What to Track on GLP-1 Medications: The Complete Checklist

GLP-1 Companion · 7 min read

You do not need to track everything. You need to track the right things, at the right frequency. This is the complete list of GLP-1 metrics worth recording — grouped by how often each one belongs in your log. Skip anything that does not fit your life; what matters is consistency over the year, not perfection in week one.

Daily (or Close to It)

A small number of inputs benefit from daily attention. Keep them short — two minutes total.

• Protein intake (grams). The single most important nutrition metric on a GLP-1, because appetite suppression makes protein the first thing to drop.
• Water intake. Dehydration amplifies nausea and constipation.
• Side effects on a 1–10 scale: nausea, fatigue, GI distress. Even a "0" is data.
• Notable food or eating events — first meal that felt large, a meal that triggered nausea, any food aversion.
• Steps, if you wear something that counts them automatically. No reason to track manually.

Weekly

Weekly metrics catch trends without the noise of daily fluctuation.

• Injection — date, dose, site, pen.
• Weight — same day, same time, after using the bathroom, before eating. Once a week is enough; daily weighing adds noise without adding signal.
• Mood and sleep quality — 1–10 scale.
• Food noise — 1–10 scale. One of the most distinctive subjective effects of GLP-1, worth quantifying over time.
• Exercise frequency and types — resistance training sessions matter most for body composition.
• Anything notable — travel, illness, a high-stress event that could affect the week's data.

Monthly

Monthly check-ins are where you see real progress — most of which the scale hides.

• Body measurements — waist (most important), hips, chest, thighs, upper arms.
• Progress photos — front, side, back, same lighting, same clothing, morning of the same day each month.
• Clothing fit — your benchmark pair of jeans or a fitted shirt.
• Average weekly weight from the past 4 weeks — the trend, not the single number.
• Average side-effect severity for the month.
• Two or three non-scale victories — stairs without breath, going to dinner without anxiety, a pant size dropped.

Every 3 Months

Quarterly tracking lines up with most clinical follow-up cadence and is when patterns become statistically meaningful.

• Lab markers if drawn — HbA1c, fasting glucose, lipid panel, ALT/AST, kidney function (creatinine, eGFR).
• Blood pressure trend.
• Resting heart rate trend.
• Dose escalation timing — was your last increase 4 weeks ago, or longer?
• A doctor-visit summary: dose history, side-effect summary, weight trend, lab summary, open questions.

Annually

A few things only need a once-a-year touchpoint, but they matter.

• DEXA scan or body-composition test if available — directly measures fat vs. lean mass, removes scale ambiguity.
• Comprehensive metabolic panel and full lipid panel.
• Thyroid panel (TSH minimum) given the prevalence of co-occurring thyroid conditions.
• Vitamin D, B12, and iron — micronutrient gaps can emerge with reduced food intake over time.
• A written reflection: where you started, where you are, what you would tell yourself at year zero.

What NOT to Track

Over-tracking has real costs — most importantly, anxiety. A few categories tend to harm more than help on a GLP-1.

• Calories — appetite suppression typically pushes calories down on its own. Obsessive calorie tracking on a GLP-1 frequently leads to under-eating and lean-mass loss.
• Daily weight — the day-to-day noise (sodium, hydration, hormonal cycle, glycogen) is much larger than the weekly signal you actually care about.
• Every micronutrient — let your annual labs handle this. Daily micronutrient tracking is a distraction.
• Comparative tracking against other people's timelines — your body, dose, and starting point are not theirs.

How Detailed Should Your Tracking Be?

The right answer is the level of detail you will sustain for 12 months, not the level of detail you can sustain for 12 days. A simple weekly log of injection + weight + protein + side effects for a year is more valuable than a perfect daily spreadsheet for three weeks. Choose a system — paper, notes app, a dedicated GLP-1 tracker app — and stay with it.

On a GLP-1, your record of what happened is more valuable than your prediction of what should happen. Track the events, not the goals.

A Minimum Viable Tracking Routine

If everything above feels like a lot, here is the smallest routine that captures most of the value:

1. Log every injection (date, dose, site).
2. Weigh in once a week at the same time.
3. Rate nausea, fatigue, and food noise once a week on a 1–10 scale.
4. Take body measurements and a progress photo once a month.
5. Pull labs once a quarter or whenever your provider orders them, and record the trend.

That is roughly 5 minutes a week. Done consistently for a year, it produces a clinical record more complete than what most patients arrive with at their follow-ups.

Key Takeaways

• Track at the right cadence: daily for protein and side effects, weekly for injections and weight, monthly for measurements and photos, quarterly for labs.
• Skip calorie counting and daily weigh-ins — they add noise without adding signal on a GLP-1.
• Food noise (1–10 scale) is one of the most distinctive and worth-tracking subjective metrics of the medication.
• The single highest-value output of all this is a quarterly doctor-visit summary.
• A simple system used for 12 months beats a perfect system used for 12 days.
