How Do Fat Burning Supplements Work?
No two fat burners work the same way. That said, many supplements have overlapping similarities. Arguably the most common mechanism is diet-induced thermogenesis.
Thermogenesis comes from the Greek words "thermos," meaning heat, and "genesis," meaning birth or creation. The process involves increasing energy production through a higher metabolic rate. One of the notable side effects is a higher internal body temperature.
Thermogenic fat burners target carbohydrates for energy first, hindering high-calorie substances from turning into fat stores or entering the bloodstream. Once thermogenesis metabolizes available carbohydrates, it moves to fats. Once your body begins using fat for energy, you'll start seeing weight loss.
According to a 2004 analysis from Nutrition and Metabolism, diet-induced thermogenic fat burners increase energy expenditure by 5% to 15%. As long as you maintain the same caloric intake and exercise levels, you can convert that energy expenditure into fat loss. The bottom line is that thermogenesis is a powerful and natural way to get rid of unwanted fat.
Health Benefits of Taking a Natural Fat Burner Supplement
Weight loss can be exhausting, especially if you hit the gym regularly. Energy boosters, like caffeine, return some pep in your step. The ingredient ensures that you don't suffer from fatigue during your workouts or a lack of motivation.
Reduced Body Fat
While fat burners don't directly metabolize fats, they influence critical bodily functions that enable weight loss. For example, thermogenic supplements raise your internal body temperature. Your body breaks down fat as a response to get rid of heat. As a result, the thermogenic fat burner indirectly transforms you into a slimmer and trimmer version of yourself.
Look for focus enhancers if you want the best results on your weight loss journey. Supplements that improve concentration give you the extra strength needed to get daily exercise and say no to desserts. They can also lift your spirits if you're feeling down.
We all deal with hunger when trying to lose weight. Organic fat burners suppress appetite, so you don't feel hungry all day. For instance, green tea coaxes the body into producing more leptin, a hormone that signals to the brain that you're full.
Your metabolism involves all the chemical reactions in the body, including digestion, fat storage, and energy usage. When you search for the best fat burner, look for supplements that can raise your metabolic rate. The boost allows you to burn more calories and gradually see weight disappear.
Natural Fat-Burner Ingredients Found in Weight Loss Pills
Green Tea Extract
Green tea extract contains the antioxidant epigallocatechin gallate, which amplifies short-term fat burning. The tea also influences norepinephrine production, a hormone that allows people to burn fat. You can start losing weight by consuming the extract or drinking green tea.
Green Coffee Bean Extract
Multiple studies tout green coffee bean extract as an ideal weight loss supplement. The presence of caffeine and chlorogenic acid helps you control your appetite, regulate blood sugar levels, and lower blood pressure. Research from Gastroenterology Research and Practice found that it’s beans can help consumers lose 5.4 pounds or more. Don't roast your coffee beans, though; otherwise, you'll diminish the concentration.
L-carnitine is an amino acid that transports fatty acids into the mitochondria, where the cell can use it for energy. The essential nutrient also plays a central role in anti-oxidation and disease prevention. Studies in animals and humans suggest that it may assist in weight loss.
Raspberry ketones are the compound that makes raspberries smell like raspberries. Some weight loss pills contain a synthetic version that increases adiponectin in the body, a hormone that researchers believe aids weight loss. Studies on rats suggest that the ingredient also makes it easier for the body to metabolize fat.
Black Pepper Extract
Black pepper extract provides a natural way to combat obesity-related diseases. The compound mirrors Grains of Paradise—Aframomum melegueta, a plant in the ginger family similar to cardamom—in its ability to inhibit fat cell proliferation. That means that new fat cells can't readily form and contribute to weight gain. Black pepper extract also has an extensive history of treating diarrhea and cholera in Asia.
Garcinia cambogia comes from the Malabar tamarind, a small pumpkin-like fruit found in Southeast Asia, Africa, and India. The ingredient contains fat blockers, notably hydroxycitric acid (HCA), which prevents the body from creating fat-producing enzymes. Garcinia cambogia also increases serotonin production, which researchers say reduces cravings.
Caffeine is the most widely consumed metabolism-booster in the world. A daily dose can raise your metabolism by 3% to 11% and elevate fat-burning as much as 29%. Too much caffeine can cause short-term side effects, like irritability, diarrhea, and insomnia.
Cayenne Pepper Seeds
Cayenne pepper seeds act as natural thermogenic capsules. The pepper can raise your internal body temperature by a few degrees. Your body will try to dissipate the heat, and in the process, metabolize fat cells. Researchers believe that cayenne pepper seeds can help burn up to 50 extra calories per day.
Try supplements containing chlorogenic acid if you want to lose weight and get your blood sugar levels under control. The compound slows carbohydrate absorption, limiting the flow of glucose into the digestive tract. The stifling mechanism prevents weight gain while mitigating cholesterol and other obesity-related health issues.
