The colony needs a constant supply of protein and carbohydrates. The protein is for feeding the larvae and queen, since the larvae is growing into an adult ant and the queen has a constant egg laying quest going on. The adult workers are more interested in carbohydrates. They are already fully grown and instead needs energy to be able to work day and night. Protein is found in insects, meat and eggs. Carbohydrates are fed through honey or sugarwater, combining the need of energy and water. Honey, syrup or a wet lump of sugar is also appreciated by the ants.
