White House executive pastry chef Bill Yosses is resigning after First Lady Michelle Obama fundamentally changed his job duties to focus on healthier food.

Yosses is leaving the White House in June to work on a new project focusing on “food literacy” and The New York Times says Michelle is “partly to blame.” The openly gay chef was hired by Laura Bush in 2007 to make his trademark cookie plates and sugar sculptures. Mrs. Obama took over in 2009 and ordered Yosses to make healthier plates in smaller portions.

Yosses began replacing butter with fruit puree and sugar with honey and agave. But Yosses was never fully committed to the new policy.

“I don’t want to demonize cream, butter, sugar and eggs,” Yosses said, noting that his departure from the White House is a “bittersweet decision.”

Michelle Obama said in a statement that she is “incredibly sad to see Bill Yosses go.”

“I am also so grateful to him for his outstanding work, not just as the White House pastry chef, producing the most delectable creations for everything from birthday celebrations to state visits, but also as a key partner helping us get the White House kitchen garden off the ground and building a healthier future for our next generation. I wish Bill and his husband, Charlie, all the best in their future endeavors,” Michelle Obama said.
