Fit Club: How to Track Macros

CATEGORIES: Health and Fitness

The most requested topic in our Fit Club and Fit Club instagram over the past months has been about counting macros.  If you’ve heard this term and wondered what the deal is, this post is for you!  I like to think of macro tracking as kind of advanced calorie counting.  Instead of focusing on the total number of calories you consume, you track the specific amount of protein, fat, and carbohydrates.  I started doing this about a year ago (on and off, let’s be honest- I eat a lot of baked goods and “start over on Monday” alllll the time) and it’s made such a huge impact for me.  I’ve lost about 20 pounds and put on a significant amount of muscle.  People ask me about counting macros all the time, but I don’t feel qualified to “teach” it.  So I’ve invited someone more than qualified to step in: my very knowledgeable friend Amber!  She’s not only a rising star on Instagram (@biceps.after.babies) but also a popular fitness instructor, Registered Nurse and Macro Coach.  In fact, one of YOU could actually win a free 6 WEEK coaching session with Amber.  Keep reading to the end to see how!  And if you have questions about anything in this post, make sure to leave a comment and Amber and I will be sure to answer everyone.   I’m going to turn it over to her, now!


Hi Everyone!  I’m Amber.  Every few years there seems to be a new diet trend that everyone jumps to try out. “You want to lose weight? Just eat low-fat!” “Or maybe high-fat, low carb?” “No, really you should just eat like a caveman.” “Or at least eat like a caveman for 30 days.” “But really, if you just cut out sugar, and don’t eat after 7pm, you will lose weight!”

What's the Secret to Weight LossThe novelty of these diet trends makes them tantalizing, but let me tell you a surprisingly simple secret – the way to lose weight is to be in a calorie deficit over time. That means, you need to consume fewer calories than you use. That’s it! That is the secret. You can lose weight eating low-fat, or Paleo, or Whole30, or no-sugar, or even nothing but Twinkies and Oreos. If you eat fewer calories than your body burns on any of those diets you will lose weight. Crazy, right? It’s true.


For all you skeptics, Mark Haub, professor of human nutrition at Kansas State University, decided to test this theory. For 10 weeks all he ate was processed Twinkies, Doritos, Oreos, and sugar cereals. The catch? He only ate those foods, but limited them so that he was still in a caloric deficit. The result? He lost 27 pounds. It is all about science – calories in versus calories out. If all you want to do is lose weight, calculate the number of calories you burn every day, eat 20% less calories and voila, you will lose weight regardless of the quality of food you are putting into your body.

So Why Track your Macros

If losing weight is all about calories in versus calories out why bother with tracking your macros? Because, while being in a caloric deficit will result in weight loss, the quality of weight loss is very different depending on what type of calories you eat.


Instead of just counting calories, knowing how much of each macro to eat results in more fat loss.  Because, while being in a caloric deficit will result in weight loss, the quality of weight loss is very different depending on what type of calories you eat.


What is a macro

Macro is an abbreviation of the word “macronutrient” which is any of the nutritional parts of food that are required in relatively large amounts for good heath: protein, carbohydrate, fat, and minerals such as calcium, zinc, iron, magnesium, and phosphorous. When you hear about someone “counting their macros,” though, it usually refers to tracking the amount of carbs, protein, and fat they consume – because those are the macronutrients that provide calories.


This approach to eating is also known as “flexible dieting” or “If It Fits Your Macros” or just simply “IIFYM.” IIFYM, is a method of dieting that revolves around you eating a set number grams of daily carb, protein, and fat each day. It is essentially a form of guided calorie counting.

How does Knowing

Most people say that they want to “lose weight,” but what they REALLY mean is they want to lose fat. Very few people actually have in their minds that they want to lose muscle or organ tissue or water weight. Those factors also make up weight on the scale, but that’s not what people want to get rid of. They want to decrease the amount of fat on their bodies while also maintaining as much lean muscle as possible. To do that, you need to have a balanced macronutrient intake.

Why is it important to pay attention to macro intake

If your macro intake isn’t balanced, the quality of your weight loss suffers. For example, if you aren’t eating enough protein during a calorie deficit, your body will break down muscles to use for energy. If you aren’t getting enough carbohydrates you can feel weak and unable to perform well during workouts, because carbs are fuel! Lastly, not getting enough fat into your diet can mess with your hormones and make your weight loss stall or make it more difficult for you to put on muscle, because fats increase your growth hormones.  While you can drop weight by counting calories, we aren’t just interested in losing weight.  We want to drop fat and we want a toned, healthy body.  For that, counting calories isn’t enough.  You need to count your macros.

