Why am I writing about habits on a nutrition blog?

In March I started to write a series of articles about habits:

As I was about to publish a fourth article, I realised I had never fully explained why habits are important when it comes to nutrition.

Habits play a crucial role in nutrition because they are the foundation upon which our dietary and lifestyle choices are built. Forming healthy habits is essential for long-term well-being as it influences our ability to maintain a balanced diet and an active lifestyle.

When we establish positive dietary routines, such as eating regular, nutrient-rich meals and snacks, staying hydrated, and incorporating a variety of fruits, vegetables, lean proteins, and whole grains into our diets, simultaneously engaging in regular physical exercise, these habits become second nature. Over time, they reduce the reliance on willpower and make it easier to make consistently nutritious choices and to stay physically active.

On the other hand, lack of movement and unhealthy eating habits, like excessive consumption of sugary snacks or processed foods, can lead to excessive weight, chronic health issues, and nutritional deficiencies. Therefore, cultivating good eating and lifestyle habits is fundamental to achieving and sustaining a healthy life, as they help us make better choices effortlessly and ensure that our nutritional needs are met over the long term.

As always in nutrition (as in life!), perfection is not the goal, small and consistent efforts are the key to lasting change.

Building habits (part 2): key steps

In the first article I explained how habits support the executive functions of the brain. It is estimated that 40% of our actions rely on habits, this is why building habits that serve your goals is essential. Here are a few tips for that.

Tip 1: Identify the habit

The new habit or routine is the behaviour you want to start or change. This can be exercising, stop adding salt, walking more. I will take the example of my Saturday 8.30am yoga class.

Tip 2: Set reminders

One of the key aspects to forming a new habit is remembering everything you need to remember in order to follow through on your aspiration. Forgetting is easy, as our brains always take the easy way, the way of current habits 😉

In my case, I have 2 reminders for this yoga class: one to remember to book the class, and one popping on my phone 30mins before the class.

Tip 3: Start small

This means being specific, and to think of the when, where, how. My aim was not to go to yoga everyday, but to commit to this one, every Saturday. If you can’t proceed to your chosen habit (class cancelled, preferred food not available etc) , have an alternative so that your brain does not associate the reminder to nothing. My alternative to yoga is running. Anything is better than nothing.

Small actions are the seeds for the habit to grow, they activate your neuronal networks.

Tip 4: Reward yourself

We are wired to seek pleasure. Our brain releases « happiness » chemicals during reward, which help the remodelling of neuronal circuits and new habits to stick. We usually think of extrinsic rewards (money, food, objects) but intrinsic rewards work just as well: this feeling once you finish your run, the calm after yoga, learning a new skill, being more energised etc. Remember that the reward comes from the smallest action towards your goal, so the smallest step towards changing or building a habit is rewarding.

After my yoga class, I feel both relaxed and energised, I am (usually!) satisfied with the progress made, and seeing my teacher is a pleasure in itself.

Tip 5: Repetition

As you repeat an action, the new neuronal circuits reinforce and it starts to require less effort. With time, the action is transferred from executive brain, that requires a lot of mental energy, to the autopilot brain and it becomes easier and almost automatic.

And you, what habit would you like to build to achieve your goals?

My current challenge is to eat less salted butter to decrease my overall salt consumption 🙂

Building habits (part 1) : why habits matter

Today’s post will be the first of a series about habits (and change). The objective is to give you an explanation of why we have habits, and how we can change them to make them literally work for us. Why do I write about habits here? Because a lot of our lifestyle choices (diet, exercise, alcohol consumption, smoking…) consist in habits, and if we want to make a lifestyle change last, having some basic knowledge in psychology and neuroscience can help. Let’s start by having a look at our brain.

As human we have a uniquely large executive brain that support executive functions such as working memory, flexible thinking, impulse control, self monitoring, motivation, emotional control, willpower, planning, prioritisation and task management. These functions are future-oriented and enable us to make decisions according to our objectives.

Executive functions require a lot of mental energy, which can be drained by the demands of our busy, modern lives, leaving us feeling low.

This is where the autopilot, that sits deep within our brain, comes handy. The autopilot does not interact with motivation, it is made of habits. Habits are stimulus-response behavioural task, they are automatic. Brushing your teeth, going to the gym every Monday lunchtime, eating porridge at breakfast, adding salt to your food….

If our habits support our goals, we rely on autopilot more and have more mental energy available for our executive brain. We are more motivated, we perform better. When our habits don’t align with our objectives, our executive brain uses extra mental energy to suppress them, eventually we risk feel drained. The problem is that we cannot always replenish our mental energy enough, or reduce the demands of our executive brain.

Therefore, to cope with the demands of our busy lives, we can build habits that support our goals, while changing the habits that go in their way.
