Greater intrinsic motivation for engaging in healthy lifestyle behaviors is associated with reduced postpartum weight.
Article in Obesity (Silver Spring, Md.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveLifestyle behaviors impact postpartum weight, yet intrinsic motivation for them-i.e., what individuals enjoy, value, and do with ease-is poorly understood. The Pregnancy, Lifestyle and Environment Study-2 (PETALS-2) examined whether intrinsic motivations for engaging in healthy eating, physical activity, and weight self-monitoring are each associated with long-term postpartum weight change.
methodsWe assessed behavior-specific intrinsic motivation using validated scales, from pregnancy up to six time points through 30 months post partum, among diverse cohort participants (N = 311) in a large health care system. Weight was prospectively ascertained via electronic health records, remote scales, and study visits.
resultsIn adjusted regressions, participants with higher intrinsic motivation experienced significantly reduced postpartum weight. For healthy eating motivation, each one-unit-higher score predicted up to -3.43 lb (95% CI: -5.34 to -1.53) postpartum weight at 24 months; for physical activity motivation, -2.70 lb (95 CI: -4.61 to -0.78) at 30 months; for self-weighing motivation, -4.15 lb (95% CI: -6.33 to -1.97) at 30 months; and, for a combined motivation score across all three behaviors, -5.47 lb (95% CI: -7.95, -2.99) at 24 months.
conclusionsGreater intrinsic motivation for healthy lifestyle behaviors predicted reduced long-term postpartum weight and could be a promising target for innovative behavioral interventions.
