According to lawyers, Lalu can be awarded three to seven years' punishment.
During arguments on the point of sentencing, some citation of SC judgements were also produced where four years' punishment was reduced to one year in a similar corruption related case.
His clarification came after the Special Central Bureau of Investigation (CBI) court on Wednesday found him, RJD chief Lalu Prasad Yadav's son Tejashwi Yadav, and RJD leader Raghuvansh Prasad Singh guilty of contempt of court.
In his application, Lalu Prasad said that the Birsa Munda jail did not have clean drinking water and this may affect his kidneys. The case pertains to fraudulent withdrawal of money from the Deoghar treasury between 1991 and 1994.
Earlier on January 3, the court deferred the matter due to the demise of advocate Vindeshwari Prasad. The sentencing is likely to be pronounced over video conference.

Lalu Prasad Yadav, along with 15 others, was convicted a year ago on December 23 in connection with RC-64/96, pertaining to alleged withdrawal of funds, using fraudulent methods, to the tune of Rs 89 lakhs from Deogarh Treasury between 1990 and 1994 when he was the chief minister of Bihar.
To this, Lalu said he was for personal appearance and assured the court that there would be no slogans raised in the courtroom by his supporters.
Without omitted a punch, CBI Special Court Judge Shiv Pal Singh, who was hearing the case, answered back, "Then, play tabla".
The court had, on Thursday, heard the arguments of the five convicts.
Lalu Yadav told the court in his characteristic style that he too was a trained lawyer, registered to practice in the high court and Supreme Court.
Lalu's lawyer on Friday pleaded for leniency to the former chief minister of Bihar, arguing that the RJD chief was not in good health after his valve replacement at a prominent hospital in Mumbai.
The trial in the case was completed on 13 December in the special CBI court and 10 days later, he was convicted on 23 December.
