# What changed when BurnWeek went daily

October 15, 2026 · From the Lab · 6 min read · https://burnweek.fit/blog/why-burnweek-went-daily/

> The app began with a rolling seven-day budget. We replaced it with a day that starts fresh each morning. The reasoning, and what still looks at the week.

**Key takeaways**

- In late June 2026 the rolling 7-day calorie budget was retired; you now set a daily calorie goal and a daily protein goal directly.
- Each day ends when it ends: an over day does not carry into tomorrow, and every new log lands on today unless you choose another day.
- In a meta-regression of 122 evaluations, interventions combining self-monitoring with another self-regulation technique had larger effects than other interventions (0.42 vs 0.26).
- A review of 28 goal-setting studies found some promise for diet and activity change, but only 32% fully supported goal setting (Shilts 2004).
- The week did not disappear: the Plan strip shows seven days, and a Monday report reads the whole week back to you.

## The rolling budget is gone; the day is the unit

The app was first built around a rolling seven-day calorie budget: eat more on Saturday, and the window absorbed it over the following days. In late June 2026 that model was retired. You now set two numbers directly, a daily calorie goal and a daily protein goal, and the Today screen spends the calorie goal down and builds the protein goal up over one day. At midnight the day is over. Nothing carries forward.

The design brief that drove the change fit in four words: we only live today. The questions people actually ask a food log are daily ones: what have I eaten, what is left, what would finish this well. A seven-day window answered a different question, how am I doing across the week, and it answered it on every screen, including the ones where it got in the way. This post covers what changed, the reasoning, and the part the research cannot settle. The general case for a light, attentive record is in the [pillar on mindful eating with numbers](/blog/mindful-eating-with-numbers).

## The old screen and the new one, side by side

| Before (June 2026) | After |
|---|---|
| A rolling 7-day budget, with today's allowance derived from the week so far | A daily calorie goal and a daily protein goal you set yourself |
| A big Saturday lowered what Monday seemed to allow | Each day starts at the full goal |
| A budget you were given by the window | Two goals, calories and protein, shown side by side |
| The week as the running frame | One day on Today; the week lives in the Plan strip, History and a Monday report |

Three smaller rules came with it. An over day is shown as a number, "120 over", not as a debt that the next day inherits. Every new entry lands on today by default, and logging into another day is an explicit choice, which is covered in [every log lands on today](/blog/every-log-lands-on-today). And the evening became a place to finish the day rather than settle an account, the idea behind the [Finish Today redesign](/blog/finish-today-redesign).

## Why the day: where today's decisions are made

The reasoning was about where decisions are made. We chose a daily frame to make today's food decisions easier. A rolling window turns every meal into a small calculation about the past and the future: Tuesday's allowance depends on Saturday. A daily goal keeps the calculation to one day that you can see in full.

Planning fits the same unit. A meal you book for later today counts toward today's numbers as soon as you plan it, drawn as a hatched segment, and logs itself when the day closes if you do not change it. So the question "what is left?" already includes dinner you have decided on, and the answer never depends on a day you cannot see.

There was a second reason, about what the window did after a big day. Under a rolling budget, a heavy Saturday leaves a smaller number on Sunday and Monday. That is arithmetically fair, and it can feel like a debt. The evidence on what guilt and "blown" days do to eating is discussed in the Finish Today post; the short version is that a tracker has little reason to make the day after a big meal feel like repayment.

## What the evidence supports, and what it does not

It would be easy to claim research shows daily goals beat weekly budgets. The studies cited here do not directly compare daily calorie goals with rolling seven-day budgets. What the evidence does support is narrower and still useful.

**Goal setting shows promise, but the evidence is limited.** A review of 28 studies that used goal setting to change diet or physical activity found that 8 of the 13 adult studies designed to test effectiveness had positive results. Studies of goal *characteristics*, such as how near or specific a goal should be, were inconclusive, no study reported a power calculation, and only 32% fully supported goal setting ([Shilts, Horowitz & Townsend, 2004](https://pubmed.ncbi.nlm.nih.gov/15559708/)). So "a daily goal works better than a weekly one" is a design judgment, not a finding.

**Interventions combining self-monitoring with another self-regulation technique were associated with larger effects.** A meta-regression of 122 evaluations of healthy-eating and physical-activity interventions (n = 44,747) found self-monitoring explained more of the difference between studies than any other technique, and interventions that combined it with at least one other self-regulation technique, such as feedback or reviewing goals, had larger effects than other interventions: 0.42 versus 0.26 ([Michie et al., 2009](https://pubmed.ncbi.nlm.nih.gov/19916637/)). The comparison was with other interventions, not self-monitoring alone, so it does not isolate feedback's contribution. A daily goal gives that loop a short cycle: you log, you see what is left, you decide dinner.

**More frequent logging was associated with greater weight loss.** In a 24-week online weight-loss program, at month six, among 93 participants still logging, those who had lost at least 5% logged in 2.4 times daily versus 1.6 for those losing less. Daily logging time did not differ significantly between these groups ([Harvey et al., 2019](https://pubmed.ncbi.nlm.nih.gov/30801989/)). That is observational, and more-engaged people may simply lose more. Designing the screen for quick checks of one day is our preference; the study did not test glances.

The case for reading intake over a whole week, and why a single day is noisy, is laid out in [should you review your calories daily or weekly](/blog/weekly-vs-daily-calorie-tracking), and the energy-balance side of the same question is in [weekly vs daily calorie balance](/blog/weekly-vs-daily-calorie-balance). Both remain true. The change was about which one the main screen leads with, not about whether the week matters.

## Where the week still lives

Going daily did not mean pretending the week does not exist. Weekly thinking moved to the places where it helps and away from the place where it got in the way.

- **The Plan strip** shows seven days, so you can see what is booked and fill a gap ahead of time.
- **History** keeps every past day, with a calendar and recent-day cards.
- **The Monday report** reads the previous seven days back to you: a balance against your target shown as a range, average calories and protein, what went well and what is worth noticing. It provides a scheduled weekly summary, described in the [weekly report launch post](/blog/weekly-report-launch).

What changed is the order of questions. Today answers "what now?". The Monday report provides a scheduled weekly summary; Plan and History remain available whenever you want to look across days.

## FAQ

### Why did the app stop using a weekly calorie budget?

Because we chose to frame food decisions one day at a time, and a rolling budget turned each day's allowance into a sum over the past week, so a big day became a debt the following days had to repay. A daily goal starts fresh each morning.

### Does going over my daily goal reduce tomorrow's calories?

No. An over day is shown as a number for that day only. Tomorrow starts at your full calorie goal.

### Can I still see how my week went?

Yes. The Plan strip shows seven days, History keeps every past day, and each Monday a weekly report summarizes the previous week.

### Does research establish that the new daily approach is better?

No. The studies cited here do not directly compare daily calorie goals with rolling seven-day budgets. The evidence supports self-monitoring with regular feedback; the choice of a daily goal is a design judgment about where decisions are made.
