Hair loss is a common concern among both men and women. Many people experience hair loss at some point in their lives, and it can be caused by a variety of factors. One diet that has recently gained popularity is the OMAD diet, which stands for One Meal A Day. However, there are some concerns that this diet may be linked to hair loss. In this article, we will explore the facts and myths surrounding the link between OMAD and hair loss.

What is OMAD?

OMAD is a type of intermittent fasting where a person only eats one meal a day. This meal typically includes all of the necessary macronutrients, such as protein, carbohydrates, and fat.

How it works

The idea behind OMAD is that by restricting the time frame in which a person eats, they can achieve weight loss and other health benefits. By eating only one meal a day, the body is forced to use stored fat as energy, which can lead to weight loss.

Benefits of OMAD

Some of the benefits of OMAD include weight loss, improved insulin sensitivity, and better digestion. It has also been shown to reduce inflammation in the body and improve brain function.

Risks of OMAD

While OMAD may have some benefits, there are also some risks associated with this diet. These risks include nutrient deficiencies, dehydration, and a decreased metabolism.

Causes of Hair Loss

Normal hair growth cycle

Before we dive into the link between OMAD and hair loss, it is important to understand the normal hair growth cycle. The hair growth cycle has three phases: anagen, catagen, and telogen.

Reasons for hair loss

There are many different reasons why a person may experience hair loss. Some of the most common causes include genetics, nutritional deficiencies, hormonal imbalances, and stress.


Genetics play a major role in hair loss. If a person has a family history of hair loss, they are more likely to experience it themselves.

Nutritional deficiencies

Nutritional deficiencies, particularly of iron and protein, can lead to hair loss. This is because these nutrients are essential for hair growth.

Hormonal imbalances

Hormonal imbalances, particularly of thyroid hormones and sex hormones, can also lead to hair loss. This is because these hormones play a role in regulating hair growth.


Stress can also contribute to hair loss. This is because stress can disrupt the hair growth cycle and lead to increased shedding.

Understanding the Link between OMAD and Hair Loss

Hair loss is a common problem that affects many people, especially as they age. There are many factors that can contribute to hair loss, including genetics, nutritional deficiencies, hormonal imbalances, and stress. However, some people believe that intermittent fasting, such as OMAD, can also lead to hair loss. So, is there a link between OMAD and hair loss?

The effect of restricted calorie intake on hair growth

One possible reason for hair loss with OMAD is the effect of restricted calorie intake on hair growth. When you eat less food, your body has fewer nutrients to use for hair growth. This can lead to weaker hair follicles, which can eventually result in hair loss.

The role of Micronutrients in hair health

Micronutrients, such as vitamins and minerals, are essential for hair health. For example, biotin is a B vitamin that is necessary for healthy hair growth. Iron, zinc, and vitamin D are also important for hair health. If you are not getting enough of these micronutrients in your diet, it can lead to hair loss.

The impact of OMAD on hormone levels

OMAD can also have an impact on hormone levels, which can affect hair growth. For example, if you are not getting enough calories, your body may produce more cortisol, which is a stress hormone that can contribute to hair loss. Additionally, low levels of estrogen and progesterone can also lead to hair loss.

Research on OMAD and Hair Loss

There is limited research on the link between OMAD and hair loss. However, some studies have suggested that intermittent fasting can lead to hair loss. For example, a study in the Journal of Investigative Dermatology found that mice that were put on a calorie-restricted diet experienced hair loss.

Critiques of the research

Critics of the research argue that the study was conducted on mice and may not apply to humans. Additionally, they note that the mice in the study were on a severely restricted calorie diet, which is not the same as OMAD.

Implications for the link between OMAD and hair loss

While there is limited research on the link between OMAD and hair loss, it is clear that nutrition plays a crucial role in hair health. If you are not getting enough micronutrients or calories, it can lead to hair loss. Therefore, it is essential to ensure that you are getting enough nutrients and calories while doing OMAD.

Preventing Hair Loss with OMAD

Now that we’ve covered the potential risks of hair loss when following the OMAD diet, let’s take a look at some strategies for preventing this side effect.

Balancing Macronutrients

While the OMAD diet is based on eating one meal a day, it’s still essential to make sure that meal contains a balance of macronutrients (carbohydrates, protein, and fat). By consuming all of your daily calories in one sitting, it can be challenging to meet the necessary macronutrient requirements. However, incorporating nutrient-dense foods like fruits, vegetables, and lean proteins can help ensure that you’re getting a balanced meal.

Ensuring Adequate Micronutrient Intake

In addition to macronutrients, it’s also essential to get enough micronutrients (vitamins and minerals) to support overall health and hair growth. Some micronutrients that are particularly important for hair health include vitamin D, iron, and biotin. To ensure adequate intake, consider incorporating a daily multivitamin or focusing on foods that are rich in these nutrients.


Drinking enough water is crucial for overall health and can also promote hair growth. Aim to drink at least eight glasses of water a day, and consider incorporating hydrating foods like watermelon, cucumbers, and citrus fruits into your OMAD meal.

Stress Management

As we discussed earlier, stress can contribute to hair loss. Therefore, incorporating stress management techniques like yoga, meditation, or deep breathing exercises can be beneficial.

Coping with Hair Loss

Unfortunately, if you do experience hair loss while following the OMAD diet, it can be challenging to cope with. However, there are some steps you can take to help manage the condition.

Hair Care Tips

Proper hair care is essential for overall hair health, even more so when experiencing hair loss. Consider using a gentle shampoo and conditioner, and avoid using heat tools or harsh chemicals on your hair.

Styling Options

While losing hair can be challenging, there are still many styling options available, such as wigs, hair extensions, and hats.

Medical Treatments

In some cases, medical treatments may be necessary to manage hair loss. Speak with your healthcare provider to discuss potential treatment options.

Other Potential Side Effects of OMAD

While hair loss is a significant concern for those following the OMAD diet, there are other potential side effects to be aware of as well.


Feeling dizzy or lightheaded can be a common side effect of OMAD, particularly when first starting the diet. This is because your body is adjusting to the reduced calorie intake. However, if dizziness persists, it’s essential to speak with a healthcare provider.


Because the OMAD diet involves eating all your daily calories in one meal, it can be challenging to maintain energy levels throughout the day. If you experience fatigue, consider incorporating foods that are high in protein and healthy fats into your meal.


Reduced calorie intake can also lead to constipation. To prevent this side effect, make sure you’re consuming enough fiber-rich foods and staying hydrated.

Muscle Loss

Because the OMAD diet involves reducing calorie intake, it’s possible to lose muscle mass along with fat. To combat this, consider incorporating strength training exercises into your routine.
