IIFYM (If It Fits Your Macros)

IIFYM, also known as If It Fits Your Macros, was created by fitness enthusiast Anthony Collova.

After becoming super frustrated with traditional dieting, Collova set out to create something that would allow him to eat the foods he loved and still lose weight.

Instead of focusing on calories, IIFYM is all about tracking your macronutrients.

The main macronutrients you will track are protein, fats, and carbohydrates.

Since you won’t be focusing on calories, this type of dieting allows you to have more flexibility as far as what you eat.

The Pros and Cons of IIFYM (If It Fits Your Macros)

The Pros Of IIFYM

There are many benefits to following the IIFYM way of eating. Here are just a few.

You Can Eat Whatever You Want

When you are following this type of eating plan you are free to eat whatever you want.

There are no foods that are off limits.

As long as the foods fit into your macros you can eat them.

Allowing you to eat all foods makes this process a lot more enjoyable.

You Will Lose Weight

At the time of writing there is quite a bit of conflicting information as to whether or not If It Fits Your Macros can help you lose weight.

However, being that this type of diet is high in protein, your metabolism will get a boost.

You should also know that IIFYM does require you cut your calories by up to 25%.

And as you know, anytime you reduce calories you will lose weight.

This type of flexible dieting also requires you track everything.

Tracking your food has been proven to help people lose weight.

You Will Learn A Lot About Food

We believe this type of diet is one of the most educational diets you could ever go on.

When you are tracking your foods you start to learn a lot about the macronutrient composition of each food.

You will start to realize that though a snickers bar and 5.5 ounces of salmon have roughly the same number of calories, their macronutrient profiles are very different.

If you have never tracked your food before this will prove to be an eye opening experience.

It Is Easier To Stick To

IIFYM is centered around flexibility.

And as already stated, there are no limits on what you can eat.

Because of this flexibility sticking with this type of plan is a lot easier.

The best part is this type of plan will work with any eating style.

For example, it doesn’t matter if you are vegan, vegetarian, or paleo, If It Fits Your Macros will work for you.

The Cons Of IIFYM

As with all things there are a few downsides to this type of plan you should be aware of.

It Doesn’t Consider Health Conditions

As with all diets, IIFYM is not for everyone.

If you have a health condition that requires you eat a special diet, then IIFYM is not for you.

While you may be able to make some adjustments, we believe its best to stick with whatever diet your doctor puts you on.

It Focuses Only On Macronutrients

Being that you only track macronutrients on this eating plan, that means you will more than likely be lacking in micronutrients.

Micronutrients are the vitamins and minerals you get from foods such as fruits and vegetables.

While If It Fits Your Macros does encourage you to eat a healthy diet, you don’t track micronutrients so you never know if you are getting enough.

And being that most fad diets do not provide you with an adequate amount of vitamins and minerals, chances are most people will come up short when following IIFYM.

If you don’t eat a lot of vegetables consider taking a multi-vitamin mineral supplement on a regular basis.

Its Still a Diet

Yes IIFYM is flexible. But that doesn’t mean its not a diet.

It is still a diet and you will need to follow it if you want results.

Research shows that most diets aren’t sustainable and therefore do not work over the long term.

However, based on our experience people get amazing results with If It Fits Your Macros.

Just know that you will need to make healthy eating a lifestyle if you want the results to last.


If your goal is to lose weight without feeling deprived, If It Fits Your Macros can help.

Just know that it will require you track every piece of food you put in your mouth.

If you do not track your macronutrients you will not get the results you are after.

This type of eating plan is also great for those who are trying to build muscle mass.

Again, you can eat whatever you want as long as it fits your macronutrients.
