry ketones in people. In 2013, a review showed raspberry ketones alongside a few different fixings and found an expected 2% increment in weight reduction in more than two months when contrasted and fake treatment.

It's obscure whether these impacts would mean people. More examination is to decide any advantages and dangers.

5. Green Tea Extract

Green tea (Camellia sinensis) is a famous drink drunk with a few implied medical advantages. The dynamic parts of green tea weight reduction are caffeine (see the segment on caffeine above) and catechins, principally epigallocatechin gallate (EGCG), which is a flavonoid.

Green Tea extracts reduce lipogenesis, helping individuals maintain or reduce their weight with effective dieting and exercising—a great addition to the weight loss supplements.


Several human studies have been conducted to investigate the effects of green tea catechins on weight loss and maintenance. Green tea consumption lowered body weight by 0.95 kg more than placebo. Green tea is an effective weight loss, and the effect is minimal and insignificant.

6. Conjugated linoleic acid (CLA)

CLA stands for conjugated linoleic acid, a combination of isomers with conjugated double bonds. The multiple isomeric forms of CLA increase lipolysis and fatty acid oxidation.

In skeletal muscle, while decreasing lipogenesis and boosting apoptosis in adipose tissue. It is beneficial for weight loss.


Conjugated Linoleic Acid reduces lipogenesis, as proved through various sampling and research-based experiments. Having it in weight loss supplements is quite effective for the average user. It also improves the immune functioning of the body.


CLA appears to reduce body fat mass in human research, suggesting that its effects are minor and have uncertain clinical significance. CLA supplementation lowered BMI and total body fat in 35 postmenopausal women with obesity (BMI >30).

7. Bitter Orange Or Synephrine

Citrus aurantium is the botanical name for the bitter orange. This plant's fruit contains p-synephrine and other protoalkaloids. Synephrine alkaloids are alpha-adrenergic agonists that can simulate the actions of epinephrine and norepinephrine.

In a study conducted, participants in all groups lost weight; however, they did not say if the treatment group's mean loss of body weight (1.4 kg) was substantially more significant than the placebo group's (0.9 kg) or the control group's (0.4 kg).

According to a comprehensive evaluation of weight loss trials, the evidence for bitter orange/efficacy synephrine is contradictory and limited.

8. Chitosan

Chitosan is a commercially produced polysaccharide made from the exoskeletons of crustaceans.


It helps people lose weight by binding to dietary fat in the digestive tract and blocking it from being absorbed. Chitosan may also aid in the reduction of cholesterol absorption.


In a short trial, 12 healthy men and 12 healthy women ate the same diet for 12 days (five meals per day with 38 percent of calories coming from fat).

Chitosan capsules consumed before meals (total of 2.5 g/day) raised fecal fat excretion in the men somewhat more than in the control group. The quantity of fat trapped, on the other hand, would result in a reduction of only 1 pound of body fat over around seven months.

9. Capsaicin

Chili peppers have a strong flavor, thanks to capsaicinoids. Capsaicin is one of the most prevalent and well-researched capsaicinoids.

Capsaicin has been shown to entail anti-obesity actions by increasing energy expenditure, metabolism rate, lipid oxidation, decreasing appetite, and attenuating postprandial insulin response.

According to the research, capsaicin may induce fullness by generating gastrointestinal discomfort (e.g., pain, burning, and bloating, which may lower the longing to eat) rather than releasing hormones.


Capsaicin is known for augmentation in lipid oxidation and energy expenditure. It also increases your metabolism rate at which you can store energy and burn fat. Capsaicin also lowers the appetite levels to eat less than you usually would.


A 12-week clinical trial in 77 overweight adults matched 2 mg/day and 4 mg/day supplements.

Participants who took 4 mg per day of capsaicinoids consumed 252 fewer calories each day than those who took a placebo and 140 fewer calories each day than those who took 2 mg per day of capsaicinoids.

On the other hand, the calorie decreases did not disturb the body weight after 6 or 12 weeks.

10. Chromium Picolinate

Chromium is a mineral (trace element) that is difficult to absorb, and it is available in hexavalent and trivalent forms. Pigments, dyes, polymers, and inks all utilize hexavalent. Many people who do not eat a healthy diet suffer from a deficiency.


A great addition to weight loss supplements, Chromium Picolinate reduces food cravings and fat. It's best to take the supplement in the mornings as this compound interferes with sleep.


In research, chromium picolinate doses of up to 1,000 g/day were employed. Overall, this study demonstrated that taking chromium picolinate for 12 to 16 weeks resulted in limited weight loss (2.4 pounds or 1.1 kg) in overweight or obese people.

11. Carnitine

Carnitine is found in various plant foods and products such as meat, milk, poultry, and dairy. Humans produce it by combining amino acids.


It is present in almost every cell in the body, carrying fatty acids into the mitochondria and works as a catalyst for fatty acid beta-oxidation.


Carnitine with orlistat (360 mg per day for one year) significantly enhanced weight reduction in 258 people with type 2 diabetes. However, 94 overweight individuals with type-2 diabetes did not affect weight loss.

The findings of nine clinical supplementation studies that measured weight reduction in adults were merged in a review and meta-analysis published in 2016. Participants in the trial dropped 1.33 kg more weight than those who got it controlled.
