For athletes and fitness enthusiasts alike, the debate surrounding the necessity of breakfast—specifically high-protein breakfasts—continues to be a hot topic. Whether to start the day with a hearty meal full of protein or to train fasted has spurred much conversation among trainers, nutritionists, and athletes. Some swear by their high-protein morning ritual, while others find success in skipping breakfast to train in a fasted state.
In this article, we will explore the benefits and drawbacks of consuming a high-protein breakfast versus skipping breakfast entirely before training. By examining research, professional opinions, and real-life experiences from athletes, we aim to provide clarity on whether a high-protein breakfast truly holds the key to sporting greatness or if it’s an overhyped concept.

Breakfast: The Most Important Meal of the Day?
The phrase “breakfast is the most important meal of the day” has been echoed in the nutrition world for decades. But does this hold true for athletes? Let’s begin by referring to a well-regarded study published in the paper “Breakfast in Human Nutrition: The International Breakfast Research Initiative.” This extensive research effort looked at breakfast habits in countries including Canada, Denmark, France, Spain, the UK, and the USA. The findings revealed that individuals who consume breakfast regularly tend to have a lower risk of obesity and are less likely to experience weight gain. By filling up early in the day, people are less likely to overeat later, contributing to better overall health outcomes.
Another study, titled “Eat or Skip Breakfast?” specifically explored the effects of breakfast on stress and mental health, particularly in adolescents. The research found that eating breakfast, especially carbohydrate-rich cereals, contributed to better physical and mental well-being. The study authors suggested that carbohydrates help lower cortisol levels, which reduces the body’s stress signals. For athletes, this means that a carbohydrate-heavy breakfast may aid in reducing pre-exercise anxiety and improving focus.
From an energy standpoint, yet another study found that a substantial breakfast correlates with higher alertness, reduced fatigue, and an improved mood post-exercise. The conclusion? A well-balanced breakfast can lead to better performance and mental sharpness after a workout.
Athletes and the High-Protein Breakfast Routine
When it comes to professional athletes, many swear by the effectiveness of a protein-packed breakfast before training or competition. Protein is known for its role in muscle repair and recovery, but it also helps keep athletes feeling full and energized for longer periods.
Louis Parkison, a renowned climbing coach and former Great Britain climber, is one such proponent of a high-protein breakfast. His pre-training meal of choice consists of rice, scrambled eggs, and black coffee. With this combination, Parkison fuels his body with both quick-release carbohydrates from the rice and long-lasting protein from the eggs. The added caffeine gives him a mental boost to power through his training sessions.
Former US Olympian Samantha Peszek also emphasizes the importance of breakfast for athletes. She recalls being required to eat breakfast before her morning practices, noting that without proper fuel, she couldn’t perform at her best. Her go-to breakfast? Two eggs, half an English muffin with peanut butter, or plain oatmeal, depending on the weather. Protein in the eggs and peanut butter combined with slow-release carbs from the oatmeal ensured Peszek had enough energy to sustain her through intense training sessions.
The pattern is clear: athletes who consume high-protein breakfasts typically report higher levels of energy and improved performance during their workouts. But it’s not just protein that makes these meals successful—carbohydrates and healthy fats, such as those found in whole grains and peanut butter, also play essential roles.
The Importance of Routine
Brian Johns, a Canadian swimmer who competed in the 2008 Summer Olympics, reinforces the importance of a pre-race breakfast routine. While Johns recognized that breakfast played a vital role in his performance, he also noted that maintaining a consistent routine was equally crucial. Being at the mercy of whatever food was available in the Olympic village cafeteria, he had to stick to foods that were familiar and easy on the stomach.
For Johns, scrambled eggs on toast with peanut butter was his go-to breakfast, a meal that provided a good balance of protein, fats, and carbohydrates. His experience highlights a valuable lesson for athletes: while breakfast is important, the key is consistency. Eating foods that are familiar and easy to digest can help athletes avoid digestive issues that may impair performance.
Fasted Training: Is It a Hack for Fat Loss?
While many athletes favor a protein-heavy breakfast, some take a different approach by training in a fasted state. Fasted training, particularly aerobic exercise, has gained traction among those looking to burn fat efficiently. When you exercise without eating first, your body is forced to tap into fat stores for energy due to the depletion of glycogen stores. This process is known as lipolysis, and for some athletes, it is a game-changer in terms of fat loss.
A 2023 study found that six weeks of fasted aerobic exercise resulted in higher fat oxidation rates, meaning that participants burned more fat during their workouts than those who trained after eating. This finding is particularly relevant for athletes aiming to reduce body fat while maintaining lean muscle mass.
Farren Morgan, founder of Tactical Athlete Training & Supplements and a former soldier, is a strong advocate for fasted workouts. Morgan believes that exercising on an empty stomach helps the body become more efficient at utilizing fat as an energy source. He also points out the mental toughness required to push through an intense workout without food, a skill that can translate into greater resilience in everyday life. Additionally, Morgan highlights how fasted workouts can improve insulin sensitivity, which helps regulate blood sugar levels and reduce the risk of metabolic diseases.
Fasted Training Isn’t for Everyone
While fasted training may work well for some, it doesn’t suit every athlete. John Dewey, director of Epic Road Rides, has experimented with fasted bike rides over the years but ultimately found that they didn’t work for him. Dewey’s training for hilly cycling events required a higher energy output, and he found that skipping breakfast led to subpar performance and poor recovery. After decades of trial and error, he concluded that fasted training was counterproductive to his goals, as hunger often caused him to make poor food choices later in the day.
Similarly, athletes like Jack Binstead, founder of England’s Adaptive Padel team, have evolved in their approach to breakfast over time. Binstead, who competes on the international adaptive circuit, realized that his wheelchair training impacted his digestive system differently. As a result, he opted for smaller, lighter breakfasts before training to avoid feeling too full or sluggish. His ideal pre-competition meal? Eggs on toast with coffee—simple, easy to digest, and energizing.
The Verdict: Should You Eat a High-Protein Breakfast or Train Fasted?
Ultimately, whether or not to eat a high-protein breakfast comes down to personal goals, preferences, and how your body responds to food. If you are an athlete looking to perform at the highest levels, a high-protein breakfast with a balance of carbohydrates and healthy fats is likely the best choice to ensure sustained energy throughout your workout. The benefits of breakfast—improved mood, reduced fatigue, and enhanced focus—are well-supported by scientific research.
On the other hand, if fat loss is your primary goal and you’re training in a less competitive environment, fasted workouts may offer some advantages. The process of lipolysis helps your body burn fat more efficiently, and the mental challenge of training without food can help build discipline and focus. However, it’s important to approach fasted training carefully, as it may not be suitable for everyone, especially those who require higher energy output.
