The short answer to this question is that DEXA scans are not an accurate way to measure your body fat. That said, no device can accurately measure how much muscle and fat you have. The only way to truly measure your body fat is to have all of it stripped out, placed on a scale, and weighed.
Is DEXA the most accurate for body fat?

Used incrementally DXA scans tell a more accurate story than BMI, in terms of progress for muscle development and fat loss.
Do DEXA scans overestimate body fat?
DEXA, short for dual-energy X-ray absorptiometry, does a reasonable job at estimating group averages. DEXA might overestimate body fat percentage in half your group by five percent, and underestimate it in the other half by five percent. When looking at the group results, the average error size is zero.
Can you cheat a DEXA scan?

Is DEXA more accurate than Bod Pod?
Bod pod readings were slight underestimations compared to DEXA. The researchers concluded that the bod pod was more accurate when testing people closer to a healthy BMI. The bod pod was less accurate than DEXA when it came to measuring very lean individuals.
Does exercise affect DEXA scan?
