How to Get Accurate Results from Your InBody Scan
The Performance Lab Guide

At The Performance Lab, we use InBody scans to give you real, measurable insight into your progress — not just weight, but muscle mass, body fat, and overall body composition.

 But here’s the key thing most people miss… 

Your results are only as good as the conditions you test under.

If your hydration, food intake, or timing is different each time, your results can fluctuate — even if your body hasn’t actually changed. 

That’s why following a consistent process is essential. 

Why Consistency Matters

InBody scans work by measuring how electrical currents travel through your body. This is heavily influenced by things like: Hydration levels 

Food in your system 

Recent exercise 

Even time of day 

So if you scan after a workout one week, and first thing in the morning the next, you’re not comparing like-for-like. 

At The Performance Lab, we’re not just looking for results — we’re looking for accurate trends over time. 

The Day Before Your Scan 

Preparation starts before you even step into the gym. 

Try to keep everything as normal as possible: 

Stick to your usual fluid intake — don’t overdo it or restrict it 

Avoid alcohol for 24 hours beforehand Keep caffeine intake moderate and avoid excess 

These small factors can significantly influence your readings, particularly body fat percentage. 

On the Day of Your Scan

Your goal here is simple: arrive in a neutral state. 

To do that: 

Avoid eating or training within 3 hours of your scan 

Use the bathroom before testing 

For female members, avoid scanning during your menstrual cycle where possible 

This helps remove variables that can skew your results. 

Right Before You Step on the Scanner 

 A few final steps ensure the most accurate reading: 

Remove heavy clothing like hoodies or jackets 

Empty your pockets (phones, keys, wallets) 

Stand upright for at least 5 minutes before scanning 

Avoid testing immediately after a workout 

Even small things like body temperature and fluid shifts from exercise can impact the scan. 

Best Practice Moving Forward 

If you take one thing from this, let it be this: 

Consistency beats perfection. 

 Try to scan at the same time of day each time (morning or evening) 

Keep your routine similar leading into each scan Don’t panic over one result — focus on trends over time 

Final Word

InBody scans are a powerful tool — when used properly. 

Follow these guidelines, and you’ll give yourself (and your coach) the best possible chance of making informed decisions around your training and nutrition. 

 And remember — the goal isn’t just to get a number. 

 It’s to understand what that number means, and use it to move forward.
