Milk quebra um jejum?
Breaks a fast
Milk quebra o jejum. Fornece calorias significativas ou dispara uma resposta de insulina que encerra o estado metabólico em jejum.
Calorias
~61 kcal per 100 ml (whole milk); ~42 kcal per 100 ml (skimmed)
Por quê — a lógica de caloria e insulina
Milk contains lactose (a sugar), fat, and protein — all three macronutrients. Even a small splash (30 ml) delivers roughly 15–20 kcal plus a measurable insulin response from lactose and the dairy protein leucine, which activates mTOR signalling. This definitively ends a fast.
Isso depende do seu objetivo de jejum?
Milk breaks a fast for every common fasting goal: weight loss (adds significant calories), metabolic health (triggers insulin), and autophagy (mTOR activation from leucine strongly suppresses autophagy). Adding milk to coffee or tea during a fasting window ends the fast.

- Does a splash of milk in coffee break a fast?
- Yes. Even a small amount of milk adds lactose and protein that trigger an insulin response and provide meaningful calories, ending the fast.
