When I first started the One Meal a Day (OMAD) diet, I didn’t expect how much it would challenge not just my body but also my mindset around food. After hearing countless success stories online, I decided to commit for 30 days — one meal per day, no snacks, and lots of discipline. This article shares my honest results, body changes, and what I learned through the process. If you’re curious about how others fare with similar routines, check out this detailed OMAD results case study.

Why I Tried the OMAD Diet
Like many people stuck in a cycle of overeating and sugar cravings, I was looking for a structured way to regain control of my appetite. OMAD seemed simple — one large meal within an hour, followed by 23 hours of fasting. No counting calories, no meal prepping multiple times a day. I was also intrigued by claims that OMAD boosts intermittent fasting benefits such as improved metabolism and fat loss.
To keep myself accountable, I logged my meals and progress daily on MyLeanReset.com, where I track my wellness journey and share practical fasting insights.
The First Week: Adjustment and Cravings
The first few days were brutal. My body constantly reminded me of my old snacking habits. By day four, I felt fatigued and irritable — classic symptoms of sugar withdrawal. However, something shifted by the end of week one: hunger came in predictable waves, and I noticed my energy stabilizing. Drinking black coffee and mineral water during fasting hours became my lifeline.
I learned that hydration was key — not just water, but electrolytes. I added Himalayan salt to my water occasionally to avoid dizziness. This small change made fasting easier and more sustainable.
Body Composition and Weight Changes
By the end of the second week, I had lost almost 6 pounds. My waistline shrunk noticeably, and my face looked leaner. But what surprised me most was not just fat loss — it was the mental clarity. My focus at work improved dramatically, and I wasn’t constantly thinking about food.
Scientific studies support these effects. According to research published on Healthline, OMAD may enhance autophagy — the body’s natural cell-cleaning process that supports longevity and metabolic health.
Energy Levels and Mental Clarity
During week three, my energy felt stable throughout the day. I no longer needed an afternoon coffee crash recovery. My sleep improved, and I woke up feeling lighter and more rested. Mentally, the diet gave me a sense of control I hadn’t felt in years.
Still, I had to be mindful during my one-hour eating window. On days I ate ultra-processed foods, my digestion felt sluggish. When I switched to whole, nutrient-dense meals — high-protein, moderate-fat, and fiber-rich veggies — everything improved.
What I Ate During My OMAD Journey
My meal usually included lean proteins (grilled chicken, salmon, or eggs), healthy fats (avocado, olive oil, nuts), and low-carb vegetables. Occasionally, I added sweet potatoes or quinoa for energy. Hydration was consistent — around 3 liters of water daily.
Unlike traditional calorie counting, OMAD encouraged mindful eating. I paid more attention to hunger cues and portion sizes. Even a small plate of food felt satisfying when eaten after 23 hours of fasting.
The Psychological Shift
OMAD didn’t just change my body — it rewired how I viewed food. I no longer ate because I was bored or emotional. Every bite felt intentional. This minimalist approach to nutrition gave me a new appreciation for simplicity and discipline.
However, OMAD is not a one-size-fits-all plan. Some days, social events or travel made it tricky to stay consistent. I learned to be flexible — occasionally doing a 20:4 fasting schedule when necessary.
Side Effects and Challenges
There were tough days. Headaches, low energy during workouts, and irritability occasionally kicked in. I overcame these by ensuring adequate electrolytes and sleeping 7–8 hours each night. My body needed time to adapt to using fat for fuel instead of carbs.
Interestingly, after about three weeks, my cravings for sugar nearly vanished. My blood sugar levels remained stable, and my skin even looked clearer — possibly from reduced inflammation.
My 30-Day OMAD Results Summary
- Total weight loss: 8.6 pounds (3.9 kg)
- Waist reduction: 2.5 inches
- Body fat: noticeably lower around midsection
- Energy: consistent throughout the day
- Sleep quality: improved
- Mental focus: sharper and calmer
Will I Continue the OMAD Diet?
After 30 days, I decided to continue with OMAD three to four times a week instead of daily. It’s sustainable this way and easier to balance with social life. The key takeaway? OMAD works — but only if approached with mindfulness and adequate nutrition.
If you’re considering trying OMAD, start slow. Transition from 16:8 fasting to OMAD gradually. Track your body’s reactions, and never ignore warning signs like fatigue or dizziness.
Final Thoughts on My OMAD Transformation
The OMAD diet transformed more than just my appearance; it redefined my relationship with food and focus. It’s not a miracle cure — it’s a mental discipline. If practiced responsibly, it can be a powerful tool for fat loss, energy balance, and simplicity in eating habits.
