Podcast episode by Dr. Mihail (Mihail Pautov) explaining what sugar (sucrose) is, how it is digested and metabolized, and when sugar is harmful versus useful. Key points: sucrose is a disaccharide of glucose+fructose; intestinal sucrase splits it into absorbable monosaccharides which reach the liver via the portal vein; the liver converts fructose to glucose so circulating sugar appears as glucose; glucose can be used immediately for energy, stored as glycogen (liver ≈100 g, muscle ≈500 g) or, when stores are full, converted to triglycerides and stored as fat. Exercise (especially fasted morning exercise) depletes glycogen, increases glucose uptake independent of insulin, and improves insulin sensitivity. Post-exercise carbohydrate intake accelerates glycogen repletion; recovery of glycogen is slower on ketogenic diets (~~5 days) versus carbohydrate-containing diets (~40 hours noted for the example). Practical advice covers using continuous glucose sensors (sponsored) and tailoring sugar intake to activity level and context.

Questions this episode answers

A disaccharide formed from one glucose molecule bonded to one fructose molecule (50% glucose + 50% fructose).

About 5 grams of sugar per 100 grams of fruit (≈50 g per kilogram).

Liver ≈100 grams of glycogen; muscles ≈500 grams of glycogen (typical stated values).

1 gram of glycogen ≈ 4 calories (kcal).

Approximately 2,000–2,400 calories stored as glycogen in the body (stated estimate).
