If you want to try IF, start with a 12:12 schedule and extend the fasting window gradually only if you feel well. Water, plain tea, and black coffee are commonly used during a fast. Listen to your body and stop if you feel unwell.
Intermittent fasting is not a magic solution. It works best when paired with nutritious food choices and a routine you can sustain. If you take medication, have a medical condition, are pregnant or breastfeeding, or have a history of disordered eating, speak with a qualified clinician before changing your eating pattern.
