This nutrition disclaimer explains the limits of the website’s educational tools, source data and meal estimates. My Zone Journey provides general education about the Zone framework, food measurements and nutrition calculations. It does not provide a diagnosis, treatment, medical nutrition therapy or a personal diet prescription. Reading the site or using a calculator does not create a clinician-patient relationship.
Nutrition disclaimer: calculator results are estimates
A numerical result reflects the inputs, assumptions, factors and rounding documented for that tool. It does not determine your individual energy, protein or other nutrient requirements. The prescription calculator uses a standard estimate with consistent weight units; this does not establish clinical validation of the entire method. Historical results and meal-table warnings remain visible for transparency.
Do not treat a post-workout estimate as a mandatory extra meal or an individualized recovery protocol. Read the explanation of the selected tool and nutrition methodology, including the distinction between total-fat and historical added-fat equivalents.
Food and recipe numbers have limits
Food composition depends on the selected record, preparation and measured amount. Our source-backed calculations are database estimates, not measurements of your particular food. Product labels and substitutions can differ. Recipes have been checked computationally, not physically kitchen-tested; preparation times are estimates. Follow the linked safety instructions and check your own ingredients and equipment.
A block total does not certify nutritional completeness, allergy safety, suitability for a medical condition or adequate intake for a day of training. Check labels for allergens and do not assume that a category such as vegetarian supplies a complete clinical assessment.
Get advice for your circumstances
Ask an appropriately qualified clinician or registered dietitian before using a new restrictive eating pattern or relying on these tools when you have a medical condition, take medication affected by food intake, are pregnant or breastfeeding, are under 18, or have a current or previous eating disorder. Those examples are not an exhaustive assessment of who needs individualized care. Do not change prescribed treatment based on this website.
Research is not a promise
Our summaries describe selected studies and their limitations. They do not guarantee weight change, disease prevention, hormonal effects or athletic improvement. The site is not presented as professionally medically reviewed unless a specific reviewer and review are actually documented.
For source handling, see Research Standards and the research library. Report factual or calculation errors through Contact, including the affected URL. That contact route is not a clinical service.
