It's funny that skipping break-fast is considered not fasting.
I think this thing that we do (we have to eat every four hours or we will die) has nothing to do with the normal state of affairs for most of human history;
And I'm not talking only about the palaeolithic here, but my grandparents time also.
Because the three meals a day mantra and "breakfast is the most important meal" is hype to sell more cereal, eggs, and milk. Skipping breakfast isn't fasting if you aren't hungry.
Sleeping is fasting, that's why the first meal of the day is called break/fast. It only takes about 6-8 hours for food to be digested, when you aren't digesting, you're fasting. Skipping a meal is fasting, doesn't matter if you're hungry or not, if you aren't digesting, you're fasting.
