If you told me years ago that I’d be eating just one meal a day most of the week—and actually loving it—I wouldn’t have believed you.

But here I am, several years into OMAD (One Meal a Day), and it’s been one of the most liberating changes I’ve made to my lifestyle.

That said, I don’t follow it 100% of the time—I do OMAD Monday through Friday and eat more normally on the weekends. This balance keeps me disciplined without feeling restricted, energized without feeling drained, and still allows me to enjoy social meals and treats without guilt.

If you’ve been curious about OMAD, or wondering if you could ever pull it off, let me take you through exactly how I do it, the benefits I’ve experienced, and what I wish I knew before I started.

What is OMAD? (And Why It’s Different from Other Diets)

OMAD is exactly what it sounds like:

You fast for about 23 hours each day.
You eat one large, nutrient-dense meal within a 1-hour window.

Unlike other intermittent fasting methods like 16:8 (where you eat within an 8-hour window) or 5:2 fasting (where you eat normally five days and restrict calories on two days), OMAD is a deep fast—allowing your body to enter a fat-burning, low-insulin state for most of the day.

This is why OMAD is often linked to:

Weight loss and fat burning
Better digestion and gut health
Increased mental clarity and focus
Simplified meal planning
Improved insulin sensitivity

But the biggest benefit for me? Freedom from food obsession.

I no longer have to think about food all day long—no meal prepping, no constant snacking, no worrying about what’s for lunch. It’s just one meal, once a day—and I move on.

OMAD brings a sense of simplicity and mindfulness to eating—which makes it a perfect fit for slow living.

OMAD & Slow Living: Eating with Intention

For me, OMAD isn’t just about fasting. It’s about eating with presence, savoring food, and breaking away from the rush of modern eating habits.

In our fast-paced world, meals are often hurried—eaten while multitasking, scrolling on phones, or consumed mindlessly between meetings. OMAD flips this script.

How OMAD Aligns with Slow Living

Mindful Eating – Since I only eat once a day, I make that meal count. I’m fully present, enjoying each bite instead of rushing through food like a checklist item.
Simplicity & Less Decision Fatigue – No more constant meal planning, grocery runs, or cooking multiple times a day. OMAD simplifies my life, freeing up mental space for creativity, work, and self-care.
Intentional Nourishment – Instead of snacking mindlessly, I focus on one nourishing, beautiful meal—filled with whole, seasonal ingredients that make me feel good.
More Time for Life – Without having to plan three meals a day, I have more time for reading, walking, slow mornings, and creativity—things that bring true fulfillment.
Tuning into Natural Hunger Cues – OMAD has helped me reconnect with real hunger and satiety, rather than eating just because “it’s time.” It has brought me a deeper awareness of my body’s rhythms.

The Science Behind OMAD: Why It Works

OMAD isn’t just about eating less—it’s about harnessing powerful metabolic and cellular processes that optimize your body’s health.

1. Insulin & Fat-Burning

When you eat multiple meals a day, your body constantly produces insulin to help process glucose. Insulin is a storage hormone, and when it’s elevated, your body is in fat-storage mode, not fat-burning mode.

When you fast for extended periods (like with OMAD), insulin levels drop significantly. This forces your body to burn stored fat for energy instead of relying on a constant intake of carbohydrates.

Research from the New England Journal of Medicine shows that prolonged fasting improves insulin sensitivity, lowers blood sugar, and increases fat oxidation—helping with weight loss and metabolic health.

2. Autophagy: The Body’s Cellular Detox Mode

Have you ever heard that fasting can make you “younger” at the cellular level? That’s because of autophagy.

Autophagy is your body’s way of cleaning up damaged cells and regenerating new, healthier ones. Think of it as a cellular spring cleaning—getting rid of old, malfunctioning parts and replacing them with fresh, efficient cells.

OMAD triggers longer fasting windows that activate autophagy, which has been linked to:

Longevity & anti-aging benefits
Reduced inflammation & disease prevention
Lower risk of neurodegenerative diseases like Alzheimer’s

A 2016 study by Yoshinori Ohsumi (who won the Nobel Prize in Medicine for his work on autophagy) found that fasting activates powerful cellular repair mechanisms that may increase lifespan and reduce disease risk.

3. Growth Hormone & Muscle Preservation

One of the biggest concerns people have about OMAD is: Won’t I lose muscle if I’m fasting that long?

