Medhātithi’s commentary (manubhāṣya):
‘Proper method’—i.e., of worshipping the Gods and so forth; if one does not eat meat, regardless of this manner, but eats it only in the right manner,—‘he b ecomes popular’—loved by the people: he becomes dear to all.

‘He is not afflicted by disease.’—Diseases are produced if a man eats the flesh of lean and enfeebled animals. For this reason also one should eat meat only in the right manner; and by eating it thus, he ‘is not afflicted by disease.’ By eating meat in any other way, he is always afflicted by disease.

‘Like a fiend.’—The term ‘fiend’ stands for a species of lower animals, which eat flesh always in the wrong manner; hence every one who eats it in the wrong manner becomes like a fiend;—this is the sense of the deprecatory simile.—(50).
