TLDR
It is illustrated that WL + PA can be effective in improving older adults’ self-efficacy for the self-regulation of eating behavior and that these changes are prospectively related to the amount of weight loss.
Abstract
Objectives. Using the weight efficacy lifestyle questionnaire (WEL), we examined whether a group-mediated inter vention for weight loss among older, obese adults resulted in changes in self-regulatory self-efficacy for eating behavior and whether these changes mediated weight loss. Methods. This was a randomized controlled design, and 288 older adults received 1 of 3 treatments for 6 months: physical activity only (PA), weight loss + physical activity (WL + PA), or a successful aging (SA) health education program. The WEL was administered prior to randomization and again at the 6-month follow-up visit. Results. A significant treatment effect was observed for the WEL, F (2,249) = 15.11, p < .0001, partial eta 2 = .11, showing that improvement occurred only in the WL + PA group as compared with PA and SA. Changes in WEL scores partially mediated the effects of the WL + PA intervention on weight loss. Discussion. These results illustrate that WL + PA can be effective in improving older adults’ self-efficacy for the selfregulation of eating behavior and that these changes are prospectively related to the amount of weight loss. Further research is warranted on an expanded concept of self-efficacy as well as controlled experimental studies on eating behavior in older adults.

Transtheoretical model stages of change for dietary and physical exercise modification in weight loss management for overweight and obese adults

TL;DR: The evidence to support the use of TTM SOC in weight loss interventions is limited by risk of bias and imprecision, not allowing firm conclusions to be drawn, and very low quality evidence that it might lead to better dietary and physical activity habits is found.

A systematic review of single health behavior change interventions vs. multiple health behavior change interventions among older adults

TL;DR: Evaluated SHBC interventions vs. multiple health behavior change interventions among older age individuals revealed that interventions were the most common and showed the most promise in influencing positive outcomes in physical activity behavior among community-dwelling older adults.

Comparison of the Atkins, Ornish, Weight Watchers, and Zone diets for weight loss and heart disease risk reduction: a randomized trial.

TL;DR: Overall dietary adherence rates were low, although increased adherence was associated with greater weight loss and cardiac risk factor reductions for each diet group, and each popular diet modestly reduced body weight and several cardiac risk factors at 1 year.
