Abstract
Aims: The purpose of these analyses was to determine the relationship between calcium and caloric intake (as predictors) and weight regain following a weight-loss diet. Methods: In all, 103 women lost weight (M = 9.6 kg) on a meal replacement-supplemented diet over a 6-month period. Caloric intake and calcium intake were both assessed using the Block Food Frequency Questionnaire at 6 months (post-treatment) and at an 18-month follow up. All treatment ended at 6 months. Using change scores from 6 to 18 months, a regression analysis examined the relationship between changes in calcium and caloric intake and weight change (the outcome variable). Results: When tested individually, neither change in calcium intake nor change in caloric intake was associated with change in weight. However, when entered simultaneously, increases in caloric intake predicted increased weight regain and increases in calcium intake predicted decreased weight regain after the diet. Thus, each variable was predictive in the expected direction only when controlling for the other variable (a dual suppressor effect). Conclusions: Increases in caloric intake produce both greater weight gain and higher calcium intake. However, greater calcium may oppose weight gain, canceling out the effect of higher caloric intake. Therefore, when entered singly, neither variable predicts weight change. However, when holding the other variable constant, a positive relationship between caloric intake and weight gain, as well as a negative relationship between calcium intake and weight gain, is revealed.
