You shouldn’t beat yourself up if you have one meal without all the nutrients you need. The healthiest mindset is for you to recognize that you’re going to be eating healthy for the rest of your life. It’s a lifestyle, not a month long quick fix. And consistency is what’s going to get you where you want to be.
That one meal won’t make or break your healthy lifestyle. But when you consistently eat unhealthy meals it will.
Small things add up, and the more consistent you can become with feeding yourself good foods, the closer you will be to your health goals
