Have you ever decided to adopt a new behavior – how to drink more water, exercise every day or eat more vegetables – thinking they would take 21 days to form a habit?
If so, welcome to the club!
Before studying the science of behavioral change as a registered dietitian, I also wondered how long the habits should climb. I believed that common myths as “21-day rule”, which claims that three weeks is all it takes to form a new habit.
learning How habits actually work have transformed my life and the advice I share with clients.
In this article, I would break down the real timeline for construction habits and share practical tips to help you create sustainable behavior.
By the end, you will know what makes the habits really climb and how you can start building healthier ones today.
“21 days to form a habit“ Myth – Where did it come?
You may have heard the idea that it takes only 21 days to form a habit. This belief is widespread. It is a key element of self-help books and motivational speeches. Where did it come from?
The origin of the 21-day myth
The myth seems to be originally from a book entitled “Psycho-Cybernetics” by Dr. Maxwell Maltz, a plastic surgeon and author from the 1960s. Maltz noticed that patients took about 21 days to adapt to changes in their self-image (1).
This observation extended to the formation of the habit, leading to the appearance of the myth of the 21-day habit. Been popular by the “experts” of self-help since then!
Why did it stuck
The idea is likely to become known because it is a secure. Who would not want to believe that they can fully acquire new behavior for a short period?
Unfortunately, this over time is not supported by scientific evidence and rarely holds in real life.
What does science say
Construction habits generally begin with making a decision and creating a plan, followed by its continuous practice. With sufficient repetition and pleasure, eventually becomes the second nature.
Science says that the time needed to form a habit is completely individual, but it is not completely accidental.
Let us consider how long it really takes to build a habit and the factors that influence the formation of the habit.
It takes more than 21 days to form a habit – here it is how long
While the actual timeline of forming the habit varies greatly, the last science offers data to help you succeed.
What does the actual research indicate
- A 2009 study published in European Social Psychology Magazine proposed to take on average 66 days to fully adopt a new behavior (2).
- New research from the University of South Australia suggests that new habits can get two to five months (On average 106-154 days) or even up to 335 days to make them automatic (3).
What does this mean to you
The myth of forming the usual ordinary 21-day ordinary custom sets unrealistic expectations for most people trying to build new habits.
Realizing that it should AGE To make stick habits can help set realistic expectations and promote long -term success (3).
So, instead of feeling discouraged after 21 days, admit that the process often lasts several months – and that’s perfectly normal!

What makes a habit of climbing?
Building long -term habits requires more than just a will.
Recent research highlights some factors that may affect if new behaviors become permanent (3):
- frequent: The more often you do, the stronger the habit.
- AGE: Breakfast habits tend to stick better than evening habits.
- The type of habit: Some habits are easier to decide than others. Flossing your teeth, for example, is much easier for most people to adopt than running 5 miles a day.
- Personal choice: Making habits you actually want to make makes a big difference.
- pleasure: When an activity brings joy, it is of course easier to repeat and strengthen as a habit.
- Planning •: Being specific to when, where, and exactly what you will do helps to block it.
- Preparation routines: Small preparatory actions, such as determining training clothes the night before, can create momentum for greater habits.
At the top of these, there are even more principles supported by the research to consider when choosing a habit and ensuring to climb.
Let them dive deeper on how to make your last habits last.
Suggestion and routine
The habits climb when they are associated with stable signs.
When repeating a behavior in the same context over time, those signs help promote automatic responses, making it easier to stay on the right track in the future (3).
But instead of trying to go out with new signs for each habit, try to connect them to the existing parts of your routine.
For example, you want to drink more water? Drink a glass whenever you have a meal or snack.
Positive reinforcement
Celebrating small victories strengthens your commitment and strengthens habits by making them more useful.
When clients report by making healthier choices, I encourage them to celebrate in significant ways. This can be sharing victory with a friend or even writing success to reflect later.
It can also be useful to set a long -term goal and reward yourself when you reach it (Hello, Massage!).
This approach exploits the natural response of brain dopamine to keep you motivated, making the habit more enjoyable and consistent over time (4).
IDENTITY
Framing habits as part of your identity makes them more predisposed to stick.
In fact, research suggests that when habits match your personal values and how you see yourself, behavioral change efforts can be much more successful (5).
By connecting habits with your sense of identity, you are not just doing a task, you are strengthening who you want to be. This can lead to higher self -esteem and a push towards making your ideal self (5).
So, for example, Instead of thinking, “I am trying to work more”, I remember myself, “I am an active person who gives priority to training.”
Similarly, instead of, “I’m planning to eat more fruit”, you might say, “I’m someone who appreciates my health and chooses nutrients.”
These and other statements can help strengthen your identity as someone who is committed to their health and health, making it easier to adhere to healthy habits in the long run.
LIABILITY
You’ve probably heard the phrase, “what is measured, managed.” This is especially true in the formation of habit.
Responsibility is a game change, and self-monitoring can play a crucial role in staying on the right track (3).
By following your habits, you can stay focused, celebrate small victories and build momentum towards long -term success.
Thanks to technology, self-monitoring has never been easier. For example, applications like Myfitnesspal and Wearables offer many tools to keep you responsible. But, you can also use a notebook for tracking the habit or another method of self-monitoring that works for you.
SUPPORTING
In addition to self-monitoring, Having continuous support on your health journey can improve your chances of climbing healthy habits (3).
This support can come from a certified health coach, personal trainer, registered dietician, mental health professional, or even an online community.
Or you can find a responsibility partner in a friend or family member who shares similar goals and encourages you along the way.

It is unlikely – most habits need weeks or months to form. However, small lasting actions can lay the foundation.
What is the best way to make a habit of climbing?
While many factors are involved, consistency and frequency are essential. Repetition in the same context (environment or situation) strengthens nerve pathways (3).
How can I stay motivated when building a new habit?
Start with small, specific, accessible and pleasant habits that match your greatest goals. Connect these habits with your identity, set responsibilities, celebrate small victories and seek support from others.
Is it harder to say bad habits than to build new?
Yes, in most cases. Breaking bad habits requires actively stopping automatic behaviors, while new formation involves learning and repetitioning new models (6). Replacing the habit, which directly replaces old habits with new ones, can sometimes make both processes easier (7).
