Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate the effects of a fibre mixture added to a high-protein diet on metabolic, gut and brain health.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The fibre mixture that will be investigated is hypothesized to improved metabolic, gut and brain health. It potentially increases insulin sensitivity, satiety, gut barrier function, improves food-reward related brain activity and decreases inflammation, gut permeability, and ectopic lipid accumulation, among other potential health effects.

The fibre mixture will be administrated during 12 weeks combined a high-protein diet. The placebo-controlled parallel design of the study allows for a placebo group to use maltodextrin combined with a high-protein diet for 12 weeks. The high-protein diet is known to increase satiety and might enhance the difference between the intervention and placebo groups in terms of outcome measurements. The potential health effects as described earlier will be investigated using different techniques.
