We compare the two main types of coffee — Arabica and Robusta — in terms of taste, caffeine content, benefits for fasting, growing conditions, shape of berries, country of origin and even price on the Romanian market.
Intermittent fasting is increasingly popular among those who want to lose weight, detoxify their body, or simply have more energy and mental clarity. One of the most discussed drinks that does not spoil fasting (if it is “in its pure form”) is coffee. But not all coffee is the same.
🌿 Origin of Arabica and Robusta coffee
Berries of Arabicacome from a more sensitive shrub that needs more care. Those of Robustaare more hardy and grow in lower areas, being easier to grow on a large scale.
☕️ Differences in taste
- Arabica has a smoother, floral taste with notes of chocolate, hazelnut or fruit.
- Robusta is more bitter, with a stronger taste, sometimes earthy or astringent.
For those who hold intermittent post and consume black coffee (without sugar, milk or other additives), taste becomes essential. Arabica is preferred by those who drink coffee for the pleasure of taste, Robusta — for its powerful effect.
☕️ Caffeine and fasting
One of the most important criteria for those who hold a post is caffeine contentas this can influence energy levels, mood and even appetite.
Robusta is almost double that of Arabica, which makes it ideal for energy boosts during the fasting window.
💲 Price differences
Arabica is more expensive, but it offers a more refined experience. Robusta is preferred in commercial blends or by those who emphasize energy.
📏 Shape, color and structure
- Arabica beans are oval, with a curved central fold.
- Robusta are round with a straight crease.

Arabica has less oil, but more natural sugar — which makes it have a richer flavor.
🚀 What type do you choose during intermittent fasting?
- If you want fine taste and mental clarity: Arabica.
- If you want energy and a tonic effect: Robusta.
- If you hold OMAD or 20/4, Robusta can help in the morning.
- If you are fasting for digestion or anti-aging, Arabica is milder.

📊 Conclusion
Both types of coffee have their place in the routine of an intermittent fasting. The choice depends on:
- Your tolerance to caffeine
- Desired taste
- Your goals: energy, clarity, detox
- Personal budget
The important thing is to choose a coffee that is as natural as possible, without additives, and not to combine it with sugar or milk in the fasting window.
