REGISTERED nutritionists know all too well that the New Year creates a huge amount of interest in lifestyle and diet from so-called health gurus. This is easy to see after the festive period as brands use this time to prey on potential customers and encourage them to think they need to invest in a new product or new diet. Some of the diets that do the rounds include Atkins, alkaline, detoxes, cabbage soup, blood type, ketogenic, maple syrup, paleo, juice cleanses, whole 30 and potato. And of course celebrity-endorsed diets with no scientific backing.
