Dieting has evolved beyond the simplistic approach of merely consuming boiled foods. In today's world, factors such as the timing and frequency of meals, in addition to the types of food consumed, significantly influence dietary outcomes. Among the various weight loss strategies, two particularly restrictive diets—the OMAD diet and the monotrophic diet—represent contrasting approaches. The OMAD diet permits the consumption of a substantial meal once per day, requiring fasting for the remainder of the day. Conversely, the monotrophic diet advocates for the intake of a single type of food throughout the day. Each of these diets presents unique advantages and disadvantages. Which option is superior? Let us explore this further.

What is the OMAD Diet?

The OMAD diet, similar to intermittent fasting, is a dietary approach that restricts food intake to a specific time frame each day. In this regimen, individuals refrain from eating for 23 hours and then consume all their daily calories in a single meal. This method permits the consumption of only one meal per day. It is thought that this practice may facilitate weight loss, as prolonged fasting periods lead to reduced insulin production, a hormone essential for metabolizing sugars derived from carbohydrates. Nevertheless, the body still requires energy, prompting fat cells to release stored energy, ultimately resulting in weight loss.

What is the monotrophic diet?

A diet that has gained attention recently is the monotrophic diet. This approach is characterized by its restrictive nature, as individuals are limited to consuming only one type of food or food group during each meal or throughout the day, as noted by Veena. For example, one might choose to eat solely fruits, vegetables, or meat for an entire day. While this method may lead to short-term weight loss due to reduced calorie intake, it fails to supply essential nutrients, making it unsustainable and potentially detrimental over time. Experts generally recommend a well-balanced diet that includes a variety of nutrients.

Benefits of the OMAD diet

Consuming a single meal each day, as permitted by the OMAD diet, offers several benefits. Below are how it can positively impact your body.

1. Helps to burn fat

The OMAD diet has the potential to facilitate fat loss. Research published in the journal Frontiers in Physiology indicated that consuming one meal per day in the evening can lead to a reduction in body weight. Furthermore, the study noted that this dietary approach did not adversely affect the physical performance of the participants. Consequently, the OMAD diet may assist in weight loss, and despite the limitation of eating only once daily, individuals are unlikely to experience fatigue.

2. Helps to improve metabolism

The OMAD diet, which involves consuming food only once a day, can be advantageous for your metabolism. Research published in The American Journal of Clinical Nutrition indicates that dietary restrictions, like those associated with the OMAD approach, are particularly beneficial due to their impact on energy metabolism, notably by enhancing insulin sensitivity. Furthermore, fasting promotes the secretion of human growth hormone (HGH), which aids in preserving muscle mass, facilitates fat metabolism, and enhances overall metabolic health.

3. Makes you more alert

Some individuals report enhanced focus and vitality due to stable blood sugar levels and a reduced digestive load, according to Veena. During fasting, the body produces norepinephrine, a neurotransmitter that enhances alertness, concentration, and energy. Additionally, prolonged periods without food, such as in the One Meal a Day (OMAD) diet, stimulate the production of ketones, which act as a highly effective energy source for the brain. Furthermore, daytime fasting triggers the release of orexin-A, a chemical that contributes to increased alertness.

Benefits of the monostrophic diet

The monotrophic diet can result in short-term weight loss through lowered calorie consumption. Here is how it can help you:

1. Easier to digest

In contrast to the OMAD diet, this approach involves consuming the same foods several times throughout the day. This practice facilitates the digestive process and may contribute to a reduction in bloating or indigestion. According to Veena, "The diet enables individuals to recognize food intolerances by eliminating specific food groups while promoting mindful eating and supporting digestion."

2. Reduces hunger cravings

In this dietary approach, you are limiting your food options. This strategy can assist in managing hunger pangs and curbing emotional eating. When we indulge in a diverse array of foods, many of which may be rich in sugar and salt, our brain's reward system can become overstimulated, leading to heightened cravings. In contrast to the OMAD diet, where you consume the same food repeatedly, this method alleviates sensory overload. Consequently, it aids in diminishing the urge for highly palatable foods.

3. Helps in weight loss

The monotrophic diet, similar to the OMAD diet, can facilitate weight loss. By consuming a single type of food, individuals may find it easier to reduce their overall intake, potentially resulting in weight reduction. Nonetheless, the effectiveness of this diet is contingent upon the specific food choices made. For instance, if one opts for vegetables, this approach is likely to promote weight loss. Conversely, if the repeated food is high in sugar and calories, it may lead to weight gain instead. Further research is required to explore this topic comprehensively.

4. Easier to prepare

In contrast to the OMAD diet, which involves consuming a variety of foods in a single sitting, this approach focuses on eating the same item consistently. Veena notes that this makes meal preparation significantly more straightforward. The process of planning and preparing meals is simplified, eliminating the need to spend time deliberating on what to cook. For individuals with a hectic lifestyle, this method is particularly advantageous.

Risks of following the OMAD diet

Adopting a one-meal-per-day approach, as practiced in the OMAD diet, carries certain risks:

This dietary pattern may result in deficiencies in essential nutrients, reduced energy levels, and a decline in metabolic function due to prolonged fasting.

It may also provoke intense hunger, which could lead to overeating or the selection of unhealthy food options during the single meal.

Additionally, this eating regimen can negatively impact digestion, increase levels of stress hormones, and, in some cases, disrupt blood sugar regulation. Research published in the journal Metabolism indicates that the absence of calorie restriction in the single meal permitted by the OMAD diet may contribute to elevated fasting glucose levels.

Furthermore, a long-term commitment to the OMAD diet may result in muscle deterioration and difficulties in achieving a well-rounded intake of vital vitamins and minerals. Therefore, it is crucial to seek medical advice before embarking on such a dietary plan.

Risks of following the monostrophic diet

The monotrophic diet poses several risks. The primary concern is the potential for nutrient deficiencies resulting from its lack of variety. This limitation may lead to insufficient intake of essential vitamins, minerals, and proteins. Consequently, individuals may experience muscle mass loss, weakened immune function, and decreased energy levels, according to Veena. Additionally, the highly restrictive nature of this diet can trigger cravings and subsequent overeating. Prolonged adherence to such a diet may also slow down metabolism and adversely affect overall health.

What does a balanced OMAD diet plan look like?

"A balanced OMAD meal should be nutrient-dense, providing adequate protein, healthy fats, fibre, vitamins, and minerals," says Veena

Macronutrient breakdown

• Protein: 30–40% of total calories should be from protein-rich foods. This is for muscle maintenance and satiety
• Healthy fats: 30–35% of foods must be healthy fats. This helps in sustained energy and hormone balance.
• Complex carbohydrates: 25–30% needs to come from complex carbs. This is for fibre and steady energy release.
• Micronutrients: Prioritise vitamins (B12, C, D, and E) and minerals (magnesium, potassium, and iron)

What does a balanced monotrophic diet look like?

We can rotate each food group in this diet and make one fruit group in a day.

Example:

• Day 1: Fruits
• Day 2: Vegetables
• Day 3: Proteins
• Day 4: Low glycemic index grains

OMAD diet vs monotrophic diet: Which one is better?

According to Veena, the OMAD diet is generally a more advantageous option for weight loss compared to the monotrophic diet, as it allows for a more balanced intake of nutrients within a single meal, thereby preventing severe deficiencies. Additionally, OMAD may enhance insulin sensitivity and promote fat loss while maintaining a degree of food flexibility. Conversely, the monotrophic diet is more restrictive and often leads to nutrient imbalances and unsustainable eating habits.
