Practice safety
Restrictive windows can cause hunger, headache, low energy or inadequate intake and may be inappropriate with pregnancy, eating disorders, frailty, adolescence or glucose-lowering medication without supervision.
Time-restricted eating confines daily energy intake to a consistent window, lengthening the fasting interval. Outcomes can reflect timing, reduced energy intake or both, and earlier and later windows may differ.
Purpose, evidence and practical considerations.
