A method for slicing meat loafs that have a cross section that varies across their longitudinal extension into accurately weighted slices, that includes the steps of bringing the loaf into a defined shape with a uniform cross section across its length inside a forming tube by pressing the loaf before it is sliced. The pressing is performed in a longitudinal direction and a transversal direction relative to the loaf in a predefined order and in particular in multiple pressing steps. The pressing may also comprise pressure relieving strokes for the purpose of reducing the force exertion for pressing, and for keeping the tissue structure of the loaf intact.
