Tracking nutrition and hydration without counting every crumb

Full macro tracking works. It also has a dropout rate that would embarrass most gym memberships, because weighing everything is a part-time job.

Partnexa's Fuel section is built for the middle ground: enough signal to know whether you're eating and drinking enough to recover, without turning dinner into data entry.

What's actually worth tracking

1. 1Protein — the one number that reliably changes how training feels
2. 2Total intake — roughly, in the direction of your goal
3. 3Water — the most under-rated recovery variable
4. 4Timing around sessions — did you eat before training, or not

That's it. Fibre, micronutrients and precise fat splits matter, but they're rarely the thing standing between you and progress.

Saved meals do the heavy lifting

Most people eat about fifteen meals on rotation. Save them once and logging becomes two taps. The first week is the only week that takes effort.

• Save a meal from any logged entry
• Duplicate yesterday in one tap
• Quick-add by portion when you're eating out and guessing

Targets, set from your training

Your protein and intake targets come from your bodyweight, goal and training load, and they shift when your training volume shifts. A heavy block asks for more; a deload asks for less.

You can override any target manually. If you're working with a dietitian, use their numbers — the app will track against whatever you set.

Hydration, the boring win

Dehydration shows up as low readiness, heavy legs and a shorter fuse long before you feel thirsty. The hydration tracker is a tap per glass, with reminders you can shape around your day.

If your readiness scores are quietly sliding and nothing else has changed, check your water before you change your program.

What this is not

It's not a diet, not a meal plan, and not a calorie police force. There are no "bad food" warnings and no streak-shaming for a birthday dinner. Food is fuel and occasionally it's cake.
