Democracy in menu planning at a restaurant

Summary

A portion-aware menu planning and ordering terminal supports a hybrid restaurant and diet clinic. Dieticians can plan menus and demonstrate what a meal looks like at a specific portion size. Customers then practise that skill in context by ordering from a menu the kitchen can execute consistently, while still protecting restaurant margins.

Background

I am a registered dietitian with a career in tech. I have long wondered how I could bring a unique perspective to nutrition and technology with my background. In this showcase, I explored how nutrition education and restaurant operations could be integrated into a digital product that brings the hospital kitchen model to the public.

Problem

Ecosystem map: Nutrition education and restaurant ordering operate in silos, so counselling rarely translates into portion-aware, consistent customisation at the point of sale.

Nutrition education gap

Typically, dietitians simplify meal planning with portion sizes, but clients often struggle to apply it in real contexts such as at restaurants, at groceries and at home. Serving-size labels are often vague and rarely show how they translate into day-to-day decisions, which makes "knowing" feel disconnected from "doing."

Restaurant operation in silo

Meanwhile, restaurants rarely provide accurate nutrition information. Customisation is common, but it is usually driven by operational or commercial incentives, not nutrition, so portions become inconsistent and nutrient intake becomes unpredictable. Operationally, they do depend on standard recipes, portion control, and modifications as they affect the cost.

Bridging the worlds

Nutrition guidance needs to be built into the ordering process, so clients can use it while choosing and customising a meal. A portion-aware POS can translate nutrition education into concrete portioning and ingredient choices, while keeping orders consistent and structured enough for the kitchen to execute and profitable enough to sustain.

Product concept

A menu planning and ordering system spans three touchpoints: a marketing landing page, a portion-aware ordering terminal, and a menu planner for dietitians:

Feature one

Marketing landing page

**Marketing the idea:** Conceptualising the novel idea with a concrete example first and foremost

Feature two

Portion-aware ordering terminal

**Menu customisation:** Customer orders a customised portion-controlled menu item

**Restaurant inventory:** Restaurant adds a standard recipe in the dashboard

Feature three

Menu planner

**Menu planning:** Dietician plans a menu while counselling assisted with artificial intelligence

Conclusion

This concept turns nutrition education into a real-world skill: customers learn by ordering with portion guidance embedded into the flow. By connecting the dietitian's logic to the terminal and kitchen workflow, "healthy eating" feels easy and practical: clearer choices, more consistent portions, and more measurable outcomes.
