How Do Thermogenic Fat Burners Work?
Fat Oxidation
You may have heard the terms “fat burning” and “fat oxidation” used interchangeably. The two biological processes represent similar things. When someone talks about burning fat, they’re describing the physiological oxidizing of fat.
The best fat burner supplements magnify this reaction at all three stages of metabolism. Fat burning begins with lipolysis, where an enzyme called lipase strips fatty acids from triglycerides. Fat burners transport the fatty acids to the bloodstream via a protein called serum albumin.
Once these taxi-like cells bring the fatty acids to the mitochondria, oxidation begins. The body converts the material into ATP, which allows cells to complete essential functions. The best fat burners augment this process so that the metabolism process can burn fat and create ATP faster.
Thermogenesis
Thermogenic fat burner supplements include natural ingredients that boost metabolism and burn fat. The process involves raising a person’s body temperature a few degrees. Some of the most popular thermogenic ingredients include green tea, caffeine, garcinia cambogia, and chromium picolinate.
A fat burner supplement works while your body breaks down the food. That’s because an active metabolism causes your body temperature to rise. Thermogenic ingredients in natural fat burners raise the temperature even higher so that you burn more calories.
The same process occurs when you drink lukewarm and cold water. The body needs more energy to heat the cold liquid compared to water at room temperature. Since your body uses more fuel to accommodate the ice water, your body burns more calories, causing more significant fat loss.
Appetite Suppression
If you have an empty stomach, your body needs to signal the brain to eat more. The easiest way to achieve that is with ghrelin, also known as the human hormone. It triggers your body to eat food and explains why ghrelin levels peak before you eat.
However, overeating can offset your weight loss achievements. Thermogenic fat burners like Trimtone and Leanbean work to silence your cravings. Both products contain glucomannan, a dietary fiber ideally suited for suppressing appetite.
Some fat burners use stimulants, such as green tea and caffeine, to tamp down on hunger. While they work well for suppressing appetite, they may leave you feeling jittery and anxious. If you want to avoid potential side effects, consider stimulant-free fat burners like Trimtone and Leanbean.
What to Look for in Top Fat-Burning Supplements
Clean Labels
What ingredients are in belly fat burners? Sometimes, there’s no way of knowing. Manufacturers may hide behind a proprietary label so that they can keep their weight loss supplements’ recipes a secret.
While secrecy has its time and place, it’s not in the supplements industry. No one should take a fat burner only to discover they’re allergic to the ingredients. If a company doesn’t tell you what’s inside its product, you should consider that a red flag.
You can mitigate your risk by looking for thermogenic fat burners with clean labels. These manufacturers display the ingredients on the label and their website. That way, there’s no guessing about what you’re taking when you’re losing weight.
Natural Ingredients
What you put in your body matters. The last thing you want is to consume fillers and artificial ingredients that leave you with brain fog and fatigue. Before you buy a fat burner supplement, double-check that it has wholesome ingredients.
Each of the natural fat burners on this list utilizes 100% natural ingredients. The manufacturers source high-quality products from around the world to ensure that consumers lose weight efficiently. Natural fat burners also have fewer side effects than their prescription counterparts, providing a smoother weight loss journey.
Money-Back Guarantee
How confident is a company that it has the top thermogenic fat burner? You can survey the fine print and uncover the answer. Companies that believe in their products tend to offer money-back guarantees. If you don’t love the results after using these thermogenic fat burner supplements, you can return them for a complete refund.
You should raise an eyebrow at any fat burners without refund policies. It may mean the pills have less-than-stellar ingredients. The company doesn’t want to refund the purchase because it knows people will demand one when they don’t see results. A refund would cut into their bottom line and hurt their business model.
Discounts for Multiple Bottles
The top fat burner supplements cost $50 to $70 per bottle. Savvy customers can avoid paying full price by tapping into the power of multi-buy discounts. Some manufacturers lower the price the more bottles you buy, allowing you to continue your fat-burning process.
For example, a month’s supply may cost $49.99. However, when you buy a two-month supply, you receive an extra bottle of weight loss supplements for free. That translates to $33.33 apiece. Some companies also apply free shipping and other perks, such as a 15-day workout guide when you purchase more than one bottle at a time.
Health Benefits of Taking a Thermogenic Fat Burner
Targets Stubborn Fat
Many men and women experience a plateau during their weight-loss saga. Despite their best efforts, they cannot shed lingering belly fat. In some cases, people even experience weight gain. The best fat burners zero in on stubborn fat, helping to reveal the trim, tone body underneath.
Most fat burners work in one of two ways. First, a fat burner can coax cells into releasing fatty acids into the bloodstream, where the body metabolizes them. This approach enables people to lose weight while maintaining consistent energy levels.
Some weight loss pills halt fat production altogether. These fat burners send a signal to the body, telling it to stop storing fat. Instead, the body excretes the potential fat with other waste.
Prevents Overeating
Most fat burners do an excellent job of accelerating weight loss. However, they can leave you feeling hungrier than usual. That’s because your body wants to replace the burned calories with energy from food.
The best fat burner pills contain satiating ingredients that reduce the temptation to snack. For example, dietary fiber absorbs liquid during digestion and expands in the stomach. This effect allows you to feel full throughout the day, removing the desire to munch on sweet treats.
