Should You Skip Breakfast? (Maybe.. Here's Why)

Updated: Aug 15

There is an ongoing debate about breakfast; those who believe it is necessary and those who don't. While there may be benefits to eating breakfast, there are also benefits for skipping it.

Here's why you shouldn't feel guilty if you choose not to eat this morning meal.

Reasons You Shouldn't Skip Breakfast

Breakfast eaters are often healthier and slimmer than those who miss breakfast. This may be because breakfast eaters also have other good lifestyle practises.

Eating breakfast may be beneficial for young people who are still growing, as well as athletes and bodybuilders aiming to gain muscle mass or strength.

1) People Who Eat Breakfast Seem to Have Healthier Habits

It's true that breakfast eaters are healthier, according to many studies. They are less likely to be overweight or obese, and they have a reduced chance of developing chronic illnesses. (1, 2, 3)

As a result, many experts believe that eating breakfast is beneficial. These investigations, however, are observational studies, which cannot prove causality.

These studies indicate that individuals who eat breakfast are healthier, but they can't establish that it's because of the meal.

Breakfast eaters are likely to have other healthy lifestyle practises that may account for this. For example, they tend to consume a better diet with more fibre and minerals. (4, 5)

People who miss breakfast, on the other hand, are more likely to smoke, consume more alcohol, and exercise less. (6)

Perhaps these are the reasons why, on average, breakfast eaters are healthier. It's possible that it has nothing to do with the meal itself, but due to other causes.

In reality, high-quality studies, such as randomised controlled trials, indicate that whether you eat or skip breakfast makes little difference to your health.

2) Better for Young People or Those Who Are Growing

Eating breakfast in the morning increases your overall calorie intake for the day, compared with skipping breakfast.

This is better for young people who are still growing and need more calories. For bodybuilders and athletes who require more calories, it is also ideal for them to eat breakfast.

Breakfast also increases your daily protein consumption, which improves your body's capacity to repair and build muscle.

Reasons You Should Skip Breakfast

There are a few reasons that skipping breakfast may be beneficial.

It may have beneficial effects on health, and contrary to popular belief, skipping breakfast may also have benefits for weight loss, and eating breakfast doesn't boost metabolism.

1) Skipping Breakfast May Have Health Benefits

Many intermittent fasting regimens include skipping breakfast. Intermittent fasting has a number of health advantages.

In many intermittent fasting techniques, skipping breakfast is a frequent practise. The 16/8 technique, which entails a 16-hour overnight fast followed by an 8-hour eating window, is one example.

This eating window often runs from noon to evening, so you'll be skipping breakfast every day.

Intermittent fasting has been proven to help people lose weight faster and enhance their metabolic health. (7, 8, 9)

It's worth noting that intermittent fasting and missing breakfast does not have the same effects for everyone. Some people may have favourable benefits, while other people may suffer headaches, blood sugar dips, faintness, inability to concentrate, etc. (10, 11, 12)

2) Eating Breakfast Doesn't Boost Metabolism

The number of calories you burn during the day is unaffected by whether you eat or skip breakfast.

Breakfast is said to "kick-start" the metabolism, but this is not true. These individuals are discussing the thermic impact of food, which is the increase in calories expended after eating.

However, the overall quantity of food eaten during the day is what counts for metabolism. It doesn't matter that much when you eat or how frequently you eat.

People who eat or skip breakfast burn the same amount of calories over 24 hours. (13)

3) Skipping Breakfast Doesn't Cause Weight Gain

Research indicates that whether individuals eat or miss breakfast has no effect. It's true that you eat more at lunch if you skip breakfast, but not enough to make up for the breakfast you missed.

"People who miss breakfast are more likely to gain weight than those who have breakfast." This may seem counterintuitive, since how can not eating lead you to gain weight?

Some people believe that missing breakfast makes you hungry and leads you to overeat later in the day. This seems to make logical sense, yet the science contradicts it.

It's true that missing breakfast makes individuals hungry and leads them to eat more at lunch, but this isn't enough to make up for the breakfast they missed.

In fact, missing breakfast has been found in some studies to decrease total calorie consumption by up to 400 calories per day. (14, 15, 16)

This makes sense since you're essentially eliminating a full meal from your daily diet. The eat or skip breakfast conundrum was recently put to the test in a randomised controlled study.

This was a four-month trial in which 309 overweight/obese men and women were compared to when eating or skipping breakfast. (17)

There was no change in weight between the groups at 4 months. It made no difference whether individuals ate or didn't eat breakfast.

Other research on the impact of breakfast routines on weight back up these findings. Skipping breakfast had no discernible differences. (5, 17, 18)


It is unlikely to make a difference whether you eat or miss breakfast as long as you eat healthily for the rest of the day.

Breakfast does not "kick-start" your metabolism, and missing it will not cause you to overeat and gain weight. This is a misconception based on observational studies that were later debunked in high-quality studies.

Some people prefer to have breakfast, and some people don't. Breakfast is optional and it all comes down to personal taste and your own body.

If you're hungry in the morning and like breakfast, go ahead and eat something nutritious. The ideal breakfast is one that is high in protein.

However, if you are not hungry in the morning and do not believe you need breakfast, skip it.
