OMAD stands for “one meal a daily” and is a form of extreme intermittent fasting that has gained a lot of attention in the nutrition industry.
The OMAD diet is a fasting regime that requires you to eat one large meal in one hour, and then fast for the rest of the 23.
Although the OMAD diet does not restrict calories, it has many benefits. Autophagy is a cellular process that removes waste from the body. This helps to improve health and longevity.
Understanding the risks and benefits of OMAD can help you make the right decision about how to incorporate it into your life.
Although OMAD is a extreme form of intermittent fasting it is actually very simple. Eat one large meal per day within one hour and then fast for the remaining 23 hours.
Other than that, the only rule in OMAD is to keep the same daily schedule.
This means that if you decide to eat between 3 and 4 p.m. (one the most common eating times for people following OMAD), this will be your continuing eating window.
The OMAD diet outlines what foods to eat and when they should be eaten. However, it doesn’t give any specific guidelines about what to eat. There is no strict guideline for calorie intake or breakdown of macronutrients.
Technically, you are following OMAD as long as you stick to your eating time.
However, it is always a good idea, just like any diet, to make healthy choices about what you eat.
Amy Shah, M.D. Amy Shah, M.D., advises that you avoid carb-loaded foods and sugary drinks because they can cause a blood sugar rollercoaster, increasing insulin levels, and making it even more hungry.
Shah says that refined carbs are not only a problem for the moment but also make it difficult to fast the next day because hunger hormones like ghrelin will rise and you’ll feel hungryrier. Try to eat lean proteins, healthy oils, and lots of vegetables during your hour-long eating window.
Summary
The OMAD diet is a fast that involves eating one large meal per day for one hour.

The OMAD diet has many benefits
OMAD, which is a type of intermittent fasting, is thought to have many of the same benefits but a shorter eating window. These are just a few of the benefits that eating one meal per day can bring.
The greatest benefit of the OMAD diet? It’s simplicity. You only eat once per day and there are no rules as to what you should eat. This means that there isn’t much meal prep or planning required.
You only need to think about when you should break your fast, and how to keep that schedule going on the days that you include OMAD.
Summary
One of the simplest forms of fasting is the OMAD diet. One meal per day is all you can eat in a given time period. There are no other rules.

This may help you manage your weight
You can lose weight with any type or frequency of calorie restriction. However, one study compared intermittent fasting to daily, regular calorie restriction to determine the effects on body composition.
Researchers found that intermittent fasting, which is more effective than calorie restriction, may be more effective in weight loss. It also helps to retain lean muscle mass and body mass.
A small controlled study of 32 participants showed that even if overall calories were not restricted, eating all calories in one meal per day resulted in greater body fat loss.
Notable: Researchers from the study found that one meal per day could lead to slightly higher blood pressure and cholesterol levels, although it did reduce cortisol levels.
Summary
Research has shown that eating all calories in one meal per day can result in greater weight loss than fasting.

It could improve your metabolic health
Even more amazing is the fact that intermittent fasting may improve several health indicators, even without weight loss.
Researchers conducted a small study in which pre-diabetic males were asked to follow different fasting times, but still gave them enough food to maintain their weight.
The men saw improvements in their insulin levels, insulin sensitivity and beta cell response after 5 weeks. They also noticed a decrease in blood pressure and oxidative stress levels.
A small study was done on 10 men with type 2 Diabetes who were taking metformin. This is one of the most common diabetic medications.
Two weeks later, the men’s blood sugar control was better than it was when they started the study.
Summary
Different forms of fasting have been shown to improve insulin levels and blood pressure as well as manage stress.

It can improve your mood
Intermittent fasting doesn’t just have physical benefits; it also has mental benefits.
A study found that serotonin, a mood-boosting neurotransmitter, can be increased by prolonged fasting. It can also increase natural opioid and endocannabinoid production.
Summary
Studies have shown that serotonin availability can be increased by prolonged fasting, which is a mood-enhancing neurotransmitter in your brain.
5.
It could increase longevity
Although most of the research into intermittent fasting and longevity was done on animals, the results are encouraging.
One 2019 review suggests that fasting, as a way to reduce your food intake, can reverse or slow down aging.
One of the longest-running animal studies on rats found that prolonged fasting could extend their lives by up to 80 percent.
The effects of fasting depend on many factors, including age, gender, diet, and genetics.
There is some research that shows intermittent fasting can be more effective than less intense forms, but there aren’t many studies to show whether eating longer periods of time without eating (as in OMAD) offers additional benefits.
Summary
Studies on animals and humans have shown that prolonged fasting can improve your life expectancy.
Are there any people who shouldn’t try the OMAD diet.
As with all forms of intermittent fasting there are people who should not try OMAD.
OMAD may not be sufficient for Type 1 diabetes patients. This is especially true in the first phase of your body’s adjustment.
An OMAD diet for women is not strictly prohibited, but women are more sensitive to hormonal effects of fasting due a protein called Kisspeptin.
If you are a woman considering OMAD or any other type of fasting, you should be aware of the possible concerns for women. To determine the best plan for you, talk to your doctor.
You should not add stressors like OMAD to your life if you are currently experiencing a lot of stress or difficulty managing daily life.
If you are pregnant or nursing, it’s a good idea not to follow restrictive eating plans such as the OMAD diet. It’s not for children or young adults.
Summary
If you are suffering from Type 1 diabetes, or are breastfeeding, avoid OMAD. OMAD should be avoided if you have a history or eating disorder.
Tips to start an OMAD Diet
There are simple tips and tricks to help you get started with an OMAD diet even if you don’t fit into one of these categories.
Research shows that there is no set time for OMAD meals. However, it may be better to get all your calories in the morning.
One study found that eating calories after 5 p.m. caused a significant rise in C-reactive protein (or CRP), which is an inflammatory marker linked to heart disease, breast cancer, and other diseases.
Taz Bhatia M.D. is a board-certified doctor specializing integrative medicine. She advises against jumping into OMAD.
Although you might feel great during these brief fasts, it is possible to find that fasting doesn’t work for your needs.
To find a plan that works best for you, gradually increase the frequency and duration of your fasting over a period of several weeks to one month. This will allow your body to adjust.
Start with the 16:8 plan if you are new to intermittent fasting. Then, work your way up to OMAD.
These are some other tips that can help you get started and increase your chances for success:
You will only be eating one meal per day so you want to ensure you get as many nutrients as you can.
You should be focusing on lean proteins, healthy oils, and lots of different kinds of vegetables. Don’t eat the exact same thing every day.
Variating your food choices can optimize your nutrient intake.
2.
Reduce the amount of carbs in you diet
This balances blood sugar and hunger hormones. It can help you stick to a fasting plan.
3.
Your fasting time should be adjusted accordingly
You can eat in one hour and fast for 23. It doesn’t matter if it takes you 90 minutes to eat or two hours, and that you fast for 22 hour.
The major goal is to stick to one nutritionally-balanced meal per day and eat around the same time daily.
Summary
Start slow and do a shorter fast to see how you feel before you jump into OMAD. To ensure you get as many nutrients possible, make sure you eat plenty of lean proteins, healthy oils, and vegetables.
What length should you keep following OMAD for?
The OMAD diet doesn’t provide a long-term solution. This is a quick “refresher” you can use once or twice a week, or whenever your body and digestive system needs it.
Although there are no strict guidelines regarding how long you should be following OMAD, it is important to listen to your body to determine if any changes need to be made.
Summary
The OMAD diet does not provide a permanent solution to your dietary problems. You can use it whenever your body feels like it needs a break. To make sure it’s right for you, listen to your body.
The OMAD diet, which is a more severe form of intermittent fasting, requires that you abstain for 23 hours from eating and eat all calories within a 1-hour window.
It seems to have many of the same health benefits that other forms of intermittent fasting such as weight loss, better mood, balanced blood sugar levels, and improved metabolism.
It’s not right for everyone. You should avoid OMAD (and any type of intermittent fasting) if you have Type 1 Diabetes or are suffering from chronic stress.
If you decide to give OMAD a try, you should ease into it slowly over several weeks. Also, make sure to regularly check in with your body and adjust based on how you feel.
