Bricht Alcohol ein Fasten?
Alcohol bricht ein Fasten. Es bietet bedeutungsvolle Kalorien oder löst eine Insulinreaktion aus, die den nüchternen Stoffwechselzustand beendet.
Kalorien
~100–150 kcal per standard drink (7 kcal/g of ethanol)
Warum — die Kalorien- und Insulinlogik
Alcohol provides 7 kcal per gram — second only to fat. A standard drink (12 oz beer, 5 oz wine, 1.5 oz spirits) delivers 100–150 kcal. Ethanol is a priority fuel that the liver processes before fat, effectively halting fat oxidation while it is being metabolised. It also disrupts sleep quality, which can compound the hunger effects of fasting.
Hängt es von Ihrem Fastenzielem ab?
Alcohol breaks a fast for every common fasting goal: it adds significant calories (weight loss), halts fat oxidation (metabolic health), and strongly suppresses autophagy. Drinking alcohol in the fasting window also increases the risk of hypoglycaemia for anyone predisposed, particularly if they have not eaten in many hours. Alcohol is best kept to the eating window, in moderation.
