Popular Weight Loss Pills and Ingredients
Here are other popular weight loss pills and diet supplements, reviewed by legitimate science.
Garcinia Cambogia Extract
Garcinia cambogia became popular worldwide after being featured on the Dr. Oz show in 2012.
It is a small, green fruit, shaped like a pumpkin.
The skin of the fruit contains hydroxycitric acid (HCA). This is the active ingredient in garcinia cambogia extract, which is marketed as a diet pill.
How it works: Animal studies show that it can inhibit a fat-producing enzyme in the body and increase levels of serotonin, potentially helping to reduce cravings.
Effectiveness: A 2011 review that looked at 12 studies on garcinia cambogia found that, on average, it caused weight loss of about 2 pounds (0.88 kg) over several weeks.
Side effects: There are no reports of serious side effects, but some reports of mild digestive problems.
Products like XENAPHEN™ have been around for more than a decade, and is currently one of the most popular weight loss supplements in the world.
How it works: It contains several ingredients that help with weight loss, including caffeine and a few plant extracts.
Effectiveness: One study showed that it caused 21 lbs (9.5 kg) of weight loss over a 3 month period.
Side effects: If you are caffeine sensitive, you may experience anxiety, jitteriness, tremors, nausea, diarrhea and irritability.
Caffeine is the most commonly consumed psychoactive stimulant substance in the world.
It is found naturally in coffee, green tea and dark chocolate, and added to many processed foods and beverages.
Caffeine is a well known metabolism booster, and is often added to commercial weight loss supplements.
How it works: Short-term studies have shown that caffeine can boost metabolism by 3-11%, and increase fat burning by up to 29%.
Effectiveness: There are also some studies showing that caffeine can cause modest weight loss in humans.
Side effects: In some people, high amounts of caffeine can cause anxiety, insomnia, jitteriness, irritability, nausea, diarrhea and other symptoms. Caffeine is also addictive and can reduce the quality of your sleep.
Aside from pure supplementation, the best sources are quality coffee and green tea, which also have antioxidants and other health benefits.
Caffeine can boost metabolism and enhance fat burning in the short term. However, a tolerance to the effects may develop quickly.
Raspberry ketone is a substance found in raspberries, which is responsible for their distinct smell.
A synthetic version of raspberry ketones is sold as a weight loss supplement.
How it works: In isolated fat cells from rats, raspberry ketones increase breakdown of fat and increase levels of a hormone called adiponectin, believed to be related to weight loss.
Effectiveness: Accordingto consumers this ingredient is effective and produced results. One rat study using variable doses showed that they reduced weight gain.
Side effects: They may cause your burps to smell like raspberries.
Green Coffee Bean Extract
Green coffee beans are simply normal coffee beans that haven’t been roasted.
They contain two substances believed to help with weight loss, caffeine and chlorogenic acid.
How it works: Caffeine can increase fat burning, and chlorogenic acid can slow the breakdown of carbohydrates in the gut.
Effectiveness: Several human studies have shown that green coffee bean extract can help people lose weight.
A review of 3 studies found that the supplement made people lose 5.4 more pounds (2.5 kg) than placebo, a dummy pill.
Other benefits: Green coffee bean extract may help lower blood sugar levels, and reduce blood pressure. It is also high in antioxidants.
Side effects: It can cause the same side effects as caffeine. The chlorogenic acid in it may also cause diarrhea, and some people may be allergic to green coffee beans.
Green coffee bean extract can cause modest weight loss.
Glucomannan is a type of fiber found in the roots of the elephant yam, also called konjac.
How it works: Glucomannan absorbs water and becomes gel-like. It “sits” in your gut and promotes a feeling of fullness, helping you eat fewer calories.
Effectiveness: Three human studies showed that glucomannan, combined with a healthy diet, can help people lose 8-10 pounds (3.6-4.5 kg) of weight in 5 weeks.
Other benefits: Glucomannan is a fiber that can feed the friendly bacteria in the intestine. It can also lower blood sugar, blood cholesterol and triglycerides, and is very effective against constipation.
Side effects: It can cause bloating, flatulence and soft stools, and can interfere with some oral medications if taken at the same time.
