Let your plan learn
Pro uses complete intake records and trend weight to make measured weekly adjustments.
The method, in plain language.
Start with an estimate, learn from your body.
Total daily energy expenditure (TDEE) includes rest, digestion and movement. We estimate it by multiplying BMR by an activity factor. Consider your whole usual week: desk time, walking, physical work and training. Workout frequency alone can overstate activity if you sit for most of the day. Start with the closest overall level and refine it using consistent intake and weight trends.
The next two weeks matter more than one number.
Save your calorie and macro targets, record meals and weigh yourself under similar conditions. The trend line smooths daily changes caused by water and digestion. Free tracking works without signing up. With Pro and enough complete records, the adaptive engine estimates expenditure from your actual intake and weight trend, then makes bounded weekly adjustments.
BMR estimates energy needed at rest. TDEE also accounts for daily activity. Use TDEE as a starting point for a maintenance target; BMR is not a complete daily food allowance.
Do I need an account to use xfit?
No. Calculation, manual food logging, recipes and trend weights work in your browser. Create a free account to back up and synchronize those records across devices.
How accurate is a calorie calculator?
Population equations cannot know your individual metabolism. Activity estimates, food labels and water changes also introduce uncertainty. Track consistently and review trends rather than treating a single calorie value as exact.
