Choose Your Schedule
5 promptsPick a fasting method
1/20Help me choose an intermittent fasting method for my life: [work hours, wake/sleep times, goal, experience]. Include: 2-3 methods (like 16:8 or 14:10), pros and cons of each for me, and which to start with and why.
Recommends a fasting method matched to your schedule and goal.
Pro tip: Start with the gentlest window (like 14:10) and tighten it later — an aggressive first schedule is the fastest way to quit.
Map your eating window to your day
2/20I want to try [method, e.g. 16:8]. My day: [wake, work, workout, sleep times]. Include: the exact fasting and eating window times that fit my routine, and which meals fall inside the window.
Sets concrete fasting and eating window times around your day.
Pro tip: Anchor your eating window to your biggest social or family meal so fasting fits your life instead of fighting it.
Ease into fasting gradually
3/20I'm new to intermittent fasting and want to ramp up gently. Goal: [method]. Include: a week-by-week plan that slowly extends my fast, what to expect each week, and when to slow down if it feels too hard.
Builds a gradual, week-by-week ramp into a fasting schedule.
Pro tip: Extend the fast by 30-60 minutes at a time — a gradual ramp lets your hunger hormones adjust without a rough week.
Fit fasting around workouts
4/20I train [when and what type]. Help me schedule fasting so I have energy to train and recover. Include: whether to eat before or after, where to place my window, and how to adjust on heavy training days.
Aligns your fasting window with training for energy and recovery.
Pro tip: If you train hard, put a meal near your workout — chronically training fasted can sap performance and recovery.
Weekend and social-friendly schedule
5/20Help me follow intermittent fasting without missing social meals. My social eating happens [when]. Include: a flexible weekly schedule, how to shift my window for events, and a rule for weekends so I don't feel restricted.
Creates a flexible schedule that bends around social meals.
Pro tip: Shifting your window for an event beats skipping it — flexibility is what makes fasting sustainable long-term.

Plan Your Meals
5 promptsMeals that keep you full
6/20Plan meals for my eating window ([window length]) that keep me full through the fast. Preferences: [likes/dislikes, restrictions]. Include: high-protein, high-fiber meal ideas and why each helps with hunger.
Suggests filling, satiating meals to bridge the fasting window.
Pro tip: Front-load protein and fiber — they blunt hunger far longer than fast-digesting carbs when the window closes.
Break-fast meal ideas
7/20Suggest good meals to break my fast that won't spike energy then crash it. Restrictions: [any]. Include: 3-4 balanced options, why they're gentler on blood sugar, and portion guidance for the first meal.
Offers balanced first meals that avoid a post-fast energy crash.
Pro tip: Break your fast with protein and fat, not a big sugar hit — a gentler first meal avoids the mid-afternoon crash.
Fit your calories in the window
8/20Help me fit enough food into a [window length] eating window without overeating or undereating. My rough target: [calories or goal]. Include: how to split it across meals and a note on not bingeing at window open.
Structures your daily food sensibly across a shorter eating window.
Pro tip: A short window can lead to under- or over-eating — plan meals in advance so you don't overcorrect at the first bite.
What breaks a fast (and what doesn't)
9/20Explain in plain terms what typically breaks a fast versus what's usually fine (water, black coffee, tea, etc.), for someone fasting for [reason]. Include: a simple do/avoid list and where the gray areas are.
Clarifies which drinks and extras keep a fast versus break it.
Pro tip: Plain water, black coffee, and unsweetened tea are the safe staples — anything with calories is a gray area.
Weekly fasting meal plan
10/20Build a 7-day meal plan for my eating window with [restrictions] and rough target [calories/goal]. Include: meals per day inside the window, a short grocery list, and a couple of quick options for busy days.
Produces a full week of window-friendly meals with a grocery list.
Pro tip: Include a few 5-minute backup meals — a busy day with no plan is when fasting most often falls apart.
