Effective ingredients Precautions How to lose fat safely Summary Fat burners are any dietary supplements or related substances that claim to burn excess fat from your body. Caffeine and catechins, its active ingredients, may slightly increase your metabolic rate.
Most studies have mixed results, though. A July review published in the European Journal of Clinical Nutrition assessed the anti-obesity effects of green tea. Some studies showed that green tea extract may reduce fat mass, waist circumference and body weight, while others didn't report any major improvements. In most clinical trials, this compound produced better results when used as part of a diet and exercise plan. More research is needed to confirm its efficacy.
Always take green tea extract with food. This compound may affect your liver when ingested on an empty stomach. Despite its high antioxidant levels, green tea extract isn't entirely safe.
Hypertension, digestive distress, nausea and liver dysfunction are all potential side effects, as the NIH points out. Taking this supplement on an empty stomach may increase the risk of liver damage.
A popular ingredient in weight loss pills is caffeine. This compound may support weight loss maintenance, according to another review featured in the European Journal of Clinical Nutrition in April In clinical trials, subjects who managed to keep the pounds off reported drinking more coffee and caffeinated beverages compared to the control groups. Furthermore, a January research paper published in the Journal of Basic and Clinical Physiology and Pharmacology suggests that caffeine may inhibit hunger and increase satiety, making it easier to reduce your food intake.
In one study in the review, food intake was reduced by more than 20 percent in men who ingested this compound. Women didn't experience this effect, though. Caffeine appears to be even more effective for appetite control when combined with red pepper, soluble fiber or green tea catechins.
The same source indicates that caffeine intake may increase energy expenditure due to its thermogenic properties. To put it simply, caffeine elevates core body temperature, leading to more calories burned throughout the day. Again, most studies were small and had conflicting results.
Try not to exceed 3 to 6 milligrams of caffeine per kilogram of body weight, recommends a May review on caffeine-related deaths published in the scientific journal Nutrients. One cup of brewed coffee has around 95 to milligrams. Protein is incredibly important for burning fat. A high protein intake can help you burn fat by boosting your metabolism and curbing your appetite. It also helps your body preserve muscle mass 19 , 20 , For instance, a study in 60 overweight and obese participants found that a high-protein diet was almost twice as effective as a moderate-protein diet at burning fat While you can get all the protein you need from protein-rich foods, many people still struggle to eat enough protein daily.
Options include whey, casein, soy, egg and hemp protein powders. Keep in mind that calories are still important. Protein supplements should simply replace snacks or part of a meal, rather than be added on top of your diet. If you struggle to eat enough protein, try taking 1—2 scoops 25—50 grams of protein powder per day. Summary: Protein supplements are a convenient way to increase your protein intake. There are two different types of fiber — soluble and insoluble. Soluble fiber absorbs water in your digestive tract and forms a viscous gel-like substance Interestingly, studies have shown that soluble fiber can help you burn fat by curbing your appetite 25 , 26 , It can also help reduce levels of the hunger hormone ghrelin 25 , 26 , In addition, soluble fiber helps slow down the delivery of nutrients to the gut.
When this happens, your body takes more time to digest and absorb nutrients, which can leave you feeling full for longer In one study, 17 people consumed diets with varying amounts of fiber and fat. It found that people who ate the most fiber absorbed less fat and fewer calories from their diet While you can get all the soluble fiber you need from food, many people find this challenging. Summary: Soluble fiber supplements can help you burn fat by curbing your appetite and may reduce how many calories you absorb from food.
Some great soluble fiber supplements include glucomannan and psyllium husk. Yohimbine is a substance found in the bark of Pausinystalia yohimbe , a tree found in Central and Western Africa. One popular way to do this is what is known as a "reverse diet," where you gradually and systematically raise calories.
Don't go too low on calories: During your targeted diet phase, the key is to stay in a slight caloric deficit—that means consuming fewer calories than you burn. But don't think that fewer is always better! It's a common myth of fat loss , particularly among women, that an extreme calorie deficit is a good way to get more out of a fat burner. But not forever," explains Susan Hewlings, Ph. Remember, the ultimate goal is feeling good and being healthy, not just looking lean!
A good goal to have in mind is to eat the highest amount of calories you can, while still losing some weight. Be careful with stimulants: If you can't start your day without a cup of coffee and you drink another throughout your day, be careful about choosing a stimulant fat burner. Most fat burners, unless they specifically say they are stimulant-free, contain caffeine, yohimbine, or other stimulants. While you will definitely love the energizing benefits you'd get from such a high caffeine intake, if you're mixing fat burners with multiple cups of coffee or any other caffeine-containing beverage, there is an upper limit for the effectiveness of stimulants—and it's different for everyone.
As nutritionist Alan Flanagan explains in the article " Why Less Sleep Equals More Body Fat ," cutting into the quality of your rest—which excessive stimulants definitely can do—can lead directly to more fat gain. Also, most people who have taken fat burners consistently can tell you at least one story about a time they got more than they bargained for from a single dose and ended up sweaty, jittery, and feeling a little out of sorts.
So before you even get started on your fat burner, make sure to shop around a bit and find the one that best matches your needs and preferences. Read reviews of the most popular fat burners , and don't just jump on the first one you see. There are two main kinds of fat burners: those containing stimulants, and those which are stimulant-free.
Most but not all thermogenic fat burners contain stimulants, usually including caffeine. Caffeinated fat burners are good for people who find it difficult to summon up the energy to do a vigorous workout or lengthy cardio session. Caffeine is also a potent appetite suppressant for those who find that their ravenous cravings get in the way of their results. So yes, there's a very good reason that it's such a popular ingredient in fat-burning supplements!
As effective as caffeine is, though, it's far from the only ingredient in popular fat burners. And it becomes even more effective when combined with some of the others. But to be clear, just because a fat burner has more ingredients doesn't make it better!
Especially if you're new to fat burners, focusing on a few essential ingredients like these is a good place to start. Green Tea: Green tea and green tea extracts have been shown to activate the body's thermogenic fat-burning activity. A study published in the American Journal of Clinical Nutrition found that men who ingested the active ingredient in green tea catechins significantly reduced their total fat area, waist circumference, skinfold thickness, and subcutaneous fat area.
Taken once or twice daily with food, it can also help your body convert stored body fat into energy, leaving you leaner and more defined.
