A little clarity starts here.
Enter your details to see your daily block estimate.
Understanding your result
The original method rounds fat weight, lean body mass and daily protein before calculating a daily block count. Its activity labels and meal allocation have been preserved. The standard estimate handles pounds and kilograms consistently.
This is an educational estimate. The original meal table has known inconsistencies. The results identify any missing or mismatched allocation rather than inventing a replacement.
Choose the unit that matches the number you enter. Changing units does not convert the number already in the field.

First, check that the weight unit matches your entry. Next, review the activity labels. The Zone Prescription Calculator uses the standard estimate and handles the selected weight unit consistently.
Then treat the daily total as a worksheet input. You can transfer the public block number into the planner, but the historical meal table does not become a validated eating schedule. Finally, compare the resulting foods, energy and separate macro counts before treating a generated plan as useful for your circumstances.
