I keep seeing this 'fat burner' term. So if I stop taking it, will I gain all the weight back?

Fat burners like Arsynist can aid in weight loss by boosting metabolism and energy, but they're not magic pills. They work best when combined with a balanced diet and regular exercise. If you stop taking the supplement but continue to maintain a healthy lifestyle, you should be able to maintain your weight loss. However, if you go back to unhealthy habits, it's possible to regain the weight. It's all about balance! I hope that helps.
