Meal Planning

5 prompts

Macro-Targeted Meal Plan

1/18

✨ What it does

Creates 7-day macro-targeted meal plans with grocery lists and prep tips.

Create 7-day meal plan. Macros: [protein / carbs / fat targets]. Calorie target: [number]. Dietary preferences: [describe]. Restrictions: [allergies, dislikes]. Cooking time max: [minutes]. Deliver: 7 days with breakfast, lunch, dinner, 2 snacks, actual macro breakdown per meal, grocery list organized by section, prep-ahead tips.

💡

Pro tip: Macros without calorie target = inconsistency. Calculate BMR + TDEE first (Mifflin-St Jeor formula), then macros. Guessing macros leads to weight plateaus and frustration.

Macro Calculator

2/18

✨ What it does

Calculates personalized macros with BMR, TDEE, and goal-adjusted targets.

Calculate my macros. Stats: age [X], weight [Y], height [Z], activity level [sedentary/moderate/active]. Goal: [lose fat / build muscle / maintain]. Deliver: BMR, TDEE, target calories, macro breakdown (protein g/kg body weight), carb/fat split, eating window suggestion if relevant. Actionable numbers.

💡

Pro tip: Protein at 0.8-1g per lb bodyweight for fat loss; 0.7-0.9g for maintenance. Hit protein first, fill remaining calories with carbs + fats per preference. Protein first = sustainable.

High-Protein Meals

3/18

✨ What it does

Generates 15 high-protein meals (40g+) across protein sources and prep times.

Generate 15 high-protein meals (40g+ protein each). Dietary preferences: [describe]. Include: chicken, fish, beef, plant-based options. Per meal: ingredients, protein grams, calories, prep time, how to vary. Mix of savory + sweet, easy + effortful.

💡

Pro tip: Most people hit protein targets at dinner and miss at breakfast. 40g-protein breakfasts (Greek yogurt + whey + berries, eggs + cottage cheese) change the game.

Meal Prep Sunday

4/18

✨ What it does

Plans Meal Prep Sunday with cooking order, storage, and variety.

Meal prep Sunday plan. Time: [hours]. Number meals: [count]. Macro targets: [describe]. Include: shopping list, cooking order (most time-intensive first), storage/portioning, reheating instructions per meal, variety across week (avoid "same lunch 5 days"), backup pantry meals.

💡

Pro tip: Meal prep works when prepped meals vary. Chicken + rice + broccoli for 5 days = quit by Wednesday. Prep components (protein, carbs, veggies) + assemble varied lunches. Sustainable.

Eating Window / IF Plan

5/18

✨ What it does

Plans intermittent fasting with eating window, social events, and transitions.

Plan intermittent fasting schedule. Goal: [describe]. Lifestyle: [work hours, exercise timing]. Include: eating window (16:8, 18:6, OMAD), breakfast vs skip-breakfast IF, how to handle social events, coffee/drinks during fast, breaking fast foods, transition plan. Evidence-based.

💡

Pro tip: IF works for some, backfires for others. Women under-eat on IF more than men. Energy crashes = eat earlier. Listen to body; IF isn't universally optimal.

Dietary Restrictions

5 prompts

Vegetarian Macro Hit

6/18

✨ What it does

Plans vegetarian/vegan macro hitting with absorption, nutrients, and supplementation.

Hit macros as vegetarian. Targets: [protein, calories]. Vegan or vegetarian? Include: high-protein plant sources ranked by absorption, protein-per-$ efficiency, vitamin B12/iron/zinc consideration, daily meal structure hitting targets, supplementation if needed.

💡

Pro tip: Vegetarians miss iron + B12. Vegans also miss zinc + omega-3. Supplement proactively; don't wait for deficiency. Blood test yearly if plant-based long-term.

Keto Diet Plan

7/18

✨ What it does

Creates 7-day keto meal plans with electrolyte management.

