FAQs

Your OMAD meal is too large or calorie-dense

One of the most common reasons why OMADers don’t lose weight is that they consume too many calories in their one meal. Even if you’re eating healthy, nutrient-dense foods, if you’re exceeding your daily calorie needs, you’ll still gain or maintain weight. To avoid this mistake, you should:

Calculate your daily calorie needs based on your age, gender, height, weight, and activity level.
Determine your target daily calorie deficit (e.g., 500-1000 calories/day) to lose 1-2 pounds per week.
Use a food scale and/or tracking app to measure and log your OMAD meal’s ingredients and portions accurately.

Gradually reduce the size or calorie density of your OMAD meal until you’re in a calorie deficit.

You’re eating the wrong types of food for your OMAD meal

Another factor that can sabotage your OMAD weight loss goals is choosing the wrong types of food for your one meal. Some foods, such as processed or refined carbohydrates, sugary drinks, and high-fat or high-sodium meals, can make you feel bloated, lethargic, or hungry again shortly after eating. To optimize your OMAD meal composition, you should:

Prioritize whole, unprocessed, and fiber-rich foods, such as fruits, vegetables, whole grains, and lean proteins.
Avoid or minimize highly processed, sugary, and fried foods that provide little satiety or nutrition.

Experiment with different meal combinations and seasonings to keep your OMAD meal varied and satisfying.
Consider consulting a registered dietitian or nutritionist for personalized OMAD meal planning advice.

You’re not eating enough protein or fiber in your OMAD meal

Protein and fiber are two critical nutrients that can help you feel full, build and maintain muscle mass, and regulate your blood sugar levels. If you’re not getting enough of these nutrients in your OMAD meal, you may experience hunger pangs, cravings, and energy crashes, which can hinder your weight loss progress. To ensure that you’re getting enough protein and fiber in your OMAD meal, you should:

Aim for a protein intake of at least 0.8 grams per kilogram of body weight per day.

Include protein-rich foods such as chicken, fish, tofu, eggs, or legumes in your OMAD meal.
Add fiber-rich foods such as vegetables, fruits, nuts, and seeds to your OMAD meal to increase satiety and support digestive health.
Consider taking supplements such as whey protein, collagen, or psyllium husk if you struggle to meet your protein or fiber needs through food alone.

You’re drinking calorie-containing beverages outside your OMAD meal

Although OMAD allows you to consume any non-caloric beverages during your fasting window, drinking calorie-containing beverages such as soda, juice, milk, or alcohol can sabotage your weight loss goals. These drinks are often high in sugar, artificial flavors, or additives that can spike your blood sugar levels, increase your appetite, or disrupt your sleep. To avoid this issue, you should:

Stick to non-caloric beverages such as water, unsweetened tea or coffee, herbal tea, or sparkling water during your fasting window.

Avoid drinking calorie-containing beverages before or after your OMAD meal, as they can add unnecessary calories and blunt your hunger and satiety signals.
If you must drink calorie-containing beverages, choose lower calorie options such as light beer, wine, or spirits, and limit your intake to one or two servings per week.

You’re snacking or grazing during your fasting period

Another pitfall of OMAD is snacking or grazing during your fasting period, which can break your fast, spike your insulin levels, and disrupt your metabolic benefits. Some OMADers might succumb to temptation by nibbling on small snacks or sipping calorie-containing drinks, while others might unintentionally eat more significant meals than planned due to hunger or boredom. To avoid this mistake, you should:

Set clear boundaries for your fasting and eating windows and stick to them consistently.
Plan your OMAD meal ahead of time and avoid keeping tempting snacks or drinks around.

Stay busy or distracted during your fasting window with activities such as exercise, work, hobbies, or socializing.
If you feel too hungry or thirsty during your fasting window, drink water or non-caloric beverages and remind yourself of your weight loss goals and progress.

You’re not giving yourself enough time to adjust to OMAD

If you’re new to OMAD or have recently switched from a different IF protocol, it’s normal to experience some adjustment period during which your body adapts to the new eating pattern. However, if you’re not patient and persistent enough, you might give up too soon and miss out on the long-term benefits of OMAD. To avoid this mistake, you should:

Give yourself at least two to four weeks to adapt to OMAD and establish a routine that works for you.
Gradually increase your fasting window or decrease your eating window over time if you feel comfortable and see progress.

