As you have seen, garlic must be consumed raw, or on an empty stomach in the morning, otherwise in the evening. The reason why it must be consumed raw is that  the properties of allicin only remain perfect  in this condition.

Indeed, if it is cooked, allicin loses the effectiveness of its properties. If you want to eat just the garlic, the best way to do this is to  remove the clove  and  lightly press it with a knife to crush it.

Grinding promotes greater availability of the active ingredient of garlic and therefore also better effectiveness. Ingestion in the morning on an empty stomach ensures all the effects illustrated.