7-day keto plan. Macros: <20g net carbs, 70-75% fat, 20-25% protein. Calorie target: [number]. Include: breakfast (easy, high-fat), lunch, dinner, fat bombs/snacks, grocery list, what to avoid (hidden carbs), electrolyte management (keto flu prevention).

💡

Pro tip: Keto flu (first 2 weeks) is salt + water depletion. 4-6g sodium daily + plenty of water + magnesium/potassium prevents headaches and fatigue.

Gluten-Free Made Simple

8/18

✨ What it does

Makes gluten-free eating simple without sugar-heavy substitutes.

Gluten-free eating without weight gain. Common mistake: replacing wheat with sugar-heavy GF substitutes. Include: naturally GF foods, avoiding processed GF junk, macro-balanced GF meals, restaurant navigation, hidden gluten, cross-contamination for severe celiac.

💡

Pro tip: GF packaged foods often contain more sugar/fat than regular. Naturally GF foods (rice, potatoes, meat, vegetables) > processed GF substitutes. Simpler + healthier + cheaper.

Plant-Based Transition

9/18

✨ What it does

Plans plant-based transitions with phased approach and nutrient management.

Transition to plant-based diet over [timeframe]. Starting point: [current eating]. Include: phased reduction of animal products, protein replacement strategy, social eating management, nutrient tracking (B12, iron, omega-3), avoiding vegan junk food trap, reality-checking motivations.

💡

Pro tip: Plant-based transitions succeed gradually. "Vegan overnight" has high failure rates. Start with 2-3 plant-based days/week, build to 7. Sustainable transition > perfect attempt.

FODMAP / IBS Navigation

10/18

✨ What it does

Navigates FODMAP protocol for IBS with elimination, reintroduction, and dining.

Navigate FODMAP for IBS symptoms. Phase: [elimination / reintroduction / long-term]. Include: elimination phase foods allowed, reintroduction testing protocol, identifying personal triggers, meal ideas within restrictions, dining out strategy, working with dietitian suggestion.

💡

Pro tip: Low-FODMAP elimination phase = 2-4 weeks, not forever. Reintroduce systematically to find YOUR triggers. Permanent restriction unnecessarily limits diet. Work with dietitian if symptoms persist.

Shopping & Label Reading

4 prompts

Grocery List by Goal

11/18

✨ What it does

Builds grocery lists aligned to goals with budget and whole-food focus.

Build grocery list aligned to [goal]. Budget: [amount/week]. Household: [size]. Include: proteins (best $/g), carbs (whole food focus), fats (healthy sources), vegetables (seasonal), fruits, pantry basics, occasional treats (realistic, not restrictive). Shop the perimeter.

💡

Pro tip: Shop perimeter of grocery store — produce, meat, dairy. Avoid middle aisles (processed). Rule: ingredient list over marketing. Short ingredient lists = real food.

Nutrition Label Decoder

12/18

✨ What it does

Decodes nutrition labels with serving sizes, hidden sugars, and claim skepticism.

Teach me to read nutrition labels. Include: serving size trap (multiply if eating more), added sugar vs natural, "low fat" = high sugar trick, fiber significance, sodium awareness, understanding ingredient order, hidden names for sugar (20+ names), health claim BS.

💡

Pro tip: "Healthy" labels are marketing. Ingredient list is truth. If sugar is in top 3 ingredients by any name (corn syrup, dextrose, fructose) = candy. Period.

Protein Per Dollar Ranking

13/18

✨ What it does

Ranks protein sources by cost-effectiveness with versatility notes.

Rank protein sources by $ per gram of protein. Include: eggs, chicken thighs/breast, ground beef, canned tuna, whey protein, Greek yogurt, cottage cheese, beans, lentils, tofu. Per source: protein per serving, calories, price, versatility. Budget-optimized protein.

💡

Pro tip: Cheapest proteins (eggs, chicken thighs, cottage cheese, canned tuna, whey) win budget battles. Skip "lean beef" and "salmon" daily — unnecessary premium for macro goals.

