Introduction: Lipedema is a chronic female disease, characterized by an excessive accumulation of subcutaneous adipose tissue in the limbs and is commonly mistaken for obesity, although the two conditions often coexist. Obesity is associated with increased hedonic hunger and dysfunctional eating behavior. However, these aspects have not been investigated in females with lipedema and obesity. Objectives: The objective of this secondary analysis from a randomized controlled trial was to compare changes in hedonic hunger and eating behavior following two different low-energy diets , low-carbohydrate (CHO) or low-fat, in females with lipedema and obesity. Methods: Females with lipedema and obesity (body mass index (BMI) 30-45 kg/m2) were randomized to two different low-energy diets (1200 kcal), low-CHO diet (LCD) (75 g CHO) or low-fat diet (180 g CHO) for 8 weeks. Hedonic hunger was assessed using the power of food scale (PFS) and eating behavior was assessed using the Dutch Eating Behavior Questionnaire (DEBQ) pre- and post-intervention. Results: A total of 70 females were included with a mean age of 47 years, and a BMI of 37 kg/m2. The LCD group reported a reduction in Food Present (P <0.001) and in Aggregated Score (P = 0.035) from the PFS, while no changes were seen in the low-fat diet group, with changes in Food Present over time being significantly different between groups (P = 0.050). The low-fat diet group reported increases in Restrained Eating from the DEBQ (P = 0.036) while only the LCD group reported decreases in Diffuse Emotions (P = 0.040), however, no differences between groups were found. Conclusion: A LCD may induce more favorable changes in hedonic hunger and eating behavior than an isocaloric low-fat diet in females with lipedema, which may be related to altered metabolic signaling pathways related to satiety and reward.

Background Lipedema is an underdiagnosed condition in women, characterized by a symmetrical increase in subcutaneous adipose tissue (SAT) in the lower extremities, sparing the trunk. The lipedema SAT has been found to be resistant to diet, exercise and bariatric surgery, in regard to both weight loss (WL) and symptom relief. Current experience indicates that a low carbohydrate and high fat (LCHF-diet) might have a beneficial effect on weight and symptom management in lipedema. Objective To assess the impact of an eucaloric low carbohydrate, high fat (LCHF)-diet on pain and quality of life (QoL) in patients with lipedema. Methods Women diagnosed with lipedema, including all types and stages affecting the legs, (age 18-75 years, BMI 30-45 kg/m2) underwent 7 weeks (wk) of LCHF-diet and, thereafter 6 wk of a diet following the Nordic nutrition recommendations. Pain (visual analog scale) and QoL (questionnaire for lymphedema of the limbs), weight and body composition were measured at baseline, wk 7 and 13. Results Nine women (BMI: 36.7±4.5kg/m2 and age: 46.9±7 years) were recruited. The LCHF diet induced a significant WL -4.6±0.7 kg (-4.5±2.4%), P<0.001 for both, and reduction in pain (-2.3±0.4 cm, P=0.020). No correlation was found between WL and changes in pain at wk 7 (r = 0.283, P = 0.460). WL was maintained between wk 7 and 13 (0.3±0.7 kg, P=0.430), but pain returned to baseline levels at wk 13 (4.2±0.7 cm ,P=0.690). A significant increase in general QoL was found between baseline and wk 7 (1.0 (95% CI (2.0, 0.001), P=0.050) and 13 (1.0 95% CI (2.0, 0.001) P=0.050), respectively. Conclusion A LCHF-diet is associated with reduction in perceived pain and improvement in QoL, in patients with lipedema. Larger randomized clinical trials are needed to confirm these findings.

Background Lipedema is considered an inflammation-related disease, and low-carbohydrate ketogenic diets may help reduce inflammation. However, no randomized controlled trials have investigated the effect of a low-carbohydrate ketogenic diet on inflammatory markers in females with lipedema. Objectives To compare changes in inflammatory and fibrosis-associated markers after a low-energy low-carbohydrate diet (LCD) compared with a low-fat diet in females with lipedema, and to explore potential associations between changes in pain and changes in inflammatory and fibrosis-associated markers. Methods Females with lipedema and obesity were randomly assigned to either an LCD or low-fat diet (both 1200 kcal/d) for 8 weeks. Body composition [fat mass (FM) and fat-free mass] and the plasma concentrations of high-sensitivity C-reactive protein (hsCRP), cytokines, and fibrosis-associated markers were measured pre- and postintervention. Results A total of 70 females were included (35/group) (mean age: 47.3 ± 10.9 y, BMI: 36.9 ± 4.9 kg/m2). Both groups lost weight and FM (kg and %), with a greater reduction in the LCD group. A reduction in macrophage inflammatory protein-1ß, tumor necrosis factor-α, and hsCRP was seen in the LCD group only, despite no significant differences between groups. No associations were found between changes in pain and changes in cytokines and fibrosis-associated markers. Conclusions Changes in cytokines and fibrosis-associated markers did not differ between low-energy LCD and low-fat diets in females with lipedema, despite a beneficial profile in the LCD group. Inflammation does not seem to be involved in pain reduction following LCD in this patient group. Trial registration number This trial was registered at clinicaltrials.gov as NCT04632810.
