TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['The primary aim was to determine whether ready-to-eat cereal used as a portion-controlled, meal replacement promotes weight loss. Additional aims were to determine whether weight loss differed if the cereal was provided as a single brand or variety of brands and whether this use of ready-to-eat cereal promotes continued weight loss following transition to a high-fiber, high-volume (Volumetric) diet.', 'Body composition was measured and diet records, appetite questionnaires and activity logs were completed during baseline and end of intervention weeks 2 and 6. Participants were assigned to one of four treatment groups. Group 1 (6 M, 22 F, mean age 43.0 +/- 1.9 years, mean initial BMI 28.9 +/- 0.4 kg/m(2)) consumed a serving of a single brand of ready-to-eat cereal with 2/3 C skim milk and a 100 Kcal portion of fruit for breakfast and as a replacement for either lunch or dinner for weeks 1 and 2. No restrictions were placed on the non-cereal meal. They then followed the Volumetric diet for weeks 3 to 6 with a target energy restriction of 500 kcal/day. Group 2 (3 M, 25 F, mean age 40.9 +/- 2.3 years, mean initial BMI 29.39 +/- 0.6 kg/m(2)) followed the same protocol, but was permitted to select from a variety of ready-to-eat cereals during weeks 1 and 2. Group 3 (7 M, 19 F, mean age 41.6 +/- 2.4 years, mean initial BMI 29.3 +/- 0.6 kg/m(2)) received no dietary instruction during the six-week study and Group 4 (9 M, 18 F, mean age 38.2 +/- 2.8 years, mean initial BMI 29.3 +/- 0.6 kg/m(2)) received no intervention prior to adoption of the Volumetric diet for weeks 3 to 6.', 'The cereal interventions resulted in 640 +/- 109 and 617 +/- 105 kcal/day reductions of energy intake in Groups 1 and 2, respectively, during the two-week cereal intervention. This led to comparable mean weight losses (1.91 +/- 0.19 kg-Group 1, 1.37 +/- 0.15 kg-Group 2) that were significantly greater than that observed in Group 3 (0.08 +/- 0.15 kg). The losses were primarily of fat mass. No significant changes of total body water were observed. Weight loss continued during the Volumetric diet in Groups 1 and 2. The changes were comparable to those observed in Group 4, and all were significantly greater than that of Group 3. Self-reported hunger was slightly, but significantly higher than baseline in Groups 1 and 2 during the cereal intervention, but similar to baseline in Groups 1, 2 and 3 during the Volumetric diet. Based on predicted weight loss, compliance with the Volumetric diet was similar and limited in all three intervention groups.'] Does ready-to-eat cereal used as a meal replacement promote weight loss in humans?
