Protein and fiber have strong satiety-inducing potential. Beef is a high quality, protein-rich food. Beans contain moderate levels of protein as well as fiber. To determine the effects of a high protein meal (beef) compared to a moderate protein, high fiber meal (beans) on subjective appetite and energy intake at a subsequent meal twenty-eight adults, 14 men (ages 24 ± 5 y, BMI 23 ± 2 kg/m(2) ) and 14 women (ages 25 ± 5 y, BMI 22 ± 2 kg/m(2) ) consumed 2 test lunches containing a "meatloaf" made from either beef or beans. The beef meal provided 26 g of protein and 3 g of fiber while the bean meal provided 17 g of protein and 12 g of fiber. An ad libitum snack was given 3 h after the test meal. Visual analogue scales were used to assess hunger, satiety, fullness, and prospective food intake. Gastrointestinal (GI) tolerance was assessed over 24 h. No difference between the beef and bean was observed for appetite ratings over 3 h, food intake at the subsequent meal (632 ± 75 kcal compared with 611 ± 75 kcal, respectively), or sum of GI score (2.2 ± 0.5 compared with 2.9 ± 0.5, respectively). Gas and bloating were reported more often after the bean meal than the beef meal (2.0 ± 0.4 compared with 1.3 ± 0.4, P value 0.057). A beef-based meal with high protein and a bean-based meal with moderate protein and high fiber produced similar satiety, while the bean-based meal resulting in higher, yet moderate, gas and bloating.
