Why Did Germany Lose The Great War?

In my oppinion, Germany could have won the war if they would have kept pushing. With all the allies, Germany still had more men. Throughout the entire war, Germany won many battles and lost less men than the other side. They had good battle plans and strong, dictator like, leaders. I believe, the reason for their loss was the people of Germany. The people were starving from the Blockade and men were dying left and right. After America came into the war, Germany's only allies had surrendered. Germany was all alone and their first solution was to quit because of the horror happening to it's people.
