3 Important Reasons to Skip Breakfast

author avatar Dr. Eric Berg 03/27/2024

The effect of skipping breakfast is a very contentious topic in health and wellness circles.

Learn about what happens to your body when you skip breakfast and how you can harness the benefits for your well-being.

The Impact of Breakfast on Metabolism

The widespread notion is that breakfast consumption jump-starts your daily metabolism. Contrary to popular belief, recent evidence suggests that breakfast may not be the sole catalyst for metabolism. Eating breakfast triggers insulin production in our bodies.

Insulin, an essential hormone that regulates blood sugar levels by allowing cells to absorb glucose from the bloodstream, can significantly impact metabolic processes when produced excessively.

Insulin Production and Its Effect on Metabolic Rate

Ingesting food items rich in carbohydrates or sugars - common constituents of many traditional breakfast meals - leads to increased insulin production within our bodies.

As per NCBI study findings, this surge helps manage the immediate rise in blood sugar but also signals your body about abundant energy availability, slowing down fat-burning mechanisms that are no longer needed urgently.

This might seem counterintuitive given how often we hear about 'fueling up' with regular meals, starting with a healthy morning meal like oatmeal or whole grain toast;

However, skipping breakfast could enhance overall diet quality due to reduced caloric intake throughout the day, leading to better weight loss over time, according to research.

Influence Of Elevated Insulin Levels On Weight Gain And Other Health Concerns

A slowed-down metabolism isn't just associated with potential weight gain. However - there are several abnormal metabolic outcomes increased by elevated insulin levels beyond just slower fat burn rates, such as poorer glycemic control, increasing diabetes risk, and even heart disease over time due to chronic inflammation caused by consistently high blood sugar and subsequent insulin responses.

One recent report found that those who ate their largest meal earlier (breakfast) had a significantly lower average glucose level than those who consumed a big dinner later. This indicates the importance of aligning patterns with circadian rhythms to regulate various bodily functions, including digestion rate.

Intermittent fasting concept

Breaking Fast - How Eating Affects Insulin Levels

Breaking your fast, particularly with breakfast consumption, profoundly affects insulin levels. Consuming food increases insulin production as your body prepares to manage incoming nutrients.

This is especially true when consuming carbohydrate-rich or sugary foods, often in traditional breakfast meals. The rise in insulin helps transport glucose from the bloodstream into cells for energy use but can lead to health complications if consistently elevated over time.

Understanding Autophagy

Autophagy, derived from Greek words meaning "self-eating," is a cellular detox process that removes damaged proteins and organelles, promoting cell function maintenance.

This recycling mechanism within our cells frees up resources for new growth and development while eliminating potentially harmful elements.

Fasting periods stimulate autophagy by forcing our bodies to utilize stored fat instead of relying on regular food intake for energy provision.

Skipping breakfast extends this beneficial fasting period, promoting better glycemic control through reduced blood sugar spikes and dips associated with early morning meals, such as increased fasting glucose levels.

Effects Of Elevated Insulin Levels

Elevated insulin levels resulting from frequent meal times or high-carbohydrate diets disrupt both fat-burning and autophagy mechanisms.

Persistently high amounts of circulating insulin shift our bodies towards storage mode, potentially leading to weight gain despite adhering to specific dietary recommendations.

Beyond mere concerns regarding weight management, persistently elevated blood sugar due to poor glycemic control increases risk factors linked to type 2 diabetes, including abnormal metabolic outcomes and increased and poorer overall diet quality.

In addition, the presence of chronic hyperinsulinemia (elevated insulin levels) may play a role in the development of cardiovascular disease by promoting inflammation and restricting blood flow.

Typical Morning Foods and Their Effect on Blood Sugar

The breakfast choices we make can have a profound impact on our blood sugar levels. Specifically, carbohydrate-rich foods cause an immediate surge in glucose, leading to an insulin spike.

Common Carbohydrate-Rich Breakfast Foods

At breakfast, people often eat carbohydrate-rich items such as bread, cereals, pastries, and pancakes that contain high levels of processed sugars. These items are high in processed sugars that swiftly elevate your blood glucose level after consumption.

Beverages like fruit juices also contribute significantly due to their high fructose content.

The Cycle of Hunger Caused by Carbs

Eating carbohydrate-dense meals early in the morning sets off a cycle where sharp rises and falls occur within your body's blood sugar throughout the day.

The initial rise prompts increased insulin production, which triggers hunger pangs as it works towards lowering elevated glucose levels back down again.

This pattern leads you toward eating more often because once those energy stores get depleted - typically around 90 minutes post carb intake - another drop occurs, causing further food cravings before lunchtime arrives.

This disrupts healthy eating patterns and leads to abnormal metabolic outcomes, including weight gain or poorer glycemic control over extended periods if not addressed promptly.

Benefits Of Intermittent Fasting Over Regular Breakfast Consumption

If better metabolism control is what you're aiming for, or perhaps trying out intermittent fasting methods with intentions related primarily to weight loss, skipping breakfast might offer surprising benefits contrary to popular beliefs regarding the concept of 'breakfast being the most important meal.

An extended period without any food intake allows our bodies additional time under lower-insulin conditions, thereby promoting healthier metabolic functions besides reducing risks associated with chronic diseases such as obesity, type-2 diabetes, etc.

Benefits of Intermittent Fasting Over Regular Breakfast Consumption

The debate between breakfast consumption and intermittent fasting continues to rage in health and nutrition. While some believe it's the most important meal of the day, others advocate skipping breakfast as a part of an intermittent fasting routine.

According to recent studies, foregoing your morning meal might provide several health benefits, including promoting autophagy, stimulating new brain cell formation, reducing inflammation, and aiding cellular repair processes.

Promoting Autophagy Through Fasting

Autophagy refers to a biological process where cells recycle their components to maintain optimal function. Research has shown that this self-cleaning mechanism amplifies during periods without food intake.

This enhanced state helps protect against disease and improves metabolic efficiency, which aids weight loss efforts.

When you skip breakfast and tend towards extending overnight fast, you give more time for the body's natural cleanup operation, leading to better overall health.

Brain Health Benefits from Intermittent Fasting

Beyond its impact on physical well-being, intermittent fasting may offer significant mental advantages, too. One such benefit relates to the production of new neurons - something known as neurogenesis.

Studies suggest that this growth is stimulated in specific brain regions responsible for memory and learning functions through prolonged periods without eating.

Regular bouts of fasting have been linked to increased BDNF (brain-derived neurotrophic factor) protein levels, which are crucially involved in cognitive improvement and mood regulation.

Anti-Inflammatory Effects of Skipping Breakfast

Eating triggers insulin release, which over time, can lead to chronic low-level inflammation associated with many common ailments, including heart disease, diabetes, obesity, and even cancers.

A prolonged period of not eating leads to a decrease in inflammatory responses as there are fewer surges in insulin levels throughout the body.


The impact of skipping breakfast is a contentious topic in health and wellness circles. While traditional beliefs suggest that breakfast kick-starts metabolism, recent evidence challenges this notion, highlighting potential benefits associated with extended fasting periods.

Skipping breakfast can lead to lower insulin levels, improved glycemic control, and enhanced autophagy, a cellular detox process.

Intermittent fasting may offer advantages such as promoting neurogenesis, reducing inflammation, and aiding in weight loss efforts.

Understanding the effects of breakfast consumption on metabolism and overall health can help individuals make informed decisions about their dietary habits and fasting practices, ultimately contributing to improved well-being.
