Is it better to fast or eat 3 meals a day?

When it comes to nourishing our bodies, there are plenty of different theories and opinions out there. One that has been gaining popularity recently is the idea of intermittent fasting. This involves restricting our food intake to certain periods of the day, or even going entire days without eating at all. But is this really a better approach than the traditional three-meals-a-day routine? Let’s take a closer look at the pros and cons of both methods.

What Happens to Your Body When Fasting?

First, it’s important to understand what happens to your body during fasting. When you fast, your body enters a state of ketosis. Ketosis is a metabolic state in which the body starts burning stored fat for fuel instead of carbohydrates. During this time, your insulin levels drop, and your body produces more growth hormone and adrenaline.


Ketosis can have several benefits for the body. It can help with weight loss, lower inflammation, improve blood sugar control, and reduce the risk of several diseases. However, fasting is not suitable for everyone, especially those who have diabetes or are pregnant or breastfeeding.

The Pros and Cons of Eating Three Meals a Day

Eating three meals a day is the traditional way of consuming food. It has been a norm in our society for ages. This eating habit gives the body a steady supply of energy throughout the day. However, it may not work for everyone. Here’s a look at the pros and cons of consuming three meals a day.


Some of the benefits of consuming three meals a day include:

  • Stable blood sugar levels: Eating three meals at regular intervals can help maintain stable blood sugar levels, which is essential for regulating energy levels and preventing major health issues such as diabetes.
  • Efficient digestion: Eating small portions regularly helps easy digestion of food. As the stomach has to break down a small amount of food frequently, it reduces the workload on the digestive system and ensures maximum nutrient absorption.
  • Easy to plan: Eating breakfast, lunch, and dinner has become a societal norm. Planning and preparing meals can be done with ease, and you will not have to worry about making any significant changes to your routine.


However, there are some downsides to consuming three meals a day:

  • Overeating: Sometimes, people tend to have large meals, which can lead to overeating. This can cause weight gain and other health problems such as indigestion and heartburns.
  • Unhealthy food choices: When people have three meals a day, they tend to snack in between, and most of the time, it’s unhealthy food options such as crisps or chocolates.
  • Hunger pangs: As the gap between meals is extended, it can make you feel hungry, which can result in binge eating.

Intermittent Fasting

Intermittent fasting is a popular eating pattern that involves regular fasting periods. It’s not about restricting calorie intake, but instead, controlling the hours of eating. Intermittent fasting allows you to consume the same amount of food as you would in three meals, but in two meals or sometimes in just one. Here’s a look at the pros and cons of intermittent fasting.


Intermittent fasting has several benefits, including:

  • Weight loss: Intermittent fasting helps burn fat that is stored in the body. This can help with weight loss.
  • Controlled blood sugar levels: Intermittent fasting can help regulate blood sugar levels, which helps prevent diabetes and obesity.
  • Improved brain function: Intermittent fasting can improve cognitive abilities, leading to better concentration, memory, and mental clarity.


However, intermittent fasting also has some downsides, such as:

  • Difficult to adapt: Intermittent fasting can be challenging to adjust to, especially for people who are used to consuming three meals a day.
  • Increased hunger: Extended fasting can lead to increased hunger pangs, which can be hard to manage.
  • Not suitable for everyone: Intermittent fasting may not be appropriate for pregnant or breastfeeding women or those with certain medical conditions.


Both fasting and eating three meals a day have their advantages and disadvantages. The best approach varies from person to person, depending on their preferences, lifestyle, and medical conditions. However, it is essential to maintain a healthy and balanced diet regardless of the approach taken.

Healthy Balanced Diet

10 Benefits of Fasting

Fasting has been practised for centuries, with numerous health benefits attributed to it. Here are some of the benefits associated with fasting:

1. Weight Loss

Fasting can help you shed those extra pounds quickly. Since you are not consuming any calories, your body starts using stored fat for energy. This way, you end up burning more calories than you consume, leading to weight loss.

