REGN-COV2 – Artificial "antibody cocktail" 

Recently a new drug was approved for use in COVID patients in India. Known as REGN-COV2, this new therapy is based on monoclonal antibodies targeting the SARS-CoV-2 virus responsible for COVID. So how does it work? And is there any evidence behind the treatment?

Monoclonal antibodies are made from components of the human immune system. When the human body recognizes a bacteria or virus in the body, the immune system recognizes and processes proteins on the surface of that bacteria or virus. This is presented to the adaptive immune system, and antibodies have produced that lock onto these surface proteins, neutralizing their function and also tagging them for destruction by other white blood cells.

If we identify antibodies capable of efficiently tagging and neutralizing a certain virus, we can identify the cell capable of producing that antibody, clone it and produce it in vast quantities. The antibodies produced from this cloned cell line will be able to target the virus at the same efficiency and have the same ability to neutralize the virus. Just like with vaccines, there is a risk of mutations developing, resulting in changes in the surface protein that reduce binding and neutralizing effects of the antibodies, allowing them to escape and continue to cause disease

REGN-COV2 uses two neutralizing antibodies (Casirivimab/imdevimab), in an effort to minimize the ability of a mutant virus to develop resistance against the antibody cocktail, as the virus would need to develop mutations canceling both antibodies out at once. These antibodies neutralize the receptor-binding domain of SARS-CoV-2 spike protein, preventing viral entry through ACE2 receptors.

In a study published in the New England Journal of Medicine (one of the most prestigious journals in the medical field) data from 275 patients showed a drastic reduction in viral load in patients treated with REGN-COV2. This is clinically significant as hospitalized patients with severe symptoms have higher viral counts than non-hospitalized or asymptomatic patients, suggesting the hypoxaemic, shortness of breath symptoms are related to the viral count and resulting exaggerated immune response.

Based off this result the European Medicines Agency approved the use of REGN-COV2 antibody cocktail in patients who do not require supplemental oxygen but are at high risk of progressing to severe COVID-19.

FDA regulations currently recommend it for patients who are COVID positive with risk factors that may result in their hospitalization but do not recommend it for patients who are already hospitalized, requiring O2 therapy because of COVID or need chronic O2 therapy.

Those that fall into the high-risk categories include patients with a high BMI (over 35), diabetes, on immunosuppressive treatment or with an immunosuppressive disease, over 65 years of age or those with chronic diseases such as renal disease, cardiovascular disease, COPD, or other developmental disorders.

Health Risks of Irregular Eating Habits: How Skipping Meals Affects Your Body

Maintaining a balanced and consistent diet is essential for good health. However, modern lifestyles often lead to irregular eating patterns due to busy schedules, work stress and changing daily routines. Many people skip meals, eat late at night or consume food at inconsistent times.

Understanding the health risks of irregular eating habits is important for maintaining metabolic balance and overall wellbeing. Consistent meal timing plays a key role in supporting digestion, energy levels and long-term health.

 

What Are Irregular Eating Habits?

Irregular eating habits refer to inconsistent or unpredictable meal patterns.

Common examples include:

  • Skipping breakfast or other meals
     

  • Eating meals at varying times each day
     

  • Consuming large meals late at night
     

  • Frequently replacing meals with snacks
     

These habits may disrupt the body’s natural metabolic rhythm.

 

How the Body Regulates Eating Patterns

The human body follows internal biological rhythms that regulate hunger, metabolism and digestion.

When meals occur at consistent times, the digestive system prepares enzymes and hormones needed for efficient food processing.

Irregular eating patterns may interfere with these processes.

 

1. Disruption of Metabolism

Metabolism refers to the process by which the body converts food into energy.

Skipping meals or eating inconsistently may slow metabolic activity, making it harder for the body to regulate energy balance.

This disruption may contribute to metabolic disorders over time.

 

2. Increased Risk of Weight Gain

Although skipping meals may appear to reduce calorie intake, it often leads to overeating later in the day.

Large or late meals may increase calorie consumption and contribute to weight gain.

Irregular eating may also affect hormones that regulate appetite.

 

3. Digestive Problems

The digestive system functions best when meals occur at regular intervals.

Irregular eating may cause symptoms such as:

  • Acid reflux
     

  • Bloating
     

  • Indigestion
     

  • Stomach discomfort
     

Consistent meal timing helps maintain digestive balance.

 

4. Fluctuating Energy Levels

Skipping meals can lead to sudden drops in blood sugar levels.

Low blood sugar may cause symptoms such as:

  • Fatigue
     

  • Dizziness
     

  • Difficulty concentrating
     

Regular meals help maintain steady energy throughout the day.

 

5. Impact on Blood Sugar Control

Irregular eating patterns may disrupt glucose regulation.

Over time, inconsistent meal timing may increase the risk of insulin resistance and type 2 diabetes.

Maintaining stable blood sugar levels is important for metabolic health.

 

6. Nutritional Deficiencies

Skipping meals can reduce the intake of essential nutrients required for body function.

A balanced diet provides vitamins, minerals and other nutrients needed for immunity, metabolism and overall health.

Irregular eating habits may lead to nutritional imbalances.

 

Irregular Eating Habits in the Indian Context

In many urban areas of India, demanding work schedules and long commuting times often lead to irregular meal patterns.

Late-night eating, fast food consumption and skipped meals have become common among professionals and students.

These lifestyle patterns may increase the risk of metabolic and digestive health problems.

Promoting regular meal timing and balanced diets is essential for improving public health.

 

Tips to Maintain Healthy Eating Habits

Establish Regular Meal Times

Eating meals at consistent times each day helps regulate digestion and metabolism.

 

Do Not Skip Breakfast

Breakfast provides essential energy for starting the day and supports metabolic activity.

 

Plan Balanced Meals

Include a variety of foods such as:

  • Whole grains
     

  • Fruits and vegetables
     

  • Lean proteins
     

  • Healthy fats
     

Balanced nutrition supports overall health.

 

Avoid Late-Night Heavy Meals

Eating large meals close to bedtime may disrupt digestion and sleep.

 

Stay Hydrated

Adequate hydration supports digestion and nutrient absorption.

 

When to Seek Medical Advice

Consult a healthcare professional if irregular eating habits lead to:

  • Persistent digestive problems
     

  • Unexplained weight changes
     

  • Chronic fatigue
     

  • Blood sugar irregularities
     

Early intervention can help prevent long-term health complications.

 

Conclusion

Irregular eating habits may significantly impact metabolism, digestion and overall health. Skipping meals, inconsistent meal timing and late-night eating can disrupt the body’s natural rhythms and increase the risk of metabolic disorders.

Maintaining consistent meal schedules, balanced nutrition and healthy lifestyle habits can support digestive health and stable energy levels.

By adopting regular eating routines, individuals can improve metabolic balance and reduce the risk of long-term health complications.

Healthy eating patterns are a fundamental part of maintaining overall wellbeing and long-term health.