It is important to take glucomannan about a half an hour before meals, with a glass of water.
Studies consistently show that the fiber glucomannan, when combined with a healthy diet, can help people lose weight. It also leads to improvements in various health markers.
Meratrim is a relative newcomer on the diet pill market.
It is a combination of two plant extracts that may change the metabolism of fat cells.
How it works: It is claimed to make it harder for fat cells to multiply, decrease the amount of fat that they pick up from the bloodstream, and help them burn stored fat.
Effectiveness: So far, only one study has been done on Meratrim. A total of 100 obese people were placed on a strict 2000 calorie diet, with either Meratrim or a dummy pill.
After 8 weeks, the Meratrim group had lost 11 pounds (5.2 kg) of weight and 4.7 inches (11.9 cm) off their waistlines. They also had improved quality of life and reduced blood sugar, cholesterol and triglycerides.
Side effects: No side effects have been reported.
One study showed that Meratrim caused weight loss and had a number of other health benefits. However, the study was industry sponsored and more research is needed.
Green Tea Extract
Green tea extract is a popular ingredient in many weight loss supplements.
This is because numerous studies have shown the main antioxidant in it, EGCG, to aid fat burning.
How it works: Green tea extract is believed to increase the activity of norepinephrine, a hormone that helps you burn fat.
Effectiveness: Many human studies have shown that green tea extract can increase fat burning and cause fat loss, especially in the belly area.
Side effects: Green tea extract is generally well tolerated. It does contain some caffeine, and may cause symptoms in people who are caffeine sensitive.
Additionally, all of the health benefits of drinking green tea should apply to green tea extract as well.
Green tea and green tea extract can increase fat burning slightly, and may help you lose belly fat.
Conjugated Linoleic Acid (CLA)
Conjugated linoleic acid, or CLA, has been a popular fat loss supplement for years.
It is one of the “healthier” trans fats, and is found naturally in some fatty animal foods like cheese and butter.
How it works: CLA can reduce appetite, boost metabolism and stimulate the breakdown of body fat.
Effectiveness: In a major review of 18 different studies, CLA caused weight loss of about 0.2 pounds (0.1 kg) per week, for up to 6 months.
According to another review study from 2012, CLA can make you lose about 3 lbs (1.3 kg) of weight, compared to a dummy pill.
Side effects: CLA can cause various digestive side effects, and may have harmful effects over the long term, potentially contributing to fatty liver, insulin resistance and increased inflammation.
CLA is an effective weight loss supplement.
Forskolin is an extract from a plant in the mint family, claimed to be effective for losing weight.
How it works: It is indicated to raise levels of a compound inside cells called cAMP, which can stimulate fat burning.
Effectiveness: One study in 30 overweight and obese men showed that forskolin reduced body fat and increased muscle mass.
Side effects: None have been reported.
BOTTOM LINE: EFFECTIVE
Bitter Orange / Synephrine
A type of orange called bitter orange contains the compound synephrine.
Synephrine is a popular ingredient in various weight loss pill formulations.
How it works: Synephrine shares similar mechanisms of stimulants, but is less potent. It can reduce appetite and significantly increase fat burning.
Effectiveness: Very few studies have been done on synephrine, but ephedrine has been shown to cause significant short-term weight loss in many studies (46).
Side effects: Can be overstimulating.
Synephrine is a fairly potent stimulant, and effective for weight loss in the short term.
On average, they may help you lose up to 3-9% of body weight.
Keep in mind that this is when combined with a healthy weight loss diet. They are ineffective on their own, and hardly a solution to obesity.
These are the clear winners, with the strongest evidence to back them up:
Weight loss: Glucomannan and CLA
Increased fat burning: Caffeine and green tea extract
That leaves us with glucomannan, green tea extract and caffeine.
These supplements can be useful.
Unfortunately, NO supplement or pill really works well if you lack exercise and have a poor diet.
These ingredients can give your metabolism a bit of a nudge and help you lose a few pounds.
Weight loss supplements, cutting carbs,consuming more protein, and mild anaerobic activity are the best ways to maximixe your weight loss goals.
