How to calculate your macros for fat loss

The foods we eat are made up of three macros (macronutrients). These are carbohydrates (carbs), protein, and fat.

Chicken is high in protein but has no carbs; rice is high in carbs but has very little fat or protein.

The three macronutrients provide the body with energy and raw materials for growth and repair.

By calculating the appropriate daily calorie amount for you, we can then break this down into the best macronutrient ratios to achieve weight loss.

The calculator is based on sound science, combined with data from years of coaching hundreds of successful clients.

What is a good macro ratio for fat loss or muscle gain?

Your macros should be based on your Total Daily Energy Expenditure (TDEE) and your goals.

The calculator defaults at the best macro ratio proven to work for most people.

This ratio is:

  • 30% fat
  • Protein is 0.65 grams per pound of body weight,
  • The remainder is carbs.

Depending on your goal, this will be either a calorie deficit or a surplus.

You can go further and make more adjustments: Perhaps you’re an extreme endomorph and do better with fewer carbs. Or perhaps you have one kidney and need to eat less protein.

You can fine-tune your results for you with a bit of math. See how to change your macros here.

What is a good protein ratio?

Rather than a percentage, proteins are based on your body weight.

Our calculator has three settings:

  • Moderate adjusts the ratio to 0.65 grams per pound of body weight.
    This is appropriate for sedentary individuals or people with higher body fat percentages.
  • High is for active people with moderate strength training and an average body fat percentage.
  • Maximum will set the ratio to 1 gram per pound.
    This amount is good for bodybuilding and gaining muscle mass. You must be doing intense training.

Find out how to fine-tune your protein ratios when counting macros

Fat macro ratio

Set fat at 30% of daily energy expenditure.

Most people do very well with this amount of fat. See more about choosing the best macro fats. Because of high-fat diets like keto, many people are now eating more fat than they need to.

Carbohydrate macro ratio

Once you’ve calculated protein and fat, the remainder of your daily calories should be from carbohydrates.

Carbs fuel your body and workouts and are the body’s preferred energy source.

If you are coming from a low-carb background, this may seem high. However, according to respected nutritional research, this is a moderate amount of carbs.

If you are eating according to your TDEE, the notion that carbs cause weight gain or stop fat loss is incorrect.

Using as a Calorie Deficit Calculator

As a weight loss calculator, this tool establishes a safe calorie deficit only.

The Lose option puts you in a 20% calorie deficit, promoting safe, steady weight loss.

The best macro ratio for body recomposition

If you want to recompose your body (lose fat and gain muscle simultaneously), then use the body recomposition calculator.

Macro ratio for maintenance

The Maintain button shows you the macro levels to maintain your current weight.

This is great if you have lost weight and don’t want to gain it back.

Macro ratio for muscle gain

The Gain button puts you in a 20% calorie surplus.

The macro breakdown is designed to build muscle fast in conjunction and must be combined with a comprehensive weight training program.

It can also be used by people who are underweight.

TIP: Try starting with the maintenance goal and then gradually increase calories from there if you want lean muscle gains.

Calculating macros using your body fat percentage

The calculator uses your body weight to determine calories and macros.

However, you can obtain superior results by using your body fat percentage. The calculator allows you to choose which method; Normal for body weight, Lean Mass for fat percentage.

When to choose the Lean Mass Formula

If you are lean (have a low body fat percentage), choose the Lean Mass formula, and enter your body fat %.

If you are classified as obese and have a lot of weight to lose, the lean mass formula is superior. You can read more about macro counting and obesity.

Help? Calculate your ideal body weight or get an assessment of your body fat percentage.

Why the difference? Muscle cells burn more calories than fat cells, so the more accurately we measure this, the better your results will be.

How to calculate macros per meal

Once you’ve calculated your daily macros in the calculator, you can break this down into meals.

Choose from 2 to 6 meals per day to see the macro ratio you can track for each meal. For some people, this is easier, but for others, this is too much detail.

Do what works for you.

Meal Plans

See a 5-day macro-based meal plan. It includes three meals and two snacks per day.

Macro calculator activity level settings

A higher activity level means a higher daily calorie goal.

For example – if you maintain your weight at 2,000 calories per day, adding vigorous daily exercise means you need more calories to maintain your weight.

If you are sedentary and trying to lose weight, adding exercise will increase your daily calorie goal.

The idea seems counter-intuitive, but more energy is required to fuel your workouts. More workouts lead to increasing metabolism; therefore, more fat is burned!

Undereating is one of the leading causes of the weight loss plateau.

So many of our clients previously “hit the wall” with dieting. They would continually reduce calories, stop losing fat and gain weight when they eat a little more.

Macro counting defeats this by prescribing the right food and calorie levels.

Which activity level do I choose?

  • Sedentary: Just regular everyday activity like a bit of walking, a couple of flights of stairs, eating, etc.
  • Light: Any activity that burns an additional 200-400 calories (females) or 250-500 calories (males) over your sedentary amount.
  • Moderate: Any activity that burns an additional 400-650 calories (females) or 500-800 calories (males) more than your sedentary amount.
  • Extreme: Any activity that burns more than 650 calories (females) or more than 800 calories (males) in addition to your sedentary amount.

Other options for determining your calorie burn

Why should I eat more when I exercise more?

High physical activity not fueled with enough calories will lead to muscle catabolism (breakdown of muscle fiber).

This lack of nutrition could stall your weight loss, so eat up if you love to exercise!

I’ve got my macros – now what?

Once you’ve identified your target daily macros, you must determine the macros in all the foods you eat.

