During the first few days on the OMAD diet, you may experience low energy, dizziness, nausea, and hunger pangs. These side effects are considered normal, but if they persist, it may be a sign to stop the diet. To prepare for OMAD, it is recommended to have prior fasting experience and get your medical condition checked.

What You'll Learn
OMAD is a type of intermittent fasting
OMAD, or "one meal a day", is a type of intermittent fasting. It involves eating just one meal per day and fasting for the remaining 23 hours. This makes it a very restrictive nutrition system, and it is considered more extreme than other forms of intermittent fasting.
Intermittent fasting involves restricting your eating periods to certain times, usually with the aim of burning more fat and losing weight. OMAD is similar to the Warrior Diet, another form of intermittent fasting, which has a 20-hour fasting and a 4-hour eating window. However, OMAD typically involves eating within a much narrower period of 1-2 hours.
There is no fixed meal plan for OMAD, and you can eat whatever you want during your eating period. However, it is important to eat a nutritionally balanced meal with plenty of healthy proteins, fats, vegetables, and leafy greens. Your one meal should contain at least 1,200 to 1,500 calories to ensure you are consuming a good range of micronutrients and fuelling your body properly.
Some people choose to have their meal in the morning, while others prefer to eat later in the day. However, it is not recommended to eat your single meal late at night as this can cause digestive problems and disrupt your sleep. OMAD can be combined with other diets such as keto, vegetarian, or Mediterranean.

You should eat 1,200 to 1,500 calories in your one meal
OMAD, short for "one meal a day", is a type of intermittent fasting that involves eating one large meal per day and fasting for the remaining 23 hours. While OMAD can be effective for weight loss, it is a very restrictive nutrition system. Before starting OMAD, it is important to have prior fasting experience and to get your medical condition checked.
The OMAD diet can put your body in a calorie deficit, which can lead to weight loss. However, it is important to ensure you are eating enough to meet your body's caloric requirements. Your one meal should contain at least 1,200 to 1,400 calories, as this is the minimum needed to consume a good range of micronutrients and fuel your body properly while enabling a safe rate of weight loss. This is equivalent to about 1,200 to 1,500 calories.
To break your fast healthily, focus on whole, nutritious foods. Include ample protein, healthy fats, and a variety of micronutrients. Examples include eggs, bone broth, green leafy vegetables, meat, and poultry. Avoid highly processed foods, as they are bad for your health.
It is important to note that OMAD may not be suitable for everyone. Dramatic intermittent fasting can increase health risks for people with underlying conditions such as heart disease. Additionally, long periods of fasting can negatively impact your energy levels, making it challenging to stay active and focus on tasks. If you experience negative side effects, consider quitting the OMAD diet.
Consulting a healthcare professional is the best way to determine if OMAD or any form of intermittent fasting is safe and effective for you. They can tailor an eating plan and schedule based on your needs, preferences, and medical history.

You may experience negative side effects
OMAD (one meal a day) is an extreme form of intermittent fasting, and as such, it can have negative side effects. The diet involves eating one large meal per day and fasting for the remaining 23 hours. While OMAD can lead to weight loss, it can also have detrimental effects on your mind and body.
Firstly, OMAD can cause a noticeable decline in your energy levels. This can make it difficult to stay active and exercise regularly. You may also experience an inability to concentrate, making it harder to focus on tasks, retain information, and perform at your best. This is because your body changes to using ketosis for burning fat instead of carbohydrates for energy. Extreme hunger and tiredness are common in the early stages of OMAD as your body adjusts to using energy stores throughout the day.
Secondly, OMAD can lead to lean muscle mass loss. This may not affect someone who is overweight to begin with, but a person at a healthy weight may notice a loss of muscle mass. Research on the likelihood of this while following OMAD is limited, but one study found that several months of intermittent fasting can cause a loss of 1-2kg of muscle.
Thirdly, OMAD may cause digestive problems, disrupt your circadian rhythms, and make it harder to fall asleep. This is especially true if you consume your one meal late at night.
Finally, OMAD can raise health risks for people with underlying conditions such as heart disease. One study found that people who followed a time-restricted eating pattern similar to OMAD were 91% more likely to die of cardiovascular disease. OMAD can also be dangerous for people with conditions such as kidney disease, diabetes, and cancer.

It can be cheaper than other diets
The OMAD diet, which stands for "one meal a day", is a type of intermittent fasting that involves eating one large meal per day and fasting for the remaining 23 hours. This diet can be cheaper than other diets because you are only eating one meal per day, which can result in lower food costs. For example, you may only need to spend around $10 per day on ingredients, which equates to approximately $300 per month. However, the total cost may vary depending on the type of food purchased and whether you choose organic options.
One of the benefits of the OMAD diet is that it can save you time in the kitchen. By only having to prepare one meal per day, you can free up time that would otherwise be spent cooking and planning meals. This makes it a convenient option for those with busy schedules or those who want a break from constant cooking.
While the OMAD diet can be cheaper and more time-efficient, it is important to consider the potential drawbacks. Firstly, it can be challenging to consume all the necessary calories and nutrients in a single meal. As a result, your body may not be getting the fuel it needs, leading to potential health issues such as chronic fatigue, hormonal imbalances, and poor immunity. Therefore, it is crucial to ensure that your one meal is highly nutritious and contains a good range of micronutrients, such as lean protein, healthy fats, and vegetables.
Additionally, the OMAD diet may not be suitable for everyone. It can lead to extreme hunger and tiredness, especially for those who are used to eating multiple meals and snacks throughout the day. It is also important to note that long periods of fasting can negatively impact your energy levels and concentration, making it difficult to stay active and focused on tasks.
Before starting the OMAD diet or any other dietary change, it is always recommended to consult a healthcare professional. They can provide tailored advice based on your individual needs and help determine if this diet is safe and effective for you.

It may be unsafe for people with underlying conditions
The OMAD (one-meal-a-day) diet is a form of extreme intermittent fasting. OMAD involves eating one large meal per day and fasting for the remaining 23 hours. While OMAD can lead to weight loss, it is a very restrictive nutrition system.
OMAD may be unsafe for certain groups of people. This includes people who are pregnant or nursing, under 18, or have an eating disorder or a history of disordered eating. Additionally, OMAD may be unsafe for people with underlying health conditions. Dramatic intermittent fasting, such as OMAD, can increase health risks for people with conditions such as heart disease. A 2024 study found that people who followed a time-restricted eating pattern similar to OMAD were 91% more likely to die of cardiovascular disease than those who followed a standard eating schedule. OMAD may also be unsafe for people with kidney disease, diabetes, or cancer. If you have diabetes, a large meal may lead to an unhealthy blood sugar spike.
If you are considering OMAD, it is important to consult a healthcare professional, such as a registered dietitian or nutritionist. They can review your medical and family history and let you know if OMAD is safe and effective for you. It is also important to be mindful of your nutritional intake while on OMAD. Your one meal should contain at least 1,200 to 1,400 calories and a variety of nutrients to fuel your body properly.
