Functional nutrition
Plans that start with causes, not calorie counts.
Bangladeshi food first
Bhat, dal, shak, machh and your own kitchen.
Dietitian in charge
AI drafts and explains. A professional can review.
Most diet apps count calories. Functional nutrition asks what is behind the tiredness, the bloating, the cravings, then builds the plan around that.
Pick one you notice.
What we look at first
- Meal balance at lunch
- Refined carbs and sugary tea
- Sleep the night before
Food moves to try
- Pair bhat with dal and shak, not alone
- Start the day with protein: egg or chola
- Move the sweet tea after the meal
Examples of how functional nutrition thinks, not a diagnosis. Persistent symptoms deserve a doctor's visit.
- 1
Tell us how you feel
Energy, digestion, sleep, goals, what is in your kitchen. Add lab reports if you have them.

We look for patterns
Sustho connects symptoms, habits and nutrient gaps using a functional nutrition framework.

Adjust every week
Check in, ask questions, swap meals. Your plan changes as your body responds.
Who we are building for.
Five everyday situations and two professionals. They are illustrative personas, not customers.
Rahima, 34
Working mother, Dhaka
Tired by 3 pm and skips breakfast. Wants meals her whole family can eat.
Tanvir, 27
Software engineer, Chattogram
Eats at his desk, often bloated, sleeps late. Wants simple changes that fit a work day.
Nasrin, 58
Retired teacher, Sylhet
Wants to manage her blood sugar through food, alongside her doctor's advice.
Arif, 22
University student, Rajshahi
Hostel food and a tight budget. Wants steady energy for exams and the gym.
Sumon, 41
Bangladeshi abroad, London
Misses home cooking. Wants a plan built from what he can buy in local shops.
Images are AI-generated and show fictional people.
Dietitians like you.
Ayesha Rahman, 36
Solo dietitian, Dhaka
Spends evenings on paperwork. Wants time back for her clients.
Kamal Hossain, 52
Runs a nutrition clinic, Khulna
Leads four dietitians. Wants consistent plans and records across the team.
Generic apps do not know pui shak from spinach or what a katori of dal holds. We build the food database, portions and recipes around Bangladeshi meals first, then extend across South Asia.
- Every plan can be reviewed by a qualified dietitian
- AI shows why it suggested each change
- Medical red flags are sent to a doctor, not a chatbot
- Your health data stays yours
