MacroTDEE.com The Smarter Way to Understand Your Body’s Energy Needs
When it comes to fitness and nutrition, one of the biggest challenges people face is understanding how much their body actually needs — not just in calories, but in protein, carbs, and fats too. That’s exactly why I built MacroTDEE.com — a free, data-driven tool designed to help you take control of your nutrition and goals.
Most of us rely on rough guesses, outdated calculators, or the latest diet trend to make decisions about food and exercise. But your body deserves more precision than that. MacroTDEE.com was created to simplify complex nutrition science into something that’s accurate, fast, and easy to use — all without paywalls or subscriptions.
What Is MacroTDEE.com?
At its core, MacroTDEE.com is a macro, TDEE, and BMR calculator — built to help you understand three key metrics:
BMR (Basal Metabolic Rate) — the number of calories your body burns at rest.
TDEE (Total Daily Energy Expenditure) — how much energy you burn each day based on your activity level.
Macros (Macronutrient Breakdown) — how your daily calories should be split between protein, carbohydrates, and fats.
By combining these calculations, MacroTDEE gives you a personalised nutritional roadmap. Whether you’re aiming to lose fat, gain muscle, or maintain your current physique, it provides clear daily targets that can be used with your favourite meal-tracking apps or simply as a reference for mindful eating.
Why I Built It
I built MacroTDEE.com out of frustration.
Every calculator I tried was either outdated, behind a paywall, or filled with generic recommendations that didn’t match real-world goals. I wanted something simple, accurate, and completely free — with a clean design that loads instantly and works on both mobile and desktop.
More importantly, I wanted to create a platform that anyone could use, whether they’re an athlete, a coach, or just someone beginning their health journey.
Over time, MacroTDEE has also evolved into a content-driven hub, featuring articles about nutrition science, metabolism, and performance — designed to educate users, not just calculate numbers.
How It Works
The process is simple:
Enter your age, gender, height, and weight.
Select your activity level — from sedentary to very active.
Choose your goal — fat loss, maintenance, or muscle gain.
Click calculate — and you’ll instantly see your daily calorie target and recommended macro breakdown.
Behind the scenes, the calculator uses validated equations like the Mifflin-St Jeor and Katch-McArdle formulas — both trusted by sports scientists and nutritionists — to ensure results are reliable.
Who It’s For
MacroTDEE.com is for anyone who wants to make smarter, data-backed decisions about their health. That includes:
Gym-goers tracking progress and adjusting calories week to week.
Coaches and nutritionists needing a simple tool for client calculations.
Everyday users curious about what their real energy needs are.
Athletes optimising for recovery and performance.
Because it’s web-based and lightweight, MacroTDEE works just as well on your phone between workouts as it does on your laptop at home.
Beyond the Numbers
Knowing your macros and calorie needs is just the starting point. The real power of understanding TDEE and BMR is how it helps you make sustainable, long-term decisions about food and training.
It’s not about restriction — it’s about awareness.
When you know your numbers, you gain the freedom to experiment: adjusting protein intake to support muscle growth, increasing carbs before big training days, or lowering calories strategically for fat loss.
In the end, it’s not a diet — it’s a system. And MacroTDEE is the tool that helps you understand it.
The Bigger Picture
MacroTDEE.com is also part of a broader ecosystem of tools and projects I’m building through Core Haus — a collection of digital and physical ventures designed to improve how we interact with health, performance, and technology.
Each project focuses on bridging the gap between science and accessibility. MacroTDEE fits perfectly into that philosophy: a free, open platform designed to educate and empower anyone curious enough to learn more about their own biology.
