Optimal Nutrition Protocol(ONP) is a science driven programme designed to create a sustainable lifestyle which is personalized by taking environmental conditions, biomarker levels, personal preferences and various other factors into consideration. A routine diagnostic test is prescribed to ascertain the current metabolic status of an individual and to identify any skews from the normal ranges of their biomarker levels. The rest of the information required to generate the recommendations are obtained from a Lifestyle Questionnaire specifically designed for this program.
