I’m a personal trainer with certifications in fitness nutrition (I’m not a dietitian, those are actual licensed medical practitioners you go to see about dietary needs. I can legally provide guidelines, but I can’t prescribe meal plans.)

Our body is great at getting rid of toxins and waste products. It’s almost as if we’ve evolved ways of dealing with such things. Anyone talking about “toxins” and “waste products” as if they’re ‘stuck’ in your body is either very ignorant, or trying to sell you snake oil. Probably both. I’ve seen a lot of it, especially in my profession. People making up bullshit to sound knowledgeable and sell you something you don’t need. And yeah, a lot of trainers are just as ignorant and just trying to sell you something you don’t need.

There are bio-accumulative toxins that really do get stuck in your body. Lead is a good example. Not that the supposed cures being peddled by these people can actually do anything about those.

Also, for the normal kind of toxin, the biggest factor keeping the levels in your body high is continued intake. Reducing that totally makes sense. However, you need to first have a real, based on science, understanding of what those toxins are in the first place and not just randomly blame junk food or 5G radiation, and it needs to be a permanent life style change. A two week “cleanse” does nothing. A juice will not detoxify you. (Depending on the juice, especially how filtered and how sugary it is, it may be healthy for other reasons. Standard orange juice is not, it’s way too sugary.)
