Coaching platforms keep shipping the same nutrition feature. The newest release notes add food search and drag-and-drop meal plans, and the release before that added photo logging of every meal. It is the shape of the calorie tracker a client already has on their phone. Logging what you ate records the past. A meal plan built from targets tells them what to eat next, and that plan is the part worth handing over.
The tracker makes the client do the work
A food diary hands your client an admin job: weigh the food, log it, repeat, three times a day. The plan you built becomes a bar chart they fill in rather than a set of meals they follow. The week's review then reads like a compliance report on a diary you never asked to read.
A diary records what happened. A meal plan tells you what to eat next.
A record, or a plan for what is next
The difference is which job the client is doing. Logging happens after the meal and asks for effort every single day. Following a plan happens at the shop and at the fridge, from a sheet pinned where they will see it. The plan carries the targets and the recipes, so the client can put the phone down and still eat well.
Where the numbers come from
The targets come from a formula. Mifflin-St Jeor works from height, weight, age and activity, and when a body-fat figure is in the records, the engine switches to Katch-McArdle and uses lean mass instead. No body-fat number? Three tape measurements give an estimate, and it is labelled as an estimate everywhere it appears, because a tape figure carries roughly three to four per cent of uncertainty.
The point of the formulas is that the client can see where the number came from. The target on the sheet comes from the client's own numbers. When they ask why, you can show them the inputs and the formula.
What the client actually receives
From those targets the app builds a plan from a library of 557 recipes, filtered against the client's allergies and intolerances before any meal is chosen. The client receives three branded documents: a targets sheet sized for a phone, a three-day meal plan, and recipe cards behind a combined shopping list. Your name, your colours, your logo. They print on paper and they read on a phone.
When logging still earns its place
Some clients should log. Body-composition and stage-prep clients have signed up for that level of detail, and their numbers feed the review. The plan comes first either way, and the diary is the exception a client opts into.
The coaching is deciding what a client eats. Build the plan from their own numbers, filter it to what they can actually eat, and hand them something to follow.
