The 80/20 rule is based on the Pareto Principle, which allows for a balanced and flexible approach to eating. The Pareto Principle suggests that 80% of your results come from 20% of your effort.
When you apply this rule to your diet, it means that if you focus on eating nutritious whole foods such as fruits, veggies, whole grains, lean protein options, and healthy fats 80% of the time, you can spend the remaining 20% on less healthy options, including your favorite treats, without feeling guilty.
The 80/20 approach to diet provides a more sustainable eating pattern as opposed to a strict diet, making it easier to maintain over the long term.
