Choose Your Schedule
5 promptsPick a fasting method
1/20✨ What it does
Recommends a fasting method matched to your schedule and goal.
Help 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.
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
2/20✨ What it does
Sets concrete fasting and eating window times around your day.
I 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.
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
3/20✨ What it does
Builds a gradual, week-by-week ramp into a fasting schedule.
I'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.
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
4/20✨ What it does
Aligns your fasting window with training for energy and recovery.
I 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.
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
5/20✨ What it does
Creates a flexible schedule that bends around social meals.
Help 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.
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
6/20✨ What it does
Suggests filling, satiating meals to bridge the fasting window.
Plan 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.
Pro tip: Front-load protein and fiber — they blunt hunger far longer than fast-digesting carbs when the window closes.
Break-fast meal ideas
7/20✨ What it does
Offers balanced first meals that avoid a post-fast energy crash.
Suggest 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.
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
8/20✨ What it does
Structures your daily food sensibly across a shorter eating window.
Help 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.
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)
9/20✨ What it does
Clarifies which drinks and extras keep a fast versus break it.
Explain 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.
Pro tip: Plain water, black coffee, and unsweetened tea are the safe staples — anything with calories is a gray area.
Weekly fasting meal plan
10/20✨ What it does
Produces a full week of window-friendly meals with a grocery list.
Build 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.
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
11/20✨ What it does
Offers practical ways to ride out or reduce fasting hunger.
I 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.
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
12/20✨ What it does
Diagnoses fasting fatigue and suggests simple, safe fixes.
I 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.
Pro tip: Persistent fog or dizziness is a signal to ease off — fasting shouldn't leave you unable to function.
Handle headaches and cravings
13/20✨ What it does
Addresses fasting headaches and cravings with prevention tips.
I 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.
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
14/20✨ What it does
Suggests measured adjustments when fasting results plateau.
My 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.
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
15/20✨ What it does
Flexes your fasting plan around a disrupted or unusual day.
My 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.
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
16/20✨ What it does
Turns fasting into durable habits anchored to daily cues.
Help 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.
Pro tip: Anchor your window to fixed daily cues (like your morning coffee) so fasting runs on autopilot, not willpower.
Track how you feel
17/20✨ What it does
Sets up a light daily log to learn what fasting pattern suits you.
Design 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.
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
18/20✨ What it does
Reviews your week of fasting and suggests one small tweak.
Here'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.
Pro tip: Look for patterns in when you slip (late nights? weekends?) — the fix is usually situational, not willpower.
Handle social pressure
19/20✨ What it does
Provides low-drama replies for social pushback around fasting.
People 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.
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
20/20✨ What it does
Gives a gentle, guilt-free plan to restart fasting after a break.
I 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.
Pro tip: Restart with an easier window than before — a small, winnable re-entry rebuilds momentum better than jumping back to the hardest plan.
