Detoxes are scams.
If "The Plan" starts with one, skip it and move straight to the healthy balanced diet phase.
But if you're adamant you want to do it, you can replace foods you don't like with similar ones. If you don't like blueberries, do you like any other berries? Beets are a root veg, so how about carrot, sweet potato, or parsnip?
But the best idea is to skip the detox. It's a myth, a scam, a fad, and completely unhealthy.
