Is ‘Tracking Macros’ Sustainable?

The current nutritional trend is ‘Tracking Macros’, measuring and recording the amount of each of the three macronutrients (protein, carbohydrates and fat) you are consuming. The idea behind this is two-fold. Firstly, it (claims to) allow you to closely monitor how much energy you’re consuming, and secondly, it (claims to) regulates hormones in the body that are responsible for weight loss or weight gain.

There are however some problems with this approach. There are problems from a physiology perspective (which we’ll touch on in a moment), but more importantly, there are problems from a psychological perspective, which we’ll address now.

The problem is, too many people approach food as ‘nutritional science’, while in reality, it’s about ‘behavioural science’. Sure, counting calories and macros may work in the short term, but a short term approach only delivers short term results. As we discuss in our article
Why Your Diet And Weight Yoyo And What To Do About It“, not only are short term strategies ineffective, but they actually create physiological changes in your body that make future attempts are changing your body composition more difficult.

There’s one simple question to ask yourself to determine whether the habit or behaviour you’re looking to introduce is worth your time and effort…

“Can I easily do this every day for the rest of my life?”

If the answer is ‘no’, don’t introduce the behaviour. Not only will it not give you long term results, but when you break that habit, it will only go to reinforce to yourself that you’re the sort of person who doesn’t commit to the promises they set themselves – and that’s a slippery slope.

If you’re looking for long term results, and counting macros isn’t something you can see yourself doing for the coming decades, it may not be the best approach. Of course, if the changes you’re looking for are short term (you’ve got a wedding coming up or you need to reduce weight for a sporting competition etc), then this may be a great strategy for you. Just bear in mind that nothing comes for free, and short term strategies leading to short term success almost always result in long term failure.

This is one of the reasons that we have previously written about the uselessness of weight loss advice that tells people to just “burn more calories than they consume“. The problem isn’t that this advice isn’t accurate. It’s that this advice is useless. And it’s useless because it tells people WHAT needs to happen. We need to know HOW TO MAKE IT HAPPEN. We need to know how to create behaviour change.

Let’s move on to the physiological. Let’s pretend for a moment that you live in a test tube in a lab, and that your mind and your thoughts and your behaviours are controlled by wires entering your brain. In this fictional world, we’ve removed psychology from the equation.

Will counting macros be effective then?

Still no.

Precision Nutrition, a leading Nutrition Coaching Educational Organisation, gives five reasons that counting macros may not work from a ‘non-psychological’ perspective (sourced from here):

  1. Calorie counting and labelling is imprecise, with error rates in reported calories counts as high as a massive 50%.
  2. Although we may consume a certain amount of calories, the rates of absorption are highly variable between different foods, with an average error of 10%.
  3. Food preparation changes the caloric load and macronutrient breakdown of foods, by up to 90%.
  4. Different people absorb different amounts of calories from the same foods – largely due to differences in our gut microbiomes.
  5. Research shows people are notoriously bad at ‘eyeballing’ or ‘estimating’ how much food they’re actually consuming. So (aside from the fact that even weighing and measuring your food is ineffective as discussed in the four points above), unless you want to weigh and measure everything, forever, you’ll eventually drift away from your prescribed intake levels.

So, if the science is so sketchy, why do some people achieve success with counting calories and macros? Because it’s an IMPROVEMENT on what they’ve done before. If you go from having NO set plan of how to eat, to having SOME set plan of how to eat, there will be an improvement. It’s not difficult to improve from zero. But once again, we question the sustainability. And in the end, we’d rather you be ‘quite healthy’ forever, than ‘super healthy’ for a couple of weeks.

Sure, we’ll admit that counting macros may work on a psychological level for some people. But the segment of the population who’s wired for a life-time of weighing and measuring is small. Very small. Let’s say 5% of people are wired this way (and they have enough willpower to call on day after day, year after year), and 95% would be better suited to long-term automatic habits – cruise control, without the exhausting need to constantly draw on willpower. Why then is the field of nutrition coaching so heavily weighted towards the minority? Because it promises short term results. And that’s what people want. Instant gratification. The problem is, instant gratification is virtually never permanent. What we need is a behavioural approach.

What does that approach look like?

  1. Setting an outcome goal that you’re initially motivated to achieve that is supported by your values.
  2. Creating process goals (planned habits) that identify the actions required to reach an outcome, supported by an environment with a low barrier to action.
  3. Making a start – the key to forming habits.
  4. Build your ‘willpower muscle’ by consistently make choices that lead towards your desired outcome.
  5. Eventually, willpower won’t be required, as habits become automatic.

Range of Motion Nutrition Coaching offers a one-on-one behavioural approach to improving your nutritional habits. We recognise there is MUCH more to nutrition that the science of food. In fact, it’s more about the science of the mind. It’s about creating positive changes to people’s habits that are sustainable for the long term.

We use one-on-one consultations (in person or video call) with your Nutrition Coach to guide you through the process of finally building healthy, sustainable, long-term nutritional habits.

By building habits, we remove the need for discipline and willpower, and put healthy eating on autopilot.

It’s not for people who want to count calories and macros.
It’s not for people looking for a quick fix.
It’s not for people who just want a meal plan, not a plan of how to change habits.
It’s not for people with amazing willpower. We help people who struggle with willpower.

It IS for everyday people with everyday challenges.
People who want before and after habits, not before and after photos.
People who want to know HOW to change, not just WHAT to change.
People who want to make a healthy change that will last decades.
