Changes in weight and body fat distribution with the step 1 diet
Seventy four moderately hypercholesterolemic men who were part of a larger cholesterol-lowering, double blind, placebo-controlled drug trial, received intensive group and individual nutritional counseling on the use of the National Cholesterol Education Program (NCEP) Step I diet over the course of 48 weeks. Weight was measured at each visit, dietary compliance was assessed at Week 8 and waist, abdominal, and hip circumferences were measured at \Yeek 10. Assessment of dietary compliance and circumference measurements were repeated at Week 48. The results revealed that 53% of subjects decreased their weight by 2.87 +/- 0.4 kg and 43% of subjects increased their weight by 2.57 +/- 0.3 kg over the 48 week period. Subjects who lost weight had significantly greater decreases in abdominal, waist, abdominal-to-hip ratio, and waist-to hip ratio compared to subjects who gained weight. Caloric intake and diet composition did not differ significantly between subjects who lost weight and those who gained. Diet composition, particularly percentage of energy from total fat, was associated with higher body weight, BMI, waist, abdominal, and hip circumferences. Percentage of energy from was not related to abdominal-to-hip ratio or waist-to-hip ratio.
