Many people set a strict daily calorie target and then feel that one higher-calorie meal has undone the whole plan. Working with the total across seven days instead of judging each day separately can reduce that all-or-nothing feeling and make a deficit easier to follow. This guide shows how to turn your TDEE into a weekly calorie budget and place it on a simple week-number calendar.
Why a weekly view fits a one-pound loss goal
The familiar one-pound-per-week rule is already a weekly rule. Calculator.net explains that one pound of body weight is roughly 3,500 calories, and to lose about one pound per week it is recommended to eat about 500 calories below your daily maintenance estimate. Over seven days, that daily 500-calorie reduction adds up to the roughly 3,500-calorie weekly total. If you treat the week as the unit, one higher-calorie day does not erase the plan; you can adjust the remaining days while keeping the seven-day total on target.
This does not mean unlimited feasting on heavier days. The weekly number still has to be realistic, and large single-day swings should stay within a range you can repeat.
Start with your TDEE, not a guess
Use an online TDEE calculator to estimate your maintenance calories from age, sex, height, weight and activity level. The estimate is based on your basal metabolic rate multiplied by an activity factor, generally from about 1.2 for little exercise to about 1.95 for very intense exercise, according to Calculator.net. Mayo Clinic cautions that the result is a starting point, because people judge activity intensity differently and activity levels can change over time.
One calculator example lists a maintenance estimate of 2,480 calories a day and a weight-loss target of 1,980 calories a day for a 500-calorie deficit that aims at about one pound per week. You do not need to use these exact numbers; your own result will come from your details and chosen activity level.
Map the week on a week-number calendar
Once you have a daily target, choose a calendar that displays week numbers and Monday-to-Sunday dates. The year 2026 is a common year starting on Thursday and has 365 days, so a week-number view shows the seven-day blocks clearly. A Danish-language page, Uge Kalender, gives the current week number and a printable annual calendar.
Write your weekly calorie target at the top of the week. Mark the days you already expect to be higher, such as a restaurant meal, a celebration or a long training day, and leave room to adjust the remaining days. Keeping the whole week visible makes it easier to treat the seven-day total, not any single day, as the goal.
Decide which days get more and which get less
Start with your average daily calories, then shift some from days you can eat lighter to days you care about more. If Saturday will be higher, reduce the surrounding days by a small amount each day, or concentrate the reduction on one or two lower days. The weekly total stays the same; only the distribution changes.
Keep the largest single-day reduction moderate. Calculator.net advises against lowering calorie intake by more than 1,000 calories a day, and notes that losing more than 2 pounds per week can be unhealthy and may involve muscle loss, which lowers basal metabolic rate. A sustainable weekly plan usually sits well within those limits.
Adjust protein and training days, not just calories
A weekly plan also makes it easier to think about macros. On higher-calorie training days, keep protein steady to support recovery and let the extra calories come largely from carbohydrates around your workout. On lower days, reduce fat or carbohydrate before you cut protein, because preserving muscle matters during a deficit.
If the week includes social events, place them on the calendar before you set the rest of the week, not after. Planned higher-calorie days are easier to balance than unexpected ones.
Put the weekly plan into practice
At the start of each week, set your weekly calorie budget, mark planned higher and lower days, and write down your protein target. Check your intake against the week-to-date total every two or three days rather than every evening. If you are over, reduce the next two days slightly; if you are under, do not force extra food unless you are genuinely hungry or recovering from training.
After two to four weeks, compare your weight trend with the plan. If it is not moving as expected, adjust your daily target and activity level modestly, using your TDEE estimate as a starting point rather than a fixed rule. The goal is a repeatable weekly rhythm, not a perfect day.
