Values are expressed as means ± SD. Asterisks indicate a significant difference (Student’s t-test: *, P < 0.05; **, P < 0.01; ***, P < 0.001) of 6 HBG subjects from the other 21 of 27 HBG subjects at investigation end.
1Six HBG subjects reported to make heavy handwork all day in outdoor environment during cold winter and to practice “recognizing hunger”.
No significant differences in the five parameters from recruitment. At recruitment mean BG = 86.9±5.3 mg/dL.
221 HBG subjects included 15 that were LBG after seven weeks training (at clinical assessment) and six who had higher mean BG than 100 mg/dL at recruitment.
