Fasting tailored to your unique body.

During a true fast, stick to water, plain black coffee, or unsweetened tea. Anything with calories — including milk, cream, sweeteners, or broth with fat — can raise insulin and break the fast. If you need electrolytes, use a zero-calorie option without sugar.

A common starting point is 12–14 hours overnight. Many people progress to 16:8 (16 hours fasting, 8 hours eating). Longer fasts such as 18:6 or 20:4 can be effective, but the right length depends on your experience, health, and daily schedule. PickAReset builds a window around your body, not a generic template.

Break your fast when your planned eating window begins, or when you feel genuinely hungry rather than bored or stressed. Start with something light — protein, vegetables, or a small balanced plate — and wait 20–30 minutes before a larger meal to avoid bloating or an insulin spike.

Yes, black coffee and plain tea are generally fine. Caffeine can even support fat burning and alertness. Avoid adding sugar, milk, cream, or flavored syrups. If caffeine makes you jittery on an empty stomach, switch to herbal tea or half-caff.

Short-term fasting does not crash metabolism. In fact, brief fasts can improve insulin sensitivity and metabolic flexibility. Prolonged or very restrictive fasting without refeeding can be counterproductive, which is why PickAReset pairs every fast with a structured refeed blueprint.

Fasting is not recommended during pregnancy or breastfeeding, for people with a history of eating disorders, or for those with certain medical conditions or on specific medications. If you are unsure, speak with a healthcare professional before starting any fasting protocol.
