The Scale Says I Lost 29 lbs. My InBody Says 37.4 lbs of Fat. Both Are True.

July 10, 2026 | Ben Nelson, Founder of ShredCoach

If you've read this blog, you know my scale story: 221.7 lbs on March 2, 192.3 this morning, 29.4 lbs down in 130 days.

Today I want to show you a different set of numbers — from my InBody body-composition scans — that tell a bigger story. Because the scale, honest as it is, has been quietly underselling this entire cut.

The Two Scorecards

My last InBody scan, taken July 4, against my first one in March:

• Body fat: 32.0% → 17.3% • Fat lost: 37.4 lbs • Lean mass gained: +10.5 lbs • Visceral fat score: 7 → 6

Read those middle two lines again. The scale says I lost about 29 lbs. The composition data says I lost 37.4 lbs of fat — and the books balance because roughly ten and a half pounds of muscle showed up while the fat was leaving.

That's not a rounding error. That's eight pounds of progress the scale never told me about. (The two scorecards even start from slightly different numbers — my March 2 morning weigh-in read 221.7, the first InBody scan that week read 222.8. Different morning, different device. The story they tell is identical.)

The Last 30 Days Are the Whole Argument

Here's the window that would have broken my spirit in any previous diet attempt. Over the past month, my scale weight went up 0.6 lbs. Flat. Worse than flat — backwards, by scale logic.

What actually happened in those 30 days, per the scans:

• Fat: down 2.0 lbs • Muscle: up 1.6 lbs • Body fat percentage: down 1.1 points

If the bathroom scale were my only instrument, I'd have called this month a plateau — maybe even a failure. I'd have cut calories harder, added punishment cardio, or spiraled. Instead, it was arguably the best month of the entire cut: fat left, muscle replaced it, and my body quietly swapped its composition.

This is body recomposition — losing fat and building muscle at the same time. And it makes the scale structurally incapable of telling you the truth.

Why the Scale Can't See It

The scale measures total mass. It has no opinion on what that mass is made of. A pound of muscle and a pound of fat weigh exactly the same — but the muscle takes up about 20% less space, burns more calories at rest, and looks entirely different in a mirror.

So when you're doing the two things every good cut demands — a calorie deficit for the fat, resistance training and high protein for the muscle — you create the exact conditions where the scale fails. Fat leaves (scale goes down), muscle arrives (scale goes back up), and the net number whispers "nothing's happening" while your body is being rebuilt.

Who recomps best? Ironically, the people most likely to quit over a flat scale: beginners returning to lifting, people with meaningful fat to lose, and anyone whose protein intake finally caught up to their training. Sound like you? Then a flat scale month might be the best month you've ever had.

How to Actually Track a Recomp

Weigh daily anyway. The scale isn't useless — it's one instrument in the panel. Daily weights build the trend line, and trends smooth out the water noise I've written about endlessly.

Get composition data on a cycle. An InBody or DEXA scan every 4-8 weeks is the ground truth. That's what settles whether a flat month was a plateau or a recomp. (ShredCoach has a dedicated body-fat tab that takes InBody, DEXA, or manual measurements, right next to your weight trend.)

Use the low-tech instruments too. Progress photos every two weeks, same lighting, same pose. A tape measure at the waist. How your clothes fit. Every one of these catches recomposition that the scale hides.

Judge months, not mornings. Composition change is slow arithmetic. A 30-day window is the minimum honest reading period.

The Takeaway

For 130 days I've told you the scale spikes lie — that water masquerades as fat and panics people out of working plans. Today's lesson is the mirror image: the scale also hides your wins. It couldn't see 8 lbs of my fat loss because muscle covered the evidence.

One number can't referee your body. Track the panel — weight trend, body fat, photos, tape — and let the data tell you what the mirror already suspects.
