Get Your Macros Straight in Two Minutes - Just Three Steps for Low- and High-Carbohydrate Diets | Includes Examples
If you want to "hit your macros", you better hurry to find out what those macros are, before you start weighing everything. So, here are the three steps you got to take before you start ;-) |
Don't forget that health and looking good naked require eating right and working out!
- Step 1: Find your / a client's daily energy requirements: This may be the fastest or longest-taking step. If you already know how much energy you want to consume or have a client consume on a daily basis, skip this step and go right to step 2.
You're still there? Well, ok. This means you don't know how much energy you want to consume or prescribe and want me to tell you how to calculate that? Well, I will do that, but I personally don't recommend to calculate your requirements, and I am pretty sure that after you see my example calculation you will be similarly convinced that only Mr and Mrs Average will get good results with the most used equation to calculate your resting metabolic rate (RER) and total energy requirements (TEE) - the Harris-Benedict equation:Equation 1: The Harris-Benedict Equation in all its usless glory - don't rely on this or any other formula when you're trying to estimate your or a client's dietary requirements. - Obese Man - obese at 175kg body mass, he is 27 years old, but looks like an overweight teenager, with his body size of only 179 cm he's having an extra-hard time moving his frame to the fridge and back, which is - as he freely admits - the only "exercise" he has gotten ever since he's lost his job 5 years ago
- Active Woman - active, middle-aged, weighs 58 kg, you checked, because you know middle-aged women lie about their weight, her passport says age 47, her body size is 160 cm, and she says that she jogs regularly ("Roughly three times a week, I'd say"), no HIT, HIIT or strength training
- 1.2 - non-active couch potato and office worker,
- 1.3 - people who use the bike or walk or do other light physical exercise 1-2x/wk
- 1.4 - people who jog or do similarly medium intense physically activity 3-5x/wk
- 1.6 - the average recreational active gymrat who trains intensely at least 3x/wk
- 1.7 - someone who lives in the gym and takes the stairs ;-)
Equation 2: Calculation of the total daily energy requirement for the two example clients.
So, I hope you see that you are way better off if you are having your clients log their food intakes for a week (at least three days) and determine their intake (or yours if you're doing this for yourself) by dividing the total energy intake by 7.
Every client should to a long(er)-term food log: If you don't have data on how much and what exactly a client eats, you cannot work with him. It's also important to get an idea of what he likes and doesn't like. After all, the best diet is useless if a client does not adhere to it - and we all know that a candy lover on a eggs and bacon diet is going to have a harder time than a bacon lover on a ketogenic diet. Also, for clients, this obviously means that any trainer who gives you a detailed meal-plan without having seen at least a three-day food log, is someone you should not rely on.
- Using the food log will not only allow you to avoid bogus predictions for people who are not "average", but it will also allow you to
- estimate the previously mentioned food quality of your / your clients diet,
- decide based on what you or he / she like whether a high carb or low carb approach is the one with a higher chance of 100% adherence and
- see that the current energy intake is at a level that would hardly sustain a toddler, due to years of dieting and meanwhile useless reductions in energy intake (if that's the case, click here)
- Now that you hopefully know how much energy you or your client need on daily basis, there's one last thing you have to do before you proceed to step #2: Determine if you, he or shee needs just the TER or 15-35% less (in very overweight clients even 40%-50% less) or 10-15% more in order to lose body fat or gain muscle, respectively.
- Step 2: Decide whether you want to go high or low carbohydrate: Now that you know "exactly" how much energy you or your client are going to consume on a daily basis, it's about time to decide which dietary prescription, i.e. high or low carbohydrate, you or your client are going to follow.
