How to Get Accurate InBody Results: Tips You Need to Know
Discover expert tips from Coach Hamza on achieving accurate InBody scan results. Learn the best practices backed by science to ensure consistent and reliable body composition readings
If you’re using an InBody scan to track your fat, muscle, and water levels, you’ve probably asked yourself:
“Why do my results change even when I’m doing everything right?”
The truth is, the InBody is a powerful tool—but only if you use it correctly.
In this article, you’ll learn the golden rules to get spot-on results every single time, based on both scientific research and the practical experience of fitness professionals—including Coach Hamza, who’s helped countless clients make the most of their scans.
First, What Is the InBody Scanner?
The InBody device uses a method called Bioelectrical Impedance Analysis (BIA), which sends a tiny electrical current through your body to estimate how much fat, muscle, and water you have.
While it’s super advanced, your daily habits can mess with the accuracy—even something as simple as drinking water or hitting the gym beforehand.
The Golden Rules for InBody Accuracy
1. Always Scan at the Same Time of Day
The best time to scan is in the morning, on an empty stomach, after going to the bathroom and before working out.
Coach Hamza emphasizes that body fluid levels can fluctuate throughout the day, which directly impacts InBody results.

2. No Food or Drink Before Your Scan
Even a glass of water can affect the readings.
To get the most accurate numbers, fast for 6–8 hours before stepping on the machine.
3. Avoid Working Out Beforehand
Exercise—especially intense cardio or leg day—causes your muscles to retain fluid, which can throw off the scan.
According to Coach Hamza, it’s best to wait at least 8 hours after training before scanning.
4. Be Consistent With Clothing and Device
Always scan with similar clothes (or none at all) and try to use the same InBody machine. Even small factors like sock material or skin moisture can skew the results.
5. Ladies: Skip the Scan During Your Period
Hormonal shifts and fluid retention during menstruation can make the results inaccurate.
Wait 3–4 days after your period ends to get a more consistent reading.
6. Get a Good Night’s Sleep
Lack of sleep can cause fluid imbalance and increase body stress, which affects your readings.
A study in the Journal of Clinical Sleep Medicine showed that poor sleep alters body composition readings by affecting water distribution.
How Often Should You Scan?
Not every week!
Coach Hamza recommends scanning every 3–4 weeks under the same conditions.
That way, you can spot meaningful progress instead of getting stressed over daily fluctuations.
Final Thoughts
The InBody scan is a powerful fitness tracker, but like any tool, it only works if you know how to use it properly.
Stick to the golden rules shared by Coach Hamza, and you’ll get readings that actually reflect your progress—not random numbers.
And remember: your scan is just one part of the fitness puzzle. Combine it with proper training, smart nutrition, and consistency for real results.