2. Improved Insulin Sensitivity

Intermittent fasting has been shown to improve insulin sensitivity, leading to better blood sugar control in people with type 2 diabetes. Fasting also reduces insulin resistance, which can lower fasting insulin levels and reduce the risk of developing type 2 diabetes.

3. Reduced Inflammation

Fasting has been shown to reduce inflammation, which is the root cause of many chronic diseases like cancer, heart disease, and arthritis. Fasting can also improve gut health by reducing inflammation in the gut and promoting the growth of healthy gut bacteria.

4. Improved Heart Health

Fasting can help lower blood pressure, triglycerides, and cholesterol levels, which are all risk factors for heart disease. Intermittent fasting has also been shown to reduce heart rate and improve heart rate variability, which are both markers of good heart health.

5. Improved Brain Function

Fasting has been shown to improve cognitive function, including memory, focus, and concentration. Fasting also stimulates the growth of new nerve cells in the brain, which can improve brain health and protect against neurodegenerative diseases.

6. Increased Lifespan

Fasting has been shown to extend lifespan in animals, and some studies suggest that it may have the same effect in humans. Fasting can reduce oxidative stress, which is a major contributor to ageing, and promote the growth of healthy cells and tissues.

7. Improved Immune System

Fasting can boost your immune system by increasing the production of white blood cells which help fight infection and disease. Fasting can also reduce the risk of autoimmune diseases like lupus, psoriasis, and rheumatoid arthritis.

8. Reduced Risk of Cancer

Fasting has been shown to reduce the risk of certain cancers like breast, colon, and prostate cancer. Fasting can help reduce inflammation and oxidative stress, which can promote the growth of cancer cells.

9. Improved Sleep Quality

Fasting can help you sleep better by regulating your circadian rhythm. Fasting also increases the production of melatonin, a hormone that regulates sleep.

10. Increased Energy Levels

Fasting can boost your energy levels by improving metabolism and increasing the production of human growth hormone. Fasting can also improve mental clarity and focus, making you more productive and efficient throughout the day.

Benefits of Eating 3 Meals a Day

While fasting has its advantages, it might not be everyone’s favorite method, and some may find it difficult to maintain. Individuals may prefer to follow a consistent eating pattern throughout the day. In this section, we’ll explore the benefits of eating three meals a day.

1. A steady supply of energy

When you eat three meals every day, you’ll have a steady supply of energy throughout the day. Your body derives glucose or energy from the food you eat, which helps to fuel the body’s everyday activities. If you eat only one or two large meals a day, you can feel sluggish and lose focus after the meal, making it difficult to get work done.

Consistent Eating Pattern Benefits

2. Improved metabolism

When you gradually increase your food intake throughout the day, your metabolism becomes more efficient. The more frequently you consume small meals, the more efficiently your metabolism works. It’s like fueling up your car. If you fill it up once a month, the oil inside the motor is likely to solidify, diminishing its efficiency. Similarly, when you eat three meals a day, your metabolism’s efficiency increases, and it may be easier for you to lose weight or maintain a healthy weight.

3. Helps with portion control

When you follow a consistent eating pattern, you’re more likely to maintain portion control. You have a better idea of what, when, and how much you’re consuming. You’re less likely to overindulge in unhealthy snacks or meals when you eat small, but better portions at each meal.

Portion Control

4. Better digestion

If you eat regularly throughout the day, your body produces digestive enzymes on a regular basis. This helps your gut digest food more efficiently, relieving you of bloating and other gastrointestinal problems.

5. Higher nutrient density

Another benefit to eating three meals a day is that you consume a more diversified and nutrient-dense diet than you would if you were fasting. With more options, you can select from a range of healthy foods that provide a variety of essential vitamins, minerals, and other essential nutrients.

Steady supply of energy
Improved metabolism
Helps with portion control
Better digestion
Higher nutrient density

Both fasting and eating three meals a day have their advantages and disadvantages. Ultimately, the best approach to eating is one that works for you, your body, and your lifestyle. The main takeaway is that regardless of how frequently you eat, you need to make sure you’re consuming healthy and nutritious foods.
