Matthew 6:16-18
BSB
16 When you fast, do not be somber like the hypocrites, for they disfigure their faces to show men they are fasting. Truly I tell you, they already have their full reward.
17 But when you fast, anoint your head and wash your face,
18 so that your fasting will not be obvious to men, but only to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you.

Early fasting hours: insulin begins to drop and glycogen use increases.
Later window: metabolic flexibility improves and cellular cleanup processes increase.
Many people report improved focus, but hydration and electrolyte balance matter.
Safety: if you are pregnant, diabetic, underweight, or on medication, get medical guidance first.
Fast to seek God, not to perform. Let body stewardship and prayer work together.
