Measure
Pulse Fibre
The intervention group will receive a biscuit containing 5g/serving of yellow pea fibre to be eaten 3 times per day approximately 30 minutes prior to their 3 largest meals. Pulse fibre: Yellow pea hull fibre incorporated into a biscuit at 5 g/serving.
Control
The placebo group will receive a biscuit an isocaloric control biscuit that is similar in taste and texture and without pulse fibre to be eaten 3 times per day approximately 30 minutes prior to their 3 largest meals. Control: Control biscuit with no yellow pea hull fibre.

OTHER_PRE_SPECIFIED outcome

Timeframe: 12 weeks

Gut microbiota alpha diversity measured at 12 weeks as Chao index. Chao index is an abundance-based estimator of species richness within a sample. There are no preset minimum and maximum values but scores typically range from 0 to 4000. A higher score is generally regarded as better.

OTHER_PRE_SPECIFIED outcome

Timeframe: 12 weeks

Serum metabolomics measured at 12 weeks using 1H-NMR analysis. Principal component analysis is used to see if two or more groups of samples separate into distinct clusters. The principal components generated in this analysis range from 0-100%. A higher value means that more variability among the samples is explained by this principal component.
