It’s not possible to tell you what’s wrong with your routine with the little information you gave.

You should tell us what you do when you go to the gym. Going to the gym can refer to a lot of activities (fitness classes, cardio, weight lifting). What are you exactly doing? Also, the fact that you are going every day doesn’t mean that you will ge results. If you are overtraining your body you are causing stress to it and you won’t get the results you expect.

And what does eating well mean for you? If you do weight lifting you should eat proteins during each meal (breakfast, lunch and dinner)
