Replacing one daily carbohydrate serving with cruciferous vegetables significantly reduced fat mass and improved metabolic health in individuals with obesity and metabolic dysfunction-associated steatotic liver disease (MASLD). This simple dietary change offers a pragmatic approach to improving body composition and liver health.
Area of Science:
- Metabolic health and nutrition science
- Gastroenterology and hepatology
- Obesity research
Background:
- Metabolic dysfunction-associated steatotic liver disease (MASLD) is linked to obesity and insulin resistance.
- Dietary interventions are key for MASLD management, but adherence can be challenging with complex or calorie-restricted diets.
- A simple dietary modification strategy was investigated for its effects on body composition and metabolic parameters in MASLD patients.
Purpose of the Study:
- To evaluate the impact of substituting one daily carbohydrate serving with cruciferous vegetables on body composition and metabolic parameters in adults with obesity and MASLD.
- To explore the associations between changes in fat mass and levels of vitamin D and follistatin.
- To assess the feasibility and potential benefits of a pragmatic, short-term dietary intervention.
Main Methods:
- A prospective pilot study involving 44 adults with obesity and MASLD.
- A two-month intervention replacing one daily carbohydrate serving with 200g of cruciferous vegetables, without calorie restriction.
- Measurements included anthropometrics, bioimpedance, biochemical markers, and FibroScan at baseline and post-intervention, analyzed using Wilcoxon signed-rank test, Spearman's correlation, and GEE models.
Main Results:
- A significant reduction in fat mass (average 12% decrease) was observed post-intervention.
- Improvements in metabolic and hepatic parameters were noted.
- Fat mass reduction was inversely correlated with changes in fat-free mass and vitamin D levels.
Conclusions:
- A straightforward dietary substitution of carbohydrates with cruciferous vegetables, without calorie restriction, improved body composition and metabolic health in individuals with obesity and MASLD.
- This pragmatic dietary modification shows potential for clinically meaningful benefits and supports minimal dietary substitution strategies.
- Further confirmation in larger randomized controlled trials is needed due to the pilot design.
