Is it healthy to not eat after 3pm?

Many people wonder if it’s healthy to avoid eating after 3pm. Some believe that skipping dinner can lead to weight loss and improve overall health, while others argue that it can disrupt the body’s natural digestion process and cause negative effects. In this article, we’ll explore the pros and cons of not eating after 3pm and provide some insight to help you make an informed decision about whether or not to try this approach.

What Happens to Your Body When You Don’t Eat After 3pm?

Intermittent fasting, also known as time-restricted eating, is a popular trend in the health and fitness world, and one version of it is eating all your meals within an eight-hour window then fasting for the remaining 16. Some people even recommend this approach but with a shorter window, not eating anything after 3pm. While there is some scientific basis for the approach, there are also some downsides that you should know before you decide whether it is right for you.

1. You May Sleep Better

Benefits of eating in a certain window

Intermittent fasting can help you sleep better. When you don’t eat after 3pm and then go to bed, you’re far less likely to feel bloated, gassy, or uncomfortable, which can impact your quality of sleep. Moreover, your digestive system can rest instead of working during the night.

2. You Might See Some Weight Loss

Benefits of not eating after 3pm

Not eating anything after 3pm can result in weight loss. The idea behind it is simple: by not eating after 3pm, you are consuming fewer calories, which can result in weight loss if you stick with it over time. However, this doesn’t mean you should skip meals.

3. Your Blood Sugar Levels May Be More Stable

Stable blood sugar levels

Eating late at night can cause blood sugar spikes and dips, which are hard on your body. When you don’t eat after 3pm, however, your blood sugar levels may be more stable. With stable blood sugar levels, you’re less likely to experience mood swings and fatigue. Stable blood sugar levels also benefit your mental health and cognitive function.

4. You Could Experience Low Energy Levels

One of the most common side effects of not eating after 3pm is low energy levels. Carbohydrates from food are the body’s primary source of energy, and when you don’t eat, your body is forced to rely on fat reserves for energy, which can make you feel tired and sluggish.

5. You Could Overeat at Other Times


If you don’t eat anything after 3pm, you might feel excessively hungry, and you may overeat at other times. Overeating leads to weight gain, and it can be hard to make up for the extra calories you consume by skipping dinner. A more effective weight loss method would be to eat healthy foods in the right quantity, rather than skipping meals.

6. You Will Be More Focused


When you’re not digesting food, your body and mind can concentrate on other tasks more easily. This may be particularly beneficial if you have a lot of work to do or need to study for an exam.

7. You May Be More Prone to Cravings

Food cravings

If you’re used to snacking or eating late at night, not eating anything after 3pm can lead to food cravings in the evening. So, you may find yourself snacking or having cravings for sweets, which can be a difficult habit to break over time.

8. It Might Not Work for Everyone

Not for everyone

Not everybody responds to time-restricted eating the same way. Some people might find that it works very well for them, while others might experience increased fatigue, irritability, or mood swings.

9. It Can Be Hard to Stick With

Difficult to stick to

One of the most significant challenges of not eating after 3pm is sticking with it. Eating schedules vary from person to person, so some people might find it challenging to switch to a new way of eating.

10. Talk to Your Doctor Before Making Any Changes to Your Diet

Doctor's advice

Before making any changes to your diet, you should always consult a healthcare professional. This is particularly important if you have a history of chronic conditions, such as diabetes, high blood pressure, or heart disease, or if you are pregnant, breastfeeding, or planning to be.

In conclusion, not eating after 3pm has some potential upsides, including better sleep, more stable blood sugar levels, and weight loss. However, it can also lead to low energy levels, food cravings, and difficulty sticking with the approach in the long term.

What Happens to Your Body When You Avoid Eating After 3pm?

body metabolism Most people believe that not eating after 3pm is the best way to lose weight, but is it truly healthy? It is necessary to understand what your body goes through when you eliminate an entire meal from your day.

1. Low Energy and Tiredness

low energy The food you eat supplies the necessary energy for your body to function, and skipping meals can often leave you feeling sluggish and tired. When you don’t eat for an extended period, your body burns glucose for energy and relies on fat reserves to meet your energy needs.

2. Slowed Metabolism

slow metabolism Your metabolism slows down when you don’t consume enough calories. Your body interprets the lack of food as a sign of threat and decreases its functioning to preserve energy. In turn, weight loss becomes considerably more challenging because your body is burning fewer calories.

