Water Fasting for Facial Definition
Acute water/glycogen loss masquerading as fat loss; rebounds within days and stresses everything else.
Also called: water fast · fasting for jawline · 48 hour fast
Verdict — cope
The mechanism does not hold. Your time is better spent elsewhere.
Evidence grade D
Nobody has demonstrated this works. Note that this grades the evidence, not the danger — read the verdict for that.
Mechanism
Multi-day fasts shed glycogen-bound water and sodium, temporarily deflating facial soft tissue — then it all returns on refeeding.

The full read
The 'fasted face' look is dehydration. Sustainable facial recomposition comes from a moderate deficit over months, preserving muscle with protein and training. Crash protocols also tank sleep and mood, hurting the metrics that actually compound. Same calories, spread sanely, same fat loss — without the rebound photos.
