Can I do the Whole30, but modified?

We get some version of this modified Whole30 question just about every week. It sounds like this:

“Can I do the Original Whole30 but keep eating beans, as I know they work well for me?”
“Can I do the Plant-Based Whole30 but keep eating eggs for protein?”
“Can I do the Original Whole30 but keep eating rice and oatmeal to support my running?”

If this is your first Whole30, then YES, complete the program exactly as written, with no modifications.

If not... Melissa Urban’s response may surprise you. As with everything, there is some nuance, tap the link to find out more.