You need to count your macros

One problem with many diets is that they encourage you to eat fewer calories by cutting out entire food groups. “Don’t eat gluten! Don’t eat sugar! Low carb is best! Only eat clean foods!” All of these diets will tell you that certain foods are off-limits. Some people are able to cut out dairy or grains or sugar 100% and never crave another donut for as long as they live. However, many more people – myself included – shudder at the thought of never being able to eat another bowl of ice cream, or slice of pizza, or fresh baked donut again.


In contrast, with IIFYM nothing is off-limits. There aren’t “good” and “bad” foods, it’s all just food. Food is made up of certain macronutrients and you have a daily goal of how many of each macronutrient to hit. So if you want ice cream for dessert you can have it! You just have to make sure that you don’t go over your daily allotment of carbs or fat. If you fit it into your macros then it’s not a cheat, it’s not bad – it fits! If it fits your macros you can eat it without any guilt or feeling like you “cheated” on your diet. This is a sustainable way of eating.


Now, don’t get me wrong, it’s really hard to eat processed junk food all day long and still fit your macros. Most of the food you consume is going to need to be traditionally healthy food like lean protein, fruits, and vegetables. 80-90% of the food I eat on a daily basis is nutrient dense “healthy” food. But the beauty of IIFYM is that you can easily make room for the treats that you want AND still hit your weight loss goal.  It’s a moderate, healthy way to approach eating.

Healthy Meal

You may be asking yourself, “Does tracking macros take up a lot of time and energy?”  The short answer is yes and no.  I won’t lie.  Because getting an accurate read on your macro intake requires weighing and logging everything you eat, the first couple of weeks can be fairly time intensive. However, after the first 2 weeks or so, it get much easier and faster.  I can log my whole day of eating within a matter of 5 minutes now.  So, no, it is not difficult to do once you get the hang of it.  And for me, once I started seeing the results, the counting and tracking was 100% worth it.

Worth It

If I have convinced you that IIFYM is a sensible and effective way to lose weight your next question should be,

How do I start

First purchase a food scale so you can weigh your food in grams. It’s really the only purchase you have to make, and it is required. Yes, you can scoop out ½ cup of oatmeal but sometimes that ½ scoop will be 35g and sometimes it may be 60g and that makes a big difference when you are tracking your macros. Weighing your food may seem like a pain at first, but I promise it becomes a habit and it really doesn’t take that much extra time.

Second, start logging what you eat normally. There are many apps to use for this, but the one that I know and love is MyFitnessPal. It’s free and you can use it on any phone or computer and it’s pretty intuitive to use. Try not to change the way you are eating and log your foods for 1 week. You aren’t trying to hit any macros or calories – just learning how to weigh and log foods and getting an idea of how many calories and what ratio of macros you are currently eating.

Last, calculate your macros. Now, there is a whole science behind setting macros so the easiest way to set your macros accurately is to hire a coach (like me!) to do it for you.  This is especially helpful if you don’t want to mess with finding the numbers for your body, you are not confident in your understanding of macros, or if you are unique in your goals, activity level, or weight loss history. But, if you want to do it for free (I get it! I am a budget-conscious momma myself!) I would start with using an online calculator. I find that the calculator on is a good place to start. The calculator will ask you about your age and height and exercise routine and will give you a macronutrient breakdown to follow. For many people this will be an accurate breakdown, but if you find that the numbers aren’t working, or if you need more one-on-one help in figuring out how to hit your goals, your best bet will be to hire a coach who can walk you through everything.

The bottom line for me is living a lifestyle that is maintainable for the long haul. IIFYM isn’t a crash diet. You don’t have to commit to never having another fresh baked cookie ever again.  

IIFYM isn't a crash diet

You can find moderation in eating AND lose fat at the same time. And for me, THAT’S the beauty of IIFYM.

  1. Thank you for this intoduction to macros. I’ve had a rough few months and been at a total loss of what to do. My weight continues to slowly climb and I’ve been totally freaked out by it. This feels like a much more approachable way to handle the ins and outs of a diet. Though also very terrifying for someone who has tried to eat healthy and exercise and I just keep failing. Any way to stay motivated until you start to see progress?

