Fat burners are nutritional supplements that claim to help you lose weight quickly. The main ingredient in most fat burners is caffeine, which helps you lose weight by boosting metabolism and helping the body use fat for fuel. It also helps provide energy for exercise and other calorie-burning activities. In the body, caffeine increases the breakdown of fatty acids that reside in adipose tissue, also known as abdominal fat.
Once fatty acids are broken down, they enter the bloodstream and our bodies can burn them for energy. However, if you stop using the stimulant abruptly, your metabolism slows down and you'll gain weight as you recover your normal metabolic rate. As long as you take a reasonable approach to your overall nutrition and monitor your stimulant intake, fat burners can be a sure way to increase your results. The Food and Drug Administration (FDA) does not regulate or approve products such as fat burners before they go on the market.
In addition, most people who have taken fat burners on a consistent basis can tell you at least one story about once they consumed more than they expected with a single dose and ended up sweating, nervous, and feeling a little out of place. Fat burners tend to be a natural (or sometimes unnatural) combination of several herbs and nutrients that act to increase energy levels, stimulate metabolism, and may even help suppress appetite and reduce caloric intake. Often, people take fat-burning supplements in the belief that they will replace the need for exercise, a disciplined diet, or other lifestyle changes needed to lose fat. Over-the-counter fat burners attract patients who want a magical way to treat obesity and believe that their benefits outweigh the risks.
Some fat burners contain stimulants such as caffeine, while others don't contain stimulants, it all depends on your preferences and what you want to achieve. Excessive intake of fat burners can cause liver damage, fluctuations in blood pressure, anxiety, headaches, heart attack, insomnia, and nausea. If you've been struggling to lose weight, you may have considered taking a pill that has been advertised as a fat burner. Fat burners aren't the magic pill that literally burns fat, but they supplement fat burning.
Some herbs, such as ephedra, that were formerly used to burn fat are now banned by the FDA because they cause high blood pressure, mood changes, irregular heart rate, strokes, seizures, and heart attacks. However, the ingredients in fat burners can interact with medications and cause serious problems, so it's important to make sure your doctor is aware before taking them. Kendall recommends not consuming the fat burner for a couple of weeks and then starting over, ideally with a lower dose than you were taking before you quit smoking. Taking into account all these factors is essential when considering whether or not to take a fat burner supplement.
