Weekly Review

A weekly review is a scheduled check-in with your own tracking data — calories, macros, weight trend, patterns — typically taking 10–20 minutes once a week. It's the habit that separates "I'm logging food" from "I'm actually learning something from logging food." Most of the long-term value of calorie tracking comes from what you do at weekly review time, not from the daily logging itself.

Why daily numbers are noisy

A single day of calorie data is almost useless as a decision input:

• Daily calorie variance of ±300–500 kcal is normal even with careful logging.
• Daily weight variance of ±1–2 kg is normal from water, sodium, digestion, sleep.
• Daily protein variance doesn't mean much if the weekly average is fine.

Averaging across 7 days smooths out most of this. Week-over-week comparisons reveal the real trends.

What to look at in a weekly review

1. Average daily calories for the week. Compare to your target. A 100–150 kcal drift is normal; 300+ kcal consistent over multiple weeks needs attention.
2. Average protein. Was it adequate (within 10% of target)?
3. 7-day and 30-day adherence. Which days did you skip? Was there a pattern (weekends, work stress)?
4. Weight trend. Use a rolling 7-day average, not a single morning. Is the direction matching your goal?
5. Meals that surprised you. Was there a specific meal that blew up your log? A pattern (weekend takeout, work lunches)?
6. Friction points. Was there a meal type you kept skipping because logging it was painful?

What to adjust coming out of review

Not every review needs a change. In fact, most shouldn't — change the target too often and you lose the signal. Adjust when:

• Weight trend has been flat for 2–3 weeks in a deficit (calorie target too high).
• Weight is dropping faster than 0.5–1% body weight per week in a deficit (target too low, unsustainable).
• You've consistently missed a macro by >15% (rethink the target or the meal pattern).
• Adherence is under 50% over two weeks (too aggressive, too much friction, or burnout is setting in).

Tools that help

• MacroFactor does a version of this automatically — weekly adherence and weight trend drive target adjustments.
• Cronometer has built-in weekly summary views.
• MyFitnessPal shows weekly nutrition averages in reports.
• Lose It! has weekly trend graphs.
• Yazio provides weekly summaries in its diary.

If your app doesn't surface the numbers you care about, a 5-minute spreadsheet (date, calories, weight, note) works fine.

A practical ritual

Sunday evening, 6–7 PM. 10 minutes. Phone in one hand, coffee in the other. Look at last week's numbers. Write 2–3 bullets in a notes app: "Average calories were 1880 (target 1900, fine). Weight trend down 0.3 kg. Weekend logging was rough on Saturday — tried photo logging, worked. Adjust nothing this week." That bullet becomes your memory of the week, and next Sunday you have context when you open it again.

What to avoid

• Mid-week panic reviews. One bad day ≠ a failing week.
• Chasing the scale. Weight is output; food and movement are inputs. Adjust inputs based on trends, not individual readings.
• Moralizing. "I was bad on Saturday" isn't data; it's noise that gets in the way of the adjustment question.

Coaching note

The weekly review is where tracking stops being a punishment and starts being a feedback loop. Most people who track for years do something like this. Most people who quit within three months don't.
