Does coffee break a fast?
Black coffee practically does not — the problem is milk and sugar. A latte carries energy, and that breaks the fast.

By the energy rule, black coffee practically does not break a fast: it is essentially calorie-free, and the caffeine genuinely helps with the hunger that peaks and passes in the first days. Plain tea without sugar is in the same class.
What breaks it: milk or cream in the coffee, sugar, honey, and "just a splash" of anything with energy. A latte carries around 200 kcal — energy, not a grey area. If the point is only timing, a "wet fast" is no big deal; if the goal is a deficit, every latte counts.
In the fasting window: water, black coffee, tea without sugar. And if you are unsure whether fasting is for you — pregnancy, a history of eating disorders, diabetes medication and some medical conditions mean talking to a doctor first.