Actually, fasting naturally increases human growth hormone (HGH), which helps:

Preserve muscle mass while fasting
Promote fat loss
Support faster muscle recovery

Research in the Journal of Clinical Investigation shows that HGH levels can increase by up to 500% during fasting, which helps protect muscle tissue while the body burns fat for energy.

So as long as you eat enough protein during your meal, you can maintain (or even gain) muscle on OMAD while burning fat.

Common Myths & Misconceptions About OMAD

There’s a lot of misinformation about OMAD, and I’ve heard all the myths. Let’s break them down:

“OMAD slows down metabolism.”

Actually, short-term fasting can boost metabolism by increasing norepinephrine levels and fat oxidation.
Studies show that fasting does not slow metabolism unless calorie intake is drastically restricted over long periods.
Your body becomes more efficient at using stored fat for energy, preventing metabolic slowdown.

“You’ll lose muscle on OMAD.”

Many assume that fasting leads to muscle breakdown, but fasting increases human growth hormone (HGH), which preserves muscle.
As long as you eat enough protein during your meal, your body will maintain and even build muscle.
Strength training while doing OMAD can actually enhance muscle definition since the body burns fat efficiently.

“You’ll be starving all day.”

Hunger comes in waves and fades as your body adapts.
Once you hit fat-adaptation mode, your body burns stored fat for fuel, reducing hunger.
Staying hydrated and including enough fats and protein in your meal keeps you full.

Are You Eating Out of Habit? (I Was!)

Before OMAD, I never really questioned why I was eating. I ate because:

It was “time” to eat (breakfast at 8 AM, lunch at noon, dinner at 6 PM).
I was bored or just needed a “break” from work.
It was a social thing—going out for coffee, meeting friends for lunch.
I craved comfort (hello, stress eating).

But here’s what I discovered after switching to OMAD: I wasn’t actually hungry most of the time—I was just eating out of habit.

Once I pushed past the mental hunger, I realized:

I had way more energy without constant meals.
I didn’t actually “need” breakfast or lunch—I just thought I did.
I felt lighter, sharper, and way less bloated.

If you feel like you’re constantly thinking about food, OMAD might help you break free from that cycle.

How I Make OMAD Work (Without Feeling Deprived)

A lot of people assume OMAD means starving yourself—but it’s the opposite. The key is eating the right foods and the right portions during your one meal.

1. I Don’t Obsess Over Calories (But I Prioritize Nutrients)

Some people make the mistake of eating too little during OMAD. I make sure my meal is big, balanced, and satisfying.

Here’s what my typical OMAD plate looks like:

Healthy Fats – Avocados, nuts, olive oil (they keep me full!)
Lean Protein – Salmon, eggs, chicken, tofu
Complex Carbs – Quinoa, sweet potatoes, whole grains
Fiber-Rich Veggies – Leafy greens, roasted veggies, cruciferous veggies

A meal for me might look like:
Grilled salmon, roasted Brussels sprouts, quinoa, a big side salad with avocado, and a cup of herbal tea or moon milk.

This meal keeps me full for the entire next day—no problem.

2. I Walk to Curb Hunger (Instead of Snacking)

One of the most effective hacks I’ve discovered?

Go for a walk during your lunch hour instead of eating out of habit.

When I first started OMAD, I felt the urge to snack around noon. Instead of giving in, I’d take a 20-minute walk—and 9 times out of 10, the hunger disappeared.

Walking helps:

Distract your mind from food
Boost your mood and energy naturally
Enhance fat-burning by keeping insulin low

It’s one of the easiest ways to support your OMAD lifestyle without intense exercise.

3. I Keep My Weekends Flexible (And Still Get the Benefits of OMAD)

Here’s where I do OMAD differently than some people—I keep my weekends more flexible.

Monday–Friday? I do strict OMAD.
Saturday & Sunday? I eat normally, without a set fasting window.

Why?

I love food. I don’t want to miss out on brunch with friends or cozy weekend dinners.
It keeps me from feeling restricted. I never feel like I’m “on a diet.”
It keeps OMAD sustainable. No burnout, no guilt, just balance.

By keeping it flexible, I get the fat-burning, mental clarity, and simplicity of OMAD during the week, but I also get to enjoy social meals on the weekend.

This has been the perfect balance for me—structured, but not rigid.

Does OMAD Actually Work? (The Honest Truth)

YES—it works, if done correctly.
YES—it simplifies your life, no more meal planning stress.
YES—it burns fat, and keeps you in a low-insulin, fat-burning state most of the day.
YES—it improves mental clarity, because your brain isn’t constantly processing food.

