Why are the calories on my plan not adding up correctly to “MyFitnessPal”?
Our Dietitian uses a professional database called “Foodworks” to calculate calories as this is the most accurate and has the latest and most comprehensive food data - using a superior rounding system called Atwater Specific Rounding. This, unlike other rounding systems takes into account the food that the macronutrients are coming from, which subsequently changes the energy density. This leads to a more specific calorie measurement of the food.
Other Apps like MyFitnessPal allow anyone, from retailers to any individual using the app (including you!) to input data that is not professional checked. In addition, the rounding system used is not necessarily consistent. Opposed to the Specific rounding system, more commonly, individuals may use the Atwater General Rounding. This gives generic energy densities to Fats (9kcal/g), Carbohydrates (4kcal/g) and Proteins (4kcal/g) without consideration of which food the macronutrients are coming from.
To help in keeping the calories accurate when making changes yourself; we have created a quick substitution guide below.
Quick Substitution Guide
This guide is to be used for making quick food item substitutes. Perhaps you've forgotten to add the odd item to your allergies/dislikes list, or maybe you want to have the option of variety, either way, use this guide as a reference for making food items substitutions.
Substitutions are made using the total calories only, not the macronutrient totals. It is, for this reason, the macronutrient totals will not be mentioned.
