AI synopsis

What people are saying

Discussions consistently highlight the stability of gluconeogenesis, with many posters quoting or summarizing the paper's findings, such as its resistance to perturbation even during fasting or high-protein intake. The tone ranges from agreement to curiosity, reflecting deep engagement and recognition of the research's significance.

AgreementModerate agreement

Most discussions support the idea that gluconeogenesis remains relatively stable across various conditions, with several posts emphasizing this consistency.

InterestHigh interest

The community shows high interest, with many engaging deeply by referencing specific studies and physiological mechanisms.

EngagementHigh engagement

Posts analyze, debate, and reference multiple sources, indicating active and detailed engagement with the research.

ImpactModerate impact

The discussions influence understanding of metabolic processes and could inform dietary or medical approaches, suggesting moderate to high impact.

Abstract in brief

  • The review discusses how the process of gluconeogenesis (the production of glucose in the liver) is generally stable and constant in healthy individuals, even under different metabolic conditions, but it’s uncertain if this stability holds true for people with diabetes.
  • The authors highlight that the rate of glucose appearance in the blood can change, but the actual rate of gluconeogenesis stays remarkably steady, and the mechanisms behind this regulation are not fully understood.
  • They also suggest that in cases of excess substrates, different gluconeogenic substrates might substitute for each other depending on what's available, which could help keep the overall glucose production relatively unchanged, but this idea needs more research for confirmation.]

@AKoutnik @ProfTimNoakes @vermeulen_emiel @PhilipPrins11 I would completely agree. Also that most changes in hepatic glucose production are from changes in glycogenolysis rather than gluconeogenesis https://t.co/7krzK7TeaB

Pretty compelling review that the rate of GNG is generally hard to perturb. Even diabetic physiology and starvation hardly budge it. I'd guess extremely high protein intake also wouldn't do much. CC @KetoCarnivore https://t.co/jUhYGRPTqS https://t.co/iY6EWPq9Tg

@anti_wokeist According to this paper, following a fast of 40 hours lactate contributes 92% to GNG. Don't know how similar the situation would be for a ketogenic diet. https://t.co/lNc8nrc2sX

@BillOccham @MacroFour @raphaels7 @KevinH_PhD @HermanPontzer Yes. It should be noted that GNG will be happening at a similar rate even outside of fasted conditions. It's probably why extra glucose is available longer than might be expected from a naive analysis. https://t.co/jUhYGRPTqS

@rf121rf @BreezyEvergreen @CarnivoreAugust @richcollins Well you're wrong then as GNG happens even in the high carb context. https://t.co/lNc8nrc2sX

@upyrbike @LowCarbEP @MHS_tweeting It may not be exactly fixed but multiple studies I have read come out at a pretty similar value. https://t.co/h8yT0EMQj4

@MigraineBook @richcollins @nicknorwitz @HermanPontzer No. GNG is hard to perturb markedly, probably because the organism relies on a near-constant rate of glucose production to avoid deadly shortages. https://t.co/jUhYGRPTqS
