6 reasons why calorie counting is a bad idea

Is counting calories our downfall?

An introduction to calorie counting

For many of us, certainly when trying to lose weight, calorie counting comes top of mind. This has been drilled into us, and to be fair, there is some truth in it. To lose weight we need to be expending more energy than we are consuming – this is a law of physics, there’s no disputing it. However, what can be disputed is how we go about doing this – you can still lose weight (if this is necessary), and more importantly, support a healthy body and metabolism without having to obsess over every calorie. Here I explain 6 reasons why calorie counting may not be the best practice.

1. You probably don’t know exactly how many calories you should be consuming anyway

Although you may need to expend more calories than you are consuming to lose weight, do you know where your basal metabolic rate is sitting? Doubtful. The ball park figure of 2000 calories is thrown around, but actually this is an AVERAGE. A very rough one at that. Depending on your body composition, activity levels, and funnily enough, what we eat, the amount of calories we burn can greatly varies. 

Around 10% of the calories we expend each day is as a result of digesting the food we eat – and did you know that by eating good quality, whole foods, we can expend up to 50% extra calories than when eating processed rubbish? So, if you’re obsessing over a specific number of calories each day, it most likely isn’t accurate.

2. Obsessing over labels means more processed foods

Too many people, worryingly, seem to know exactly how many calories they are consuming, to the single calorie, each day, which means they are reading each and every food label. Hold on, if you’re reading every label to get a perfect calculation (all the ones that scan successfully on your Slimming World app) this means you aren’t likely to be eating much fresh food... only packaged  foods have labels, and packaged foods are often processed. 

We can get rough estimates of the calories of fresh foods, but we know that these can vary slightly with how and where the foods are grown, and this is just fine with us – it’s natural!

3. You risk counting calories rather than nutrients

Calories are calories... a pint of beer contains around the same calories as a small fillet of salmon. But what’s the crucial difference? The nutrients that they contain, that’s what. 

Alcohol is an extreme example, but actually, many processed foods aren’t much better – they have what we call empty calories.  Empty calories mean that yes, they may provide us with energy initially, but the calories are used very quickly for energy so we aren’t able to store much for later, and they are also generally very low in nutrients.

Instead, good quality fats, complex carbohydrates and protein can provide longer-lasting resources that we can use for energy. They also help keep us full up and satisfied, plus, keep our intake of essential vitamins and minerals tip top.

4. Fats are likely to take a back seat

If you’re obsessing over calories then no doubt you’ll be opting for the ‘low calorie’ options wherever possible. One big problem with that is that you’re most likely to be missing out on healthy fats. Fat has been wrongly demonised in the past which has led to the over consumption of carbohydrates and sugar (hello diabetes epidemic!). ‘Low fat’ products are often loaded with sugar; definitely something to be aware of.

Fats are actually extremely important for supporting our metabolism – they help with the manufacturing of hormones which are important for helping to keep us lean. So, believe it or not, good fats mean a healthy body.

5. Strict calorie restriction can have the opposite effects

Although, as before, generally we need to be expending more energy than we are consuming in order to lose weight, there is a catch. If we cut our calories too drastically, over time our bodies go into survival mode (it thinks there is a famine!) so it tries to store as much energy as possible. Your metabolism slows and you store more energy, which means you risk putting on weight. The main issue comes if you start eating normally again (inevitable on many of these unsustainable plans) because your metabolism has slowed and you’re stocking up on some extra calories – a sure way to pile on the pounds.

6. Obsessive behaviours aren’t healthy

Plain and simple, we aren’t designed to count calories. We should be eating what we need to fuel our bodies, eating when we feel hungry and stopping when we are full, end of. Anything outwith this simply isn’t natural. Plus, you do risk taking all of the pleasure out of eating! Too meticulous over ingredients, quantities and portion sizes, you risk making eating a boring and, let’s be honest, draining chore. Eating should be fun and not a burden – enjoy it!

My tips...

To sum up, here are some of my tips for enjoying a calorie-counting-free diet and lifestyle. 

Firstly, listen to your body – eat what you feel you need (within reason, think fresh ingredients), eat when you’re hungry and don’t overeat. Your body will soon tell you when you’re full – if you eat the right foods and slowly enough that is. We know that fats and protein are more satiating than carbohydrates, so always have a balanced plate which includes sources of good quality protein and fats. 

Next, take your time over food. Not only does this mean you can enjoy the flavours and textures, but you will also chew your food properly which means you can digest and make the most of all the lovely nutrients it contains! Eating slower will also mean you will feel fuller more quickly – long before you’ve manage to eat yourself into a food coma! 

In terms of maintaining a healthy weight, in most cases, relaxing and eating fresh (this really is key) will mean that your body finds its own natural weight.

    Only you can know your body. And eating healthy is always good for you and this should be through out your life to say healthy.

    I have just downloaded a fitness app. Even though I think the app is brilliant. It is based on calorie counting. I think it is difficult to get an accurate count on calories consumed and all this counting is tiresome. I think eating the right foods and getting the right nutrients is more important along with daily exercise.

      Hi Carol, yes, often apps such as the one you describe can be a useful guide to initially help you get on the right track in terms of improving your diet; however I don’t believe that we should be relying on them completely, and worrying over every miniscule detail. The app can hopefully help you get into the routine of eating well, improving lifestyle habits until eventually, this will be second nature for you and you no longer need to use this as a guide. Good luck!

    I love this article, agree with the idea of eating fresh foods, but also an odd treat doesn't kill you, much easier to eat properly when you know you can have an occasional treat

      Hi Susanne, thank you for your comments. Yes, exactly. Being too restrictive can easily develop into obsessive habits which simply isn't healthy. So allowing yourself the odd treat now and again sounds like a sensible and realistic approach to me!
