Tracking your workouts and your meals together
Tracking intake without knowing what you spend, or the reverse, gives a truncated picture. Keeping both logs in one app is not about balancing calories to the kilocalorie: it is about spotting inconsistent weeks.
What the comparison actually shows
- A heavy training week with very low protein intake.
- Consistently poor sessions after low-calorie days.
- Stable intake but a collapsing training load — often a fatigue signal.
- Missing hydration or breakfast on early-session days.
These are signals, not diagnoses. They exist to raise a question, not to conclude.
Keeping both logs without spending time on them
- Photograph meals instead of typing them: an estimate is enough to read a trend.
- Dictate the session right after training, while the numbers are fresh.
- Check the Health tab once a week, not every day.
- Enter your weight, height and activity level once: targets compute themselves.
Traps to avoid
| Trap | Why it is a problem |
|---|
| “Compensating” a meal with a session | estimates on both sides carry a margin of error |
| Aiming for a calorie deficit every day | performance and recovery suffer |
| Reading a single day's numbers | daily variability is larger than the trend |
| Ignoring perceived intensity | it is the best fatigue indicator available |
A useful log is one you will still be keeping in six weeks.
Method, uncertainty and sources
A photo identifies foods and estimates portions; nutritional values are then matched to reference food data. Oils, sauces and hidden ingredients remain the main uncertainty. Correcting a portion or ingredient recalculates the meal.
- Measurement: quantities you explicitly provide.
- Estimate: visible portions, calories and nutrients inferred from a photo.
- Recommendation: comparison with personalised benchmarks, never a diagnosis.
- References: Mifflin-St Jeor resting-energy equation; ANSES and EFSA nutrition guidance.
Frequently asked questions
Are calories burned reliable?
They are estimates based on duration, declared intensity and your profile. Use them to compare sessions with each other, not as an exact balance sheet.
Should I eat more on training days?
The app prescribes nothing. It shows your intake and training load side by side; the adjustment depends on your goals and, if needed, a health professional.
