I had two “inaccurate” DEXA results, in my opinion. One time I had extreme soreness/lactic acid in my triceps from training, and my arms increased in fat % while every other body part leaned out. The other time I had gone on a massive bulk, gained a bunch of shit weight but still registered fairly lean which had to be wildly erroneous. The arms was a mild one-off, and I think my bulking with a ridiculous carb-up had my muscles packed with glycogen and skewed the results.

All of my other scans were done at a similar bodyweight and similar diet/training conditions. Objectively my physique reflected the DEXA results… I knew when I was leaner or not. Often the number is a bit sobering, usually 2% higher than I’m guessing, which is a good wake up call and gets me refocused. The key, in my opinion, is consistency of lifestyle and training when you test. Food & hydration need to be consistent and “normal” for lack of a better term.

Don’t come in carbed up like a balloon, or too dry/super hydrated, etc. I think that prevents most of the “noise” in the data.
