Could double majoring help my chances of getting in to medical school?

I was thinking of double majoring in psychology and human services and minoring in something else and I did a four-year plan so I found out it is possible provided I do 5 classes a semester. Since that seems kind of hard, I was thinking of just double majoring. But can it help my medical school application in the long-run if I show diverse interests and that I was able to double major with the pre-med courses and general education courses?
