Energy balance
Behavioral interventions involving caloric restriction, dietary restructuring, and moderate-intensity physical activity are effective in reducing weight and preventing further weight gain in patients with schizophrenia.
Start with small, manageable changes: reduce calories by 500-750 per day, eat more fiber and less fat, and aim for 24 minutes of moderate exercise daily. Consistency is key, and working with a professional who understands schizophrenia can help overcome executive function challenges.
GoodSupportsHIGH confidence
The management of weight gain and obesity in patients with schizophrenia centers on behavioural interventions using caloric intake reduction, dietary restructuring, and moderate-intensity physical activity.
Why this rating
Supported by multiple controlled studies and meta-analyses, though long-term adherence can be challenging.

- Second-generation antipsychotics, particularly clozapine and olanzapine, cause significant weight gain in patients with schizophrenia, driven by increased caloric intake (orexigenic effects) and potentially altered energy expenditure.Strong
- Metformin is the most effective pharmacological adjunct for treating antipsychotic-induced weight gain, resulting in significant weight loss compared to placebo.Strong
