R. Siggaard et al., WEIGHT-LOSS DURING 12 WEEKS AD-LIBITUM CARBOHYDRATE-RICH DIET IN OVERWEIGHT AND NORMAL-WEIGHT SUBJECTS AT A DANISH WORK-SITE, Obesity research, 4(4), 1996, pp. 347-356
The effect of 12 weeks' ad libitum carbohydrate-rich, low-fat diet on
total body weight, lean body mass, and fat mass was studied in a group
of healthy subjects at a Danish work-site (I) (n=50, BMI = 28.4 +/- 0
.7 kg/m(2)), Sixteen subjects served as controls (C) (BMI = 27.0 +/- 1
.0 kg/m(2)), After 12 weeks the I subjects had decreased their fat int
ake from 39.0 +/- 1.1 energy-% (E%) to 28.0 +/- 1.2 E% and increased t
heir carbohydrate intake from 46.0 +/- 1.1E% to 56.4 +/- 1.1 E% (p<0.0
5 vs. C), Moreover, a significant loss of body weight (4.2 +/- 0.4 kg)
and fat mass (4.4 +/- 0.6 kg) was observed in I (p<0.05 vs. C), The w
eight loss in I was not regained at 24 and 52 weeks' follow-up (82% of
I participating) compared to baseline, The cost per kg lost weight am
ounted to $14.7/person, In conclusion, instructions at a work site in
ad libitum intake of a carbohydrate-rich, low-fat diet resulted in a s
ignificant loss of body weight and fat mass in overweight and normal-w
eight subjects.
