A research article titled “Running on empty: the effects of food deprivation on concentration and perseverance” showed how food deprivation affects concentration and perseverance, and aimed to analyze our ability to focus, in spite of the internal and external factors that influenced our cognitive capabilities.
One of the theories that prompted research is the glucostatic theory; building on the logic that glucose increases concentration because it is the brain’s primary fuel. More or less Delancy and Solberg; the authors of the article, mentioned that the earliest investigations correlated negative feelings, biological deficiencies and poor cognitive abilities with either long-term (36 hours and longer) food deprivation or fasting for several days. Further findings shed some light on four discoveries of why past research was not concise with the current hypothesis in the research article, and according to some researchers, most of the results so far indicate that cognitive function is not affected significantly by short-term fasting.
The participants in the study were expected to rate from weak to strong regarding their mental concentration based on a time period of 24, 12-hour or no food deprivation at all. And some participants were excluded to prevent the study from being jeopardized. The methodology used was by supplying an online numbers-matching test that consisted of 51 volunteers, and scoring was calculated by percentage. After submitting the informed consents the participants were given a set of rules to abide by while taking the test, to prevent within-group influence.
Although the effect of gender was not found, the research paper presented some difficulties that led several of the
