Lips, meet ass.

WASHINGTON (AP) — Surrounded all day and most nights by delicious cakes, cookies, pies and more, Susie Morrison gave in to temptation too often during long hours at work in the White House pastry kitchen.

But no more.

Never a runner, the assistant pastry chef has finished her first 5K run. When the weather cooperates, she pedals her bicycle 26 miles roundtrip to work. She’s eating more vegetables, limiting coffee and drinking up to a gallon of water every day — dietary changes that Morrison says helped her drop 30 pounds from her 5-foot-5 frame in about 18 months.

One person gets most of the credit for Morrison’s lifestyle makeover: Michelle Obama.

While the first lady’s campaign to lower childhood obesity rates will need time to produce results, if ever, the White House is one place where her message about eating balanced meals and getting more exercise is not only resonating, but showing results, too.

“She is a great inspiration for me to focus every day to try harder, and I have,” Morrison said.
