A Trainer Explains the Diet Plan That Helped Her Lose 50 Pounds (Oreos Are Involved)

Last month we introduced you to a woman named Brittany who was her own success story; she lost 50 pounds, built muscle, got healthy, and eventually became a trainer. And she's still totally obsessed with Oreos. And cereal. And ice cream.

So how does she eat like that and still stay so incredibly lean and muscular? Flexible dieting. It's a concept that has been central to Brittany's success and sustained weight management — and her happiness!

The concept of flexible dieting is a method of counting macros. You set up your macronutrient proportions, and as long as the foods for your day fit into those proportions ("if it fits your macros"), you're good to go.

Another one of her secrets is that she doesn't just have three meals a day — she has three meals, two snacks, and dessert. Because Oreos. She focuses on lean proteins, healthy grains, and lots of veggies while still eating her favorite foods.

"Flexible dieting is an approach that allows you to find a balance between healthy and fun foods, all while still allowing you to reach your fitness goals," Brittany told POPSUGAR. "I eat different foods every day! But here is a rough idea of the foods that I consume daily."
