You've Been Lied to About Sugar & Alzheimer's

A single blood sugar spike after eating grapes on a ketogenic diet reflects temporary physiological insulin resistance, not fruit being harmful — slowly reintroducing whole fruits over weeks will normalize the response.

Key takeaways

Low-carb dieters: reintroduce fruit gradually over days, not all at once

Low-carb dieters: reintroduce fruit gradually over days, not all at once

  • Physiological insulin resistance from low-carb causes temporary glucose spikes; resolves after days of carb intake
  • Gut microbiome needs slow adaptation to fermentable carbs to avoid bloating/gas

CGM glucose spikes mislead low-carb dieters into avoiding healthy carbs

CGM glucose spikes mislead low-carb dieters into avoiding healthy carbs

  • Normal physiological insulin resistance after ketogenic diets causes elevated post-meal glucose readings
  • This temporary adaptive response is not pathological or evidence of harm

Alzheimer's pathology linked to low brain glucose use, not high blood sugar

  • Reduced glucose uptake and metabolism in the brain correlates with more tau and amyloid-beta accumulation
  • Brain hypometabolism is a fundamental feature of Alzheimer's disease

Researcher Exposes The Truth About Fructose & Glycation

Don’t avoid fruit or fruit juice due to glycation fears — fructose appears in blood at levels 200x lower than glucose, gets rapidly metabolized, and fructose-containing foods have compounds that actually reduce glycation.

Sugar Diet Cope from the Low-Carb "Experts"

High-carb, low-fat diets improve insulin sensitivity and drive weight loss even in obese and type 2 diabetic populations, as demonstrated by the Kempner rice diet and Pritikin studies — making the low-carb claim that carbs inherently cause metabolic dysfunction unsupported.

Ep. 132: You've Been Lied to About Fructose

Fructose is not uniquely toxic — at least 90% is converted to glucose, lactate, and glycogen rather than fat, making fruit, juice, and honey safe carbohydrate sources for liver and metabolic health.

The Secret to Stabilizing Blood Sugar WITH Carbs

If carbs cause blood sugar crashes, pair them with protein, fat, and fiber to slow absorption — but if you tolerate grains poorly, switching to fruit-based carbs may resolve the issue entirely without eliminating carbs.
