I don't suggest unfriending more than 1 per day. Removing 1 friend will remove 5 points from your highest stat which would be Energy in your case. If you remove a second friend, you'll lose 6 points but only get back 5 when you friend someone else (therefore you'll lose 1 point permanently for each friend removed after the first)
