Objective Daily self‐weighing is an effective weight loss strategy. Little is known about “micro” factors influencing nonadherence to self‐weighing (e.g., daily overeating). It was hypothesized that increased caloric intake on a given day would increase odds of not self‐weighing the following day. Methods Daily self‐reports of weight and caloric intake were collected from 74 adults with overweight and obesity (mean BMI = 31.2 ± 4.5 kg/m 2 , age = 50.6 ± 10 years, 69% female, 87% Caucasian) throughout a 12‐week Internet‐based weight management intervention. Multilevel logistic regression investigated odds of nonadherence to self‐weighing on a given day based on the previous day's caloric intake. Results Self‐monitoring adherence was high (weights: 87%; calories: 85%); adherence was associated with greater 12‐week weight loss (weighing: r = −0.24, P = 0.04; calories: r = −0.26, P = 0.04). Increased caloric intake on a given day, relative to the individual's average intake, was associated with increased odds of nonadherence to self‐weighing the next day ( F (1,5106) = 12.66, P = 0.0004, β = 0.001). For example, following a day of eating 300 calories more than usual, odds of not self‐weighing increased by 1.33. Conclusions Odds of nonadherence to self‐weighing increased following a day with higher‐than‐usual caloric intake. Weight management interventions collecting daily self‐monitoring data could provide support to participants who report increased caloric intake to prevent self‐weighing nonadherence.
