Abstract: The proportion of people with obesity in our society continues to increase. This situation had led to the development of numerous weight management approaches. The majority of these approaches involve both caloric restriction and cognitive dietary restraint in order to promote weight management. However, long-term success of these methods remains relatively low. While some authors value the importance of cognitive dietary restraint, its long-term effectiveness has also been questioned considering the high failure rate in weight management strategies. Furthermore, the isolated impact of cognitive dietary restraint has not been clearly investigated since the majority of studies performed to date have always been conducted in traditional intervention contexts where caloric restriction and cognitive dietary restraint are both present. The results presented in this master thesis therefore highlight the importance to focus on this issue. Thus, women provided with a satiating low energy density diet corresponding to 85% of their energy needs and assigned to a condition favoring or not an increase in cognitive dietary restraint did not show any difference in their eating behaviors. In both groups, disinhibition, hunger, craving and perceived stress all decreased in response to a controlled intervention as at the three-month follow-up. No significant differences were found in appetite sensation as evaluated with a standardized breakfast following the intervention. The present results suggest that a slight increase in CDR has no negative impact on factors regulating energy balance in the context of energy restriction.
