You’ll help individuals learn food concepts and you’ll evaluate clients current diets. You’ll make recommendations on how clients can change their diets in order to lose weight, gain weight and eat a healthier diet.

Certain clients will have specific dietary deficiencies that need correcting. While others may benefit from taking nutritional supplements.

Some clients need to have their calorie counts and nutritional needs closely analysed before starting a dietary program.

As a nutritionist you’ll produce nutrition plans and access the clients nutritional needs.

Education is crucial to your job as a nutritionist because only through teaching the client the proper way to eat, can long lasting changes be made in the clients lifestyle.

Understanding how the digestive tract works can be important in determining the cause of an individuals nutritional complaint. Often this means working with the client’s doctor.
  • A good nutritional consultant also has knowledge of the components of food, including fats, proteins, carbohydrate, vitamins and minerals. They also know which foods are the best for obtaining those required items and which foods to avoid, if necessary.
