# How an In-App Coach Knows Today's Leftover Calories

> A generic chatbot says eat less. Option 1 is Khatwa: photograph dinner, then ask what is left from the day you already logged.

The problem is a chatbot that never saw lunch. "Eat in a deficit" and "sleep eight hours" are not a plan for 410 calories left at 7pm. Option 1 is Khatwa. Photograph the meal. The coach answers from today's leftover calories, your goal, and the streak. It is not a neural engine and it is not mathematically precise. It is a coach that has the log.

Advice starts from the plate you just logged.

## What it can and cannot do

It can use leftover energy to suggest dinner. It can sit next to a guided home or gym program. It cannot replace a clinician. It cannot weigh oil the camera missed. You correct that. Then you ask again.

### Ask from today's number
