The objective of the study is to show post-prandial benefits of Palaeolithic-type meals as compared to a meal constructed along the lines of the WHO dietary recommendations.

Primary Outcome Measures:
  • Blood glucose [ Time Frame: 0-2 hours ] [ Designated as safety issue: No ]
    positive incremental area under the concentration versus time

  • Plasma insulin [ Time Frame: 0-2 hours ] [ Designated as safety issue: No ]
    net incremental area under the curve

  • Peak blood glucose [ Time Frame: 0-2 hours ] [ Designated as safety issue: No ]
    maximal blood glucose value

Secondary Outcome Measures:
  • Satiety scores [ Time Frame: 0-2 hours ] [ Designated as safety issue: No ]
    area under the curve

  • Gut hormone panel [ Time Frame: 0-3 hours ] [ Designated as safety issue: No ]
    Average concentration over time

Arms Assigned Interventions
Experimental: Palaeolithic-type meal 1 Other: Palaeolithic meal 1
Based on estimated ratios for protein, fat and carbohydrates that are typical of Hunter-Gatherers and does not contain ingredients that were not available in pre-neolithic times
Experimental: Palaeolithic-type meal 2 Other: Palaeolithic meal 2
Based on WHO dietary guidelines for protein, fat and carbohydrate but does not contain ingredients that were not available in pre neolithic times
Placebo Comparator: The reference meal Other: Reference meal
Based on WHO dietary guidelines for protein, fat and carbohydrate.

Detailed Description:

The effects of this set of meals will be assessed with respect to blood

  • blood glucose
  • plasma insulin
  • satiety scores
  • plasma gut hormones It is hypothesised that lower post prandial blood glucose concentration, a lower insulin response and increased satiety will be seen after the Palaeolithic meals compared with a reference meal
