MacroDiet is a macro and calorie tracking web app: you answer a short onboarding, it computes a daily calorie target and protein, fat and carb grams from the same formula as our macro calculator, and then you log food and body weight against those numbers. MacroDiet is live at macrodiet.fit and evolving; screens change as features ship, and anything marked "coming" below is not in the app yet.
What it does
The app has three jobs. It sets targets from your details using the v2 onboarding algorithm (Mifflin-St Jeor resting rate × an activity multiplier, minus or plus a rate-based deficit or surplus, then a protein / fat / carb split). It logs intake — food by search or barcode, one entry at a time, into an hourly timeline. And it records body weight, showing a scale-weight chart and a weight-trend page. The adaptive layer that the in-app tutorial cards describe — an expenditure estimate that updates from your logs, and a weekly check-in that adjusts targets — is coming; today the targets are the ones onboarding produced until you change them.
Step by step
- Open macrodiet.fit and tap "Get Started Free". You are sent to
/onboarding, which resumes wherever you left off if you come back in the same browser session. - About You (13 screens). Biological sex, date of birth, height, weight, recent weight trend, a body-fat estimate from silhouettes, a weight-history question, exercise frequency, daily activity, lifting and cardio experience, athletic identity, and an "Estimated Expenditure" reveal. What each one is for is in what MacroDiet's onboarding asks, and why.
- Your Goal (5 screens). Lose, maintain or gain; a target weight on a ruler; a rate of change (about 0.3, 0.5 or 0.75% of body weight a week); a calorie-target reveal; and the diet preferences — diet style, calorie floor, training during the program, weekly distribution and protein preference.
- Program (3 screens). A short "Building your program" animation, the macro program reveal (calories, protein, fat, carbs, and a Mon–Sun row), and a "How your program works" explainer.
- Get Started (5 screens). Feature highlights, an "Everything included" list, a "You're all set" screen, a plan-selection screen, and Create Account — email and password. Creating the account is the step that actually happens here: as of this writing the plan you tap is remembered on the screen only and no payment details are requested.
- First 30 Days, then the dashboard. After the account is created the app saves your onboarding answers to your profile and shows a four-milestone "First 30 Days" page (what is live on it). "Continue" opens the dashboard.
What the numbers mean
The dashboard on day one shows the targets onboarding produced, and nothing else yet. Worked with the example we use across these guides — a 30-year-old man, 180 cm, 85 kg, training four to six times a week, moderately active otherwise, goal "lose" at the moderate rate, balanced diet style, moderate protein — the app arrives at:
| Screen | Number shown | Where it comes from |
|---|---|---|
| Estimated Expenditure (About You reveal) | 2,837 kcal | BMR 1,830 × 1.55 |
| Your Calorie Target (Goal reveal) | 2,369 kcal average per day | 85 × 0.005 = 0.425 kg/wk → 0.425 × 7,700 / 7 ≈ 468 kcal below expenditure |
| Protein (Program reveal) | 153 g | 85 × (1.6 + 0.2) = 153 — the +0.2 g/kg is the deficit bump |
| Fat (Program reveal) | 68 g | 35% of the calories left after protein, ÷ 9 |
| Carbs (Program reveal) | 286 g | whatever calories remain, ÷ 4 |
The dashboard then arranges those into a hero carousel (a weekly nutrition grid, an Energy Balance chart of logged calories against expenditure or target, and today's calories, protein, fat and carbs), an Insights & Analytics row with the Expenditure and Weight Trend cards, a Habits row counting food-logging days and weigh-in days this week out of 7, a Body Metrics row (Scale Weight and Visual Body Fat, the midpoint of the range you picked), and a Nutrition row with today's four totals against their targets.
In plain terms: everything on the first dashboard is a formula output. The point of the next few weeks is to log enough real data that the numbers can be checked against it.
Gotchas
- The Strategy tab does nothing yet. It sits in the bottom bar with Dashboard, Food Log, Add and More, but it is a placeholder for the coming check-in flow.
- The "Steps" card is illustrative. The General section shows a steps card with sample bars; no step source is connected.
- Body fat is a picked range, not a measurement. The Visual Body Fat card shows the midpoint of the silhouette range you chose in onboarding, and it does not enter the calorie maths.
- "Customize Dashboard" and "Nutrition Data Manager" are listed but not interactive yet.
- Sessions are browser sessions. The access token lives in the tab's session storage; a fresh browser means logging in again.
The short version
Open macrodiet.fit, answer the 25 onboarding screens, create the account at the end, and you get a calorie target and a protein / fat / carb split from the v2 formula plus a dashboard to log against. Food Log and Dashboard are the two working tabs; the Strategy tab and the adaptive expenditure and check-in features it will hold are coming. The targets are a nutrition starting point to test with real logs, not a verdict. Educational overview only — not medical advice.
