Arias/AP; O'Boyle/AP Sarah Palin has repeatedly taken aim at Michelle Obama's efforts to fight childhood obesity.

She's all for cutting flabby government, but Sarah Palin wants Michelle Obama to butt out of keeping kids from getting fat.

The moose-munching Tea Party darling is picking a fight with the First Lady - over dessert.

"Where are the s'mores ingredients?" the sharp-elbowed hockey mom growled in Sunday's episode of her outdoorsy TLC show "Sarah Palin's Alaska."

"This is in honor of Michelle Obama, who said the other day we should not have dessert," Palin said mockingly as she rummaged through her kitchen cupboards for graham crackers, marshmallows and chocolate.

The former vice presidential candidate was apparently referring to a speech in which Michelle Obama did not quite put a ban on sweet treats.

"As I tell my kids, dessert is not a right," Obama told the NAACP in July, touting her "Let's Move" campaign to combat childhood obesity.

While Obama's program does not explicitly tell parents to avoid dessert, it suggests cutting back on sugar.

It was the second time in a month Palin has bashed the First Lady's calorie-curbing movement.

"What she is telling us is she cannot trust parents to make decisions for their own children, for their own families in what we should eat," the ex-Alaska governor told radio host Laura Ingraham last month.

"Instead of a government thinking that they need to take over and make decisions for us according to some politician's or politician's wife's priorities, just leave us alone . . . "

The White House declined to comment on Palin's barbs, or her appetite for s'mores.

Studies show that one in three American children is overweight or obese, increasing their risk of developing life-altering illnesses like diabetes.

The First Lady's "Let's Move" program encourages families and schools to adopt a healthy approach to activity and nutrition.

Obama has led by example. She has planted a vegetable garden at the White House, and last month she led kids in an exercise class at a Police Athletic League center in Harlem.

In her efforts, Obama has not been holier than thou, admitting to having a soft spot for at least one dessert.

"One of the reasons I talk about pie and burgers is because if you tell people they can never have the stuff they love, they'll shut down," she told Ladies' Home Journal in August. "What is life without the things you love to eat? For me it's pie."
