Nutrition coaching software for coaches who prescribe, not guess

Nutrition coaching software splits into two camps. Consumer trackers give the client a food diary and give the coach nothing. Coaching platforms bolt on a static calorie target and call it nutrition. Neither carries the actual work: prescribing targets with structure, adjusting them as the body adapts, and seeing compliance without spreadsheet archaeology.

Colossus treats nutrition as a first-class coaching surface, prescribed with the same precision as training.

Targets with structure

Prescribe different macros for training days, rest days, and weekend refeeds, and stack further adjustments on top. Athletes track calories, macros, fibre, and ten micronutrients, and see a one-tap breakdown of every modifier that landed on today's target, so the number is never a mystery to the person hitting it.

Meal plans and a recipe engine

Author meal plans by day or by template, with a recipe builder backed by a platform-curated library of public-domain recipes. Logging runs against a 2.5-million-item food database with barcode scanning, so compliance does not depend on the client hand-typing chicken breast every night.

Adaptive targets, grounded in logged data

The adaptive engine estimates a client's real maintenance from what they actually logged eating against their weight trend, and proposes a weekly adjustment from evidence instead of a formula guess. Client-set goals apply it automatically; on coach-set goals the estimate waits for your approval, so the coach stays in charge of the prescription. Calorie floors and cited safety warnings are built into the math and are never paywalled.

Compliance you can coach from

A single weekly compliance score gives coach and athlete one shared number for how the week landed against the plan, alongside habit streaks and check-in trends. Supplement schedules live on the same client record, so the whole protocol sits in one place.

Frequently asked questions

How big is the food database?

2.5 million items with barcode scanning, plus a recipe builder and a curated public-domain recipe library.

What does adaptive mean in practice?

The engine compares logged intake against the client's weight trend to estimate their real maintenance, then proposes a weekly target adjustment. You approve changes on coach-set goals; client-set goals apply them automatically. Safety floors and cited warnings are built in.

Can I set different macros for training and rest days?

Yes. Day-type targets for training days, rest days, and refeeds are native, and the athlete sees a breakdown of every modifier on today's number.

Does nutrition coaching require a specific tier?

Nutrition tracking, meal plans, day-type targets, and the adaptive engine ship across tiers, from R499 a month with a 30-day money-back guarantee.