Supplements Energy Levels
Anyone who has tried to lose weight knows that it can be physically draining. Extensive workout sessions zap your energy, leaving you feeling sluggish. Fortunately, top-tier natural fat burners bolster your energy levels and keep you from crashing.
Ingredients like caffeine and chromium picolinate add the necessary pep to your step. They provide a steady stream of energy so that you can conquer your workout and the rest of your day.
Top Ingredients Found in the Most Effective Fat-Burning Pills
Caffeine
Your daily cup of joe can work wonders for your waistline. The key ingredient, caffeine, can improve your mood and physical performance. Studies show that people who consume caffeine before workouts exercise for 17% longer than their non-caffeinated peers.
Many of the best fat burners leverage caffeine to increase metabolism. The substance speeds up the metabolic rate, forcing the body to burn calories faster.
Researchers from The American Journal of Clinical Nutrition had participants drink 100 mg of caffeine every two hours. They discovered that users burned 150 more calories than people with average metabolisms.
Green Tea Extract
An occasional cup of green tea serves as a delectable way to shed body fat. The antioxidant-rich beverage can also reduce your risk of heart disease and various types of cancer. It works by amplifying your metabolism with a sizable dose of epigallocatechin gallate (EGCG), an antioxidant that aids in weight loss and fat burning.
One study had healthy men take the compound during a cycling workout. The riders who received EGCG rode for 17% longer than individuals who took the placebo.
Conjugated Linoleic Acid (CLA)
We all know trans fats rank among the least healthy foods. Conjugated linoleic acid provides a healthy alternative to boost metabolism and attack fat. If you want to supplement your diet, you can find the polyunsaturated fatty acid in cottage milk, cheese, and beef.
One study tested CLA’s efficacy as a weight loss supplement by giving participants a regular dose for six months. People who received conjugated linoleic acid lost three more pounds on average than those in the placebo group. (Note that CLA may not be the best fat burner for you if you have a lactose sensitivity.)
Garcinia Cambogia Extract
Garcinia cambogia achieved mainstream popularity after Dr. Oz promoted it on his eponymous show in 2012. The small green tropical fruit contains hydroxycitric acid (HCA), which can assist in weight loss. It gives people more control over their appetite while blocking fat storage.
Researchers are still learning what makes garcinia cambogia one of the best fat burners. Experts believe it blocks an enzyme that converts food into fat. This reaction not only mitigates weight gain but also increases serotonin levels in some cases.
Green Coffee Bean Extract
Green coffee beans are the same as unroasted coffee beans. The roasting process extracts some of the potency and health benefits that make these beans one of the best natural fat burners. Multiple studies prove that the extract contributes to fat burning and higher metabolism.
A review of three independent studies looked at its impact on weight loss. Researchers found that people who consumed green coffee lost 5.4 more pounds on average than people who took a placebo. Experts also believe it can regulate blood pressure and blood sugar levels.
Glucomannan
Multiple fat burners on our list contain glucomannan. Why? The dietary fiber excels at making people feel full. This byproduct of konjac root, also known as elephant yam, absorbs water in the gut so that individuals experience satiation for hours.
Glucomannan can also improve blood glucose levels and combat constipation. One study determined that people who took glucomannan with a healthy diet were able to lose eight to ten pounds over five weeks.
Chromium Picolinate
Chromium picolinate is one of the best fat burners that no one knows about. It plays a central role in glucose metabolism while regulating insulin levels. It keeps a person’s blood sugar levels in check. As a result, they experience fewer cravings for sugary snacks.
Chromium picolinate keeps hunger levels down so that people don’t eat more calories than necessary. Although you can find this fat burner in supplements like Instant Knockout and PhenQ, it’s also available in broccoli, potatoes, whole grains, beef, poultry, and dairy products.
Are Natural Fat Burners Safe?
Natural fat burners serve as a safe alternative to prescription products. They contain beneficial ingredients that you can find in everyday foods like coffee, peppers, broccoli, and red meat. As long as you use the fat burner as instructed, you shouldn’t experience meaningful side effects.
Some fat burners are effective because they contain stimulants like green tea and green coffee bean extract. While they prevent weight gain, they may leave you feeling overstimulated. Consider investing in a stimulant-free fat burner if you experience undesirable symptoms.
If you have any questions or concerns about a supplement, contact your doctor. Your doctor knows your medical history and what you need to initiate weight loss. A doctor can point you toward the best fat burner based on your unique medical history, diet, and goals.
Final Thoughts — Are Fat Burners Right for You?
You stand to benefit from one of these top fat burners if you’re struggling to lose weight through diet and exercise alone. These natural supplements rev up the body’s metabolism and make it target stubborn fat stores.
Remember that the best fat burners work around your needs and preferences. For instance, you shouldn’t buy a product that only focuses on leanness if you want to gain muscle. Also, an appetite suppressant might not make sense if you already have a healthy diet.
Finding the right fat burner can simplify your weight loss experience. You can start burning belly fat without compromising your energy levels or focus. Make sure to maintain a consistent and balanced routine, and you’ll achieve your fat loss goals in no time.
