According to the School of Sport and Exercise Sciences at University of Birmingham, “The term ‘fat burner’ is used to describe nutrition supplements that are claimed to acutely increase fat metabolism or energy expenditure, impair fat absorption, increase weight loss, increase fat oxidation during exercise, or somehow cause long-term adaptations that promote fat metabolism.” (3)
Looking to lose weight fast in a healthy way? It’s tempting to turn to quick fixes like taking weight loss pills marketed as natural “fat burners.” In fact, surveys show that approximately 15 percent of U.S. adults have now used weight-loss dietary supplements at some point in their lives, with more women (around 20 percent) reporting use compared to men. (1) But before experimenting with these products, consider the fact that most diet pills, drinks and formulas (even those labeled “natural”) are capable of causing a range of unexpected side effects and interactions.
The amount of a fat burner supplement that you should take depends based on what ingredients are in your supplement. It is generally best to follow the instructions on the label so that you are not taking too much each day. It is often good practice to start off at the lower range of the suggested dose, especially at the beginning. This will allow you to make sure your body responds well to the supplement.
One of the best ways to get the benefits of green tea is to consume matcha green tea, a concentrated powdered green tea from Japan that seems to have some noteworthy fat-burning benefits. What’s in matcha that makes it so beneficial for everything from cognitive function to enhancing fat-burning? It’s the catechins, a type of antioxidant found in high levels in green tea that may reduce body weight, speed up recovery following workouts and decrease free radical damage.
There are tons of supplements available, but not all of them keep your overall happiness and health as a top priority. Some fat burners may be effective at burning fat, but they may make you hungry all the time. When this happens, you may either feel like you are starving, or it will make you eat more and gain the weight right back. Other supplements may make you feel weak and energy deprived. This makes it hard to function throughout the day and can make exercise much less effective.
Guarana: Guarana has among the highest concentrations of caffeine in any plant; it contain up to 3.5 percent to 5.8 percent caffeine by volume, while coffee only has up to 2 percent. For increased energy and enhanced mental focus, some people use between 200 to 800 milligrams of guarana a day, which seems to be generally safe. However, side effects for some can include those similar to consuming too caffeine, such as difficulty sleeping, indigestion, anxiety, changes in blood pressure, dependence and a quickened heartbeat. Guarana can also interact with medicines like some antidepressants, lithium, sedatives, other stimulants and blood thinners.
Ansari says alcohol can prevent weight loss in several ways, including the fact that heavy alcohol intake can stimulate food intake. "Binge drinking can overload the liver. The liver then prioritizes processing alcohol over other nutrients and then stores the protein, carbs, and fat as fat in the body," Ansari explains. The Centers for Disease Control and Prevention (CDC) defines binge drinking as having five or more drinks for men, and four or more drinks for women in two hours. "Also, alcoholic beverages are often mixed with sugar-rich beverages. Drinking more than moderate amounts of alcohol can cause calories to add up quickly," she says.
Chromium might help increase lean muscle mass, promote fat loss and reduces food intake. Research findings suggest that chromium usually has “minimal effect on body weight and body fat,” but the good news is that it also doesn’t seem to pose risks. There have been very little safety concerns reported at low to moderate intakes (25–45 micrograms a day for adults), although at higher doses headaches, watery stools or constipation are possible.
Adding a fat-burning supplement to your regimen to help burn belly fat won't necessarily be detrimental, but it's unlikely to do much good, either. You should always check with your doctor before you start taking a new supplement 1. According to personal trainer Christian Finn, the best ways for men to burn fat fast are to eat less than they burn, lift weights two to three times per week, eat a protein-rich diet and add in some cardiovascular work.
