A “reset” does not mean cleansing the gut or removing every microorganism. It means supporting the everyday conditions that help digestion and the wider body function: nourishing meals, enough fluids, movement, sleep and attention to stress.
Food quality and variety can be adjusted gradually. Fibre-rich foods may be useful for many people, but needs and tolerance differ. Sudden, restrictive changes can make symptoms harder to interpret.
If symptoms persist, work with a qualified health professional to look for causes and choose changes that fit your situation. Avoid detox claims or protocols that promise to reset the microbiome in a fixed number of days.
