In Episode 2 of the Montana Moves and Meals podcast, we discussed my first nutrition tenet: the 80/20 rule of moderation. This principle is meant to allow for some flexibility in one’s diet to include foods that we enjoy but that may not be great for us (the 20%), while maintaining a focus on eating for health (the 80%). By following this tenet, you lose the all-or-nothing approach to nutrition and the excuse that “the diet starts tomorrow!”
After we posted the podcast, I received the following question: “How do you figure what is 20%? 20% of the days? 20% of meals? 20% of calories?” Great question, and one that I felt deserved to be answered for everyone, not just for those who are comment readers.
First, determining the 80% vs 20% is really up to individual discretion. There are no hard and fast rules. But here’s my take: I would say the percentages should be considered in the context of all of the food/beverage choices that you make over the course of a day. If you think about it, we make dozens of eating choices everyday – wheat bread or white? Salad or fries? Trail mix or chips? Milk or water? Opening the refrigerator door or not, etc. So, to follow the 80/20 rule, 80% of those choices are the healthy option; 20% of those choices are based purely on what you want.
I would judge the 80/20 breakdown over a day or even a couple of days as you might have entire meals that are mostly in the 80 or 20 category, but hopefully not entire days that are in the 20%. Determining the 20% doesn’t need to be an exact science; it’s more of just a basic guiding principle and reminder that most of our diet should consist of healthy foods, while still leaving room for foods that make us happy & satisfied. In fact, think broadly when considering this principle. Resist the temptation to categorize each and every food as good or bad, as it’s all too easy to extend this to a judgement about ourselves as good or bad for eating that food. We eat a variety of foods for a variety of reasons, and the food we eat has no bearing on our worth as a person. It does however, have a bearing on our health outcomes and health risks, and that’s why it’s important to prioritize healthy nutritional choices.
Hope this helps.
