The analysis indicated a significant time effect (p = 0.026) in satisfaction from food in both groups from Week 0 to Week 12. Table Table44 presents body composition data obtained during each of the four testing trials, and Figure Figure11 presents mean changes in body composition data from Week 0 to Week 12.

No clinically significant interactions were seen in metabolic markers, blood lipids, muscle and liver enzymes, electrolytes, red cells, white cells, hormones (insulin, TSH, T3, and T4), heart rate, blood pressure, or weekly reports of side effects. Side effects were recorded on a weekly basis. This shows that the eating desires for both groups were maintained. However, the significant time effect in satisfaction from food found in CF and P suggests that both groups received less enjoyment from the food consumed.
