OMAD, or 'one meal a day', is a form of intermittent fasting that involves eating just one large meal per day and fasting for the remaining 23 hours. It is often combined with the keto diet, which is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. Both OMAD and keto are popular weight loss strategies, and when combined, they can lead to significant weight loss results. While there is limited scientific data on the effectiveness of OMAD specifically, studies have shown that intermittent fasting can lead to improved body composition, better insulin sensitivity, and reduced risk factors for heart disease. The combination of OMAD and keto can be an effective way to shift stubborn weight and easily maintain ketosis, but it is important to note that this combination may not be suitable for everyone and should be done under the guidance of a healthcare professional.

Weight loss results vary depending on factors like starting weight, calorie intake, activity level, and overall health
Weight loss is a complex issue that is influenced by many factors, and results will vary from person to person. While calorie intake, activity level, and overall health are important considerations, other factors also play a role in determining weight loss outcomes.
One's starting weight and body composition can impact weight loss results. People with more weight to lose tend to see faster initial results. Additionally, calorie intake during the eating window matters. Even when following an OMAD diet, consuming too many calories can hinder weight loss. It is important to maintain a mild caloric deficit, as a deep caloric deficit may not be sustainable.
Physical activity levels can significantly impact weight loss. Exercise can boost metabolism and burn more calories, leading to faster weight loss. However, it is worth noting that the type of activity and duration also matter. For example, 150 minutes of moderate-intensity aerobic activity per week can provide various health benefits, including reduced risk for type 2 diabetes, heart attack, and stroke.
Overall health and underlying medical conditions can also affect weight loss. Certain medical conditions, such as an underactive thyroid, polycystic ovary syndrome (PCOS), or hormonal changes, may hinder weight loss. Additionally, certain medications can impact weight loss, including those for diabetes, depression, epilepsy, birth control, and blood pressure regulation.
Other factors that may influence weight loss results include sleep, stress levels, age, race or ethnicity, family history and genes, lifestyle habits, and socioeconomic factors, such as access to healthy foods and safe places to exercise.
While OMAD can lead to weight loss, it is not suitable for everyone and should be approached with caution. It is always recommended to consult with a healthcare professional or registered dietitian before starting any new diet to ensure it aligns with your specific needs and goals.

OMAD is an extreme form of intermittent fasting that may not be suitable for everyone
OMAD, or 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 it has gained popularity as a weight loss and health improvement strategy, it is considered an extreme form of intermittent fasting that may not be suitable for everyone. Here are some reasons why OMAD may not be the best approach for everyone:
- Extreme Restriction: OMAD is a very restrictive diet that limits food intake to a one-hour window each day. This extreme restriction may not be feasible or healthy for everyone, especially those with certain medical conditions or nutritional needs.
- Nutritional Concerns: It can be challenging to consume all the necessary nutrients and calories in a single meal. This may lead to inadequate protein and calorie intake, potentially affecting overall health and energy levels.
- Hunger and Overeating: Lengthy fasting periods may result in severe hunger, leading to overeating and making it difficult to stick to a healthy diet. This can defeat the purpose of the diet and lead to unhealthy food choices.
- Digestive Issues: Eating a large meal after a long fast can cause digestive issues such as gas, bloating, and acid reflux. It may also be challenging for those with dietary restrictions or specific nutritional needs.
- Side Effects: OMAD can cause side effects such as fatigue, low energy, brain fog, and low blood sugar (hypoglycemia). These side effects can impact daily functioning and may be a concern for some individuals.
- Not Suitable for Everyone: OMAD is not recommended for individuals with a history of disordered eating or eating disorders or those prone to hunger pangs due to low blood sugar. It may also be unsafe for pregnant or breastfeeding individuals and those with certain medical conditions.
- Long-Term Sustainability: OMAD is not meant to be a long-term diet and may not be sustainable or practical for extended periods. It is important to consult with a healthcare professional before starting OMAD or any extreme diet to ensure it aligns with your specific needs and goals.

