SatietyCoach
Executive Summary
Vision Statement
Transform weight loss from hunger torture to sustainable satiety, empowering 100M+ dieters to lose fat without fighting their biology.
Problem Summary
Core Problem: Calorie-restricted dieters, especially vegetarians, experience extreme hunger despite consuming maintenance-level calories, leading to uncontrollable binges on low-satiety foods like fruit, mashed potatoes, and tortillas. Top comments reveal macro imbalances: insufficient fiber (168↑), protein (82↑, 62↑), and reliance on calorie-dense, low-volume foods.[Reddit Post]
Validation from Research: Plant-based weight loss fails without high-fiber, high-protein focus—90-95% of people lack recommended fiber intake, causing poor satiety.[1][7]
Proposed Solution
Satiety-First Nutrition Coach: AI-powered app that analyzes your daily intake, scores meals by satiety index (protein + fiber + volume / calories), and auto-generates swaps (e.g., 'Replace pineapple + tortillas with lentil soup + broccoli for 2x fullness'). Includes hunger coping tools: volume-eating recipes, distraction timers, and vegetarian-specific macro targets.[Reddit Comments][1][2]
Key Differentiation: Not just calorie tracking—satiety prediction prevents hunger before it hits.

Market Size Estimation
$15B Digital Nutrition Tracking (MyFitnessPal, Noom). Satiety-optimized niche unclaimed.
$500M Vegetarian Weight Loss Apps (r/loseit 1.2M x 10% conversion x $5/mo ARPU).
$78B Global Weight Loss Market (2023), growing 8% CAGR. Satiety subset: 40% of dieters report hunger as #1 failure reason.[Source]
Competitive Landscape
Direct: None focus on satiety scoring. MyFitnessPal tracks calories/macros but ignores hunger prediction.[Source]
Indirect:
- Noom ($4B valuation): Psychology coaching, no vegetarian satiety recipes. [noom.com]
- Lifesum: Macro templates, lacks AI swap suggestions.
- Cronometer: Nutrient tracking, no behavioral hunger tools.
Gap: No app scores/recommends by protein+volume/calories ratio with vegetarian focus.[1][2]
