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.

EDIT: In case anyone wants to sink their teeth into the topic, there's a very good book I read as part of my course work, called "Nutrition, 6th Edition" by Dr. Paul Insel; Don Ross; Kimberley McMahon; Melissa Bernstein. It's all very well sourced and kept up to date as modern science catches up. Available on AA if you don't want to buy it.

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.)

You make good points. I guess what I really wanted to say is that 90% of the time when people talk about toxins and try to offer up a solution, they don't even know what they're trying to talk about. There certainly are substances that bio-accumulate. And as you say, understanding what is actually there, what can be measured, what is problematic, and then reducing intake should be key in solving the issue.

Another thing I think is important to understand is that the science is continually evolving. I've encountered plenty of doctors who insist you should eliminate saturated fat from your diet as much as you can, and that's key to reducing your odds of heart disease. This is the old hypothetical model of heart disease. Modern studies tend not to agree. But people are still being told the same old things.
