I believe toxin would be something that the body isn’t suppose to have in its system. Artificial sweetners, synthetic drugs, McDonalds, conventionally grown foods, oral steroids, etc.
Who is to say what is “supposed” to be in the body and what isn’t?
Of course we didn’t evolve eating McDonalds and taking steroids. That doesn’t automatically translate into them being unhealthy in and of themselves.
I have read somewhere that Galen, Paracelsus and Hippocrates “prescribed” fasting as a way of healing the body.
Non-peer review science from 2500 years ago. I’m going to base my health decisions around that.
I’m not saying fasting is the answer. It’s just an idea that has been around for centuries for healing the body and might be good for the body.
A lot of ideas have been around for centuries. That is only a measure of how infectious a bad idea is to a naive brain, not of how good the idea is.
One thing to note is that fasting, while certainly a preoccupation of people for centuries (millienium even), has always been something the rich and bored do. It is the affluent who have the time (and spare calories) to buy into whacko ideas that don’t enhance survival. Poor people have traditionally fasted not by choice. They also, generally, have much lower quality of life, more health problems and lower life expentancy. So if you went to various time points throughout history and offered poor people 3 meals for the day or the opportunity to continue starving to further their health, what do you think they’re going to do?
Beyond that, the entire idea is based on utterly wrong biology. Your body is very efficient at removing things that shouldn’t be in there while you’re eating. You don’t need to stop eating to get it to remove waste products. These basic functions are conserved throughout all animals and are not fasting dependent. In fact, if there were actually any biological advantage to fasting we’d see it in many other animals and we’d actually biologically be required to fast. That is, we’d expect that we would have the overwhelming desire to not eat periodically, no matter if we were in caloric defecit or surplus.
With the average gym-goer building muscle at 1-2 pounds of lean muscle/month (if that), I don’t think a day or a few days would put them back any, if it did at all.
Well if losing those some non-trivial fraction of that lean muscle every time you fast isn’t a set back to you, then no, it won’t set you back.[/quote]
Actually,in the wild,when animals are sick they quit eating and fast.I’ve seen it when I worked with wild life.
