postprandial glucose spikes
Post-meal rises in blood sugar. In people with diabetes they clearly matter; the contested part is the popular claim that normal-range spikes meaningfully harm metabolically HEALTHY people — causing fatigue, cravings, inflammation or faster aging — which rests on thin evidence largely extrapolated from diabetic data.

The 4 claims about postprandial glucose spikes
Each keeps its own verdict — we never average them away.
Do sugar spikes make healthy people tired and crash-y?
Insufficient Partly — the post-spike glucose dip does track with hunger and a short-lived rise in fatigue, but "chronic fatigue from spikes" in healthy people is not established.
Do sugar spikes give healthy people brain fog?
Insufficient No good evidence — she herself conceded "there are no studies"; the acute cognitive data in healthy people are small, mixed and often show the opposite.
Do blood-sugar spikes cause PCOS, and can "glucose hacks" reverse it?
Insufficient Low-GI diets modestly improve PCOS symptoms by improving insulin sensitivity, but the causal arrow runs insulin resistance to hyperandrogenism/PCOS, NOT spikes causing PCOS — her direction is reversed.
Does every blood-sugar spike inflame healthy bodies and cause disease?
Refuted A single large glucose load does trigger a transient inflammatory/oxidative blip even in healthy people, but that this scales to systemic chronic inflammation or disease in healthy people is an unproven extrapolation.