    1. That’s so frustrating, isn’t it?? Sometimes I have a hard time staying motivated myself. For me, I just have to continually remind myself of the end game and that it’s worth it to keep pressing on and stick with it because results are not often immediate! Totally just a mental thing, but sometimes I take something like a pair of pants I want to fit into or an older picture when I was super fit and put them somewhere I see often as a reminder of what I’m working for. Also, as cheesy as it sounds: one day at a time. This is a big one for me. I get frustrated when I feel like I have to be doing this forever and get overwhelmed thinking of how long it might take to reach a goal. So honestly, I work on things one day at a time. TODAY I am going to hit these macros. And then the next day. And then I try for a 7 day streak. Ya know? After that, look toward the next goal, but small baby steps are so much more attainable and keep me going!

    2. I think you will find that after you get over the initial hump of learning how to track your macros this style of eating will be very helpful for you because when weight loss stalls or when you gain weight you can very easily look at your macros and adjust them to keep fat loss going. When you are just eating “healthy” it’s hard to “eat healthier” when your weight loss isn’t occurring. But when you track macros now you have definite numbers that you can tweak until you find your sweet spot. And Sara has some GREAT ideas for motivation. Another thing I try to help my clients find out is their “WHY.” Why are they trying to lose fat? When you can really tease out your WHY and your motivation you can pull that out when times get hard.

    3. Kaitlan, one of the best ways to make progress towards your goals is by changing simple things like your kitchen environment. If you have snack foods on the counters, maybe put them away and put fresh fruit in line of sight. It’s important to create a support environment that helps you work towards you goals. If you are going to a social gathering and you do not know the food that will be served try eating something before you go. For may women getting enough protein in their diet can be a challenge. I recommend building all your meals around a protein source.

      Calories deficiency is the way you lose weight, but behavior is how you lose weight.

      You might benefit from working with a coach to help hold you accountable and guide you through learning the ropes with macro tracking. I find that when you work with a coach you have a higher rate of success then trying to learn something new without help.

  2. My current weight is what it was when I was in high school and ran track/cross country but my body shape is very different. After 3 kids (youngest is almost 4) my muffin top looks more like me when I am 5 months pregnant. I ran a half marathon about a month ago but I still look very pregnant. Will counting macros keeping my calories at a deficit cause me to loose weight? I’m really more interested in loosing fat and not weight. Do I want calories in = calories out?

    1. I am so glad that you understand the difference between weight loss and fat loss! And muffin tops are a COMMON complaint I hear from my clients. When you have a muffin top it is usually fat, which means that you do need fat loss to occur. For that to happen you need to be in a caloric deficit. What I would recommend is incorporating resistance training or weight lifting into your routine while you are in your caloric deficit. That will help you build muscle while you are losing fat so your weight will most likely not change much but the way your body looks will change as you lose fat and tighten everything up.

      1. Yes, the muffin top is absolutely fat. According to the myfitness app my macros are 50 carb, 30 fat, 20 protein. The IIFYM calculator gave me similar numbers. Is that right? I need more fat than protein?

        1. Is that per meal or total? Those numbers seem awfully low especially if you are a runner. I would recommend running your numbers again. Those as drastically incorrect. Your protein should be around .8 per body weight at least.

  3. Ok so question, when I’m in MFP it tends to give me a calorie goal that is too little. I noticed that I need to eat more for energy, but pick the foods well so I am not eating too many carbs. I love my bread! If I combine that with strength training and weights I am able to lose weight at a normal pace. How can I make sure I get the right macros and calorie goals for me since online calculators aren’t the best indicator necessarily for what you personally need. I guess my question is how do I find out what the best goals are for me?

    1. I calculated my macros on the website she listed above. It gave me a calorie number that was higher than MFP. So I just went into MFP and manually enter then calories given from IIFIYM. Then adjusted the macros to fit my goals. Worked out nicely.

    2. There is definitely some trial and error involved. Online calculators only take you so far, sometimes what you really need is to mess around with the macros to find the best ratio for you. So I would try setting your calories in MFP to what you feel like is an appropriate level for you and then adjust your macro percentages to find a good spot for you and your body.

  4. I’ve been counting calories on My Fitness Pal for a few years now. Is this the program you recommend as a macro counter? If so, is it easier to track if you upgrade to premium? Or do you just track them from the nutrients option on you daily log?

