featureCustom Calorie & Macro Goals
Set Your Own Calorie and Macro Goals — Gram by Gram
Choose your own daily calorie target and exact gram values for protein, fats, and carbohydrates — or start from a guided estimate. Your plan, your numbers.
Most calorie apps hand you a computed target and expect you to live with it. SlimAI Calorie Tracker works the other way: you can set your own daily calorie goal and your own gram-level targets for protein, fats, and carbohydrates, so the app tracks against your plan instead of replacing it.
Custom Calorie & Macro Goals is built for people who already know their numbers — from a coach, a nutritionist, or their own experience — and for anyone who wants specific control over their intake. Eat smarter, not stricter.

Why a Fixed Computed Target Gets in the Way
Formula-based calorie targets work well as a starting point, but they frustrate people with specific goals. An athlete in a cutting phase, a lifter following a coach-prescribed macro split, or someone applying a nutritionist’s plan already has numbers to hit — and an app that insists on its own computed target forces them to track around the tool instead of with it.
Many tracking apps do offer some level of custom goals, though gram-level macro targets are often reserved for paid tiers, per public feature descriptions as of July 2026. Free tiers frequently limit macro goals to percentage splits, which cannot express a plan like “180 grams of protein, whatever the percentages work out to.”
SlimAI Calorie Tracker treats your targets as yours. You can set the exact calorie and gram values your plan calls for, and the same AI logging flow — scanning, portion guidance, and macro tracking — scores every meal against those numbers.
How Custom Goals Work in SlimAI Calorie Tracker
SlimAI gives you full manual control over your daily targets, with a guided option available whenever you want a reference point.
Set your own daily calorie goal
Enter the daily calorie target you want to track against, so your dashboard measures the day against your plan rather than a number the app chose for you.
Set exact gram values for protein, fats, and carbohydrates
Define each macro target in grams — not just percentages — so a prescribed split like a specific protein number is tracked exactly as written.
Use the guided estimate when you want it
SlimAI can estimate a personalized target from your goals and profile, so you have a starting point if you do not have prescribed numbers. The estimate is a suggestion, never a lock.
Change your targets anytime
Plans change between training phases, seasons, and check-ins. You can update your calorie and macro goals whenever your plan does, so the app keeps up instead of holding you back.

Who Custom Calorie & Macro Goals Is For
Custom goals matter most when your numbers come from somewhere specific. SlimAI does not restrict how you set your targets.
Athletes with prescribed macro splits
Track a cutting, bulking, or performance plan with the exact gram targets it calls for, so your logging matches your programming.
People training under a gym professional
If your trainer or instructor set your calories and macros, enter those numbers directly, so every logged meal is scored against the plan you are actually following.
People applying a nutritionist’s advice
Turn a nutritionist’s written targets into daily tracking, so appointments and everyday meals stay connected by the same numbers.
Anyone who wants very specific control
You do not need a coach to want exact numbers. SlimAI doesn’t restrict how you set your targets, so your goal can be as specific as you want it to be.
Your Goals, Connected to Every Logged Meal
Custom goals only matter if the rest of the app respects them — and in SlimAI Calorie Tracker, it does.
Every meal you log — by camera scan, voice, barcode, or text — is scored against your numbers, not a generic template. The calorie dashboard shows your remaining budget against the calorie goal you set, and the macro tracker shows protein, carbohydrate, and fat progress against your gram targets.
The food health score and real-time portion guidance use the same targets, so when SlimAI suggests how much of a plate fits your day, the suggestion is computed against your plan. Progress and Insights track the same numbers over time, so the story your history tells is the story of your goals.
When the Number Stops Working
Every calorie target has a shelf life. The number computed for the body you had at setup is not the number your body needs after you have lost weight, and nothing about a fixed goal tells you when that moment arrived.
SlimAI watches for it. When your smoothed weight trend has been flat for at least 14 days and your logging over that period has been solid, it names the plateau and proposes one small change — a single conservative step down in calories, or 2,000 more steps a day. It proposes; it never applies. You confirm, and you can undo it.
If your logging has been patchy, SlimAI does not touch your target at all — a stall with unreliable data is a data problem, not a plateau. And an accepted change writes to exactly the same fields this custom goal editor writes to, so your own numbers always override.
The same is true when you change something yourself. Update your weight, goal, pace, or activity level and SlimAI recomputes the calculated plan — but your custom split is not discarded and not left stale. It is read back as percentages and re-applied to the new calorie total, so a 40/30/30 stays 40/30/30 at the new number.
A Note on Medical Conditions
SlimAI Calorie Tracker is a tracking tool, not a source of medical or dietary advice, and it does not promise outcomes.
If you are managing a medical condition, are pregnant, or have a history of disordered eating, consult a doctor or registered dietitian before setting calorie or macro targets. Custom goals work best when the numbers you enter come from guidance that fits your health — SlimAI’s job is to track them faithfully, not to prescribe them.
FAQ
Still Wondering About SlimAI
Can I set my own protein, carb, and fat targets in grams?
Can I set my own protein, carb, and fat targets in grams?Yes. SlimAI Calorie Tracker lets you set exact gram values for protein, fats, and carbohydrates, alongside your own daily calorie goal. You are not limited to percentage splits, so a plan written in grams can be tracked exactly as written.
Is SlimAI good for athletes?
Is SlimAI good for athletes?Yes. Athletes with prescribed macro splits can enter their exact calorie and gram targets, and every logged meal is scored against those numbers. Portion guidance, the macro tracker, and progress views all use your targets, so training-phase plans stay intact.
Can I use SlimAI with my nutritionist’s plan?
Can I use SlimAI with my nutritionist’s plan?Yes. If a nutritionist gave you calorie and macro targets, you can enter them directly and SlimAI tracks every meal against them. For medical conditions, keep working with your nutritionist or doctor on the numbers themselves — SlimAI tracks the plan, it does not prescribe one.
Does SlimAI force me to use its calculated calorie goal?
Does SlimAI force me to use its calculated calorie goal?No. SlimAI can suggest a personalized estimate from your goals and profile, but it never locks you into it. You can override the estimate with your own calorie and gram-level macro targets at any time, and change them whenever your plan changes.
Can I change my calorie and macro goals later?
Can I change my calorie and macro goals later?Yes. You can update your daily calorie target and your gram values for protein, fats, and carbohydrates anytime — between training phases, after a coaching check-in, or whenever your plan changes. Logging keeps scoring against your current numbers.
How is this different from custom goals in other apps?
How is this different from custom goals in other apps?Many apps offer some custom goals, and some reserve gram-level macro targets for paid tiers, per public feature descriptions as of July 2026. SlimAI combines gram-level control with real-time portion suggestions and over-goal warnings in the same AI logging flow, so your custom numbers shape guidance during the meal, not just a report afterward.
