Chelation should only be considered if the immune barriers are in tact (i.e., no leaky gut, or leaky blood - brain barrier, which would allow chelated toxins into the brain), the immune system is balanced, and detoxification functions are working normally.

If leptin signalling is weak — ie, if our body fat levels are too low, or if we exercise too often — then the lack of leptin crossing the blood - brain barrier into the hypothalamus signals to the hypothalamus that the body is starving, and certain extraneous bodily functions such as reproduction cease.
