Brief summary
The effects of two palaeolithic-type meals will be assessed with respect to a panel of gut hormones, satiety, blood glucose and insulin levels as compared to a meal constructed along the lines of the world Health Organisation dietary recommendations
Detailed description
In the current study the effects of two palaeolithic-type meals will be assessed with respect to a panel of gut hormones (including incretins), satiety, blood glucose and insulin levels.