Conjugated Linoleic Acid
Conjugated linoleic acid (CLA) is a trans fat found in everyday foods like meat, milk, and butter. The compound plays a vital role in increasing metabolism and fat breakdown and may improve digestive health. While researchers don't entirely understand CLA, some believe it can have damaging side effects over the long-term.
Factors to Consider Before Buying Fat-Burner Supplements
Clinically Dosed Ingredients
"Clinically dosed" are two small-but-important words to look for while researching your fat burners. Clinically tested means that researchers have determined the optimal amount of each ingredient for the desired medical purpose. If your fat burners don't have scientific research backing the dosage, it's impossible to know if the weight loss supplements will be sufficient.
Stimulant or Non-Stimulant?
Amp up your fat-burning potential with a stimulant-laden supplement. These energy boosters provide the pep you need to stay on top of your gym sessions and daily routine. Stimulants can also help you lose excess weight because some substances, like caffeine, double as appetite suppressants.
Stimulants aren't for everyone, though. If you get jittery after a cup of coffee, you should look for an alternative. For example, fat burners like Leanbean enable consistent weight loss without side effects from over-stimulation.
The perfect body is priceless. Well, that's until you factor in the monthly price tag for fat burners. Most supplements cost around $50 per month, though the cost varies based on the brand and quality. Make sure to look for multi-buy discounts so that you can save money on bulk purchases.
Number of Servings in a Bottle
It's hard to go wrong with fat burners that contain 30 to 60 pills per month. The daily tablet provides a simple and straightforward way to bolster your weight loss regimen. Some fat burners require taking tablets three or four times a day, which can feel overwhelming if you're not detail-oriented. In those situations, set an alarm to remind you to take your fat burners throughout the back.
It might take some time for you to find the best fat burner. That may entail trying more than one product until you find something that delivers the results you want without side effects. Give yourself peace of mind during these initial stages by shopping with companies that offer money-back guarantees. That way, you can get a complete refund if it's not right for you.
Things to Avoid When Choosing Fat-Burning Pills
Aggressive Marketing Tactics
You should select the best thermogenic fat burner, not the other way around. Companies that aggressively push their products deserve a healthy dose of scrutiny. Upfront marketing tactics often suggest that the manufacturer is trying to compensate for a shortcoming elsewhere.
Here's the bottom line: you should pick the right fat burner for your needs and health. The thing is that your needs are unique. You should find a product that fits within your diet, budget, and schedule. When it comes to losing weight, don’t let pushy marketers tell you the right way for you to lose weight or what weight loss program or exercise program you should do.
It's impossible to overstate the importance of knowing what goes into your body. While proprietary formulas (that is, recipes kept secret) may appear state-of-the-art, they prevent consumers from understanding the ingredients. Make sure your manufacturer of choice provides a complete list of ingredients, with their amounts, on its website and the label.
Be leery of any manufacturers that are less-than-forthcoming about what's inside their weight loss supplements. You shouldn't risk harmful side effects or an allergic reaction for the sake of weight loss. Your number-one priority should be finding a fat burner that works with your body, not against it.
Too Many Stimulants
Many fat burners contain stimulants to help you achieve the best results. That's because stimulants break down fat and move the byproducts into the bloodstream for energy. If you don't have a lot of available energy, you may feel tired or sluggish.
Stimulants provide the boost you need to lose weight, but the bottom line is that you could get too much of a good thing. An excessive amount can leave you with a host of side effects, including nervousness, restlessness, insomnia, and jitters. Reading the ingredients will help you lose weight without unwanted complications.
How to Get the Most Out of Fat Burners
Diet and exercise serve as the backbone of effective weight loss. A healthy diet can prevent long-term diseases, such as obesity, cancer, and type II diabetes, while exercising allows you to build strength and stamina. A fat burner makes diet and exercise more sustainable, even if you have lofty weight-loss goals.
For instance, you might go for a long run every day. When you get home, you find yourself famished and craving a sugary treat. Indulging in an ice cream cone or donut would instantly negate your calorie-burning hard work from running.
Weight loss supplements like Leanbean work by suppressing appetite. They create the illusion that you're full, even when you're not. That way, you can go for your long run and avoid overeating afterward, reaping all the benefits of your substantial caloric burn.

Make sure to read the label before you commit to a weight loss supplement. Some options, such as Instant Knockout, contain stimulants such as caffeine and ginseng. If you're sensitive to stimulants, consider a stimulant-free option to avoid unwanted side effects.
Who Should Use Fat Loss Pills?
Millions of men and women struggle to lose weight, even with a healthy diet and exercise. Today, you don't have to struggle any longer. Fat burners provide effective support and performance to slim down to your ideal body weight.
