You’re here because you want results. Whether it’s burning fat, building muscle, or finally taking control of your health and confidence, you’ve heard that tracking macros might be the missing piece. And guess what? You’re right.
Macros are more than a buzzword—they’re the blueprint for your success. By understanding and balancing the right combination of protein, carbs, and fats, you can eat the foods you love, fuel your body, and finally achieve the results that have been out of reach with traditional diets.
Not sure where to start? Don’t worry—we’ve got you covered. This guide will help you Start IIFYM and take the first steps toward transforming your lifestyle. There’s no better time to Start IIFYM than today!
This page is your guide to unlocking your best results. No confusion, no fluff—just a straightforward plan that works. Let’s dive in!
First, let’s start with the basics. You are at IIFYM.com—the birthplace of macros and the program that has helped over 53,000 people lose weight without the suffering of traditional diets.
My name is Anthony Collova, and I’m the founder of IIFYM.com and the creator of the world’s first Macro Calculator. The same calculator that went viral 14 years ago and revolutionized the way people approach weight loss.
Before the IIFYM Macro Calculator, people were stuck following any number of fad diets—confusing, restrictive, and full of misleading, contradictory advice.
But now, we know better. Now, we track macros and leave the dogma to the dinosaurs who refuse to keep up with modern science and common sense. With this guide, you’ll discover how to start IIFYM and unlock the power of macros to achieve real, lasting results. All thanks to that one little calculator I launched all those years ago, people around the world have been able to start IIFYM and transform their approach to weight loss.
Before we dive into why macros work, let’s look at why most diets fail—it’s probably what brought you here in the first place.
Most diets fail for one reason and one reason only: they’re not sustainable in the long term. They force you to overhaul your entire lifestyle, cut out foods you love, and follow overly restrictive rules just to make them work.
These diets might work temporarily, but let’s face it—they’re exhausting to maintain. The moment life happens (a birthday party, a vacation, or even a stressful week), they fall apart, leaving you frustrated and back at square one.
Take your pick:
No matter which one you choose, they all fail for the same reasons: they’re too restrictive, overly complicated, and impossible to stick to for the long haul.
Let’s talk about calories before you start IIFYM. Calories are the energy your body needs to function—everything from keeping your heart beating to powering your workouts.
But here’s the kicker: Not all calories are created equal. The balance of macronutrients—protein, carbs, and fats—within those calories determines how your body uses that energy.
Think of your body like a car:
If you give your body too much fuel (calories), it stores the extra as fat—like a gas tank that overflows into reserves. On the flip side, if you give your body too little fuel, it burns through your reserves (fat and muscle) to make it to the finish line.
The key is finding the perfect balance—enough fuel to keep you going, but not so much that you’re constantly storing excess. That’s where you Start IIFYM to take control of your energy and macros. By tracking macros (protein, carbs, and fats), you ensure your car runs smoothly, burns fat efficiently, and has the energy to perform at its best. Ready to Start IIFYM and fuel your journey the right way?
Here’s the simple science:
Where macros come in: If you just focus on calories alone, you might end up losing muscle or feeling sluggish. Macros make sure your calorie intake is optimized so your body burns fat, preserves (or builds) muscle, and functions at its best.
Unlike traditional diets that rely on gimmicks, restrictions, or one-size-fits-all plans, IIFYM works because it’s built on science, simplicity, and sustainability.
Here’s why it’s better than anything else out there:
Here’s the bottom line:
IIFYM works 100% of the time for 100% of the people who follow it, because it’s not based on gimmicks or fads. It’s based on giving your body what it needs, in the right amounts, while still allowing you the freedom to live your life.
Acronym:
Pronunciation: \ ˈī-ˈī-ˈef-ˈwī-ˈem \
Definition:
IIFYM, short for “If It Fits Your Macros,” is a flexible dieting method that focuses on tracking the three main macronutrients in your food: protein, carbohydrates, and fats. The goal is to hit your personalized macro targets each day, tailored to your fitness goals, body type, and lifestyle.
In order to start IIFYM, you simply track your macros using an app that counts calories and helps you stay within your macro targets.
Origin:
IIFYM began in the early 2000s on fitness forums, where frustrated dieters were searching for a way to lose weight without giving up their favorite foods. It started as a lighthearted response to questions like, “Can I eat a donut and still lose weight?” The answer? “Yes, if it fits your macros.”
What began as a simple response turned into a movement—combining the science of nutrition with the freedom to enjoy food guilt-free.
Example Sentence:
“Can I eat ice cream and still lose weight?”
“Sure, if it fits your macros (IIFYM).”
Unlike traditional diets that restrict certain foods, IIFYM flips the script. It allows you to eat the foods you love—pizza, burgers, ice cream—while still working toward your fitness goals. When you Start IIFYM, it’s not about what you can’t eat. It’s about balancing what you enjoy with what your body needs to burn fat, build muscle, and stay healthy.
Here’s how simple it is to start tracking your macros:
