As a nutrition consultant, you will be able to set your own hourly rate. How much you how much money you want to earn. The average nutrition consultant charges anywhere between $30 and $150 per hour. The main factors to consider before you set your price point is the location of your practice (Are you in a rural area, suburbs or city? Or will it be based online like over Skype?), demand, the services you offer, and any packages or discounts you decided to give.
