I'm sorry, but you've collected no data, only noise. Eating rice for 2 weeks would have produced similar effects. As to your subjective experience – it's probably 100% placebo.

If you want to call something an experiment, you should know how to conduct an experiment in that respective field. Your experiences only show how a product like Soylent induces magical thinking in its consumers.

If you want to produce a single data point with Soylent (that would hardly be relevant, as it would be a sampling size of one, but still, it would be one sampling of data rather than zero), eat nothing but Soylent for at least 6 months.
