When it comes to weight loss, many people turn to fat burners as a quick fix. But are they really safe? The truth is, fat burners can be dangerous. They are unregulated, contain questionable ingredients, and are not likely to give you the sculpted shape you desire. In addition, some of the ingredients in fat burners can cause serious side effects such as liver damage, high blood pressure, mood changes, irregular heart rate, strokes, seizures and heart attacks.
Fat burners are nutritional supplements that claim to increase the body's fat burning capacity after consumption. They usually contain ingredients such as caffeine, L-carnitine, green tea, conjugated linoleic acid, forskolin, chromium, yohimbe, glucomannan and raspberry ketones. Caffeine is the main ingredient in most fat burners and can cause unsafe caffeine intake if taken in excess. Fat burners are said to burn fat by increasing fat metabolism, decreasing fat absorption, increasing weight loss and fat oxidation during exercise.
However, there is very little evidence to support the effectiveness of fat burners and more trials are needed to validate efficacy and safety. In addition, taking fat burners that contain guar gum, carnitine, green tea extract, chromium or chitosan may cause nausea and vomiting. It is advisable to stay away from fat burners that are high in caffeine if you have pre-existing heart problems. If you experience any adverse effects after taking a fat burner supplement, stop using it immediately and consult your doctor regarding the dosage of these supplements. In the words of Dr.
Layne Norton: “even the results of the best fat burners are still negligible compared to a proper nutrition and training strategy”. So if you're looking for a way to quickly lose weight, it's best to stick with a healthy diet and exercise plan.
