Simply going to the gym might not be ideal to lose weight. You need to focus on improving your diet as well. Also, the quality of sleep matters. Collectively, it’s the workout, diet, and rest that help burn fat and increase lean body mass. Speak to a certified fitness trainer about your goals and work continuously towards them.  Body weight alone is not an appropriate indicator of health. When going to the gym, it is important to maintain a good balance of cardio and strength training and monitor your measurements and lean body mass or body fat percentage regularly for best results.
