The GMI Engine learns about your nutrient deficits, excesses, and your food preferences by analyzing your food logs. Careful food logging helps us make better suggestions about ways to improve your GMI. Below are some tips for estimating portion sizes.
A portion is the amount of a given food that you ate at a meal. A portion has a quantity and a serving unit, which can be updated from the log screen once a food is logged.
Estimating portions is a new skill for most people, so it takes a bit of practice. You might try measuring your food and drinks with measuring cups and measuring spoons the first few days that you log. This will give you a better idea of portion size, and will enable you to track your calories and nutrients with better accuracy.
