Well, firstly, he didn't "devour" them, but rather "absorbed" them. Pigs are the ones who devour. Secondly, haven't you heard about glucose, which is administered to people in comas to sustain their lives? Thirdly, you simply don't believe in the possibilities of modern biochemistry.

The first point is sophistry, and it goes very, very deep because sophistry is practiced elsewhere.
The second point – does religion prevent you from googling what glucose is? It is precisely a carbohydrate. And it is slowly and constantly dripped into the blood through an IV because a LARGE amount of glucose at once can lead to diabetes (one of the tests for diabetes involves giving a suspected diabetic a lot of concentrated glucose and then checking their urine. If they have diabetes, it will be very evident), and if you drip it in small amounts, you can get the same 240 grams over 24 hours.
Regarding biochemistry – I believe in biochemistry, but "tablets instead of food" is the realm of science fiction because the conservation of mass has not been canceled.

They might be able to invent a pill that suppresses the _feeling_ of hunger. But that still won't eliminate the need for food.
