Is one who is unable to follow the Sunnah of "Sufficient for the son of Adam are a few morsels to keep his back straight" sinful due to the variety of foods and drinks?

The aforementioned Hadith is authentic and warns against excessiveness in eating and drinking, recommending that one-third be for food, one-third for drink, and one-third for the breath. It is the Sunnah for a Muslim to eat and drink without extravagance or stinginess. The ordinary actions of the Prophet, peace be upon him, such as eating and drinking, are not all legislative. The sin of excessiveness relates to what causes definite harm or harm that is highly probable.
