Sum logged calories for a day or week.
A calorie log is only informative once it is averaged, because single days swing widely with training, social meals and sleep. Dividing the logged total by the number of days logged gives the figure that actually predicts weight change, and multiplying by seven projects a full week from a partial one. The running balance against target accumulates across every logged day, which is why a small daily overshoot is worth catching early: 150 kcal a day is about 4,500 kcal a month.
Averages
Daily average = total logged / days logged; per entry = total logged / entry count
Running balance
Cumulative balance = total logged - (daily target x days logged)
These figures are population-average estimates for general planning only and are not medical or dietetic advice. Individual energy and nutrient needs vary widely with body composition, activity, medication and health status. Consult a qualified health professional or registered dietitian before making significant changes to what you eat, and especially if you are pregnant or breastfeeding, are under 18, or have a medical condition or a history of disordered eating.
Seven consecutive days including a weekend. Weekday-only logging typically reads 200 to 400 kcal a day low because weekend eating is both larger and less well recorded.
For the average, no — only the total and the day count matter. The per-entry figure is a sanity check: if it lands near 800 kcal you are almost certainly logging whole meals as single items and losing accuracy.
