Interestingly, when I was part of a weight loss diet study at my local university I actually gained muscle whilst losing weight.

I had multiple full body dexascans during the programme.

I didn’t change my exercise routine at all. I wasn’t hitting the gym or doing weights, just my usual basic cardio.

And I gained muscle and lost ~10kilos in weight.

It wasn’t much muscle, but the amount of muscle was higher than before.

The latest research I’ve pulled suggests that DEXA scans are fairly inaccurate and aren’t a reliable way to measure body composition even for the same person across time.

MRI is the gold standard, everything else is pretty loosely goosey.

Sorry, no references but this comes up pretty often in the science based lifting communities on Reddit and YouTube if you want to learn more.

		https://macrofactorapp.com/body-composition/ Estimates in level of inaccuracy on the high end ranges from ~5% to ~10% If you see your lean mass going up in DEXA, your muscles are getting larger, and you're getting stronger, particularly across a wide variety of exercises where CNS adaptation can't explain the strength gains, they're likely broadly accurate. Mine have all tracked quite closely with what I'm seeing in the mirror and what is happening when it comes to the amount of weight I'm moving.