But…

NO—it’s not for everyone. If you have a history of disordered eating, OMAD might feel too restrictive.
NO—it’s not a quick fix. You need to eat nutrient-dense meals to stay energized.
NO—it doesn’t mean you can eat junk. (Trust me, eating a giant meal of fries and pizza won’t make you feel great.)

How to Transition into OMAD (Without Struggling)

If you’re used to eating three meals a day (or snacking frequently), jumping straight into OMAD can feel overwhelming. Here’s how to ease into it:

Step 1: Start with a 16:8 fasting window

Eat in an 8-hour window (e.g., 12 PM – 8 PM) and gradually shorten it.
Your first meal will be at noon, your last at 8 PM.

Step 2: Move to 20:4 fasting

Reduce your eating window to 4 hours (e.g., one big meal and a small snack).
Your meal will be at 4 PM, and then you fast until the next day.

Step 3: Shift to OMAD

Once your body adapts, you naturally eat just one meal a day.
By this stage, hunger is minimal, and you feel more energized.

Pro Tip: Stay hydrated and increase electrolytes (salt, potassium, magnesium) to prevent fatigue and dizziness.

What Happens to Your Body When You Start OMAD?

Week 1: Adapting

Hunger comes in waves, but your body starts learning to burn fat for fuel.
Some people feel tired or moody as they adjust.

Week 2: Fat-Burning Mode

Your body switches from sugar-burning to fat-burning.
Insulin levels drop, and energy levels start stabilizing.

Week 3-4: Metabolic Flexibility

Hunger decreases dramatically.
You feel more alert and focused throughout the day.

Beyond 1 Month: OMAD Feels Natural

Cravings disappear.
Fat loss, mental clarity, and stable energy become the norm.

Different OMAD Meal Approaches

OMAD isn’t one-size-fits-all. Depending on your goals and dietary preferences, you can tailor it to your lifestyle:

Keto OMAD (Low-Carb, High-Fat):

Best for fat-burning and stable energy.
Focuses on healthy fats like avocado, nuts, coconut oil, and fatty fish.
Includes moderate protein and low-carb vegetables.

Plant-Based OMAD:

Emphasizes whole grains, legumes, vegetables, and plant proteins.
Includes nuts, seeds, and avocados for healthy fats.
Works well if combined with high-protein sources like tofu or tempeh.

High-Protein OMAD:

Best for muscle maintenance and athletic performance.
Includes lean meats, eggs, fish, and dairy.
Supports muscle recovery and keeps you full longer.

No matter what, your meal should be balanced, nutrient-dense, and satisfying.

Final Thoughts: Would I Recommend OMAD?

For me, OMAD is more than just a diet—it’s a lifestyle shift toward simplicity, mindfulness, and intentionality.

It removes constant food distractions, freeing up time for what really matters.
It allows me to eat with purpose instead of mindlessly grazing all day.
It helps me feel energized, clear-headed, and in sync with my body.

But at the end of the day, OMAD is just a tool. The goal isn’t to follow rigid rules—it’s to find a way of eating that makes you feel your best while aligning with your values and lifestyle.

FAQs on One Meal a Day Fasting

1. Is OMAD Safe?

Yes, OMAD is generally safe for healthy individuals. However, those with certain medical conditions (diabetes, low blood pressure, eating disorders, pregnancy, or adrenal issues) should consult a doctor before trying it.

For most people, OMAD can be a beneficial lifestyle change when done correctly, ensuring nutrient-dense meals and proper hydration.

2. Won’t OMAD Slow Down My Metabolism?

No! This is a common myth. Studies show that short-term fasting can actually boost metabolism due to increased norepinephrine and growth hormone production.

Your metabolism may only slow if you:

Drastically reduce calories for a prolonged period.
Don’t consume enough protein or essential nutrients.

As long as your one meal is well-balanced and calorically sufficient, your metabolism will remain stable.

3. What Can I Drink During Fasting?

During the fasting period, stick to non-caloric beverages such as:

Water (plain, sparkling, or infused with lemon)
Black coffee (no sugar, cream, or sweeteners)
Herbal or green tea
Electrolyte drinks (without sugar)

Avoid sugary drinks, milk, or anything with calories, as these break the fast.