3. Overeating and Cravings

overeating and cravings Not eating enough during the day may result in hunger pangs at night, which might cause you to overeat or crave unhealthy foods. When your body goes without food for an extended period, your blood sugar drops, causing uncontrollable hunger and cravings.

4. Negative Impact on Digestion

negative impacts on digestion Your digestive system requires continuous nourishment to function properly. Fasting for long periods can cause digestive issues such as constipation, bloating, or other gastrointestinal problems.

5. Disrupts Hormonal Balance

disrupts hormonal balance Skipping meals can disrupt your hormonal balance, which can cause a wide range of issues such as a decrease in thyroid function, an increase in cortisol levels, or an imbalance of insulin levels.

6. Loss of Lean Muscle

loss of lean muscle Not consuming enough calories throughout the day forces your body to consume the stored energy, which comes from your lean muscle mass. This causes you to lose muscle mass, decreasing your metabolism and making it more difficult to lose weight.

7. Irritability and Mood Swings

irritability and mood swings When your body goes without food, it can cause irritability, mood swings, and other mood-related issues. This is because low blood sugar levels cause your mood to fluctuate, and your mood is heavily influenced by your diet.

8. Dehydration

dehydration importance Fasting can cause dehydration because your body needs water to break down stored energy. Lack of water can also cause several health issues, including headaches and fatigue. It is crucial to drink enough water throughout the day to prevent dehydration.

9. Poor Sleep Quality

poor sleep quality Fasting, especially before bedtime, can cause restless sleep or poor sleep quality. Your body relies on the food you eat to produce the necessary hormones for good sleep quality, including melatonin and serotonin.

10. Nutrient Deficiencies

nutrient deficiencies Fasting can prevent you from receiving the necessary nutrients that your body requires. Skipping meals, particularly breakfast, causes a deficiency in your body’s essential nutrients, including vitamins, minerals, and micronutrients.

It is critical to note that every individual’s body responds differently, and what works for one person may not work for another. Consult with a nutritionist or a medical professional before making any significant dietary changes.

How Can Not Eating After 3pm Affect Your Health?

The Impact on Your Metabolism

The metabolism is responsible for converting food into energy and nutrients that our body needs to function properly. When you eat a meal, your metabolism works to break down the food and absorb the nutrients. However, if you stop eating after 3 pm, your metabolism slows down because it has less work to do. This can make it harder to lose weight and maintain a healthy weight.

A study conducted by the American Journal of Clinical Nutrition found that skipping meals, particularly dinner, can cause metabolic disturbances, including insulin resistance and glucose intolerance, which can lead to type 2 diabetes and obesity.

The Effects on Your Sleeping Habits

Not eating after 3 pm can also affect your sleeping habits. When you skip dinner, you may go to bed feeling hungry, and this can cause insomnia. According to sleep experts, eating small, healthy meals throughout the day can help improve sleep quality as it ensures that your body has enough energy to function properly without feeling hungry.

Moreover, according to a study published in the Journal of Clinical Sleep Medicine, eating late at night, especially skipping dinner, can hinder the production of growth hormone, which is responsible for regenerating tissues and cells, and repairs muscle tissues. This hormone is essential for restful sleep, and not having it can lead to disrupted sleep patterns.

Effects of not Eating After 3pm

The Impact on Your Blood Sugar Levels

Not eating after 3 pm can cause your blood sugar levels to dip too low. This can be dangerous for people with diabetes, as it can cause a hypoglycemic episode that can be life-threatening. When you skip a meal, your body has less energy to function, and this can cause it to tap into its sugar reserves, thereby causing a dip in blood sugar levels.

Effects of not Eating After 3pm

The Effect on Your Mental Health

Your eating habits can affect your mental health. A study published in the American Journal of Clinical Nutrition shows that people who eat only one or two meals a day are at a higher risk of developing depression than those who eat three meals a day. Similarly, eating late at night, especially after 8 pm, can negatively impact your mood and cause anxiety.

Moreover, when you skip dinner, you may feel irritable, moody, and tired. This is because your body is not getting the nutrients it needs to function properly. Furthermore, according to a report published in the British Journal of Nutrition, low-carb diets, which often omit dinner, have been linked to a higher incidence of depression, confusion, and anxiety.

Effects of not Eating After 3pm


In conclusion, not eating after 3 pm can have several impacts on your health. It can affect your metabolism, sleeping habits, blood sugar levels, and mental health. Therefore, it’s essential to develop a healthy eating pattern to maintain a healthy lifestyle.
