AV had zero stomach acid due to a vagotomy-like surgery when he was young, and the only thing he suggested for such a situation was to make sure all food, including meat, was made into paste either by grinding, blending or intense chewing. This makes it easier to digest food. He did not however recommend intense chewing because he thought all the mixing with saliva made some foods digest too fast.
Another thing you could try is marinating foods in lemon juice, which has a similar ph to stomach acid. However, this could over time damage your teeth.
