Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To our knowledge, no study has yet reported the short and long-term impacts of a HAES approach on a cluster of variables (psychological, morphological, metabolic, and nutritional) in women. The aim of this study is to measure the effects of a HAES approach on global health status of premenopausal overweight women preoccupied about their weight and who have been unsuccessful in previous weight loss attempts. In this parallel controlled trial, women will be randomized to one of the 3 treatment conditions: HAES group, Social support group (SS), or Control group. Measurements will be taken in the short term as well as in the long term (up to 1 year post-intervention).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Health-At-Every-Size (HAES)
Health-At-Every-Size (HAES)
1. HAES group: 14 weekly sessions.
Focus on general well-being and positive ways of having a healthy and satisfying lifestyle. Supported by lectures, guided self-reflection, group discussions, as well as practical exercises, this intervention aims at enhancing awareness and knowledge about biological, psychological, and sociocultural aspects of body weight.
2. SS group: 14 weekly sessions.
The objective is to reproduce a structural social support provided by the group itself. Each participant offers their support to each other. Each theme discussed in the HAES group is repeated in the SS group but the health professionals in charge of the group (dietitian \& psychologist) are not counselors (as in HAES group) but only facilitators.
Outcome measures: For all women under study.
