We tested the effects of a dual‐beverage system comprised of a soluble‐fiber drink and a soluble‐calcium supplement designed to enhance satiety by forming a cross‐linked gel structure in the stomach that is maintained longer than dietary soluble fibers during passage in the gastrointestinal tract. The study was a within‐subjects’, double‐blind, placebo‐controlled study. Test beverages were given before breakfast and in the mid‐afternoon for 7 days. Three fiber doses were used [0 (placebo), 1, and 2.8 g]. Subjects received the calcium supplement with each fiber beverage. Treatment order was counter‐balanced with a one‐week washout between treatments. Fiber drinks contained 40 kcals and were fruit‐flavored to mask differences in taste. Subjects were served buffet‐style lunch and dinner meals and supplied with a take‐out evening snack on Day 1 and 7 of each treatment period. Energy intake at dinner was reduced in both fiber‐beverage conditions (689 and 678 kcal for the 1 g and 2.8 g conditions, respectively) compared to placebo (765 kcal). No differences in intake were noted for evening snack indicating that subjects did not compensate for the lowered energy intake at dinner. No effects were found for energy intake at lunch. In conclusion, ingestion of a calcium‐gelled beverage in the mid‐afternoon reduced spontaneous food intake at dinner in non‐dieting overweight and obese women. Development of foods that enhance satiety may be efficacious for enhancing and maintaining weight loss. Supported by McNeil Nutritionals, Fort Washington, PA.
