Creator's claim on three habits and aging
The description is attributed to Dr. Shayna Peter, described as a longevity physician and author. She states that exercise, intermittent fasting and supplements can support healthy aging. However, she says that when a routine is not matched to a person's individual physiology, such habits can sometimes add stress rather than resilience. The description does not name any measured outcome or study behind this statement.

Listed examples: overtraining, under-fueled fasting, supplement stacking

It also says the body may show signs of that stress in bloodwork before a person feels it. No specific blood marker, threshold or time frame is given.
