OMAD, or “one meal a day”, is a type of intermittent fasting. On OMAD, you eat all your calories in one sitting. This daily fast lasts about 23 hours, with the 24th hour dedicated to eating. OMAD is not a calorie-restrictive diet. For most people, this means consuming between 1300 and 2000 calories per day. However, some sources suggest that the number of calories you consume on OMAD should be based on your regular intake. For example, if you typically eat 2000 calories, you should aim for that number in your one meal.

What You'll Learn
OMAD calories depend on your regular intake
OMAD, or "one meal a day", is a type of intermittent fasting. It is a highly restrictive diet, as it involves eating only one meal per day and fasting for the remaining 23 hours. While OMAD does not require calorie counting, it is important to ensure your one meal contains enough calories to meet your body's needs.
The number of calories you should consume during your daily OMAD meal depends on your regular intake and body's requirements. For most people, this ranges from 1,300 to 2,500 calories per day. However, it is crucial to ensure you are meeting your caloric needs, especially if you are physically active or have a higher metabolism.
If you typically consume 2,000 calories per day, your OMAD meal should aim for a similar caloric intake. This may be challenging, as eating such a large volume of food in one sitting can be uncomfortable and may disrupt your digestion. Therefore, it is essential to listen to your body and adjust your calorie intake accordingly.
While OMAD can be an effective way to reduce overall calorie consumption, it is not a calorie-restrictive diet. Restricting your calories too much can be unhealthy and unsustainable. A mild caloric deficit of around 10% is generally considered a safe and effective approach for weight loss.
Additionally, the type of calories you consume is crucial. Selecting fatty whole foods, especially from animal sources, will provide optimal fuel for your body, keep you satiated during the fasting period, and protect against consuming too few calories. A low-carb, high-fat ketogenic diet pairs well with OMAD, as it can help curb cravings and provide steady energy during the fast.
It is important to note that OMAD may not be suitable for everyone. It can be challenging to meet your caloric and nutritional needs with just one meal, especially if you have a higher calorie requirement. Additionally, consuming a large volume of food in one sitting can be uncomfortable and may cause digestive issues for some individuals.
Before starting OMAD or any other restrictive diet, it is always recommended to consult with a healthcare professional to ensure it is safe and appropriate for your individual needs and health status.

OMAD is not a calorie-restrictive diet
OMAD, or "one meal a day", is an extreme form of intermittent fasting. It involves eating only one meal per day, typically within a one-hour window, and fasting for the remaining 23 hours. While this diet can lead to weight loss due to reduced calorie intake, it is not primarily a calorie-restrictive diet.
The OMAD diet is more about time restriction than calorie restriction. The key rule is to consume all your daily calories in one large meal, preferably during the daytime. This typically results in a mild caloric deficit, which can be an effective strategy for sustainable weight loss. However, OMAD does not impose strict calorie limits or restrictions on the types of food consumed.
The focus of OMAD is on the timing of meals rather than the number of calories consumed. This sets it apart from traditional calorie-restrictive diets, which emphasize reducing calorie intake at each meal. While some OMAD practitioners may aim for a specific calorie target, such as their regular intake or a mild deficit, it is not a core requirement of the diet.
The flexibility of OMAD regarding calorie intake is both a benefit and a potential drawback. On the one hand, it allows individuals to eat until they are satisfied without strict calorie counting. On the other hand, it can lead to undereating or overeating, depending on the person. It may be challenging to consume enough calories in one meal to meet metabolic needs, especially for those with higher caloric requirements.
In summary, while OMAD can lead to reduced calorie intake and weight loss, it is not primarily a calorie-restrictive diet. It emphasizes time restriction and allows for flexible calorie consumption within the one-meal framework.

