Revisiting IIFYM

Last year, I wrote a post on the If It Fits Your Macros (IIFYM) diet and what my thoughts were on it.

During that time, I think IIFYM was still gaining traction in the fitness community. Now, I see it everywhere. Just search #IIFYM on Instagram and you’ll come up with hundreds of posts.

Initially, I was not a fan of this. As I mentioned in my original post, an article that I had read on IIFYM stated that

How can a burger from McDonalds be equivalent to a meal of chicken, brown rice and cashews? It’s quite simple, your body does not recognize whether the food your eating is ‘clean’ or ‘junk’. It will only recognize food’s for it’s nutrients, such as proteins, fats or carbohydrates.


Hmm…I don’t buy it. But that’s just me. I don’t see how eating something from McDonald’s can be the same thing as chicken and vegetables. I get that they may have the same macronutrients, but what about the preservatives and chemicals in that burger?

But at the same time, I do like the IIFYM way of thinking. While I don’t think fast food and actual food are comparable, I like the premise behind this way of eating.

If you’re not familiar with IIFYM, basically instead of tracking calories you track your macronutrients (grams of protein, carbs, fat and fiber). You can figure out how many calories and grams of each of those things you need using this IIFYM calculator.

The reason I like IIFYM is because it allows you do be more flexible with your nutrition. Yes, we all know we should “eat clean” but sometimes you want to splurge a little. You want to go out to dinner with friends, or indulge in a bit of ice cream. IIFYM allows you do to that because you can simply include those into your daily macro counts.

I don’t agree with IIFYM in terms of “Eat whatever you want just count your macros” but it is a more flexible approach to nutrition than other diets such as paleo or just calorie counting. Plus, if you just count calories, you’re not making sure that you’re actually getting enough protein, carbs and fat in one day. My main goal is to eat as many whole foods as possible, but indulge when I want to and not feel guilty.

What do you think of IIFYM? Have you tried it?

  1. I agree with the concept. Like you said, there is a limit, fast food is not completely comparable to a whole food sandwich. However, I do like that it allows flexibility and doesn’t just focus on calories, making for a more balanced approach overall.