Unless you're going to go keto which would require you to set a limit of ~10-15g of protein per meal to stay in full ketosis, you still have 30s to think about whether it should be high or low carb, while you're determining the protein baselines which are:- 1.2-2.2 g/kg (2.0g = suggested, unless lightweight) total weight for men
- 1.2-1.8 g/kg (1.5g = suggested, unless lightweigh) total weight for women
I think your 30s time for consideration are over and hope you've used the time wisely to decide if you want to go low or high carb? In general, the rule of thumb is: "The fatter you are, the greater the low-carb advantage is going to be." Now, as a SuppVersity reader you've read enough about low and high carbohydrate diets, their advantages and pitfalls on the SuppVersity to be able to decide, so (wo-)man up and take the responsibility and use - 40-100g (80g suggested for men; 50g = suggested for women) as a minimum daily fat intake for yourself or clients on high carbohydrate diets or
- 50-120g (90g = suggested for men; 60g = suggested for women) as a minimum daily carbohydrate intake for yourself or clients on low carbohydrate diets and
- <20g of carbohydrates (best divided across meals) on a truly ketogenic diet
- Step 3: Calculate the amount of your primary energy source: The last step is actually the easiest one. You take the values from the previous steps, i.e. your total daily energy requirement (+/ - X% if dieting or bulking) and subtract the energy equivalents from Step #2 by filling your data into either the high or the low carbohydrate equation below:
Equation 3: Use the results from steps 1-2 to calculate the amount of the main nutrient (in g/day).
So, assuming we'd chosen the standard approach for our two previously cited clients with a weight maintenance high carbohydrate diet (intake at TER) for the female and a restricted diet for the obese guy (TER - 30% = 2292.62 kcal/day), we would end up with...- Obese man - low carbohydrate approach, maximal carbohydrate intake 50g (because he's very insulin resistant), protein intake at 1.2 g/kg (=210g total per day | we use the lowest value, because due to his extreme body weight even that will get us way beyond the ~30g/meal rule).
Figure 1: Results of the macro calculation for the obese man. Percentages expressed rel. to total macro intake (in g | left) and rel. to total energy intake (in kcal | right). - Active woman - high carbohydrate approach (because she doesn't like fat), maximal fat intake 45g (on the lower side, because her TER is relatively low, protein intake at 1.5g/kg (=87 g, that's minimally below the 30g/meal rule, but using a higher value would reduce her CHO intake to levels that have her run largely on gluconeogenesis which is bad for everyone and particularly nasty for women whose endocrine system tanks easily); in order not to starve her, we also assume a more realistic TER of 1,250kcal/day.

- Obese man - low carbohydrate approach, maximal carbohydrate intake 50g (because he's very insulin resistant), protein intake at 1.2 g/kg (=210g total per day | we use the lowest value, because due to his extreme body weight even that will get us way beyond the ~30g/meal rule).
If you assume that the amount of food you or a client eats is way too little, because you, he or she have been dieting or even developed an eating disorder, here are additional ways to estimate the real energy requirement and to get yourself, him or her back on track. I have to warn you, though, this will be a tough time for everyone involved | read more |
(*) Well, unless you feel you have to tweak the result, which is often necessary if you're dealing with people who are "extreme" as in "extremely lean / muscular", "extremely active" or "extremely overweight". In that, I suggest you keep in mind that...
- ideally, you want to have enough protein in your diet to make sure that there's room for at least three meals with 30g or more of high EAA protein in them across the day, irrespective of what your or your clients goal is (unless it's becoming a fat slob obviously),
- it may be a bad idea to go much lower than 50% of your or your clients body weight in grams on fats (i.e. don't go below 50g for a 100kg client), because if there's almost no fat in one's diet, the skin, the endocrine system and the overall health are going to deteriorate over time,
- that you should avoid making protein the major source of energy in the diet; while it's good to have plenty of protein, a diet that has virtually no carbs and no fats will make the liver work overtime and convert most of the protein to glucose that's not sustainable in the long run and a fast-track to fatigue for most people (Note: all the high protein studies showing magnificent results still have large amounts of the "energy macros" fats and carbohydrate in the diet, in the impressive study by Antonio et al. (2014), for example the carbohydrate intake was way beyond 200g and the fat intake was somewhere between 50-100g).
