Decades ago (pre-internet) I read about men that sat in caves in India and put their bodies into some super sloooooowed down state through meditation. They didn’t eat or drink water for months. If they were bitten by a venomous snake, it had no effect. It seemed like it couldn’t be real, and I never came across a mention of it again. This was some spiritual/religious practice.
The OP is about a school of Tibetan yoga called g-tummo, but there are many different schools which follow different practices and traditions, leading to different outward attainments. I can’t place exactly what you’re talking about, but those all sound like effects related to slowing down of the metabolism, which is common to most all deep meditative practices.
One interesting yogi to look up is Milarepa, if the less documented but more awe-inspiring stories strike your interest. He seems to have led an incredibly interesting life.

Maybe this is something similar?
