You’ve probably heard that you should eat five meals a day, either because it helps you lose weight, because it speeds up your metabolism, or because you have to eat every three hours so you don’t feel hungry.

But is this true?

We’ll answer this interesting question in this article.

How many meals do you have to eat a day?

The fact that you have to eat five meals a day isn’t completely true, as this depends on each person and their hunger, routine, work, schedules, and physical activity, among other factors.

If you force yourself to eat a mid-morning and mid-afternoon snack, this can translate into eating foods that you shouldn’t, such as sweets, juices, soft drinks, chips, sausages, sweetened milk products… Many times, people choose these snack foods instead of healthier choices. Therefore, meal quality is more important than quantity. It’s better to eat three healthy meals a day than five unhealthy foods.

So what meals are the most important? Is skipping breakfast bad? No meals are more important than others. Also, it doesn’t matter if you don’t eat breakfast because you aren’t hungry or if you eat breakfast at noon instead of at seven in the morning.

Does eating five times a day speed up metabolism?

This idea comes from the fact that, when you eat, you expend energy to digest and break down foods in all their components. This is what’s called the thermic effect of food.

However, it turns out that the calories you use for digestion are more or less proportional to the volume of food you eat and the type of macronutrients. This means that if you follow a 2,000 kcal a day diet, it doesn’t matter if you eat three or five meals, as the thermic effect will be the same.

The Journal of Nutrition published a study in which the authors concluded that there’s no solid scientific evidence to say that increasing meal frequency can aid weight loss.

What if you fast?

It’s important to eat when you’re hungry. This is because you have a hunger and satiety mechanism that’s controlled by the hormones ghrelin and leptin. It’s also important to make sure children eat.

Healthy adults, without special circumstances, such as athletes or pregnant women, can go many hours without eating, even an entire day. If you fast for several hours and the glucose present in the blood is consumed, the body uses liver and muscle glycogen. Once these reserves run out, the body activates gluconeogenesis: glucose production from proteolysis and lipolysis (destruction of muscle and adipose tissue), which generates ketone bodies that are expelled in urine.

In fact, intermittent fasting may be a good weight loss resource for some people. This fasting consists of 16 hours without eating, which pretty much means skipping breakfast. However, it’s advisable to do so under professional supervision.

When is it appropriate to eat five meals a day?

  • To control anxiety and hunger. If you eat five meals a day, you’re more likely to be less hungry and better control meal quantities. However, if you skip a meal, you might feel very hungry and binge, meaning you’ll eat more food than you should.
  • If you suffer from certain diseases, such as diabetes, to prevent hypoglycemia and maintain constant blood glucose levels.
  • If you’re an athlete who has to eat large amounts of food. It’s easier to do it in five meals than three and it makes it easier to control the optimal timing of food intake.


It’s preferable to create a mealtime routine. If you’re used to eating five times a day, it’ll be hard for you to eat three meals, and vice versa. Therefore, each case is different.

The most important thing is to eat healthy and satiating foods. If you eat healthy foods, the number of meals you eat a day won’t matter as much.
