The IIFYM diet is a simple approach to fat loss and muscle gain. But there’s one problem – how do you know what your macros should be?
Other IIFYM calculators are hard to use. Or they just spit out random macros in exchange for your email address. 😒
That’s why I made an easy and personalized IIFYM calculator. You’ll get goal-specific macros customized to your lifestyle and schedule.

What Is IIFYM?
In case you’re just starting out, IIFYM stands for If It Fits Your Macros. The idea is to target specific amounts of carbohydrates, protein, and fat each day.
By tracking macros you can manage your weight without overly restrictive dieting. Of course, nutrition is more complex than that. But IIFYM does have benefits.
IIFYM Benefits
The number one benefit of IIFYM is simplicity. All you really have to do is count macros.
But the real reason IIFYM works is calorie balance. That’s because each gram of carbs, fat, and protein has a set number of calories.
So by hitting your macros, you’re also controlling your calorie intake. Together, macros and calories account for about 60% of the nutrition puzzle.
However, if you stop there, you’re missing 40% of the pieces!
Limitations of IIFYM
While it can work, IIFYM is not a substitute for healthy food choices. In other words, you can’t eat pizza and donuts every day and expect to transform your body just because it fits your macros.
In order to optimize your results, you must also pay attention to the foods you eat. And be aware of the fact that when you eat matters.
How the IIFYM Calculator Works
Finding Your Calorie Target
It’s important to realize that your macros are dictated by your calorie target. And your calorie target depends on how many calories you burn.
To find out how many calories you burn, my IIFYM calculator helps you find your body composition and body type. Then calculates your base metabolic rate (BMR).
Next, you input your activity level and exercise habits. This leads us to your total daily energy expenditure (TDEE). A fancy way of saying how many calories you burn.
Finding Macros From Calories
All that’s left is to convert from calories to macros by finding your ideal macronutrient ratio.
Your macro ratio depends on your fitness goal. So, you choose whether you want to burn fat, build muscle, or do a little of both (recomposition).
Finally, we arrive at your ideal macro targets for transforming your body. These targets are expressed in terms of grams per day of each macronutrient.
After completing the IIFYM calculator, you’ll be taken to your results page. Here you’ll see your IIFYM targets (in grams) for days you workout as well as days you rest.
Plus, you have the option to sign up for a personalized IIFYM Diet Plan.
