Why the InBody Scan Is the Most Important Part of Your Weight Loss Program
The scale can’t tell you what’s changing… but this can.
Congratulations, you’ve been on GLP-1s for awhile now and you’ve lost weight! But it’s confusing… you’re stepping on the scale every morning. Some days it drops. Some days it climbs back up. Some weeks it doesn't move AT ALL. You’re eating less, moving more, taking your medication, and still feeling confused.
“Why am I losing weight but not looking different?”
“Why does my shape feel the same?”
“Why do I feel tired even though I’m eating less?”
“What’s actually working?”
These are the questions the scale can’t answer. That’s why every client in our weight optimization program gets a tool that replaces guessing with clarity: the InBody scan.
Our providers walk you through your full InBody report explaining what every number means, what’s actually changing in your body, and what to do next.
What the InBody Scan Actually Measures
The InBody is a medical-grade, body composition analyzer that shows what your body is made of not just how much it weighs.
In about 60 seconds, it gives you a full breakdown of:
Total body weight (what most people track, but it’s only step one)
Body fat percentage (BFP)
Visceral fat level
Skeletal muscle mass
Segmental muscle distribution
Water balance + hydration levels
Basal metabolic rate (BMR)
Phase angle (cell health + inflammation)
This tells us how your body is adapting, changing, and metabolizing so we can guide your weight loss journey with precision.
Why We Don’t Just Use the Scale
The scale is one number. But your body is many systems. Let’s say you lose 8 pounds.
Without a scan, you don’t know:
Was it fat?
Was it muscle?
Was it water or inflammation loss?
Did your metabolic rate drop or stay steady?
Is your visceral fat changing or stuck?
You could “lose weight” while becoming metabolically weaker. You could stay the same weight while becoming stronger and leaner. Without body composition data, you’re just reacting to numbers—and often, punishing yourself for nothing.
The Most Important InBody Metrics We Track
How we break it down at Core Aesthetic:
Body Fat Percentage (BFP)
This tells us what percentage of your total body weight is fat.
Why it matters: You want to lose fat, not just “weight.” Two people can weigh 160 lbs—but one might be 28% body fat, and the other 18%. We use this to track actual fat loss progress, even when the scale doesn’t move.
Ideal ranges:
Men: 10–20%
Women: 18–28% (Depending on age, goals, and muscle mass)
Visceral Fat Level
This is fat stored around your organs, not under your skin.
Why it matters:
It's inflammatory
It raises your risk for insulin resistance, heart disease, and PCOS
It creates a “hard belly” look that resists calorie cutting
It holds on during stress
You can’t “see” this fat but we can measure it. And often, this drops even when the scale doesn’t. That’s a huge win!
Skeletal Muscle Mass
This is how much lean muscle you have, especially across your arms, legs, and core.
Why it matters: Muscle is metabolically active. It helps you burn fat, regulate blood sugar, and feel strong.
On GLP-1s, appetite drops. That means:
You may eat too little protein
You risk losing muscle instead of fat
Your metabolism slows as muscle drops
We use this number to protect your muscle, adjust your protein intake, and help you feel toned. not depleted.
Basal Metabolic Rate (BMR)
This tells us how many calories your body burns at rest.
Why it matters: Your metabolism isn’t static. If you lose muscle, your BMR goes down… and your body burns fewer calories each day. That’s how people hit plateaus or rebound after weight loss.
We monitor this closely to:
Make sure we’re not pushing your body into metabolic slowdown
Help calculate your real intake needs
Determine when to increase activity or nutrition
Hydration plays a major role in weight loss: supporting metabolism, fat breakdown, digestion, and energy. If you're under-hydrated, your body holds on to inflammation, stalls progress, and slows everything down.
Segmental Muscle Balance
This breaks down how your muscle is distributed across your:
Right and left arms
Trunk/core
Right and left legs
Why it matters: This tells us if you’re building evenly or compensating. If your core is weak, or your legs are overdeveloped, we can guide targeted training or EvolveX body contouring.
Water Balance + Hydration
InBody separates intracellular and extracellular water to detect inflammation or dehydration.
Why it matters:
Low hydration = scale fluctuations, low energy, poor recovery
It explains why the scale might go up without fat gain
It shows us if your cells are well-nourished or depleted
How We Use This Data to Guide Your Weight Loss Journey
This isn’t just a “check-in.” It’s a major strategy tool for your weight loss journey on GLP-1s.
We use your InBody data to:
Adjust your GLP-1 dose or frequency
Increase protein or electrolyte support
Recommend movement plans (even just walking or strength basics)
Add Lipo-Mino injections when your metabolism needs support
Pair with EvolveX if belly fat isn’t shifting
Address hydration, inflammation, or muscle imbalances
This allows us to catch:
Muscle loss before it stalls your metabolism
Dehydration before you hit fatigue
Hidden inflammation before it blocks fat loss
(And it gives you visible proof of what’s working).
What Most Programs Miss (And We Don’t)
Other weight loss programs give you:
A scale
A meal plan
A follow-up in 30 days
But they don’t tell you:
If you’re losing the right kind of weight
If your body is adapting well or poorly
Or what to change when the scale stalls
At Core, your InBody scan helps us make real-time, strategic adjustments that keep you progressing without burning out.
If You Can’t Measure What’s Changing, You Can’t Keep It
Fat loss is science, not guessing. Your progress deserves more than a number on the scale.
When you see what’s really changing underneath, you don’t panic when the weight stalls. You don’t fall off or self-sabotage. You stay focused and informed. And you build something that actually lasts.
Contact us if your weight is dropping but your body isn’t changing: we’ll help you see what’s really going on.
