Frequently Asked Questions

Do I need to count calories forever to maintain weight?

No, most people do not need to count calories permanently. After tracking for several months, you develop an intuitive sense of portion sizes and calorie content. Many people track periodically to recalibrate or when goals change, rather than indefinitely.

What is the best calorie counting app?

Popular options include MyFitnessPal, Cronometer, Lose It!, and the free USDA FoodData Central. MyFitnessPal has the largest food database, Cronometer is best for micronutrient tracking, and Lose It! offers a user-friendly interface for beginners.

How accurate does calorie counting need to be?

You do not need to be 100% accurate. Being within 10-15% of your target is sufficient for most goals. Consistency matters more than precision. If you consistently estimate the same foods the same way, your tracking will be useful even with small errors.

Should I count exercise calories?

It is generally best not to eat back exercise calories, as machines and apps often overestimate calories burned by 20-50%. If you do add exercise calories, only eat back about half to account for overestimation.
