Effective Weight Loss: An Acceptance-Based Behavioral Approach: Workbook

Effective Weight Control: An Acceptance-Based Behavioral Approach comes in two volumes. This page is for the Workbook. Click here to access the Clinician Guide.

Effective weight control provides a scientifically validated solution to the challenge of sustainable weight control. With over two-thirds of U.S. adults classified as overweight or obese, the health risks of excess weight, including heart disease and diabetes, are significant, yet long-term weight loss remains difficult to achieve. This book introduces acceptance-based treatment (ABT), an innovative approach that builds on cognitive and behavioral principles while incorporating acceptance-based strategies to address the psychological and emotional barriers to weight management. By fostering psychological flexibility, ABT helps individuals make health-conscious, values-driven decisions even in the face of cravings or discomfort. Research shows ABT leads to greater and more lasting weight loss compared to traditional treatments, particularly for those prone to emotional eating or food cue reactivity. Combining proven behavioral tools like self-monitoring with strategies such as mindful decision-making and acceptance, this program offers a practical framework for achieving and maintaining meaningful weight loss. Ideal for clinicians and individuals alike, this book delivers a structured, evidence-based approach to lasting success.

Introduction & Theoretical Background

Weight control is a significant health concern, with over two thirds of adults in the United States classified as overweight or obese. Obesity increases the risk of heart disease, diabetes, cancer, and reduced quality of life. Even a modest 5% weight loss can improve health markers like blood pressure, glycemic control, and cholesterol levels (Goldstein, 1992). However, sustaining weight loss is difficult. While diet programs can lead to short-term results (3–6% weight loss at 12 months; Tsai & Wadden, 2005), fewer than 20% of participants maintain a 10% weight loss after one year. The modern environment, filled with calorie-dense foods and sedentary habits, makes lasting weight control particularly challenging.

Cognitive-behavioral treatments (CBTs) for weight loss focus on calorie tracking, portion control, and exercise planning, offering important tools for weight management. However, these methods often fall short because they don’t address the psychological and emotional drivers of eating behavior. Many individuals

Therapist Guidance

Each Treatments That Work® title is published as part of a pair:

  • Clients use the Workbooks which contain elements of psychoeducation, skills development, self-assessment quizzes, homework exercises, and record forms.
  • Clinicians use the Clinician Guides which contain step-by-step instructions for teaching clients skills and overcoming common difficulties.

Although written for the client, the exercises in the workbook are intended to be carried out under the supervision of a mental health professional. The authors suggest that the most effective implementation of these exercises requires an understanding of the principles underlying the different procedures, and that mental health professionals should be familiar with both the Clinician Guide as well as this Workbook. 

 Therapists with an active subscription to a Psychology Tools ‘Complete’ plan are licensed to use Treatments That Work® titles, and to download and share chapters with their clients.
