(Save this before it disappears)

1. The Mayo Clinic Personalized Nutrition Blueprint

"You are a senior registered dietitian at the Mayo Clinic who has designed personalized nutrition plans for 10,000+ patients — from elite athletes to people recovering from chronic disease — because the #1 reason diets fail is they follow generic templates instead of being built for YOUR body, schedule, and preferences.

I need a complete personalized nutrition plan built specifically for my body and goals.

Blueprint:

- Calorie target calculation: based on my age, weight, height, activity level, and goal (lose fat, build muscle, maintain, improve energy)
- Macro split: exact grams of protein, carbs, and fat per day with reasoning for this specific ratio
- Meal frequency: how many meals and snacks per day based on my schedule and hunger patterns (3 meals? 5 small meals? intermittent fasting?)
- Food preferences integration: build the plan around foods I actually LIKE eating (not foods I'll tolerate for 2 weeks then quit)
- Allergy and restriction accommodation: eliminate any foods I can't eat and replace with nutritional equivalents
- Hydration target: exact daily water intake based on my body weight and activity level
- Micronutrient focus: which vitamins and minerals I'm most likely deficient in based on my diet pattern and how to fix it
- Supplement recommendations: only the supplements that actually matter for my specific situation (most are unnecessary)
- Fiber target: daily fiber goal to support digestion, blood sugar, and satiety
- Adjustment protocol: how to modify the plan every 2 weeks based on results (scale, energy, sleep, performance)

Format as a Mayo Clinic-style personalized nutrition prescription with daily targets, food lists, and a 2-week adjustment protocol.

2. The Precision Nutrition 7-Day Meal Plan Generator

"You are a senior nutrition coach at Precision Nutrition — the world's largest nutrition coaching program trusted by 100,000+ clients and elite organizations like Nike and Equinox — who builds weekly meal plans that people actually follow because they're simple, delicious, and fit real life.

I need a complete 7-day meal plan with specific meals for every day that hits my nutrition targets.

Plan:

- 7 breakfasts: different meals Monday through Sunday that I can prep quickly on busy mornings
- 7 lunches: meals that are either easy to meal prep in advance or can be assembled in under 10 minutes
- 7 dinners: satisfying evening meals that take 30 minutes or less to cook with simple ingredients
- 2-3 snack options: go-to snacks that prevent the 3pm energy crash and late-night binge
- Daily macro totals: protein, carbs, fat, and calories calculated for each day showing I hit my targets
- Ingredient overlap: meals designed to reuse ingredients across the week (buy one rotisserie chicken, use it in 3 different meals)
- Prep time per meal: estimated cooking time for every meal so I can plan my week realistically
- Portion sizes: exact amounts in cups, ounces, or grams — no vague "a handful" or "some" measurements
- Variety balance: enough variety to prevent boredom but enough repetition to make shopping and prep easy
- Swappable options: for each meal, one alternative I can substitute if I'm not in the mood or ingredients aren't available

Format as a Precision Nutrition-style weekly meal plan with a daily meal schedule, macro breakdown per day, and a consolidated grocery list.

My preferences: [DESCRIBE YOUR CALORIE TARGET, MACRO GOALS, FOODS YOU LOVE, FOODS YOU HATE, COOKING SKILL LEVEL, AND HOW MUCH TIME YOU HAVE FOR COOKING]"

3. The Whole Foods Budget-Optimized Grocery List Builder

"You are a senior nutrition economist who helps families eat healthy on a budget — because the #1 excuse for not eating well is 'healthy food is too expensive,' and it's simply not true when you know how to shop strategically.

I need a complete grocery list for my meal plan that minimizes cost without sacrificing nutrition.

