Don’t feel like eating all the time, but not ready for OMAD? Let’s talk intermittent fasting… from a different perspective.
Between intermittent fasting enthusiasts who radiate vitality and those who collapse from exhaustion by midday, it’s hard to know where to start. You might be wondering if this famous extended food break is really right for you? And above all, what form should it take?
Because no, intermittent fasting isn’t just about skipping breakfast or doing what your colleague does and only eating at 6 p.m. It’s a bit more nuanced than that (thankfully). And the good news is: there isn’t just one “right” method. There’s the one that fits your life, your body, your energy… and sometimes, it’s more flexible than you might think. Here, there are no rigid rules, no pressure to “stick to it” or “optimize your metabolism.” Together, we’ll explore the different ways to fast, their advantages, limitations, and most importantly, what they can do for you… or not.
Ready to sort through the options: 16:8, 5:2, OMAD, or nothing at all? Let’s take it easy, with a little curiosity and a lot of kindness.
What exactly is intermittent fasting?
Much more than a fad.
In recent years, intermittent fasting has popped up everywhere: wellness blogs, health magazines, YouTube channels, slick Instagram accounts… to the point where you might think it’s just another fad, like green smoothies or paddleboard yoga.
But in reality, this practice has existed for a very long time. Long before science took an interest in it, certain cultures and religious traditions already incorporated periods of fasting of varying lengths. Even in our modern lives, we’ve all experienced those days when we skip a meal without giving it much thought—due to lack of time, hunger, or motivation. But with intermittent fasting, it becomes a conscious choice, whether structured or not.
The basic principle: alternating digestive rest and food intake.
In practical terms, intermittent fasting consists of reducing the eating window during the day, and allowing the body a longer period without food.
This “rest” period allows the digestive system to catch its breath and the body to draw on its reserves.
But be careful, this doesn’t necessarily mean extreme deprivation. There are many different approaches, from the most flexible to the most demanding (we’ll get to that), and the idea isn’t to force yourself, but rather to find a certain balance—or at least to break free from non-stop snacking from morning till night.
In fact, what we call “intermittent fasting” is a kind of broad umbrella encompassing many different approaches. Some are very accessible, others are considerably more challenging. And here’s where it gets interesting: there isn’t one single model to follow… but rather adjustments to make depending on who you are, what you’re going through, and what you’re looking for.
Why is everyone talking about it? (And why isn’t it magic?) If intermittent fasting is generating so much enthusiasm, it’s also because it touches on several key areas: weight loss, gut health, concentration, longevity… There’s even talk of “cellular cleansing” with autophagy (that moment when cells clean themselves up, to put it simply). It’s true that on paper, it sounds appealing.
But beware of oversimplification. Just because some studies show positive effects in very specific contexts doesn’t mean it becomes a miracle cure for everyone, all the time. Every body reacts differently, and above all… the reality of life isn’t the same as that of a laboratory study.
So yes, intermittent fasting can be a good tool. But it deserves to be understood, consciously tested, and above all, adapted—not forced into simply because “it works for others.”
The main intermittent fasting methods
The 16:8: the most popular, but not for everyone
If you’ve heard of intermittent fasting, chances are it’s through this format: the famous 16:8. The idea? Fast for 16 hours and eat within an 8-hour window. Generally, you skip breakfast and have your first meal around noon or 1 p.m., then your last around 8 p.m.
This rhythm is appealing because it’s relatively easy to integrate into daily life. It doesn’t disrupt meals with family or friends too much and can already have a certain effect on blood sugar levels and snacking. But it’s not a miracle cure either. Some people feel great with this format… others not at all. And that’s OK.
The 18:6, 14:10, 20:4… and other flexible variations
In reality, the 16:8 is just a starting point. Some people prefer to fast a little longer, with an 18:6 format (18 hours of fasting, 6 hours of eating), or a little less, with 14:10. It all depends on your comfort level, your energy, and—let’s be honest—your schedule.
There’s even a more challenging version called the “20:4” or “Warrior Diet”: you fast for 20 hours and concentrate your eating into a very small window, often in the evening. This format requires real preparation (and a well-thought-out meal plan), otherwise it can quickly lead to exhaustion.The advantage of these variations is that you can experiment with them. You can easily do 14:10 during the week and 16:8 on the weekend. Nothing is set in stone. The most important thing is to listen to your body.
The 5:2: two light days, five normal days
The 5:2 method is based on a different principle: instead of fasting every day, you choose two non-consecutive days during the week to significantly reduce your calorie intake (around 500-600 kcal), and you eat normally the other five days.
