Brief Summary

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

The goal of this mechanistic, exploratory study is to compare the effectiveness of Oligomalt to Glucidex 40 after eating in adults with Type 2 Diabetes (T2D) and in otherwise healthy adults with overweight or obesity (HAO).

Detailed Description

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

The main question it aims to answer is how consumption of Oligomalt, a slowly digestible carbohydrate, will reduce glucose and insulin spikes in adults with T2D and in HAO relative to Glucidex 40.
