Intermittent fasting has been a hot topic for years, but among its variations, the One Meal a Day (OMAD) approach stands out as both extreme and intriguing. Over the past 30 days, I committed myself to OMAD, not only to challenge my discipline but also to understand the true effects it can have on the body, mind, and lifestyle. This is my full account of the results, benefits, struggles, and lessons learned during this experiment.

Why I Decided to Try OMAD
My motivation stemmed from curiosity and a desire to simplify my eating routine. With busy schedules, meal prepping three times a day often felt overwhelming. OMAD offered a way to cut down decision fatigue while exploring the potential health benefits many claim, including improved metabolism, fat loss, and mental clarity. Research has shown intermittent fasting can positively impact overall health and longevity, which further encouraged me to test this method for myself.
Setting the Rules for the 30 Days
I committed to eating only once every 24 hours, usually in the evening, to make social interactions easier. I allowed myself water, black coffee, and green tea during fasting hours. For meals, I focused on nutrient-dense foods, incorporating proteins, healthy fats, vegetables, and some complex carbs. To maintain structure, I logged everything to ensure I was not undernourished.
Week One: Initial Struggles
The first few days were the hardest. Hunger hit strong around lunchtime, and energy dips were noticeable. However, hydration helped curb cravings. I also noticed how much mindless snacking had been a habit before this challenge. By the end of week one, my body began adapting, and the cravings were less severe.
Week Two: Energy Stabilization
By the second week, I experienced greater mental clarity and stable energy levels. My focus during work hours improved, and I felt less sluggish after meals. Interestingly, I began enjoying the freedom of not worrying about multiple meals daily. Studies from Harvard Health suggest fasting may improve insulin sensitivity, and I started noticing fewer sugar crashes throughout the day.
Week Three: Visible Results
By week three, physical changes became noticeable. My waistline slimmed down, and I lost around 6 pounds. My digestion improved significantly, and I felt lighter overall. The simplicity of OMAD also freed up time for hobbies and reduced grocery costs. I wrote about similar progress tracking tips in this guide: How to Track Your Progress with Intermittent Fasting.
Week Four: Adaptation and Balance
By the final week, OMAD felt natural. Hunger signals became predictable, and my body adjusted to consuming one large, balanced meal. Sleep quality improved, possibly because digestion wasn’t interfering during the night. I also noticed my skin looked clearer and energy levels remained consistent.
Challenges Faced During OMAD
Despite positive outcomes, OMAD was not without challenges. Social gatherings often revolved around meals at different times, making it awkward to stick with my plan. There were also days when I underestimated calorie needs, leaving me slightly undernourished. As explained in my post on how to sleep better while fasting, ensuring balance and proper nutrition is key for sustainability.
Benefits I Experienced
- Weight management: Natural calorie reduction led to steady fat loss.
- Better focus: Clearer thinking during long fasting windows.
- Improved digestion: Fewer bloating episodes.
- Time efficiency: Less meal prep and grocery shopping.
Drawbacks to Consider
- May not be suitable for athletes or people with high energy demands.
- Can cause nutrient deficiencies if meals are not well-planned.
- Social limitations due to strict eating windows.
Final Results After 30 Days
At the end of 30 days, I had lost nearly 10 pounds, improved my relationship with food, and gained new perspective on discipline. OMAD helped me realize the power of mindful eating and self-control. While I don’t plan to follow OMAD permanently, I’ll likely use it occasionally as a reset or for busy days.
Is OMAD Right for Everyone?
Not necessarily. People with medical conditions, pregnant women, or those with disordered eating history should avoid OMAD. For others, especially those curious about minimalism and metabolic health, trying OMAD under proper guidance may be worthwhile. Always consult a healthcare provider before starting.
FAQ About My OMAD 30-Day Journey
Did you experience side effects while doing OMAD?
Yes, mostly in the first week, such as hunger and fatigue. These symptoms faded as my body adapted.
How many calories did you eat in one meal?
I averaged around 1,800 to 2,200 calories per meal, focusing on nutrient density.
Would you recommend OMAD to beginners in fasting?
Not directly. Starting with 16/8 or 18/6 intermittent fasting may be easier before attempting OMAD.