This format appeals to those who don’t like the idea of daily restriction. It can also be a good option for beginners, or for people who need a flexible structure. However, be careful: the “light” days shouldn’t turn into obsessive control. It’s not a punishment, just a voluntary break from eating.

| which we’ve already explored in depth in our dedicated article. It’s undoubtedly the most extreme method of the bunch: 23 hours of fasting, 1 hour to eat. Needless to say, it’s not for everyone. It might suit certain very specific (and motivated) profiles, but it requires real monitoring, an extremely nutrient-dense diet, and a good understanding of oneself. It’s powerful, yes, but not without risks. If you want to delve deeper, I encourage you to read our full article on the subject—we discuss the benefits, but also the possible side effects, without mincing words. | Which method for which profile? | Okay, now that we’ve looked at the main methods, one question often comes up: “But how do I know which one is right for me?” And it’s a very good question. Because we don’t all have the same needs, the same constraints, or the same feelings about hunger. |
| What’s comfortable for one person can be a real source of exhaustion for another. So instead of giving you a “top 3 best fasts,” we preferred to offer you a clear and human-centered overview: depending on your profile, your lifestyle, your relationship with food… which approach might suit you? Profile type | Suitable fasting method | Why it might be a good fit |
| Curious Beginner | 14:10 or 16:8 | Allows you to try it out without drastically changing your daily routine, well-tolerated by most people. |
| Motivated Overweight Person | 16:8 or 18:6 | Helps structure meals, limits snacking, without being too restrictive. |
| Sedentary Adult Male | OMAD (with caution) | May be suitable if your metabolism tolerates it well, with proper monitoring. |

Energy and nutrient needs are higher, it’s best to avoid long fasts.
As you can see, there’s no “perfect” method, only the one that works for you. And above all, nothing is set in stone. You can try a format for a few days, then adjust. Go back to the old one. Adapt your routine to the seasons or your current energy level. Listening to your body isn’t just a slogan—it’s the foundation of any sustainable approach.
How do you know if your method is truly right for you?
Fatigue, food cravings, stress… these are the signs to listen to.
Just because a fasting plan is popular doesn’t mean it will be right for you. And just because you stick to it for a few days “as planned” doesn’t mean everything is going smoothly. The body has its own language. It speaks in its own way—sometimes loudly, sometimes more subtly—and it’s up to us to listen to it, not impose a rhythm that doesn’t suit it.
So if you experience persistent fatigue, uncontrollable cravings as soon as the fasting window ends, unexplained irritability… or even an obsession starting to develop around mealtimes, take a step back. These might be signs that the chosen method isn’t doing you as good as you thought.
And don’t panic: adjusting isn’t cheating. It’s not a “failure.” On the contrary, it’s a sign of maturity and body intelligence. The goal isn’t to “hold on” at all costs. It’s to feel good, stable, and aligned with yourself.
Why you shouldn’t be afraid to adjust or stop
Sometimes there’s that little voice in our head that says, “You started, so now you have to keep going.” It’s often fueled by the desire to do well, or by the pressure we put on ourselves. But in the context of fasting, this logic can be misleading.
You have the right to try things out, then change your mind. You have the right to slow down, or stop if you feel it’s not doing you any good. The body evolves, life changes, and what worked for you yesterday may be unsuitable today. Nothing could be more normal.
What truly matters is your ability to listen to yourself. To recognize when food becomes a source of stress instead of support. Because in the end, it’s not the strictest method that wins… it’s the one that allows you to remain true to yourself, without constant inner struggle.
Fasting, yes… but without rigidity or pressure.
Avoid the pitfalls: competition, perfectionism, guilt.
Intermittent fasting can quickly become a slippery slope. At first, we try it out of curiosity, we observe our bodies… and then sometimes, without realizing it, we start wanting to “do better.” To last longer. To postpone the first meal a little longer. To be stricter, “cleaner.” And that’s when we leave the path of well-being and enter the path of control.
Some fasting methods, especially the most restrictive ones, can be ego-boosting. You feel proud of sticking to it, you like the idea of having “tamed” your appetite. But you have to be realistic: if this practice becomes a source of tension, comparison, or guilt as soon as you “overindulge”… you’re completely straying from the initial goal.
Your body doesn’t need a challenge. It needs a rhythm that suits it, that soothes it, that energizes it. Sometimes, this will mean a well-executed 16:8 fasting plan. Sometimes, regular, well-spaced meals. It’s not a competition. It’s an intimate, evolving adjustment that requires gentleness and patience.
