Key Takeaways
  • If you can skip breakfast, "Bulletproof Coffee (grass-fed butter/ghee + MCT)" can help maintain energy levels throughout the morning.
  • Carbohydrates (white rice, bread, cereal) in the morning can easily cause blood sugar fluctuations, so it's safer to limit them if possible (e.g., Chang et al., 2019).
  • Fruit juices and fructose may lead to liver burden and a lack of satiety, so consider reviewing their intake first thing in the morning.
  • As an alternative, a low-carb, high-quality protein and fat-centric breakfast (eggs, fish, soy products, nuts, avocado, etc.) is effective.

What Should You Eat for Breakfast? A Gentle Breakfast Guide for Those Not Doing Intermittent Fasting

Breakfast is an important habit that sets the tone for your day. Our geefee team also experiments regularly, and honestly, we feel that "breakfast is different for everyone." However, a scientific trend we want to emphasize is that "limiting morning carbohydrates can lead to more stable blood sugar fluctuations." Here, we will share practical breakfast choices you can start today, especially for those who are not doing intermittent fasting.

Our Recommendation: Skipping Breakfast + Bulletproof Coffee (Our Experience)

From our own experience, practicing a 16-hour intermittent fast (including sleep) and having only Bulletproof Coffee in the morning was most effective for maintaining focus and controlling hunger during the morning hours. Coffee with grass-fed butter, ghee, and MCT oil contains zero carbohydrates, and the high-quality fats provide a sustained energy source. Of course, it is high in calories, so if you have concerns about weight management or lipid metabolism, please consult a doctor.

Why You Should Avoid Morning Carbohydrates (From a Blood Sugar Fluctuation Perspective)

Consuming carbohydrates like white rice, bread, or cereal in the morning can cause a rapid spike in blood sugar after meals, followed by a sharp drop that can lead to hunger and sluggishness in the morning. A 2019 study by Chang et al. reported that a diet restricting morning carbohydrates (low-carb, high-fat) improved post-breakfast blood sugar spikes and 24-hour blood sugar fluctuations. Considering the risk of diabetes and stable daytime performance, choosing a breakfast focused on protein and fat while limiting carbohydrates in the morning is an effective option.

Fruits and Fruit Juices to Avoid in the Morning, and Why

Fruits and fruit juices in the morning may seem healthy at first glance, but fructose is easily metabolized by the liver, and consuming a large amount of fructose on an empty stomach can burden the liver. Past reports and studies have pointed out that fructose can impair leptin sensitivity, making it difficult to feel full and increasing the risk of overeating (reports from ScienceDaily, etc.). Eating a small amount of whole fruit might lead to a gentler rise in blood sugar due to fiber, but it's best to avoid juices or large quantities first thing in the morning.

Specific Breakfast Menu Examples (Low-Carb, High-Protein/High-Fat)

Menus You Can Implement Immediately

  • Bulletproof Coffee (grass-fed butter/ghee + MCT) — Easy to drink and try.
  • Egg dishes (boiled eggs, omelets, scrambled eggs) + leafy green salad — Protein keeps you feeling full.
  • Smoked salmon or canned tuna + avocado — A combination of good fats and protein.
  • Tofu or natto + a small amount of seaweed and vegetables — A low-carb choice that Japanese food lovers will appreciate.

Notes and Variations

If you're concerned about hunger between meals, a handful of nuts or unsweetened yogurt (Greek yogurt) with chia seeds can increase satiety. However, be mindful of the quantity, as nuts and full-fat dairy products are high in calories. Even if you switch to a low-carb breakfast, the key is to consume enough satisfying protein to avoid overeating at lunch. There are also studies (Blom et al., 2006) showing that high-protein breakfasts suppress ghrelin (the hunger hormone), so the benefits of including protein in the morning are significant.

Common Concern: Will I Overeat at Lunch if I Skip Carbohydrates?

This is a valid concern, but an older study (Stubbs et al., 1996) reported that even in groups that skipped carbohydrates in the morning, the total intake at lunch did not necessarily increase. While there are individual differences, a satisfying high-protein/high-fat breakfast often contributes to overall appetite control throughout the day. In our experience, choosing a breakfast that settles your stomach in the morning made it easier to maintain focus in the afternoon.

Summary

What you eat for breakfast makes a difference in your daily blood sugar stability and concentration. If intermittent fasting is difficult for you, we recommend switching to Bulletproof Coffee or a breakfast centered on low-carb, protein, and good fats. Limit refined carbohydrates like fruit juices, white rice, and bread in the morning, and combine eggs, fish, legumes, nuts, and avocado to maintain satiety. Try changing one meal in the morning for a week, and you're sure to find what works for you. We've introduced some methods that we've tried and found effective, so please give them a try within a comfortable range.
