Children and adults can both benefit from having a dietician.

All people with insufficient knowledge about how the body processes food should seek knowledge about foods that will nourish the body versus a diet that consists of a heavy amount of fast food or pre-made dinners. With proper planning, a diet that is rich in vitamins and minerals but lacking excessive fat and sugar-filled content can help with weight loss, energy levels, and overall better health, and a dietician can help people with little knowledge to create such a plan.