Restaurant Macro Estimation

14/18

✨ What it does

Estimates restaurant meal macros with modification suggestions.

Estimate restaurant meal macros. [Describe dish]. Include: likely calorie range, protein estimate, carb/fat estimate, sodium warning, modifications to reduce/adjust (sauce on side, double vegetables), ordering for goals. Imperfect but useful tracking.

💡

Pro tip: Restaurant meals are 30-50% higher calorie than same dish cooked at home. Double your estimate when guessing. Eating out 2×/week = 500+ extra cal/week tracking gap.

Troubleshooting & Science

4 prompts

Plateau Breaking

15/18

✨ What it does

Breaks weight plateaus with calorie audits, refeeds, and diet breaks.

Break weight loss plateau. Current: [describe diet/exercise]. Weeks stalled: [count]. Include: calorie creep check (weigh all food for 1 week), metabolic adaptation reality, refeed day strategy, exercise variation, sleep + stress audit, 2-week diet break (maintenance) if warranted.

💡

Pro tip: Plateaus are 80% calorie creep (unreported snacks, oils while cooking, drinks). Weigh everything for 1 week — shocking what you find. Fix reporting; plateaus break.

Food Sensitivity Investigation

16/18

✨ What it does

Investigates food sensitivities with elimination, journaling, and reintroduction.

Investigate food sensitivities. Symptoms: [describe]. Include: elimination diet protocol, food journal approach, common culprits (dairy, gluten, FODMAPs, eggs, nightshades), reintroduction testing, when to see allergist/dietitian, distinguishing sensitivity from allergy.

💡

Pro tip: Food sensitivity tests (blood, hair) are mostly unreliable. Elimination + reintroduction is gold standard. 4-week elimination → reintroduce one food at a time over weeks.

Hydration Optimization

17/18

✨ What it does

Optimizes hydration with calculated targets and electrolyte considerations.

Optimize hydration. Weight: [X]. Activity: [describe]. Climate: [describe]. Include: daily target (half bodyweight in oz rule), electrolyte needs (active, hot weather), water vs other fluids, hydration timing (morning, pre-workout), signs of dehydration, overhydration risks (rare).

💡

Pro tip: Half-bodyweight-in-oz rule gets most people to optimal. Active + hot climate = more. Electrolytes matter for athletes; water-only dilutes sodium during long exercise.

Supplements Worth It?

18/18

✨ What it does

Evaluates supplements worth taking with evidence-based recommendations.

Which supplements actually worth it? Current diet: [describe]. Goals: [describe]. Include: evidence-based supplements (creatine, whey, vitamin D, omega-3, magnesium), overhyped supplements to skip, personalized based on diet gaps, third-party tested brands, when blood test first. Evidence-first.

💡

Pro tip: Creatine + vitamin D + omega-3 + magnesium = most-researched effective supplements for most people. Everything else is 90% marketing. Save money on BCAAs, fat burners, "testosterone boosters."

Frequently Asked Questions

No — for medical conditions (diabetes, kidney disease, eating disorders) work with registered dietitian. For general healthy eating and macro planning, ChatGPT provides evidence-based guidance. Use AI for education, humans for diagnosis and medical intervention.
Not forever, but 2-4 weeks of tracking teaches portion awareness. Most people underestimate intake by 20-40%. After learning, intuitive eating possible. Complete strangers to nutrition benefit most from initial tracking.
The one you'll stick to for years. Keto, vegan, paleo, Mediterranean — all work if sustained. Ignore "optimal" debates; prioritize adherence. Boring consistent diet > perfect unstainable diet.
0.7-1g per pound bodyweight for active adults (weight training, athletics). 0.5-0.7g for sedentary maintenance. Higher ranges for fat loss (preserves muscle) and aging adults. Most under-consume protein.
Mostly marketing. Blueberries are great; so are apples. Açaí is good; so is raspberries. Eat variety of whole foods; don't chase exotic expensive superfoods. $5 of frozen berries > $15 of açaí bowl.