    1. Yes, I use My Fitness Pal and just keep an eye on the numbers in the nutrients option as you mentioned. MFP doesn’t let you always set the numbers EXACTLY, which was frustrating to me, so I actually did upgrade and pay the monthly fee eventually but it is totally not necessary. Amber also found a hack you can use with a 3rd party extension that is totally free. I was just a little worried about spyware so I just upgraded to MFP. But you can scroll through her instagram (or google!) to find it!

    2. I love MFP and you definitely don’t need to pay for the upgraded version. The hack that I posted about actually has been not working lately – I think MFP caught whiff of it and shut it down. 🙁 But you can still set your macros pretty close by hitting goals, setting your calories and then adjusting the percentages. If you want to pay for the upgrade that’s an easy way to be able to set your macro goals to the gram. But either way to see the macros you have eaten for the day you can either go to the “nutrition” tab or if you are on your phone just turn your phone sideways and scroll to the bottom and your macros for the day show up there.

  5. i have been counting macros for a few months and I LOVE IT! Now my question is, how would I continue if I get pregnant? I am planning on this in the next few months and would love to retain my results that I’ve had so far! How does it work with nursing too?

    1. I’m obviously not a doctor (stress on the obviously), but honestly you don’t need a massive calorie adjustment when pregnant. As long as you are active and healthy, you can continue exercising and tracking your macros. I would just be careful of ever cutting too low in any one area. It’s not a time to try and lose pounds necessarily, but tracking macros is a great way to keep a healthy diet maintained and continue to build muscle (which you will need to tote the belly around!)

    2. I echo what Sara said. You can very safely count macros while your pregnant – in fact the emphasis on protein is GREAT for pregnant moms who tend to not get enough protein. The difference is your goals change and instead of trying to lose fat you are trying to experience healthy weight gain. But tracking your macros and adjusting them based on your weight gain can really help you not gain too much fat during your pregnancy which is good for your body and for your baby.

    1. I’ve never tracked macros while nursing. I started right after I stopped nursing my last baby. But with all my babies, I found I could find the “sweet spot” in a calorie range where my milk supply was staying healthy and I also could lose weight and then I tried to just stick in that area. I feel like everyone is different when nursing and you kind of have to try adjusting things until everyone is happy (mom, baby, and tummy! haha)

    2. This is a question I get asked a lot, and obviously it is different for every woman. But I coach a lot of nursing moms and I have found that with a modest caloric deficit of 20% from their TDEE (total daily energy expenditure) most moms still have no problem with milk production. If the baby is really little (like 6 weeks – 4 months old) I will sometimes add in 200 calories, but most times I don’t have problems with women losing their milk supply. High protein is REALLY great for moms and especially for nursing moms, so I find that with the extra protein the lower calories don’t seem to impact milk supply.

  6. Hello ! as a blogger (a french one) I find that article brilliant: well written, easy to understand (and it’s always hard to simplify nutrition, I know it) and full of great insights. I was wondering if you would mind if I translated it in french and reposting it (OBVIOUSLY linking to your website, of course). let me know if you would agree 😀 (i’d rather ask, cause I don’t want to steal content from you, that would be disrespectful.)

  7. Okay so what about if you’re cooking a meal like casserole or a pasta dish or something? Or do you just only eat one ingredient things? Adding up all the ingredients and then guessing a serving size seems tedious and inaccurate

    1. In MFP you can upload the recipe and the servings and it will calculate it for you. Then it saves the recipe so you can just click on it next time you make it!

    2. Amber has a post about this on her Instagram. It is super helpful! She explains how you log each weighed ingredient into MFP and then you enter your recipe and put the amount the whole casserole/dish weighed in grams as the number of servings and then you weigh your serving amount in grams…

      1. Yes! Just like Chrissy said! If it still doesn’t make sense to you shoot me an email and I can walk you through it. Let’s pretend you made a cake. You would weigh the pan before you cooked it, then weigh the cake and pan after you cooked it, and subtract out the weight of the pan so you know how much it weighs. Then you enter your recipe into MFP and when it asks for the number of servings the recipe makes you put the weight of the cake in grams (ie 3,000g). Then when you log it in your diary you weigh out your slice – let’s say it weighed 200 grams, then you would log it as 200 servings of cake.

    3. You definitely don’t guess on the serving size, you just have to do the math. I will admit it can be rather tedious, so you do have to put the time into doing it! Like someone else mentioned, Amber has shared a great tip about calculating a whole recipe. I’ll have her come share it because I just tried to write it out several times and deleted because I’m not making sense, haha!