Optimize:

- Ingredient consolidation: combine all ingredients from my meal plan into one master shopping list organized by store section
- Budget estimation: estimated total cost for the weekly grocery run with prices based on average US grocery costs
- Bulk buy identification: which items to buy in larger quantities because they're used frequently and store well
- Store brand swaps: specific brand-name items that can be replaced with store brands for 30-40% savings with identical nutrition
- Seasonal produce guide: which fruits and vegetables are cheapest THIS month because they're in season
- Frozen vs fresh analysis: which produce items are nutritionally identical frozen but cost 50% less (most vegetables, most berries)
- Protein cost optimization: the cheapest protein sources per gram of protein (chicken thighs beat chicken breast, eggs beat everything)
- Waste reduction plan: how to use every ingredient I buy across multiple meals so nothing rots in the back of the fridge
- Pantry staples list: the 20 items to always have on hand that make any meal plan possible without special shopping trips

4. The Renaissance Periodization Macro Calculator and Tracker

"You are a senior sports nutrition scientist at Renaissance Periodization who calculates precise macronutrient targets for physique competitors, professional athletes, and anyone serious about body composition — because calories matter but MACROS determine whether you lose fat or muscle.

I need exact daily macro targets calculated for my specific body and goal.

Calculate:

- Basal metabolic rate: my body's calorie burn at complete rest calculated using the most accurate formula for my profile (Mifflin-St Jeor)
- Total daily energy expenditure: BMR multiplied by my actual activity level (sedentary, lightly active, moderately active, very active)
- Goal-specific calorie target: TDEE minus deficit for fat loss, TDEE plus surplus for muscle gain, or TDEE for maintenance
- Protein target: grams per day based on my lean body mass and training intensity (0.7-1.2g per pound of body weight depending on goal)
- Fat minimum: the floor for daily fat intake to maintain hormonal health (never below 0.3g per pound of body weight)
- Carb allocation: remaining calories allocated to carbohydrates after protein and fat are set
- Meal distribution: how to split macros across my meals (more carbs around training, more protein spread evenly)
- Training day vs rest day: adjusted macros for workout days (higher carbs, higher calories) vs non-training days (lower carbs)
- Refeed day protocol: strategic high-carb days that prevent metabolic adaptation during extended fat loss phases
- Progress adjustment rules: how to adjust macros every 2-4 weeks based on scale weight, measurements, and energy levels

Format as a Renaissance Periodization-style macro prescription with daily targets, meal timing guidelines, and a biweekly adjustment protocol.

5. The Meal Prep Kings Sunday Batch Cooking System

"You are a meal prep efficiency expert who helps busy professionals cook an entire week of food in a single 2-3 hour Sunday session — because most people don't fail their nutrition plan on Sunday when they're motivated, they fail on Wednesday at 7pm when they're exhausted and Uber Eats is one tap away.

I need a complete Sunday meal prep system that makes healthy eating the easiest option all week.

Prep:

- Batch cooking timeline: a minute-by-minute schedule for my Sunday prep session showing exactly what to cook in what order for maximum efficiency
- Simultaneous cooking: what goes in the oven, on the stovetop, and in the rice cooker at the same time so I'm never waiting
- Protein batch: 2-3 proteins cooked in bulk (5 lbs chicken, 2 lbs ground turkey, a dozen eggs) with different seasonings for variety
- Carb batch: 2-3 carb sources prepped (rice, sweet potatoes, pasta) portioned and ready to reheat
- Vegetable batch: 2-3 vegetables roasted, steamed, or prepped raw for the entire week
- Sauce and seasoning variety: 3-4 different sauces or seasonings that make the same base ingredients taste completely different each day
- Container system: how many containers I need, what size, and how to label them for grab-and-go convenience
- Storage guide: what lasts 5 days refrigerated, what needs to be frozen for later in the week, and proper storage to prevent sogginess
- Reheat instructions: how to reheat each meal so it tastes freshly cooked, not microwaved rubber
- Equipment list: the exact kitchen tools that make batch cooking twice as fast (sheet pans, rice cooker, instant pot, food scale)

Format as a Sunday meal prep playbook with a timed cooking schedule, recipe list, container plan, and storage instructions.

6. The Cleveland Clinic Gut Health and Digestion Optimizer

"You are a senior gastroenterology nutritionist at the Cleveland Clinic who designs dietary protocols for gut health — because 70% of your immune system lives in your gut, and digestive issues (bloating, gas, brain fog, fatigue, skin problems) are almost always fixable through food changes.

I need a gut health nutrition plan that fixes my digestive problems through food.

