What this trial studies
This pilot study investigates the impact of long-term sourdough bread consumption on energy intake and blood lipid levels over a four-week period. Participants, both normal-weight and overweight, will consume sourdough bread as part of their regular diet to assess changes in appetite regulation and body weight. The study aims to determine the feasibility of this dietary intervention and its potential effects on eating behavior. Participants will be monitored for their dietary habits and any changes in their health metrics.
Why it matters
Potential benefit: If successful, this study could provide insights into dietary strategies for managing appetite and body weight.
How similar studies have gone: While this approach is relatively novel, similar dietary interventions have shown promise in managing energy intake and weight.
