Obesity is a significant health concern, particularly for individuals with serious mental illnesses. This article delves into the effectiveness of the RENEW weight loss intervention, analyzes factors influencing its success, and explores alternative weight loss programs.
Obesity and Mental Illness: A Complex Relationship
Individuals with schizophrenia and other serious mental illnesses, especially women, face higher rates of obesity compared to the general population. This increased prevalence of obesity is associated with several negative consequences, including:
- Greater severity of psychiatric symptoms
- Decreased level of functioning
- Poorer quality of life
- Increased risk of cardiovascular disease, the most common cause of death in this population
Several factors contribute to the elevated risk of obesity in individuals with serious mental illness:
- Inadequate Medical Care: Current healthcare models often fail to address the co-morbid medical conditions of individuals with schizophrenia. They are less likely to receive standard treatments for cardiovascular conditions, despite being at higher risk.
- Lifestyle Factors: Individuals with schizophrenia tend to consume more sugar and fat and engage in less physical activity than the general population. Sedentary behavior is also a significant issue.
- Psychotropic Medications: Second-generation antipsychotics, while beneficial for managing mental health symptoms, are often associated with weight gain, although the risk varies among different medications.
The RENEW Weight Loss Intervention: A Comprehensive Analysis
The Recovering Energy through Nutrition and Exercise for Weight Loss (RENEW) intervention is a behavioral weight loss program designed for individuals with serious mental illness. The program combines evidence-based weight loss strategies with psychiatric rehabilitation principles, focusing on modifying nutrition and physical activity.
Study Design and Participants
A study involving 136 individuals with serious mental illness from four different community mental health programs was conducted to assess the effectiveness of the RENEW intervention. Participants met the following inclusion criteria:

- Confirmed diagnosis of serious mental illness
- Age between 18 and 65
- BMI ≥ 25
- Medication stability (no changes in antipsychotic medications or mood stabilizers for the last 3 months)
Individuals with intellectual disability, dementia, eating disorders, or severe cardiovascular or other physical illnesses that would limit participation in physical activity were excluded. Participants were randomly assigned to either the RENEW intervention group or a control group receiving treatment as usual.
Intervention Components
The RENEW program was divided into three phases:
- Intensive Intervention (Weeks 1-12): Participants attended weekly 3-hour group sessions and had the opportunity to participate in group-based exercise sessions twice a week. They were given an individual calorie goal (500 kcal caloric restriction) and two meal replacements per day. This phase emphasized knowledge and skill acquisition, with specific information about nutrition and physical activity, and intensive social support.
- Maintenance Phase (Weeks 13-24): This phase included a 3-hour monthly session, one-hour exercise sessions twice a week, weekly phone calls for problem-solving and goal setting, and a weekly newsletter with tips and encouragement. The emphasis was on transferring behavioral changes into habit patterns and identifying problematic eating and activity patterns. Social support remained a key component.
- Intermittent Supports (Weeks 25-52): Participants received feedback, reminders, and support to continue adhering to the behavioral changes achieved during the earlier phases, without face-to-face contact.
Results and Outcomes
The intervention group experienced a modest weight loss of 4.8 lbs at 3 months and 4.1 lbs at 6 months. However, they regained some weight during the intermittent supports phase, resulting in a slight weight gain of 1.5 lbs at 12 months. In contrast, the control group gained a total of 6.2 lbs at 12 months.
The Impact of Setting: Responders vs. Non-Responders
Interestingly, the study revealed that the setting in which participants received mental health services significantly impacted their response to the intervention. Two of the intervention sites (both in urban Kansas City) showed a pattern of weight loss at all three time periods, with a mean weight loss of 10 lbs and 6.6 lbs at the 12-month follow-up, respectively. These sites were labeled "responders." Conversely, the other two sites (one in suburban Kansas City and one in Las Vegas) gained weight at most time points, with an overall mean weight gain of 18.6 lbs and 3.6 lbs, respectively, at the 12-month follow-up. These sites were labeled "non-responders."
Further analysis revealed no significant differences between the four sites in terms of age, gender, education, BPRS scores, baseline body weight, or medication risk. However, there was a difference in race, with a greater proportion of African Americans at the responder sites.

Implications and Considerations
The RENEW study highlights the potential of behavioral weight loss interventions for individuals with serious mental illness. However, the modest weight loss achieved by the intervention group as a whole underscores the challenges of promoting sustainable weight loss in this population. The significant differences observed between the responder and non-responder sites suggest that environmental factors and the level of ongoing support play a crucial role in the success of weight loss programs. The concept of the obesogenic environment, which refers to environments that promote obesity, deserves further examination as a factor in the success of weight loss programs.

Pros
- Emphasis on Whole Foods: Encourages a diet rich in unprocessed foods like meat, fish, poultry, and vegetables, which are often lower in calories and rich in nutrients.

- Flexible and Easy to Follow: Does not require calorie counting or strict macronutrient tracking, and offers options for paleo, keto, vegan, and vegetarian diets.
Cons
- Lack of Scientific Evidence: The idea of seven specific female hormone types is not backed by scientific evidence.
