I am new, so its possible I am just asking something stupid.
But I would like to select loops without the in-between polygons.
Thank you
Try using edge-ring selection when in edge-selection mode.
Ctrl-Alt-LMB

Thank you !
Now that I read your question again, I think I misunderstood it 
You were probably fine just switching to edge-selection-mode and doing a normal loop-selection.
