      "The FFMI reference of 22 is a rough guide: Kouri's 1995 natural ceiling of about 25 was measured in men, and no comparable study exists for women.",
      "VO2max here is the average for untrained women of your age, not a measure of your fitness; a field test gives your own.",
      "Resting metabolism runs slightly higher in the luteal phase than the follicular phase, so treat BMR as a cycle midpoint."
