Nutrition tracking with calories and macros
LifesOS Nutrition tracks meals, calories, protein, carbs, and fat — with daily totals and trends alongside your activity and weekly report.
Calories or macros? Start with the question you are answering
Calories answer "how much". Macros answer "made of what". If the goal is weight, calories are the lever; if the goal is body composition or steady energy, the split starts to matter. Tracking both from day one is the usual reason people stop by week three.
The distinction is worked through in calories vs macros, and the practical version in how to track macros simply.
Appetite is a signal, not a character flaw
Intake rises during a heavy training block. It rises after short sleep. It rises in a week of late meetings, when dinner arrives at nine and decisions get made by whoever delivers fastest.
Read on its own, that week looks like a lapse in willpower. Read next to training load and the calendar, it usually looks like a predictable response to load — which is a far more useful thing to know, because load can be planned and willpower cannot.
That is the case for keeping food in the same system as movement and time rather than in a dedicated tracker that can only see plates.
Track less than you think you should
Logging every item is the fastest route to logging nothing. Most of the value sits in a handful of meals that repeat and one number you check weekly. The rest is precision you will not use — the argument is in tracking your life without tracking everything.
Meal tracking vs calorie counting covers the lighter approach, and a weekly meal planning routine removes most decisions before the week starts.

Common questions
Do I have to weigh everything?
No. Consistency beats precision — the same rough estimate every day tells you more about the trend than an exact figure you stop recording.
Which should I track first?
Calories, then protein. Add the rest only if a specific goal needs it.
Does it connect to activity?
Yes — intake and training load sit side by side in the Weekly Report, which is where the relationship between them becomes visible.
