AI Body Scan is transforming the way we track body composition. In this article, you’ll see how it compares to bioimpedance and why it’s a more accurate option for monitoring your physical progress.
On the PersonalGO app, with just two photos taken from your phone, our technology can estimate body composition in a practical and precise way, validated in comparative studies with DEXA, the gold standard in this type of measurement.
In this article, we’ll compare AI body scanning with bioimpedance scales, understand the differences, limitations, and benefits of each method, and show how you can use this technology in your daily life.
What Is AI Body Scan?
AI body scanning is a technology that uses computer vision algorithms to analyze body images and estimate data such as:
- Body fat percentage
- Lean mass
- Body circumferences
- Body Mass Index (BMI)
- Metabolic risk linked to body composition
All of this is done through real-time photos taken with your phone—without expensive equipment or clinic visits.
What Is Bioimpedance?
Bioelectrical impedance analysis (BIA) is a method that measures the body’s resistance to a low-level electrical current. From that, it estimates the amount of water, fat, and lean mass.
Although popular, bioimpedance has important limitations:
- Hydration levels → drinking or not drinking water before the test changes the result.
- Time of day → morning vs. evening can give different readings.
- Food and exercise → meals or workouts right before the test affect the numbers.
- Equipment quality → home-use scales tend to be less accurate than clinical machines.
AI Body Scanning vs. Bioimpedance
| Criteria | AI Body Scan | Bioimpedance |
|---|---|---|
| Practicality | Done with your phone in seconds | Requires a scale or device |
| Cost | Available in apps, low cost | Expensive devices or clinic visits |
| Accuracy | Validated against DEXA as reference | Sensitive to external factors |
| Tracking | Visual reports and history in the app | Numerical results, variable |
| Accessibility | Can be done anywhere | Requires physical equipment |
While bioimpedance results can fluctuate depending on external factors, body scanning provides a more stable and consistent view of progress over time—especially when done monthly.
Why Is Body Scanning More Accurate?
It’s not about “guessing numbers.” PersonalGO’s AI body scan uses mathematical models trained with thousands of bodies analyzed by DEXA. This means every measurement from your phone is compared against a robust database, reducing error.
It also considers circumferences and visual proportions that bioimpedance cannot capture. For example: changes in the abdomen or arms may show up first in scanning photos before they affect your scale weight.
How PersonalGO Uses Body Scanning
With the Premium plan on PersonalGO, users get one body scan per month, directly in the app. This makes it easy to:
- Track fat and lean mass changes
- Measure circumferences without a tape measure
- Compare real changes month by month
- Share results with your trainer to adjust workouts
This is a powerful advantage: instead of relying only on scale weight, users see their full body transformation.
AI Body Scan and Motivation
It’s more than just numbers. Watching your progress visually and in charts helps you stay consistent. Seeing fat decrease, lean mass increase, and graphs improve is a powerful motivator not to quit.
Limitations of AI Body Scan
No technology is perfect. Results can vary if photos are taken with:
- Poor lighting
- Inadequate clothing (too loose or too dark)
- Incorrect posture
But by following the app’s instructions (good lighting, fitted clothing, proper stance), the results are reliable and consistent.
AI Digital Body Scan — Trusted Technology in Your Hands
Bioimpedance still has its place, but for those who want practicality, consistency, and visual tracking, AI body scanning is the smarter choice. It combines accessibility, scientific validation, and ease of use, all from your phone.
With the PersonalGO Premium plan, you’ll have access to this feature, plus an ad-free app and personalized training to maximize results.
If your goal is to monitor your body’s real progress with clarity, body scanning is the way forward.
FAQ – AI Body Scan
Is body scanning reliable?
Yes. The technology has been validated against DEXA, considered the gold standard for body composition analysis.
What’s the difference between body scanning and bioimpedance?
Scanning uses photos and AI to estimate fat, lean mass, and measurements, while bioimpedance relies on an electrical current and is more sensitive to external factors.
Do I need equipment to do body scanning?
No. All you need is a phone camera and an app that provides this feature.
Does body scanning replace clinical exams?
No. It’s a practical, accessible monitoring tool but does not replace medical exams when needed.
