Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Recruited participants are checked against the inclusion and exclusion criteria prior the enrollment for the study. Participants are randomly allocated into one of the four treatment groups by computer generated random number conducted by holder of the allocation schedule (Not the trial coordinator).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation is done by block randomisation generating a list of random number in a computer program stratifying by gender.

Efficacy
Statistical methods / analysis
Statistical analysis will be performed by applying appropriate statistical tests using SPSS Inc. software Version 21, p <0.05 will be considered statistically significant. Of note, this is a pilot/ study of 100 participants, comprising 25 in each of the four treatment groups. A drop out rate of 20% or less is expected, this will equate to a minimum expected completion of 20 participants per treatment group which is considered suitable for the exploratory study.

Summary
Brief summary
Quinoa (Chenopodium quinoa) seed is catalogued as a pseudocereal due to the similarity with the cereal family but with a different nutrient composition. Quinoa is a crop related to beetroot and spinach, grown primarily for its edible seeds. Cultivated in the Andean region between Bolivia and Peru, recent interest in this plant has been due to the nutritional value of the seeds in comparison to other cereals. Comparative to other cereals, quinoa is high in protein and rich in antioxidants (Vega-Galvez et al., 2010; Gorinstein et al., 2007). The quinoa seeds are highly nutritious and contain 60% starch and 15% protein. In addition, quinoa is a rich source of anti-oxidants including flavonoids, phenolic acids and squalene. Research has shown a potential role for quinoa in reducing oxidative stress which is increased in response to a high sugar diet (Pasko et al., 2010), and has also been reported to reduce adiposity in response to a high fat diet (Foucault et al., 2012).

We have recently shown quinoa, contributing to 25% of the diet, to significantly increase adiponectin levels in C57BL/6 mouse models of obesity. Several studies have shown the benefits of increased circulating adiponectin particularly in the prevention of cardiovascular diseases, some cases of type 2 diabetes and the Metabolic Syndrome (Hotta et al., 2000; Spranger et al., 2003; Matsuzawa et al., 2004). Whilst body composition did not significantly change, a number of markers of health including lipid profiles were improved. The current study aims to assess the effect of quinoa seeds in varying quantities on adiponectin levels, blood lipid profiles and physical activity and body composition in overweight and obese humans. We hypothesise that inclusion of quinoa in the human diet will increase adiponectin levels and improve blood lipid profile in overweight and obese humans

Participants receive either 25, 50, or 100 grams of quinoa per day for 12 weeks and results compared to a control group (0 grams quinoa/day).
