Weight-Loss Treatment-induced Physical Activity Associated with Improved Nutrition through Changes in Social Cognitive Theory Variables in Women with Obesity

Behavioral weight-loss treatments have typically been unsuccessful and a theoretical. Even when treatments were scientifically derived, theory has rarely been used to decompose, and understand the bases of, their effects. This 2-year study evaluated mediation of the prediction of nutritional changes...

This 2-year study evaluated mediation of the prediction of nutritional changes by changes in physical activity, through social cognitive theory variables. Data from women with Class 1–2 obesity, classified as “insufficiently active” (N= 50; Mage = 47.6 years), were extracted from 2 initial trials of a new cognitive-behavioral intervention. That treatment sought to improve self-regulation, mood, and self-efficacy through increased physical activity, to then induce improved eating and long-term weight loss.
