Figure 1

Body weight gain in obesity-prone (●) and obesity-resistant (○) Sprague Dawley rats fed differing levels of resistant starch (RS) for 4 wk. Body weight gain is corrected body weight as calculated by the following formula; (final body weight – full caecum weight) – initial body weight. Values are expressed as mean ± SEM. There was a significant interaction between RS and phenotype (P < 0.05). A significant difference in comparison to 0% RS is denoted by (*) for obesity prone rats and (#) for obesity resistant rats, P < 0.05. Dietary treatment groups were comprised of a total of 16 animals; n=8 obesity prone and n=8 obesity resistant.
