Behavioural and Neurological Effects of Fructose Cessation and Reexposure
Bibliographic record
Abstract
Fructose is a monosaccharide present in many healthy and unhealthy food items consumed.Fructose consumption has risen over the years, which has been linked to the development of metabolic syndrome, non-alcoholic fatty liver disease, and obesity.Detrimental metabolic impacts of fructose consumption include increased feeding behaviour, body weight gain, and adiposity, among other hallmarks of metabolic distress.The hypothalamus is a brain region mediating feeding behaviour, such as promoting feeding via the NPY/AgRP neurons of the arcuate nucleus (ARC).Recent evidence shows that fructose can act via the hypothalamus to produce a shift towards positive energy balance, and preliminary findings from our lab have shown that fructose consumption produces an obesogenic phenotype and increased excitatory tone onto NPY/AgRP neurons.While this tone is reversible with cessation after one-week of fructose consumption, it has not been determined if increased excitatory tone onto NPY/AgRP neurons is reversible with cessation from chronic fructose consumption.We used a combination of whole-cell patch-clamp recordings and a fructose choice test to assess how cessation of dietary fructose could reverse fructose-mediated increases in excitatory tone at NPY/AgRP neurons or enhance fructose preference upon re-exposure.We have found that fructose abstinence reverted increases in excitatory tone at NPY/AgRP neurons in males, but not females.Additionally, fructose consumption reduced the preference for fructose, which was re-established with a fructose cessation.These findings suggest that maintenance of increased excitatory tone despite fructose cessation may drive feeding behaviour.Additionally, repeated exposures to fructose could enhance preference, which may predispose individuals to consume increased sugars later in life.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
