Clinical or cultural? Dietary interventions for lipedema: a systematic review

Lipedema is a chronic, progressive condition characterized by symmetrical accumulation of adipose tissue, predominantly in women's lower extremities. It is frequently associated with pain, reduced mobility, and psychological distress. Dietary interventions have become central to conservative management of the condition, yet their clinical efficacy remains unclear.

This systematic review included peer-reviewed studies assessing dietary strategies in individuals with clinically diagnosed lipedema. Searches were conducted in four databases in July 2025, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eligible studies applied dietary interventions and reported clinical or psychosocial outcomes, and the risk of bias was subsequently assessed.

Nine studies involving 269 women met the inclusion criteria. The majority applied hypocaloric dietary protocols, particularly ketogenic, low-carbohydrate high-fat, or ketogenic modified Mediterranean diets. Across studies, weight loss and reduction in fat mass were consistently reported. Some studies also observed improvements in pain, inflammation, and quality of life, though these outcomes were not uniformly assessed. Few studies used advanced measures of body composition such as dual-energy X-ray absorptiometry or magnetic resonance imaging; most relied on bioelectrical impedance analysis. Only one study evaluated emotional dysregulation and only one assessed food addiction, but no study systematically measured eating behavior traits, or current or past eating disorders. Intervention durations ranged from four to twenty-eight weeks, and adherence strategies varied. The risk of bias was moderate to high in most studies. Two trials (conducted by Lundanes and Jeziorek et al.) were randomized controlled trials, whereas the remaining studies used non-randomized designs despite including control and intervention groups. Due to the high heterogeneity in study design, outcomes, and measurement tools, combined with the small sample sizes and risk of bias, it was not possible to conduct a meta-analysis.

The effects of dietary approaches on lipedema remain unclear. Future studies should adopt robust methodological designs, include larger and stratified samples based on disease stage, use accurate assessments of body composition (including muscle mass and strength), evaluate mental health and eating behaviors, and investigate the long-term sustainability of interventions. The literature lacks standardized methodologies and comprehensive evaluation of psychosocial and eating behavior, highlighting the need for stronger evidence to inform clinical practice.
