The table shows the six degrees of clean eating. Take a look at what each degree entails, and think about which one best fits your life.
| Degree | What You Eat When Following This Degree |
| 20% | At the beginning of your eating clean adventure — or if you're trying to wean kids (or a reluctant spouse) off of a junk food diet — start by changing one meal in a five-day week into a clean meal. |
| 40% | Add another clean meal a week to your plan to continue the eating clean journey. You can also start at this level. |
| 50% | If you want to live an eating clean lifestyle, 50% is really the minimum degree to shoot for. At this level, you get some of the benefits of the eating clean diet plan but can still eat a few fast-food meals and the occasional junk food. Just try to make the nonclean 50% of your diet a bit healthier! Make homemade potato chips instead of eating processed, flavored chips; use multigrain pasta in place of white; and enjoy just one brownie rather than five. |
| 60% | Now you're getting more serious! At this level, most of your foods are clean and unprocessed, but you still eat processed foods two or three days a week. You have to do more cooking, but you're also saving money because you're eating out less and buying fewer processed (and expensive) foods. |
| 80% | Many people stop at this level of clean eating. The vast majority of your meals are clean, using whole, unprocessed foods, but you can still include some bottled pasta sauce and bakery bread in your diet. |
| 100% | Not many people can follow a true clean eating plan all the time, but if you can, bravo! If you've been diagnosed with a serious illness, this level may be the best option for you. Or if you're sick and tired of feeling sick and tired, the pure eating clean plan may help you feel better. |
