Fat burners act by raising the body’s metabolism, decreasing one’s appetite or blocking fat absorption, among other methods.
Many of these products can help you to lose weight, say dietitians.
But there’s a catch: After you stop taking them, there is a high chance that you will regain the weight.
Sometimes, you may end up even heavier than what you started off at, especially if you have not adopted a healthy diet and exercise regimen.
It’s best to avoid fat burners, as they can cause side effects, such as a rapid heart rate, constipation, an elevated blood pressure and sleeplessness, warn experts.
Some also contain ephedrine, which may cause dependence on the product.
Other ingredients like aspirin may cause bleeding.
Incorporating a balanced diet and exercise remains the safest route to take for long-term benefits.
