Less snap, crackle pop, and more soup and salad? More Americans start the day with protein-rich savory meals

A lot of that has to do with people trying to ramp up their protein intake, cut sugar, and that means more Americans are starting their day with protein-rich savory meals rather than traditional cereal or English muffins. In other words, breakfast is starting to look more like dinner.

"It's around eggs or it's actually around a piece of animal protein like a fish or a meat," says Maya Feller, who's a registered dietitian who talked to ABC's Good Morning America. "I'm even seeing people having wilted vegetables or a breakfast salad."

One study finds cereal sales are down 13% over the last five years. Many brands are now manufacturing not just protein-packed cereals, but waffles and pancakes as well.

The grocery aisle is now filled with Kodiak Cakes - protein packed pancakes, protein-filled Eggo waffles, or even traditional breakfast cereals like Cheerios - but now it's Cheerios Protein.

However, the obsession over protein can lead to a lack of other important minerals and nutrients. Your caveman diet needs fruits, vegetables, grains and more. Feller says most importantly, don't skip the fiber.

"Protein is fantastic," says Feller. "However, it does not need to be the center and the end-all be-all of your plate. If you focus on protein and protein alone, your body actually needs the vitamins and minerals from the other food groups, and also your digestive system wants to have fiber."

Nutritionists say options that naturally have protein, such as steak and eggs, are good options, but you should not solely focus on protein.

If you want examples of what that different kind of breakfast looks like, start looking at other cultures. If you've been to Europe, you'll see breakfasts full of whole grain breads, meats, cheeses, veggies and fruit. Asian cultures are more likely to include savory, warm, and whole foods like rice, noodles, or fermented ingredients rather than sweet cereals or pastries.
