I'm pretty new so I take it with a grain of salt-

4 weeks and no lbs dropped and no loss in inches is a true stall. Have you measured? Have you lost inches? Have you measured your body fat? Maybe Skamito is right, maybe you are gaining muscle which is valuable, it burns more calories.

Also, maybe you need to cycle calories a little bit??

Just some ideas, hope something moves soon for you.
