Do You Really Need Breakfast? A Fresh Look at the Morning Meal

You’ve heard it a thousand times: “Breakfast is the most important meal of the day.” But that famous phrase? It’s not rooted in science it’s a marketing campaign that began more than a century ago.

While breakfast can absolutely be a healthy and energizing way to start your day, it’s not inherently more essential than lunch or dinner. In fact, its celebrated status owes more to corporate strategy than nutritional necessity.

Here’s a closer look at the history behind breakfast’s reputation, what the research really says, and how to approach your morning meal with intention not pressure.

A Cereal-Fueled Campaign

Before the late 1800s, breakfast wasn’t all that special. People mostly ate leftovers, meats, or hearty dishes in the morning. Enter Dr. John Harvey Kellogg yes, that Kellogg who in the 1890s introduced corn flakes as a bland, easy-to-digest “health food” for ailing stomachs.

It wasn’t long before cereal caught on. By the early 1900s, dozens of cereal factories were operating in Michigan. Kellogg and competitors like C.W. Post began positioning cereal as a digestive solution and health essential.

The real breakthrough came in 1944 with Grape Nuts' "Eat a Good Breakfast – Do a Better Job" campaign. Radio ads boldly declared, “Nutrition experts say breakfast is the most important meal of the day.” It stuck.

The phrase, repeated endlessly in media, education, and advertising, created a cultural norm even though its origins were more corporate than clinical.

Why Breakfast Still Matters (But Isn’t Everything)

Even if it’s not the most important meal, breakfast does serve a purpose especially when it includes nutrient-dense foods.

“Breakfast sets the tone for your day,” says Amy Gorin, RDN, a registered dietitian and owner of Amy Gorin Nutrition. A smart morning meal can help regulate hunger and blood sugar, support brain function, and keep energy levels steady.

According to a 2017 study in Nutrition, people who consumed their largest meal at breakfast tended to have a lower BMI than those who ate more later in the day. Another 2019 study in Nutrients found that men who ate more morning calories had a lower risk of stroke.

Skipping breakfast may even affect your mood. A 2017 study published in Appetite linked breakfast skipping to a higher risk of depression.

Still, it's important to remember that no single meal holds all the power your overall dietary pattern matters more than one plate.

Can You Skip Breakfast?

For some, skipping breakfast may be harmless or even beneficial. Intermittent fasting, for example, often involves delaying the first meal until midday.

Research on time-restricted eating, like the popular 16:8 method, has shown some promise. A 2018 study in the International Journal of Obesity found that alternating between calorie restriction and balance led to greater fat loss. But it’s not for everyone.

“If you're pregnant, breastfeeding, managing diabetes, or have a history of disordered eating, intermittent fasting may not be appropriate,” Gorin says.

More importantly, skipping breakfast can backfire if it leads to intense hunger later in the day. “Some people end up eating 3,000 calories of junk food at night because they skipped meals earlier,” says Dominic Matteo, Master Class Coach with Precision Nutrition.

What to Eat if You Do Choose Breakfast

Whether you're a breakfast devotee or an occasional eater, quality trumps timing. A high-sugar cereal won’t serve you the same way as a balanced plate.

Gorin recommends a mix of:

• Lean protein: Eggs, tofu, Greek yogurt, or protein smoothies

• Healthy fats: Avocado, nuts, seeds, or nut butter

• Whole grains: Oats, whole grain toast, or quinoa

• Fruits or vegetables: Berries, spinach, or bell peppers

This nutrient combo promotes satiety and helps prevent energy crashes.

If you’re looking to level up your morning routine, consider plant-based options with 15+ grams of protein, like tofu scrambles, lentil breakfast bowls, or chia pudding topped with almonds and berries.

The Bottom Line

Breakfast may have been sold as the “most important meal of the day,” but that’s not entirely true or false. It all depends on what works best for your body and lifestyle.

The real takeaway? Eat when you’re hungry, nourish yourself well, and don’t stress over when your fork hits the plate. The most important meal is the one that leaves you feeling good.
