Why is there no remnant of his food?
Rashi: He did not leave a remnant to give to Aniyim.
Rashi: citing Sanhedrin 92a: He did not make Chachamim dwell on his table. They are "uva'Seridim Asher Hashem Korei."
Devar Eliyahu: He will not leave an heir [to inherit his authority].
Malbim: Amidst gluttony and stinginess, he eats everything without a remnant.
What is the meaning of "Al Ken Lo Yachil Tuvo"?
Rashi: They will not succeed. This is like "Yachilu Derachav." The verse discusses Anshei Sedom. They were stingy about guests - "Ga'on Siv'as Lechem... v'Yad Oni v'Evyon Lo Hechizikah."
Ibn Ezra: Therefore, he does not hope for his good.
Malbim: Since amidst gluttony, he wants that the food will always remain in his stomach, it does not give to him strength. He is always weak, because "u'Veten Resha'im Techsar" - always.
