My daily calorie goals are randomly changing

We do apologize for any confusion with your nutrients changing with exercise. Hopefully the following information will bring more clarification.

When you create your profile, we ask you for your age, height, weight, gender, and normal daily activity level. We use these factors to determine the calories required to maintain your current weight. We also ask how much weight you would like to lose or gain per week, and with this goal in mind we subtract calories (for weight loss) or add calories (for weight gain) to determine your daily calorie goal.

For more information on how we calculate your initial goals, please see this article: https://myfitnesspal.zendesk.com/hc/articles/360032625391-How-does-MyFitnessPal-calculate-my-initial-goals .

Because your daily calorie goal already accounts for your intent to gain or lose weight at a particular rate, you can achieve your goal by eating the specified number of calories per day, with no additional exercise required. If you do exercise, then your daily calorie goal will increase for the day, to stabilize your weight loss or weight gain at the rate you initially specified.

The calories added to your daily goal are divided among the various nutrients such as fat, carbs, and protein, which is why these increase when you log calories from exercise.

If you are a Premium user or have specific dietary needs, you may wish to exert more control over your nutritional goals. Users who subscribe to MyFitnessPal Premium can modify the effects of logging cardio exercise. This can be helpful, for example, to those who must not consume more than a certain amount of carbs per day, or who may wish to distribute their exercise calories across fat, carbs and protein for specific dietary or performance goals.