4. Can I Work Out While Doing OMAD?

Yes! But timing matters:

Strength Training? Do it before your meal to replenish muscles post-workout.
Walking/Yoga? Light exercise is great anytime, even while fasting.
High-Intensity Workouts? Some people thrive on fasted training, while others feel weak. Listen to your body—if needed, eat a small protein-rich snack before exercising.

5. Can I Eat Whatever I Want on OMAD?

Technically, yes. But if you want to feel your best, lose weight, and improve your health, quality matters.

What NOT to do:

Eating ultra-processed junk food, excessive sugar, or refined carbs.
Consuming too little food (leading to nutrient deficiencies).

What to focus on:

Whole, nutrient-dense foods (protein, fiber, healthy fats, and complex carbs).
Balanced meals that leave you satisfied and support long-term health.

6. What Should My One Meal Include?

Your meal should be nutrient-dense and satisfying. A balanced OMAD plate looks like this:

Protein: Chicken, fish, eggs, tofu, tempeh, beans (supports muscle and satiety).
Healthy Fats: Avocados, nuts, seeds, olive oil (keeps you full longer).
Veggies: Leafy greens, cruciferous veggies, roasted root vegetables (for fiber and nutrients).
Complex Carbs (if needed): Quinoa, sweet potatoes, brown rice (provides energy).

7. Will OMAD Make Me Feel Weak or Tired?

Not necessarily. Some fatigue is normal in the first few days as your body adapts, but after that, most people report:

Increased energy
Better mental clarity
Reduced brain fog

If you feel weak long-term, check for:

Not eating enough calories.
Not getting enough electrolytes (sodium, magnesium, potassium).
Not balancing macronutrients properly.

8. How Long Does It Take to Adapt to OMAD?

Most people take 1-3 weeks to adjust.

Week 1: Hunger is challenging, but your body starts adjusting.
Week 2: Appetite stabilizes, and cravings decrease.
Week 3-4: You feel energetic, less hungry, and more focused.

After a month, OMAD often feels completely natural.

9. What If I’m Hungry Before My Meal?

First, assess if it’s real hunger or just a habit.

Hunger Tips:

Drink water, herbal tea, or black coffee (natural appetite suppressants).
Keep busy with work, hobbies, or a light walk.
If hunger is extreme, consider slightly adjusting your fasting window or adding a small snack like bone broth.

Hunger comes in waves—it’s usually temporary and will pass.

10. Can I Do OMAD Every Day?

Yes, but flexibility is key.

Many people do OMAD on weekdays and eat more freely on weekends, which makes it more sustainable long-term.

Others follow a mix of OMAD and 18:6 fasting, depending on their energy levels and lifestyle.

Listen to your body—some days, you may need two meals, and that’s okay!

11. Does OMAD Help With Digestion?

Yes! Fasting gives your digestive system a break, reducing bloating and improving gut health.

Many people report:

Less bloating
More regular bowel movements
Fewer digestive issues like acid reflux

If you experience stomach discomfort, try adjusting your meal composition (e.g., less fiber-heavy foods, fewer raw veggies, or eating more slowly).

12. Can I Do OMAD If I’m a Woman?

Yes, but women should be more mindful of their hormones.

Some women thrive on OMAD, while others find it too restrictive.
Adjust your fasting based on your menstrual cycle—some do better with a shorter fasting window before their period.
If you experience fatigue, mood swings, or irregular periods, try a more flexible fasting schedule like 18:6 or 20:4.

13. Will OMAD Help With Weight Loss?

Yes! OMAD naturally creates a caloric deficit and optimizes fat-burning.

How it helps:

Reduces insulin levels, shifting the body into fat-burning mode.
Prevents snacking and mindless eating.
Encourages metabolic flexibility, meaning your body efficiently burns fat for fuel.

Weight loss tip: If weight loss stalls, check portion sizes—some people unknowingly eat more than they need in one meal.

14. Can OMAD Improve Mental Clarity?

Absolutely! Many people experience better focus and reduced brain fog because:

Insulin levels remain stable (no sugar crashes).
The brain thrives on ketones (fat-derived fuel) from fasting.
Digestion isn’t constantly draining energy.

This is why many high performers, entrepreneurs, and creatives use fasting to enhance productivity.

15. What If OMAD Doesn’t Work for Me?

Not everyone thrives on OMAD, and that’s okay! Consider adjusting:

Try a 20:4 or 18:6 fasting schedule instead.
Ensure you’re eating enough calories and nutrients.
Focus on stress management, as stress can affect fasting tolerance.

Fasting is a tool, not a rule—use it in a way that supports your well-being.
