When it comes to controlling weight or shedding those extra pounds, diet is often the easiest and the first thing that comes to mind. Selecting the right diet is a daunting and tough task. A consultation with a dietician or a nutritionist can be a good start, but people often mistakenly take both of them to be the same person. Advice from both of them can be handy. A dietician often addresses diets for people with existing health issues and a nutritionist on the other hand deals with maintenance of good health with proper diet as well as issues arising out of malnutrition. So, you should choose the right person for your condition.
