This is not exactly true. It's a generalization.
Some health problems are genetic or environmental and outside of human control.
If your mother was toxic with chemicals when she gave birth to you, that's something you might suffer from your entire life and have little control over.
If you got some weird genes that make you more sensitive to chemicals in the food supply, that's also very difficult to control.
But also many health problems ARE within your control if you change your lifestyle.
It doesn't matter how conscious or woke you become, you can still have health problems. And many awakened people do. The body is easily broken.
BTW, I have improved my heath A LOT through improving my perception. If I hadn't done that, I would probably be dead by now.
The bottom line is: Consciousness of Absolute Truth or God will not give you good health.
