Happy New Year, happy eating: my sustainable food resolutions

IRIS Prévention
25 November 2026
This year, my food resolutions don't last until January 15th - they last for life.

The New Year carries with it a universal promise: this time it will be different. This time, I'm going to eat healthy, stop sugar, cook at home every day, lose weight. And on January 15, often, the enthusiasm of the beginning of the year has given way to the reality of everyday life. Not because you lack motivation or willpower, but because most dietary resolutions are poorly designed from the start. In this article - the last in our annual series - I offer you a radically different approach to resolutions: simple, specific, lasting and kind commitments to yourself.

1. Why New Year’s resolutions (almost) always fail

Research in the psychology of behavioral change is clear: around 80% of New Year's resolutions are abandoned before the end of January, according to a study published in the Journal of Clinical Psychology. The reasons are always the same:

  • Too ambitious: I will eat perfectly healthy every day is a resolution doomed to failure. All or nothing is the enemy of lasting change.
  • Too vague: 'eat better' is not actionable. I don't know concretely when, how and what to do differently.
  • Based on deprivation: resolutions that start from 'I stop...' rather than 'I start...' activate a feeling of restriction which depletes motivation.
  • Without a support system: an isolated resolution, without a facilitating context or contingency plan in the event of difficulty, collapses at the first obstacle.
    Resolution specificWhen and howMy plan B if things get stuck
    I eat 5 servings of fruits and vegetables per day1 fruit for breakfast, salad or vegetables for lunch, cooked vegetables for dinnerIf no time: a banana and a fruit yogurt count
    I cook at home at least 4 evenings a year weekI do my batch cooking on Sunday 1 hourEmergency meal: scrambled eggs + salad, sardines + wholemeal bread
    I drink 1.5 L of water per dayA bottle on my desk at work, a glass when I get upHydration reminder app if I forget
    I take my vitamin D every morning from October to AprilCapsule next to my coffee, morning ritualI leave the box clearly visible near the coffee maker
    I eat legumes twice a day weekLentils on Monday, chickpeas on ThursdayPreserved ready to use as a backup if not the time
    I replace refined cereals with completesWhole grain bread, brown rice, oatmealI just start with bread - one change at a time
    I limit sugary drinks to a maximum per weekI always have water with lemon or tea pretThe sparkling water bubble helps me if I run out of soda

2. The sustainable resolutions method: 3 principles

  • Principle 1 - Addition rather than deletion: I don't start by removing foods. I start by adding good things. Add a serving of vegetables, add a handful of nuts, add one legume meal per week. The addition is motivating and does not generate a feeling of deprivation. Removing bad habits naturally follows when good ones take up space.- Principle 2 - Identity rather than behavior: rather than telling myself 'I'm going to try to eat healthier', I tell myself 'I am someone who takes care of their diet'. This form of positive identity is much more persistent than the list of behaviors to adopt. Every good food choice is a confirmation of this identity.
  • Principle 3 - The system rather than will: will is a limited resource that is exhausted. The systems operate automatically. I create systems: I do my meal prep on Sunday, I keep a bowl of fruit visible on the counter, I put the less healthy foods far away and the healthier ones within reach. The environment does the work for me.

3. My 7 food resolutions for the year – concretely

4. What the year taught me about healthy eating

Throughout this series of 52 articles, a common thread has emerged. It's not miracle superfoods, restrictive diets or dietary supplements that make the difference. These are simple principles, repeated regularly and without obsession:

  • Diversity above all: eating variety is more important than eating perfect
  • Whole foods before supplements: a vegetable is always better than a pill
  • Regularity before intensity: 7 balanced meals per week are worth more than a detox Sunday
  • Pleasure is part of prevention: eating healthy without pleasure does not last
  • The health check as a compass: biological markers provide objective information that feeling alone cannot provide

5. My cover letter for the new year

I want to end this series with something different - not a to-do list, but perspective.

Taking care of your diet is not a sacrifice. It is an act of respect for oneself, a form of coherence between what one knows and what one does, a way of taking an active part in one's own health rather than suffering from it.

You don't have to be perfect. You just need to move in the right direction, most of the time, with kindness to yourself when you don't get there. Every meal is a new opportunity - not a test or a punishment.

Health is a long-term investment. What you eat today influences who you are in 10, 20 and 30 years. And that's not a reason to stress - it's a reason to start now, gently, with the first gesture that seems accessible to you.

Happy New Year, happy eating - and above all, good health.

💡 tips to remember

    • 80% of food resolutions fail before the end of January: I rethink them starting from the addition and not the deletion, from the identity and not from the behavior, from the system and not from the will.
    • I choose 3 specific and concretely actionable resolutions rather than 10 general and vague ones. What exactly, when exactly, and what is my plan B?
    • The environment does the work: fruit bowl visible, healthy ingredients accessible, less healthy foods out of sight. I create conditions that facilitate good choices effortlessly.
    • Positive identity lasts longer than the list of behaviors: I am someone who takes care of my diet rather than trying to eat better.
    • Regularity beats intensity: 7 balanced meals per week all year round are worth infinitely more than a perfect January followed by 11 months of abandonment.
    • Pleasure is not the enemy of health - it is the condition. A healthy diet that I enjoy will last. A perfect diet that I am undergoing will collapse.
    • Happy New Year, good plates: each meal is a new opportunity, not an exam. Kindness towards oneself is the first ingredient of good health.