By tracking them daily, you can reach your recommended macro targets that encourage fat loss, muscle gain, or whatever your goal may be.

You can learn more about the macro counting system and the flexible dieting philosophy. Many people use an app like Myfitnesspal to track macros.

For more specifics on what to eat – see a sample macro meal plan or a list of macros for familiar foods.

I've helped 14,000+ people lose thousands of pounds by tracking their macros.

    Hi — Im in a womens IIFYM facebook and notice women eating higher macros than me. Ive been using a PT who has brought my macros down these last five months to what im feeling isnt correct now. Some days I want to chew an arm off Im so hungry, and he tells me to drink coffee.

    Im 5’6 inches and weigh 161 lbs. Im 45. Im at
    Carbs: 120
    Fat 35
    Protein 150

    And been stalled at 161 for about 5 weeks now. So, hes drawing my protein macro down to

    Carbs 120
    Fat 35
    Protein140

    I was on Jamie Easons 12-wk and now on Jom Stoppanis 6 week shred + 30 min cardio a day in addition to program requirements. I take a rest day every week. I am at a desk job.

    I ran my numbers here on your site and my macros would be much higher. I pay quite a bit for my PT and with that I think he should “know” how to calculate accurately but after calculating here and talking with other IIFYM women – Im really concerned that my body is mad at me and holding onto the weight because Im not giving it what it needs. Help?

    Thank you!

      Hi Sandrico, I hate when PT’s think the solution is to eat less. Absolutely incorrect. You just paid this person to slow down your metabolism. You’ve got to eat enough to support your metabolism and exercise. You havn’t been doing this and it has resulted in a calorie deficit that’s unhealthy. Please see my article here for more explanation. https://healthyeater.com/eat-to-lose-weight

        Hey Ted — I nixed my PT and signed up with you all for two months of ‘coaching’. Looking forward to getting on my plan and working my goals (hopefully without chewing off anyone’s arms)! Also looking forward to learning some important details and information you’ll provide. Thanks for your response and acknowledging my concerns with my current macros!

    This is so helpful thanks so much. Im just curious, what site (app)hould i use to track my macros? Im currently using My fitness pal but its all in percentage (my protein intake is at 32% but mfp has the options at 30% and 35 so the numbers will always be off. Is there another app thats more accurate?

    Hi,
    Thank you so much for your post. It is very helpful! As with most, I am a little hesitant with the calculations I got from your calculator as is has put me at 1676 calories. I am 40 years old and I weigh 137. I am looking to lose about 10 pounds while toning. I workout about 4-5 days a week with weights at HIIT. Can you tell me if this is accurate? Also, what are your thoughts on carb cycling? Do you think it’s needed in my case? Any help will be greatly appreciated!

    Hi,
    I am new to IIFYM and doing my research and testing the water.
    I am 31 yrs, 5’6, 128lb and want to loose body fat and gain lean muscle.
    I typically workout 4-5 times a week, 3 days of weight training and 2 days with classes (kickbox cardio and a whole body works). I have an office/desk job.
    In the calculator what do i use for my activity level?
    Thanks

    Thanks for this! I am a bit concerned my carbs may be too high? I got 193 grams. I am 21, 5ft 2 127 pounds, workout 6 times a week and am sedentary most of the day. I am worried that the carbs may be too high that my body won’t burn it but rather store it as fat?

    • Ted

      Hi Dana, Your body won’t convert carbs as fat unless you eat too many at once or eat them in excess of your TDEE. Carbs fuel your body and workouts and do not cause weight gain when consumed in relation to your TDEE.

        Awesome thanks so much. Now if I’m not sure how much I can lose what do I order? My goal isn’t necessarily the number on the scale even though who doesn’t love that to go down but I will be doing spin bootcamp and strength training and I want to see changes and build lean muscle.

          It looks like based on an estimation of an ideal body weight for a woman of your height, you would have less than 10 pounds to lose. Go with the muscle edition as this seems to better fit your goals. Also, if you go with the premium version, I can answer questions you have in our members only forum and you get a couple nice bonuses as well. Thanks for considering and all the best.

    Hi Ted,

    I’ve started using your my macro+ app and am enjoying it. You talk about active and non-active macro days. I’m 5’5″ and 180# female, recently lost 30 pounds with general diet and exercise changes but have hit a plateau. What do you suggest for macros for exercise days vs non-exercise days? Thanks!

    Reply
    • Ted

      Hi Stephanie, Nice work! For non-exercise days use the sedentary setting. For exercise days use an exercise setting the best describes your level. The calorie burn levels are described above to help with that.

    Hi Ted,
    I am a yo-yo dieter, I was very successful on weight watchers but stopped the program years ago…. I have gained about 40 lbs in the last year. I am 5’2, 210 lbs and 4 months pregnant. I have been advised that its ok to try to lose a couple lbs while pregnant since I am overweight to begin. The calculator is telling me about 1500 cals a day. Is that right?

    Hi Ted, I’m 206 lbs 6 ft and 26% body fat, i weight train 4-5 days per week and also run on 3 days out of the week but don’t exercise on weekends at all so am i moderate or lightly active? and also for the weekend do i take in the same calories/macros or drop down to sedentary intake due to no exercising on those days? Thank you!

    Reply
    • Ted

      Hi Nick, You should do two sets or possibly three sets of macros: 1. weight training day 2. weight training day/running day 3. rest day I would guess that they fall under 1. moderate 2. very active 3. sedentary. Check out the app MyMacros+ if you want to do three sets. https://healthyeater.com/mymacros-iifym-flexible-dieting
