She takes the “45-30-25” approach when it comes to her diet.

For many individuals, the ultimate dream is losing weight and feeling their absolute best. Achieving that goal requires hard work, dedication, and consistency to stay on track, but the healthy results make it completely worthwhile.

The singer doesn't deprive herself of some of the foods she loves. In fact, Underwood shared with TODAY.com (via the New York Post) that she swaps in healthier ingredients in certain comfort food dishes.

Take her slow-cooker lasagna recipe, for example. The celeb told TODAY.com, "This is my healthier take on a comforting classic. I call it my 'ugly' lasagna because when you scoop it out of the slow cooker into a bowl, it's not all nicely layered. It's just a big pile of comfort food!"
