HIGHLANDS RANCH, Colo. -- Can you manage your weight with milk?

A Highlands Ranch mom whom 7NEWS featured last year was chosen to take part in the Got Milk? Great American Weight Loss Challenge. And because of all the weight she lost, you will now be seeing more of her in your local grocery store.

Robin Seaber said she was always on the go, juggling duties as a mom and wife but she rarely left time for herself. She was happy but not as healthy as she would have liked.

"I truly feel like my life has changed," Seaber said. "I'm a small boned person so really this is the size body I should have -- I was just hiding it all those years."

But now that she lost 46 pounds, Seaber's featured in a full-page ad and looks so good that a PR firm will put life-sized photos of her in grocery stores.

"The girls think it's a little strange but they like it. My family is very proud of me," said Seaber.

Seaber did it by reducing her calories and exercising regularly.

"All my portions are smaller but I also eat five times a day," she said. "And I exercise faithfully three days a week."

And she drinks milk.

"I have a glass of milk in the morning when I first get up before I take the kids to school and another glass at night before I go to bed."

This 45-year-old mom's success means her milk-mustached smile and lean figure will be staring back at everyone in grocery stores and magazines nationwide.

"My kids are thrilled because mom looks good in a pair of jeans. That's always great when you're a teenaged girl. My husband is thrilled for the same reason and because they love me and they wanted me to be healthy," she said.

Seaber views all of it not as a diet but as a lifestyle change. Seaber said there will be no more yo-yo diets for her and she said if she can do it, so can you.
