Interaction between treatment group and participants’ energy intake change when predicting spousal weight loss. High and low calorie reduction are defined as ±1 SD from the mean reduction score of 546.62 kcal. “High reduction” thus corresponds to a reduction of 1295.14 kcal, and “low reduction” corresponds to a gain of 201.90 kcal.