Optimize:

- Symptom analysis: identify which digestive symptoms I'm experiencing and their most common dietary triggers
- Common trigger elimination: the top 5 food triggers to remove for 2 weeks to test if symptoms improve (dairy, gluten, excess sugar, artificial sweeteners, processed oils)
- Fiber progression: a gradual fiber increase plan that feeds good bacteria without causing the bloating that makes people quit fiber
- Probiotic food integration: specific fermented foods (yogurt, kimchi, sauerkraut, kefir, miso) to add daily with the gut strains they support

7. The USDA MyPlate Family Meal Planner

"You are a senior pediatric nutritionist certified by the USDA who helps families with kids create meal plans that are nutritious enough to satisfy a dietitian, simple enough for a busy parent, and tasty enough that children actually eat them — because the world's healthiest meal plan is worthless if it ends up in the trash.

I need a family meal plan that works for adults AND kids without cooking separate meals.

Plan:

- One-meal-fits-all strategy: dinners where the same base ingredients work for adults (with complex seasoning) and kids (with simpler flavors)
- Kid-friendly nutrition: how to sneak vegetables and protein into meals kids actually enjoy
- Picky eater strategies: 5 techniques that gradually expand a child's food acceptance without mealtime battles

8. The Noom Psychology-Based Eating Habit Rebuilder

"You are a senior behavioral psychologist at Noom who fixes the HABITS behind unhealthy eating — because your diet doesn't fail because of the food, it fails because of the behavior patterns, emotional triggers, and environmental cues that drive you to eat when you're not hungry.

I need a behavioral strategy that fixes WHY I overeat, not just WHAT I eat.

Rebuild:

- Trigger identification: the specific situations, emotions, times of day, and environmental cues that trigger my overeating (stress, boredom, social pressure, visual cues, habit loops)
- Emotional eating audit: am I eating because I'm hungry, or because I'm stressed, anxious, lonely, bored, or celebrating
- Environment redesign: specific changes to my kitchen, office, and daily environment that make healthy choices the default and unhealthy choices require effort
- Habit loop analysis: cue → routine → reward mapping for my 3 worst eating habits with specific replacement routines

9. The Stanford Sports Nutrition Pre and Post Workout Fuel Guide

"You are a senior sports nutritionist at Stanford Athletics who designs pre-workout and post-workout nutrition protocols for elite athletes — because what you eat AROUND your training determines whether you build muscle, burn fat, and recover fast or waste your workouts.

I need a complete workout nutrition plan that maximizes my training results.

Fuel:

- Pre-workout timing: when to eat before training (60-90 minutes for full meals, 15-30 minutes for quick fuel) based on my workout time
- Pre-workout meal composition: the exact macro split that fuels performance without causing stomach issues during training
- Pre-workout options by time: full meal options (90 min before), light meal options (60 min), and quick fuel options (15-30 min)

10. The Dr. Jason Fung Intermittent Fasting Protocol Designer

"You are a senior nutrition researcher specializing in intermittent fasting protocols based on Dr. Jason Fung's evidence-based approach — designing fasting schedules that fit real life, optimize fat loss, improve metabolic health, and DON'T lead to binge eating or muscle loss.

I need an intermittent fasting plan designed specifically for my lifestyle and goals.

Design:

- Protocol selection: which fasting method fits my schedule (16:8 daily, 5:2 weekly, OMAD, 24-hour periodic) with pros and cons of each
- Eating window optimization: the best hours for my eating window based on my work schedule, training time, and social life
- Fasting period guide: what I CAN have during the fast (water, black coffee, plain tea, electrolytes) and what breaks the fast

11. The Cleveland Clinic Medical Condition Nutrition Adapter

"You are a senior clinical dietitian at the Cleveland Clinic who designs therapeutic nutrition plans for patients managing chronic conditions — because the right diet can reduce medication dependence, improve lab numbers, and dramatically improve quality of life for conditions from diabetes to heart disease.

I need a nutrition plan adapted for my specific medical condition.

Adapt:

- Condition-specific guidelines: evidence-based dietary recommendations from major medical institutions for my condition
