Software for nutritionists and diet coaches: the parts that actually save you time

Software for nutritionists and diet coaches: the parts that actually save you time

Nutrition coaching has a specific kind of admin drag. It's not one big task, it's a hundred small recalculations: this client's maintenance shifted, that one's training volume dropped, someone's travelling next week. Each one is five minutes of arithmetic and file-editing, and there are twenty clients.

Here's what Trainzilla does with that.

The maths, done once

The calculators are built in. Enter a client's stats and you get TDEE — BMR, total daily expenditure, and a recommended intake for their goal. Feed that into the macro calculator and you get a protein/carb/fat split by strategy: Standard 40/30/30, a Pro split at gram-per-kilo multipliers you set, or Keto. There's a 1-rep-max calculator too, for the strength side of hybrid clients.

No spreadsheet, no formula you half-remember. And when a client's numbers change, it's a recalculation, not a rebuild.

Diet plans from blueprints, not blank pages

You build meal plans from reusable dietary blueprints — a vegetarian lean-recomp template, a fat-loss template, a high-protein template — that you refine once and reuse across clients. Each carries its meal structure and calorie target, so a new client starts from your best work instead of nothing.

Ingredients are priced from a real nutrition database, so a plan's macros are computed rather than asserted. "Roughly 40g protein" becomes an actual number.

Check-ins built around food

Clients submit check-ins from the mobile app — weight, measurements, progress photos, and answers to the questions you set, which for a nutrition coach means adherence, hunger, energy, digestion, whatever you track. They land in one queue.

You schedule them weekly or fortnightly, make them recurring, and see who's pending at a glance. No more "did you send your check-in?" across three channels.

Where the AI earns its place

The recalculation problem is exactly what an assistant is good at. Point Trainzilla's AI at a client and it reads their profile, their recent check-ins and their current plan, then proposes the adjustment — "weight stalled two weeks at 1,900 kcal, adherence 90%, recommend dropping to 1,800 and holding protein" — with the reasoning attached. You approve it, it updates.

You can run that in the app, or connect it to Claude and ask in plain English: "Recalculate macros for [client] at 2g protein per kg for a 2,100 kcal cut, and draft the message I'd send."

It doesn't decide whether a client needs a diet break or a referral to a dietitian. It does the arithmetic faster than you can and drafts the obvious change, so you're editing instead of building.

Habits, for the behaviour half

Nutrition outcomes are behaviour, not just numbers. Habit tracking gives clients daily targets — a protein floor, a water target, a no-screens-at-dinner streak — and gives you a compliance percentage. That's the difference between "she says she's on plan" and knowing which day of the week she isn't.

Pricing

Free Launch is ₹0 forever — profile, one paid offer, invite link, marketplace listing. Fine for testing.

Coach Pro is ₹499/month: client app access, the nutrition tools, check-ins, progress tracking, payments, messaging, multiple offers, analytics.

A nutrition client in India typically pays ₹2,000–₹4,000/month. Coach Pro is roughly 15% of one client's fee. If it saves you an hour a week of recalculation, it's paid for itself several times over before the month is out.
