I would say #2, because it is very important to eat a well balanced diet while also working out and staying physically active to stay healthy! However, the question asks, "Which of the following is a guideline for practicing good nutrition." That being said I would say #4 "Consume foods with a variety of nutrients and adequate portions.
Hope this helps!
Yes because when you want something to be perfect you tend to try and imagine it beforehand so you know what to do perfectly and if you mess up you can imagine punching the person who messed you up :)