OMAD calories are about quality, not quantity
OMAD, or "one meal a day", is an extreme form of intermittent fasting. It involves eating all your calories for the day in a single meal, and then fasting for the remaining 23 hours.
While OMAD can be an effective way to reduce calorie intake, it is not a calorie-restrictive diet. The focus is on consuming enough calories to feel satiated and energized, which is typically between 1,300 and 2,000 calories per day. However, the key to OMAD is not the quantity of calories, but their quality.
The type of calories consumed is crucial to the success of OMAD. Fatty whole foods, mostly from animal sources, are recommended as they provide optimal fuel for the body, help to curb hunger during the fasting period, and protect against consuming too few calories. This approach aligns with a low-carb, high-fat ketogenic or carnivore diet, which can enhance the benefits of intermittent fasting.
When following OMAD, it is important to ensure your meal is nutritionally balanced and includes a variety of macro and micronutrients. This can be challenging, as it may be difficult to consume a full day's worth of calories in a single meal. Therefore, OMAD is not just about calorie quantity but also about calorie quality to ensure your body receives the nourishment it needs.
Additionally, OMAD may not be suitable for everyone. It can be difficult to get enough calories, especially for those with higher metabolic needs or those who engage in regular intense workouts. It is important to listen to your body, and if OMAD is causing negative side effects, it may be necessary to adjust or try other forms of intermittent fasting.
In conclusion, the success of OMAD depends more on the quality of the calories consumed rather than solely on their quantity. A well-formulated, nutritionally balanced meal plan that includes fatty animal foods, healthy fats, and low-toxin fruits and vegetables is key to a successful and sustainable OMAD approach.

OMAD calories should be from fatty whole foods
OMAD, or "one meal a day", is a type of intermittent fasting where you eat all your calories in one sitting. This usually amounts to between 1,500 and 2,500 calories or more, depending on your body weight, size, and health goals.
While OMAD is not a calorie-restrictive diet, it can be challenging to consume more than 2,000 calories in a single meal. Therefore, the key to OMAD calories is not so much about how many calories, but what kinds of calories.
Selecting fatty whole foods, mostly from animal sources, will provide optimal fuel for your body, keep you satiated during the fasting period, and protect against consuming too few calories. This is especially important as chronic calorie restriction, along with consuming large percentages of calories from high-carb food sources, can damage your immune system and thyroid function and trigger hormone responses that make losing weight more difficult.
A sustainable OMAD macros breakdown resembles that of a low-carb, high-fat ketogenic and carnivore diet. This means getting 75-80% of your calories from fat, 15-20% from protein, and 5-10% from carbs.
- Ruminant meats like steak, lamb, and bison
- Seafood including oysters and salmon roe
- Fatty fish like salmon, mackerel, and anchovies
- Organ meats like liver, kidney, and bone marrow
- Healthy fats like butter, tallow, ghee, and coconut oil
- Low-toxin fruits and vegetables like avocado and berries

OMAD calories should be 1,800 to 2,500 per meal
OMAD, or "one meal a day", is a type of intermittent fasting. On OMAD, you eat all your calories for the day in one sitting. This is usually a large meal, and it can be challenging to fit all your calories into this one meal.
The number of calories you should eat on OMAD depends on your regular intake. If you typically eat 2000 calories a day, you should aim for that number in your one meal. However, you should ensure that you are not eating fewer than 1200 calories in your OMAD meal. For most people, this number is between 1300 and 2000 per day.
If you are aiming to lose weight, you may want to eat a mild caloric deficit of around 10% fewer calories. This could mean eating between 1800 and 2500 calories in your OMAD meal.
It is important to note that OMAD is not a calorie-restrictive diet. The key is to eat until you feel satiated and energized. OMAD can be an effective way to reduce overconsumption of calories because it is difficult to consume more than 2000 calories in a single meal.
When planning your OMAD meal, it is important to ensure that it is nutritionally balanced and includes all the necessary food groups. This may include whole grains, lean protein, vegetables, fruit, and low-fat or fat-free dairy.
Some people find that combining OMAD with a keto diet works well for them. Keto is a low-carb, high-fat diet that can help curb cravings and reduce hunger during the long fasting period of OMAD.
Overall, OMAD can be a safe and effective way to lose weight and improve your health, but it is important to ensure you are getting adequate calories and nutrition during your eating window.
