Breakfast makes me drowsy and less productive and it has always been this way. When I forced myself to eat in the mornings and/or five times a day, it was horrible. Brain fog, overall laziness and I felt like shit all the time.
Then I moved to not eating in the morning. Just water and coffee with no additions. Ate mostly in the evening and all was good. Then I read that the last meal should be about 2 hours before sleep. Ok.
And then I read about intermittent fasting which... I've already been on unknowingly. And so am to this day. The feeling of hunger only exists after I eat something. If I don't eat before evening, I'm not hungry and could go to sleep without eating. But if I eat some snack during the day, I'm hungry since the first dish.