Monitor your hunger, energy, and mood levels during your fasting and eating windows and adjust your food choices and timing accordingly.
Stay motivated by tracking your weight, body measurements, or non-scale victories such as improved mood, energy, or sleep quality.

You’re stressed or sleep-deprived, which can hinder weight loss

Stress and sleep deprivation are two common factors that can interfere with your weight loss efforts, regardless of your diet or exercise regimen. When you’re stressed or sleep-deprived, your body produces more cortisol, a stress hormone that can increase inflammation, insulin resistance, and crashes, which can hinder your weight loss progress. To ensure that you’re getting enough protein and fiber in your OMAD meal, you should:

Aim for a protein intake of at least 0.8 grams per kilogram of body weight per day.
Include protein-rich foods such as chicken, fish, tofu, eggs, or legumes in your OMAD meal.

Add fiber-rich foods such as vegetables, fruits, nuts, and seeds to your OMAD meal to increase satiety and support digestive health.
Consider taking supplements such as whey protein, collagen, or psyllium husk if you struggle to meet your protein or fiber needs through food alone.

You’re drinking calorie-containing beverages outside your OMAD meal

Stick to non-caloric beverages such as water, unsweetened tea or coffee, herbal tea, or sparkling water during your fasting window.
Avoid drinking calorie-containing beverages before or after your OMAD meal, as they can add unnecessary calories and blunt your hunger and satiety signals.

If you must drink calorie-containing beverages, choose lower calorie options such as light beer, wine, or spirits, and limit your intake to one or two servings per week.

Set clear boundaries for your fasting and eating windows and stick to them consistently.

Stay busy or distracted during your fasting window with activities such as exercise, work, hobbies, or socializing.

If you feel too hungry or thirsty during your fasting window, drink water or non-caloric beverages and remind yourself of your weight loss goals and progress.

Stay motivated by tracking your weight, body measurements, or non-scale victories such as improved mood, energy, or sleep quality.

You’re stressed or sleep-deprived, which can hinder weight loss

Stress and sleep deprivation are two common factors that can interfere with your weight loss efforts, regardless of your diet or exercise regimen. When you’re stressed or sleep-deprived, your body produces more cortisol, a stress hormone that can increase inflammation, insulin resistance, and store more fat. Additionally, lack of sleep can disrupt your circadian rhythm, which can affect your hunger and satiety hormones and increase your cravings for high-calorie foods. To overcome these barriers, you should:

Practice stress-reducing techniques such as meditation, deep breathing, yoga, or journaling to manage your stress levels and cortisol production.
Aim for at least seven to eight hours of uninterrupted sleep every night and avoid stimulating activities or screens before bedtime.
Create a relaxing bedtime routine that helps you unwind and prepare for sleep, such as taking a warm bath, reading a book, or listening to calming music.

Seek professional help if you struggle with chronic stress or sleep disorders that affect your quality of life.

You’re not incorporating physical activity into your routine

While OMAD can help you lose weight by creating a calorie deficit, incorporating physical activity into your routine can enhance your weight loss results and improve your overall health. Exercise can increase your metabolism, burn more calories, reduce your body fat percentage, and preserve your muscle mass. Additionally, exercise can boost your mood, energy, and self-esteem, which can motivate you to stick to your OMAD plan. To make the most of your workouts, you should:

Choose a type of exercise that you enjoy and can sustain in the long term, such as walking, running, cycling, swimming, or strength training.
Aim for at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity exercise per week, as recommended by the World Health Organization.
Incorporate resistance training at least two days per week to maintain or increase your muscle mass, which can boost your metabolism and improve your body composition.

Listen to your body and adjust your exercise intensity and duration according to your fitness level and goals.

Conclusion

OMAD can be a powerful tool for weight loss and health improvement, but it’s not a magic bullet that works for everyone. If you’re not losing weight with OMAD, you might be making some common mistakes such as not eating enough protein or fiber, drinking calorie-containing beverages, snacking or grazing during your fasting period, not giving yourself enough time to adjust to OMAD, being stressed or sleep-deprived, or not incorporating physical activity into your routine. By identifying and addressing these issues, you can optimize your OMAD plan and achieve your weight loss goals while improving your overall well-being.