Troubleshoot
5 promptsBeat the hunger pangs
11/20I get strong hunger during my fast around [time]. Help me manage it. Include: likely reasons, zero- or low-calorie things that help, and habits to reduce hunger over time. Note when hunger means I should just eat.
Offers practical ways to ride out or reduce fasting hunger.
Pro tip: Fasting hunger comes in waves — hydration, black coffee, and staying busy usually carry you past the peak.
Fix low energy or brain fog
12/20I feel low-energy or foggy while fasting. Details: [when it hits, your schedule]. Include: common causes (hydration, electrolytes, too-fast a ramp), simple fixes, and signs I should shorten my fast or stop.
Diagnoses fasting fatigue and suggests simple, safe fixes.
Pro tip: Persistent fog or dizziness is a signal to ease off — fasting shouldn't leave you unable to function.
Handle headaches and cravings
13/20I get headaches and cravings when fasting. Include: likely triggers (dehydration, caffeine, blood sugar), practical prevention, and honest guidance on when it's a sign this schedule isn't right for me.
Addresses fasting headaches and cravings with prevention tips.
Pro tip: Early fasting headaches are often dehydration or caffeine timing — hydrate well before assuming it's the fasting itself.
Break a weight-loss stall
14/20My progress has stalled on [method] for [time]. Goal: [goal]. Include: common non-dramatic reasons, 2-3 sustainable things to check or adjust, and a reminder that extreme changes usually backfire.
Suggests measured adjustments when fasting results plateau.
Pro tip: Check portion creep in your window before changing your fast — more food often sneaks in than people realize.
Adjust for travel or a busy day
15/20My schedule is disrupted by [travel / late night / early start]. Help me adapt my fasting for the day without derailing. Include: a flexible plan, what to prioritize, and permission to skip fasting if needed.
Flexes your fasting plan around a disrupted or unusual day.
Pro tip: One off-schedule day changes nothing long term — adapt or skip, then return to normal without guilt.
Stay Consistent
5 promptsBuild a fasting routine that sticks
16/20Help me turn intermittent fasting into a sustainable habit. My past struggles: [what's tripped you up]. Include: 3 realistic habits, cues to anchor them to, and a plan for the moments I usually cave.
Turns fasting into durable habits anchored to daily cues.
Pro tip: Anchor your window to fixed daily cues (like your morning coffee) so fasting runs on autopilot, not willpower.
Track how you feel
17/20Design a simple daily fasting log I can keep. Include: a few things worth tracking (window kept, hunger, energy, sleep, mood) and how to review it weekly to see what's working — without obsessing over it.
Sets up a light daily log to learn what fasting pattern suits you.
Pro tip: Track mood, energy, and sleep, not just weight — how you feel is the real test of whether a schedule fits you.
Weekly fasting review
18/20Here's my fasting week: [paste your log or notes]. Include: what went well, where I struggled, any patterns in when I broke my fast, and one small adjustment for next week. Keep it encouraging.
Reviews your week of fasting and suggests one small tweak.
Pro tip: Look for patterns in when you slip (late nights? weekends?) — the fix is usually situational, not willpower.
Handle social pressure
19/20People question my fasting or push food at gatherings. Give me easy, non-defensive ways to handle it. Include: a couple of light responses, and how to shift my window so I can join meals without over-explaining.
Provides low-drama replies for social pushback around fasting.
Pro tip: You don't owe anyone an explanation — a light 'I'm good, not hungry yet' ends most questions instantly.
Restart after falling off
20/20I stopped fasting for [reason] and want to restart without the all-or-nothing spiral. Include: a gentle re-entry plan, a no-guilt reframe, and the single easiest first step to rebuild the habit this week.
Gives a gentle, guilt-free plan to restart fasting after a break.
Pro tip: Restart with an easier window than before — a small, winnable re-entry rebuilds momentum better than jumping back to the hardest plan.
