The BMI doesn't consider many factors such as muscle mass and water retention. Many people fluctuate weight by at least 5-6 pounds daily and depending on many factors can fluctuate by 10 pounds monthly. For an anorexic person this could mean a unhealthy BMI to a healthy one.
BMI conflicts with many health experts and they usually completely disagree with using the BMI alltogether for an indepth review of a patients case.