OMAD can lead to a calorie deficit, which is essential for weight loss
OMAD, or '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 daily fast can lead to a calorie deficit, which is essential for weight loss.
When following OMAD, an individual consumes their daily calories in a single sitting, typically during a 1-2 hour eating window. This naturally creates a calorie deficit, as most people tend to eat fewer calories in one meal than they would across multiple meals. A calorie deficit occurs when an individual consumes fewer calories than they burn, and it is necessary for weight loss.
The amount of weight lost while following OMAD can vary depending on various factors, including starting weight, calorie intake during the eating window, activity level, and overall health. On average, individuals following OMAD can lose between 4-8 pounds (1.8-3.6 kg) in a month. However, this can range from mild weight loss of 1-3 pounds to significant weight loss of more than 8 pounds.
It is important to note that a mild caloric deficit can be a sustainable weight loss strategy, while a deep caloric deficit may not be. Additionally, consuming too many calories during the OMAD eating window can hinder weight loss. Therefore, it is crucial to find a balance and ensure that the single meal is within the individual's daily caloric needs.
OMAD can be an effective approach to weight loss, as it allows individuals to create a calorie deficit while still enjoying their favourite foods. However, it may not be suitable for everyone, and it is important to consult with a healthcare professional before starting any new diet.

OMAD may improve metabolic health, increase focus and energy, and reduce inflammation
OMAD, or 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 23:1 method is the longest form of time-restricted eating and can be a powerful tool for weight loss and improving metabolic health.
Improving Metabolic Health
OMAD may improve metabolic health by increasing insulin sensitivity, reducing sugar cravings, decreasing blood sugar levels, lowering triglycerides, and increasing good cholesterol (HDL). This can benefit overall metabolic health and potentially reduce the risk of type 2 diabetes and heart disease. OMAD may also help reduce hyperinsulinemia, control diabetes, and improve metabolic syndrome.
Increasing Focus and Energy
Some people claim that OMAD enhances mental clarity and focus, as well as reducing feelings of fatigue and boosting energy levels. This is attributed to the body entering a state of ketosis during prolonged fasting periods. Ketosis is a metabolic state where the body burns fat instead of sugar as a fuel source, and it has been shown to increase energy levels and enhance mental focus.
Reducing Inflammation
Following an intermittent fasting schedule like OMAD may lower levels of inflammatory markers in the body. This is because, during fasting, the body diverts its energy towards repair and detoxification, cleaning up dead cells and debris. Lowering inflammation through OMAD may be beneficial for reducing chronic inflammation, which is associated with various health conditions like arthritis, asthma, and metabolic diseases.

Combining OMAD with the Keto diet can help maintain ketosis and burn fat
Combining OMAD with the Keto diet can be an effective strategy for maintaining ketosis and burning fat. OMAD, or One Meal a Day, is a form of intermittent fasting where individuals consume their daily calories in a single sitting, typically within a one to two-hour window. This extended fasting period can promote ketosis, a metabolic state where the body burns fat for energy instead of carbohydrates.
The Keto diet, or Ketogenic diet, is a low-carb, high-fat diet designed to shift the body's metabolism from burning glucose to burning fat. By keeping carbohydrate intake low, the body is forced to use fat as its primary fuel source, leading to weight loss and improved metabolic health.
When OMAD and Keto are combined, several benefits can be observed:
Maintaining Ketosis
The extended fasting period of OMAD helps individuals stay in ketosis for longer periods. By restricting food intake to a single meal, the body relies primarily on fat for energy, promoting a deeper state of ketosis. This combination can be especially beneficial for individuals who have hit a weight loss plateau with the Keto diet alone.
Enhanced Fat Burning
Both OMAD and Keto are effective strategies for burning fat. OMAD encourages fat burning by extending the period of fasting, while Keto shifts the body's metabolism to favour fat as a fuel source. Together, they create a synergistic effect, accelerating fat loss and promoting weight management.
Time and Cost Efficiency
OMAD reduces the time spent on meal preparation, cooking, and cleanup. With only one meal to plan and prepare, individuals can save significant time and money on groceries. This simplicity can make it easier to stick to a Keto diet and achieve long-term results.
Improved Blood Sugar Control and Cholesterol
Combining OMAD with Keto can lead to improved blood sugar control and cholesterol levels. Intermittent fasting has been shown to lower blood glucose levels and improve insulin sensitivity. Additionally, a systematic review found that intermittent fasting and energy-restricted diets improved total cholesterol and triglyceride levels.
Potential Drawbacks
While combining OMAD with Keto can be beneficial, it is important to consider potential drawbacks. OMAD may cause digestive issues, such as feeling overly full followed by diarrhea, due to the large amount of food consumed in a single sitting. Additionally, there is a risk of consuming excess carbohydrates during the eating window, which can hinder ketosis. It is crucial to ensure adequate nutrient intake and monitor blood sugar levels to avoid hypoglycemia, especially for individuals new to Keto and fasting.
