Free calorie & nutrition tracking
A single day tells you almost nothing. The body does not reset its books at midnight; it responds to a longer-term average. That is why a week is a far better measure for weight management than any single day. This page gathers your weekly calories, energy balance, macro averages and longer-term calorie history into one view. When you see the whole week at once, individual dips fall into the right proportion, and there is no need to panic over one big meal.
You see the week's total calories and the daily average, so you can compare the actual figure against your target. The energy balance tells you whether you were on average above or below your expenditure, and estimates what that means for your weight. The macro averages reveal whether protein, for example, is being met as planned. The calorie history chart shows your progress across several weeks, making the trend visible. You can also pick a custom period, such as a month, and view a longer stretch as a single whole.
Energy balance is the difference between how much energy you take in and how much you burn. About 7000 kcal corresponds roughly to one kilo of body fat. If over a week you are on average 500 kcal per day below your expenditure, you build a deficit of about 3500 kcal per week, which corresponds to roughly half a kilo of fat. This is an estimate, not an exact figure, because the body's expenditure varies and measurement carries error. Still, it is a very useful directional measure when you look at several weeks in a row.
Look at the direction, not a single number. If your weight is not moving but you believe you are in a deficit, the weekly view often reveals why: the average is actually closer to balance than you thought, or a few unlogged days distort the picture. If instead your weight is falling steadily and your energy is good, you are on the right track, so change nothing. Give every change at least two or three weeks before drawing conclusions. Weight fluctuates daily with water and gut contents, so a longer window is always more reliable.
Log foods on as many days of the week as you can, because a few empty days skew the average. Weigh yourself at the same time each time, ideally in the morning right after waking, so comparison is fair. Do not be alarmed by a single spike in the chart. That is normal. Instead watch whether the trend line moves in the direction you want. Start tracking with the calorie calculator and set your target with the BMR calculator.
If the weekly trend has genuinely stalled for several weeks, first check whether the log contains enough complete days and whether portion estimates have changed. Energy needs can also change as body weight changes. Avoid automatic or drastic calorie cuts based on one chart. If you decide to make a small adjustment, follow how you feel and how the longer-term trend responds. Ask a qualified professional for help if you are unsure what is appropriate for you.
The biggest benefit of weekly tracking is that it teaches patience. Weight loss does not move as a steady line downward, but in steps, sometimes faster and sometimes stalling. This is completely normal, and it is exactly why you should not draw big conclusions from a single week. When you look at a stretch of several weeks, random variation smooths out and you see the real direction. A realistic target is about half a kilo per week, and even a slower pace is perfectly fine, because it is often more sustainable. If you compare yourself to social media or to other people, remember that everyone's starting point and body is different. What matters is that your own trend moves in the right direction over the longer term. When you give the process time and do not panic over individual dips, tracking becomes an encouraging tool rather than a source of stress.
Why is my weight not dropping even though I am in a deficit?
The most common reason is that the deficit is actually smaller than you think. The weekly view helps you see the average. Water fluctuation can also mask fat loss for several weeks.
How often should I weigh myself?
A few times a week at the same time is plenty. The trend matters more than any single reading.
