Martha Stewart says "the loss of freedom and the lack of privacy are extremely difficult," as she nears her first holiday in jail.
But, the convicted executive says she's "safe, fit and healthy." In a posting on her personal Web site, Stewart says she's grateful this Thanksgiving for the support of her fans.
Before entering prison, Stewart said she was "very sad" to miss the holiday season. In the past, she's made TV appearances offering Americans tips for the season's festivities.
A prison spokesman says inmates, including Stewart, will get a Thanksgiving meal Thursday.
She's serving a five-month sentence for lying about a 2001 stock sale and will be released from prison in March.
Stewart has appealed her conviction.
