Use of an expanded-whole-wheat product in the reduction of body weight and serum lipids in obese females.

ABSTRACT

To achieve weight reduction and alter serum lipid profiles, an air-expanded whole-wheat protein product (SNW) was used by moderately obese women as a meal substitute for 12 wk. Results were compared with those from a standard low-calorie diet (LCD). The SNW group lost 3.9 kg (means) over the first 6 wk and a further 1.6 kg between weeks 6 and 12. In contrast, the LCD group lost 2.8 kg during the initial 6 wk but failed to achieve weight loss during the second 6 wk. Consequently, the SNW group lost nearly twice as much weight over the 12-wk period as did LCD participants. A beneficial effect of SNW on serum cholesterol and triglycerides was noted; both measures declined in conjunction with the weight loss. Such alterations were greater in the SNW group than in LCD participants. Both schemes proved safe. SNW is safe and effective in weight reduction and serum lipid modification in moderately obese women.
