How
TRYFI Works

Our assessment isn't a generic quiz. It captures the exact inputs our nutrition engine needs to calculate your metabolism with clinical accuracy:

• check_circleHeight, weight, date of birth, sex
• check_circleActivity category (sedentary → competitive athlete)
• check_circleWeekly training hours
• check_circleClinical flags: smoker status, pregnancy, deficiencies
• check_circleDietary constraints and food allergies
• check_circleYour goal — fat loss, hypertrophy, maintenance, or nutrition completion
• check_circleYour goal rate — aggressive (±20%) down to maintenance

The moment you submit, our engine runs:

1. Mifflin-St Jeor BMR — the most validated resting metabolic rate formula 2. Activity-adjusted TDEE — your total daily energy expenditure 3. Goal-rate caloric offset — calibrated surplus or deficit 4. Fixed macro split — 30% protein / 25% fat / 45% carbs (v1) 5. Micronutrient flag overlays — based on your clinical inputs

The result is your Prescription: target calories and exact gram-level macros for every day.

Your subscription locks in your prescription. We then:

• check_circleMatch your daily macro targets to our food catalogue
• check_circleBuild a 3-meal-a-day plan that hits your numbers
• check_circlePrepare meals fresh daily
• check_circleDeliver to your door on the timeslot you chose (Morning, Afternoon, or Evening)

You don't need to track, plan, or weigh anything. The meals arrive matching your prescription.

As your weight, activity, and goals shift, your prescription becomes stale. TRYFI prompts you for a new assessment on a schedule tied to your plan:

• check_circleCore: Monthly prompt
• check_circlePerformance: Bi-monthly prompt
• check_circleClinical: Quarterly (with full micronutrient panel review)

A new assessment triggers a new prescription, which our engine applies to your next delivery cycle automatically.
