Breakfast questioned: You can live without it

Breakfast: The meal that was never essential

You can live perfectly well without eating breakfast. This claim, made by a forum user, has peine a seemingly settled war: is breakfast the most important meal of the day or an overrated habit? For decades, we heard the mantra to eat like a king at breakfast, a knight at lunch, and a beggar at dinner. Today, that narrative is shaky, not because of new studies, but because more people realize they can last until noon with just coffee. Far from being resolved, the discussion has become a clash between dietary tradition and the anecdotal evidence of those who skip the first meal.

What experts say and why it’s disputed

The starting point is simple: humans can live without breakfast. Defenders argue our bodies are designed to withstand periods without food and that breakfast is merely a social convention. The classic counterargument appeals to energy: no breakfast means no strength for the morning. But this meets a wall of contradicting testimonials. Some train fasted for a decade, claiming doubled strength and energy. Others never eat breakfast and remain healthy. The debate isn't new, but now it's fought openly.

The biological argument: proteins, cortisol, and absorption

Things get complicated in physiology. One school says proteins absorb better in the morning when cortisol converts food into energy and regenerates muscle mass. Another argues the opposite: evening is optimal for protein because the body grows during sleep. A third adds an uncomfortable nuance: nighttime protein intake activates the nervous system, while sugars sedate it. Essentially, we are wired differently than popular wisdom suggests. If there is a conclusion, it's that chronobiology of eating remains a contested field.

Intermittent fasting: From trend to routine

Intermittent fasting has flipped the script. No longer a guru eccentricity, many practice it as a routine. The most cited formula is 16 hours of fasting and an 8-hour eating window. Supporters say it works, slims the silhouette, and requires little effort. Skeptics respond it's nothing new: everyone fasts while sleeping. The difference is breaking the fast upon waking versus delaying it until noon. Ultimately, the debate is whether this is an improvement or just a fancy-named trend.

The Spanish context: Late dinners and schedules

A often ignored factor is timing. In Spain, dinner is later than in the rest of Europe, so fewer hours pass since the last meal before waking. This explains why many lack appetite in the morning, preferring a mid-morning snack. Adapting to global schedules would require changing solar time, work, and commercial hours. Since that won't happen, meals stay put. Consequently, the Spanish breakfast, if eaten, is usually light: coffee, cookies, juice. Little to defend, little to attack.

Breakfast as an economic thermometer

Unexpectedly, the debate shifted to finances. Some argue the real problem isn't nutritional but economic: with inflation and current prices, more people eat only one meal a day. In this framework, breakfast stops being a health choice and becomes a dispensable luxury. The irony is that skipping breakfast advice can be read as dietary guidance or resignation regarding grocery costs. It depends on who gives the advice and why.

What evidence doesn't settle

The core issue is the lack of definitive studies. We need long-term trinc-ups, group comparisons, and more than opinions. Meanwhile, sensible advice, repeated even by fasting advocates, is that each person is unique; what works for one may not for another. Listening to your body, they say, is better than listening to any expert. Curiously, both sides agree here. Given these credentials, breakfast will likely remain disputed for years. Not because it matters much, but because arguing about it is free.
