You are not building a fitness app.
You are building:
a real-time decision engine for food
If outputs feel like advice, you lose
If outputs feel like decisions, you win
Your wedge order:
- Macro correction (primary entry)
- Damage control (retention engine)
- Fridge mode (support layer)
Everything revolves around:
"When your day goes off plan, get one exact next move in seconds."
DECISION ENGINE (NON-NEGOTIABLE)
Every output must follow:
- Identify the problem, what is wrong in their situation
- Apply constraint, what they ate or what they have
- Force correction, remove, reduce, replace, or add ONE thing
- Output Format: Next move: [specific action] Why: [specific reasoning tied to their situation]
QUALITY BAR (BURN THIS INTO YOUR BRAIN)
Bad:
"Try eating more protein"
Good:
"You had carbs without protein, that’s why you’re hungry again. Add 30g protein in your next meal."

COMMENT STRATEGY (THIS IS LIFE OR DEATH)
Never say: "I built something"
Always:
- Diagnose "You’re not actually overeating here, you just have no protein anchor after that meal."
- Explain "That’s why hunger spikes later."
- Ask "Want me to give you a quick next move for your case?"
14 DAY EXECUTION PLAN
DAY 1
Build MVP (2–4 hours max)
Single web page:
- 3 buttons (macro, messed up, what to eat)
- text input
- output (next move + why)
Then:
Post 10 HIGH QUALITY Reddit comments
Not generic. Diagnose each case.
Goal:
Get 3–5 replies
DAY 2
Reply to every comment
Send DM:
"Based on what you said:
Next move: X
Why: Y
Try here: [link]"
Track:
- who clicks
- who replies again
DAY 3
Improve outputs
Look at failures:
- where did it feel generic?
- where no "aha"?
Fix logic manually
Post 10 more comments
DAY 4
Introduce “aha enforcement”
Every output must:
- reveal something they missed
- simplify confusion
If not then rewrite
Talk to 5 users manually
DAY 5
Start continuity
If user returns:
"Last time you had no protein anchor. Did you try fixing that?"
Now product feels alive
DAY 6
Content starts
Post 2 short videos:
- "why you're always hungry after this"
- "this one mistake breaks your diet"
DAY 7
Evaluate:
Do any users return?
If NO:
Your outputs are weak
Fix decision engine, not UI
DAY 8
Push damage control mode harder
Find binge posts
Respond with:
calm + correction (not judgment)
DAY 9
Fridge mode integration
Use logic:
NOT:
"make this meal"
BUT:
"given what you ate + what you have, do this"
DAY 10
Add light feedback loop
"Was this helpful?"
Track yes/no
DAY 11
Identify repeat users
Message them:
"Want faster responses? I can prioritize you"
Build early core group
DAY 12
Add soft monetization test
ONLY if repeat usage exists
"Want unlimited daily fixes?"
Stripe link
DAY 13
Double down on best use case
If macro correction wins:
focus ONLY on that
Ignore rest temporarily
DAY 14
PMF CHECK
You only win if:
- users return without prompting
- users ask again
- users say "this helped me decide"
If not:
Your outputs are still advice, not decisions
FRIDGE MODE (FINAL CLARITY)
Fridge mode is NOT:
meal generator
It IS:
macro correction with constraints
Example:
Input:
"I have eggs, bread, cheese. Ate pasta earlier"
Output:
Next move:
Skip bread, do 3 eggs
Why:
You already had carbs, this balances protein
WHAT NOT TO DO
Do not:
- build full app
- add tracking
- add dashboards
- give multiple options
- sound like ChatGPT
FINAL RULE
Your entire startup depends on this:
Does your output feel like a decision?
If yes:
people return
If no:
they leave
DAILY MINIMUMS
Every day:
- 10 high-quality Reddit replies
- 3–5 DMs
- 5 real outputs tested
- 1 improvement to decision logic
Miss this = no progress
