White House chef Sam Kass will stop cooking for the Obamas at the end of the year, Eater DC reported.

Kass led the executive mansion's kitchen for six years and is poised to move to New York to live with his wife, MSNBC host Alex Wagner, according to Politico.

The Washington magazine dubbed Kass the nation's "de facto food policy czar" because in addition to his assignment as chef to the First Family, he served as executive director of first lady Michelle Obama's "Let's Move!" initiative.

"From constructing our 'Kitchen Garden' to brewing our own 'Honey Brown Ale,' Sam has left an indelible mark on the White House," President Obama told the publication. "And with the work he has done to inspire families and children across this country to lead healthier lives, Sam has made a real difference for our next generation."

Obama had made Kass a senior policy adviser, and the chef played "an integral role coordinating major food and agriculture policies throughout the administration," Politico observed.

"Sam has made a real difference for our next generation," the president added. "Over the years, Sam has grown from a close friend to a critical member of my team, and I am grateful for his outstanding work and look forward to seeing all that he will continue to achieve in the years ahead."

Kass will "remain engaged" with the "Let's Move!" initiative and keep working on school nutrition, the White House noted.

"Sam leaves an extraordinary legacy of progress, including healthier food options in grocery store aisles, more nutritious school lunches, and new efforts that have improved how healthy food is marketed to our kids," said first lady Michelle Obama, according to USA Today.

The Obamas have a close relationship with the chef and attended his wedding, the newspaper detailed.

The food industry and health advocates, meanwhile, are waiting to find out who will replace Kass as White House chef, Politico said. His successor will be instrumental in implementing many of Obama's food and agriculture policies. Major changes, however, are not expected, according to Beth Johnson, who heads the industry consulting firm Food Directions.

"Sam has been instrumental in driving the administration's food policy initiatives," she said. "Though this leaves the question of what happens on these issues from here, he is leaving at a time where much is already in motion."
