How to Eat What You Want in Balance (The 80/20 Rule)

Achieving balance in your diet can sometimes feel impossible, especially when life is busy, and cravings strike. That’s where the 80/20 rule comes in, a simple, flexible approach to eating that encourages moderation and sustainable habits. In this blog, we’ll explore how you can enjoy your favourite foods guilt-free while making healthful choices most of the time, all through the lens of the Pareto Principle.

What Is the 80/20 Rule?

The 80/20 rule is a straightforward guideline for balanced eating: 80% of the time, focus on nutrient-dense, whole foods like vegetables, lean proteins, fruits, and whole grains. For the remaining 20%, allow yourself the flexibility to enjoy indulgences like a dessert, takeaway, or a glass of wine.

The principle behind the rule is rooted in the Pareto Principle, which suggests that 80% of results come from 20% of actions. This concept, widely applied in business and productivity, also works brilliantly for nutrition by showing that small, consistent efforts can have a big impact. We're looking at flipping it around in this instance or usage of the concept! 20% of the time doing the ‘negative impact’ actions

Why It Works

Sustainability: Unlike restrictive diets, the 80/20 rule doesn’t cut out your favourite treats, making it easier to stick with long-term.
Flexibility: It allows room for life’s special moments, like birthday cake or a festive meal without guilt.
Focus on Progress, Not Perfection: This approach promotes mindful eating and avoids the all-or-nothing mindset, which can lead to burnout or bingeing.

The Science Behind Balanced Eating

Studies consistently show that extreme dieting or excessive restriction often leads to failure. For instance:

A study from the National Institute of Health found that restrictive diets often lead to "yo-yo dieting," where weight is lost and regained, creating long-term health risks【1】.
Allowing small indulgences has been linked to improved adherence to healthy eating plans over time【2】.

Practical Steps to Implement the 80/20 Rule

1. Plan Your Meals

Dedicate time to planning meals for the week to ensure you have a variety of nutrient-dense options ready.
Use apps or meal planners to allocate your “80” and “20” meal choices.

2. Mind Your Portions

For your “20%” indulgences, enjoy smaller portions. For example, have one scoop of ice cream instead of three or opt for a smaller slice of cake.

3. Balance Within a Day

If you have a treat in the morning (like a croissant), make your other meals that day packed with lean proteins, healthy fats, and veggies. Though I recommend desserts and sweet treats only be at the end of your day or meal where possible and not how you start your day!

4. Batch Cook

Prepare meals ahead of time to prevent reaching for processed or unhealthy options when you’re in a rush or choose easy to make meals in your meal planning!

Examples of Healthful Choices for Your 80%

Breakfast: Overnight oats with almond milk, chia seeds, and fresh berries.
Lunch: Grilled chicken salad with mixed greens, avocado, and a homemade vinaigrette.
Dinner: Baked salmon with quinoa and roasted vegetables.
Snacks: A handful of nuts or sliced veggies with home made hummus.

Flexibility for the 20%

The “20” in the nutrition 80/20 rule allows you to enjoy foods you love without guilt. Examples include:

A small bowl of crisps during a movie night.
A takeaway meal once a week.
Dessert on special occasions.
Eating or drinking out once a week.
Friday treats for children after school.

By enjoying these foods more mindfully, you maintain a positive relationship with food while staying aligned with your health goals. I have gone from being addicted to 4-6 Nespresso per day and lots of diet Coke to thoroughly enjoying one incredible decaf macchiato from my local coffee shop per week, occasionally I will have a second one in a week if my husband is off work and wants to head into town together. Before, it was a bad habit and addiction that I thought I ‘loved’, but it didn’t love my body, and I was constantly sick. Before, I was going through the motions, but now I truly enjoy that special coffee.

Striking the Right Balance Between Indulgence and Health

Finding balance is key to the 80/20 rule’s success. Here’s how to maintain flexibility while prioritising health:

Practice Mindfulness: Pay attention to what you’re eating and savour every bite of your indulgences. If you have my book Switches, Ditches and Additions- A simplified guide to lower-tox living then you have the free download resources with the Food Diary you can reprint and use as needed.
Focus on Quality Over Quantity: Choose high-quality indulgences like artisanal chocolate instead of highly processed options. My favourite is high-quality dark chocolate- which, if done right, you guys are naturally vegan! Milk should not be in Dark Chocolate!
Avoid Labelling Food: Instead of thinking of foods as “good” or “bad,” consider how they fit into your overall plan. In our home, I chatted with the children, and we have decided to call the not-so-healthful foods we enjoy on occasion ‘cheats’ instead of ‘treats’. We decided to do this because the word treat suggests something positive and the things we now enjoy as cheats are certainly not healthful, so a cheat is what we agreed on, and we’re all allowed our favourite cheats in moderation.

Why 20% Is Enough

The Pareto Principle suggests that 80% of outcomes are driven by 20% of causes. This can be applied to health by recognising that small, intentional choices in 80% of your meals lead to significant benefits. 20% of the not-so-healthful choices can produce 80% of the negative side effects we experience, so why make ourselves do that?

Eating nutrient-dense foods 80% of the time provides your body with the vitamins and minerals it needs to thrive【3】.
Enjoying flexibility 20% of the time helps reduce the psychological stress associated with dieting and improves adherence【4】.

Tips for Staying Consistent

Be Prepared: Always have healthy snacks like nuts or fruit on hand to avoid grabbing less nutritious options when you’re hungry.
Stay Hydrated: Dehydration can sometimes feel like hunger, leading to unnecessary snacking. Aim for 8-10 glasses of water daily. I also keep EneryFizz in my pockets and bags; my car generally has a box stuffed somewhere!
Track Your Progress: Keep a food journal to monitor your 80/20 split and reflect on how it makes you feel.
Celebrate Small Wins: Acknowledge your efforts and focus on long-term progress rather than short-term perfection.

In Conclusion: Balance Is the Key to Freedom

The 80/20 rule is not just a way to eat, it’s a lifestyle. It teaches us to enjoy our food without guilt while making choices that support our health. By adopting this mindset, you’ll find yourself free from the pressures of perfection and ready to enjoy a sustainable, nourishing relationship with food.

If you’re ready to embrace balance in your eating habits, plan a week of meals that align with the 80/20 rule. Remember, it’s not about restriction- it’s about freedom.
