If you start your day with nothing more than a cup of coffee and wait until dinner to eat a substantial meal, it may be time to rethink your routine. Nutrition experts say that breakfast is actually the ideal time to eat your largest meal of the day, a habit that may improve energy levels, increase fullness, and even support a healthier metabolism.
According to registered dietitian Sarah Gold Anzlovar, who spoke with EatingWell, many people skip breakfast or eat only a small meal, either to save calories or because they are short on time.
"A large, balanced breakfast provides sustained energy throughout the morning and may positively affect how you feel for the rest of the day," she explains.
Why a Large Breakfast Benefits Your Body
One of the main reasons is related to insulin sensitivity, the hormone that allows the body's cells to absorb glucose and convert it into energy. Dietitian Talia Pollock explains that the body is more sensitive to insulin in the morning, making it better equipped to process a larger meal efficiently.
The body's internal clock also plays an important role. Studies suggest that the ability to process sugar is greatest during the early hours of the day and gradually declines toward evening. In contrast, eating heavy meals late at night has been linked to disruptions in the body's circadian rhythm and poorer sleep quality, both of which can leave you feeling tired the following day.
After an overnight fast, the body needs readily available energy. While it can function without breakfast, consistently skipping the meal or eating too little may lead to fatigue, reduced concentration, and increased hunger later in the day. The brain, which relies primarily on glucose for fuel, particularly benefits from a breakfast that combines complex carbohydrates with protein. This combination helps support focus, memory, and alertness throughout the morning.
Research has also found that people who eat breakfast regularly tend to be more physically active than those who skip it. Additional studies indicate that the body burns more energy digesting a large meal in the morning than it does digesting the exact same meal in the evening. Researchers believe this is due to more efficient digestive function and improved glucose metabolism during the morning hours.
What Should a Healthy Breakfast Include?
Experts recommend including all three macronutrients in your breakfast:
Complex carbohydrates: whole grain bread, oats, or other whole grains.
Protein: eggs, yogurt, cheese, or legumes.
Healthy fats: avocado, nuts, or tahini.
To maintain steady energy throughout the day, they also recommend eating your first meal within about two hours of waking, having meals every three to five hours, staying well hydrated, and incorporating regular physical activity into your daily routine.
