What are meal ratings?
Meal ratings are ratings given to each meal you've eaten based on how healthy it was. They appear in the form of smileys next to each meal you have tracked. The ratings are generated by looking at three factors; the proportion of what you ate that was healthy, the proportion of what you ate that was unhealthy, and how well the meal met your daily goal for calories, macronutrients and micronutrients.
How can a food receive a smiley rating in search but receive a totally different rating in my diary/in a meal?
With food ratings, rates are awarded to each food based on its distribution of macro- and micronutrients - carbohydrates, fat, protein, sugar, fiber, and sodium, and it’s calorie density per 100 Cal. When a food is tracked we take into account the amount and how well it matches your diet and daily goals. Remember, Life Rating™ is here to act as a guide on how to be healthy, nothing is set in stone as good or bad.
Ketogenic: On this diet, the ratings focus most on the amount of carb per 100 grams. When you find a food with "A" rating in the search, Lifesum has looked at the carb distribution and quality per 100 grams of that food. If you track it in fairly large amounts, then that food, together with eventual others, will eventually create a good rating, having also taken into account how well the meal fits your daily goal. A food with a good rating in search can, in your diary and meal, together with others, eventually turn into a lower rating if the meal doesn’t fit your macronutrient distribution goals.

Why aren’t all meals rated?
Life Rating™ is based on an algorithm that analyses macronutrients and micronutrients, so without this information meals cannot be rated. If you're tracking with Custom Calories for example, Lifesum won't know the content of the meal and can not rate it.
Why does my meal get a bad rating when I've only tracked happy smiley foods?
In general: One reason can be that the food you’re tracking lacks information about micronutrients (fibers, unsaturated fat, sugar etc.) The rating is automatically lower in this case since the Life Rating™ index uses these values.
Another reason could be that you've eaten too few calories, and in combination with the imbalanced macronutrient content (amount of protein, carbohydrates and fat) the meal gets a lower rating. The meal rating takes into account your food choices and the amounts of each you use to form a meal.
Ketogenic: Even though your choices were good, amounts matter. The meal ratings for Ketogenic diet help you eat according to your macronutrient-distribution per meal and day, and help you so that you don't exceed your carbohydrate limit. If a food gets a good rating in search, that rating is per 100 gram of the food, while the rating on meals reflects the amount of them that was tracked.
High Protein: To obtain the highest rating your meal needs to consist of a considerable amount of protein.
Why is my meal getting a good rating when I've only tracked foods with a sad face?
In general: The meal ratings take into account how well the meal met your daily goal for calories, macronutrients and micronutrients, so that can lead to a better rating. Remember that all foods consist of “better” and “worse” nutrients in different amounts.
Ketogenic: Even though your food choices weren't the best, amounts matter. The meal ratings for the Ketogenic diet help you eat according to your goals for macronutrient-distribution per meal and day, and guide you so you don't exceed your carbohydrate limit. If a food gets a bad rating in search, remember that the food rating is per 100 grams of the food, while the rating on meals reflects the total amount of that food that was tracked. If you ate these "unhappy faces" foods in moderation you may still end up with a good rating.
How can the same kinds of meals get different ratings?
If you track foods that are rated, the meal rating you receive should be fair as all the information about macronutrients and micronutrients is included. If you track the same kinds of food, but they are not all rated, they likely lack information about macronutrients and micronutrients, which can mean the meal gets a rating that is either “too good” or “too bad”.
What happens to my remaining calories or exceeded calories for each meal?
Calories are set for each meal to create a healthy amount so you aren't hungry or overfull. If you eat a meal that is too small or too big, the meals that follow won't be affected as this would make it harder to score well on them. Instead you'll be able to have a snack to reach the goal for the day, or if the case is that you've had too many calories, you may be able to skip a snack or take a walk to be able to reach your daily goal.
What happens to my exercise calories?
When you exercise and are including exercise calories in your calorie goal, it's important to eat more to refuel the body and restore your muscles. All the exercise calories end up in the snack module so that you can “snack up” to reach your daily goal.
