Reducing weight is hard. And retaining it off in the long term is even harder.
Tens of millions of individuals attempt some form of weight reduction program yearly. However most who’re profitable will regain the burden over the next years.
In actual fact, individuals who undergo cycles of weight reduction and regain, a course of generally referred to as yo-yo weight-reduction plan, are more likely to weigh greater than individuals who don’t have restrictive consuming patterns. That is very true for ladies.
On this article, we’ll deal with calorie counting.
Though it is one of many best-known approaches to weight reduction, research have proven that it’s an ineffective approach to obtain and keep a wholesome weight in the long term.
A evaluation and meta-analysis inspecting 80 weight reduction medical trials supplies some proof. The authors in contrast completely different strategies of weight-reduction plan, together with low-calorie diets.
They discovered {that a} eating regimen centered on drastically lowering caloric consumption initially produces dramatic weight reduction. However individuals’s weight steadily rises again.
And on the 3-year mark, most individuals — round 80% — are quickly approaching their beginning weight.
Prof. Tim Spector informed us that “In actual life, these figures are more likely to be a lot worse with out the backup of all of the sources and psychological assist of a medical trial.”
Apparently, the scientists additionally discovered that individuals who tried to drop some pounds utilizing solely train misplaced the least from any group. In addition they put the burden again on the quickest.
However immediately, we’re specializing in calorie counting and why it doesn’t work.
Calorie counting: The fundamentals
On paper, calorie counting is sensible — in case you absorb fewer energy than you utilize up, you’ll drop some pounds. It’s a easy and alluring equation: Eat much less, transfer extra. Simple.
On the one hand, this arithmetic is correct. In case you can repeatedly absorb fewer energy than you’re burning, it’s going to work.
Over months and years, although, this plan falls aside as a result of we’re not easy machines.
Most individuals who attempt calorie counting and handle to scale back their calorie intakes will regain any weight they misplaced over the next years.
Right here, we’ll clarify the numerous flaws in counting energy, why it’s so troublesome, and why it doesn’t work in the long term.
We’ll additionally inform you what does work. And also you’ll be delighted to study that it doesn’t require a calculator. Spoiler alert: Meals high quality is essential.
Half 1: Why calorie counting is inconceivable
This text has two primary elements. Within the first, we clarify why precisely counting energy is inconceivable. Within the second, we define why calorie counting will not allow you to handle your weight.
What’s a calorie?
One calorie is the quantity of vitality it takes to heat up 1 kilogram of water from 0°C to 1°C.
And completely different macronutrients have various quantities of vitality. Roughly talking, it goes like this:
-
1 gram of carbohydrate supplies 4 energy
-
1 g of protein supplies 4 energy
-
1 g of fats supplies 9 energy
Nevertheless, these are averages, and the actual world isn’t common. So, once you see the energy listed on a meals label, that’s actually solely an estimate — quantities can fluctuate.
Legally talking, meals producers might be as much as 20% out of their estimates, which may very well be vital. A “100-calorie” snack, for example, may include something from 80–120 energy.
Plus, portion sizes are inconceivable to regulate precisely, and restaurant estimates of energy can fluctuate by greater than 50%.
Even skilled dietitians battle to measure their intakes with precision.
Then there’s the impression of cooking, and labels do not take this under consideration.
A uncooked stick of celery has 6 energy, nevertheless it has six instances that (36 energy) when it is cooked. Throughout the board, the caloric content material of meals might be vastly affected by cooking.
So, that’s the primary fly within the calorie counting ointment.
An absorbing truth
As we’ve seen, you’ll be able to by no means be 100% certain what number of energy you’ve eaten.
However the points don’t cease there. Even in case you knew precisely what number of energy have been in your meal, you would not know what number of you’ve truly absorbed.
For example, in a single examine, scientists decided what number of energy individuals had absorbed from almonds and in contrast these outcomes to the usual technique of calculating energy in meals.
This technique — referred to as the Atwater normal issue system — works out the calorie contents of meals by measuring their carbohydrate, fats, protein, and fiber contents.
The researchers discovered that, on common, individuals absorbed 32% much less vitality than the energy estimated by the Atwater technique.
And individuals’ responses different considerably: They absorbed between 56 and 168 energy from 1 ounce of almonds.
So, given the identical variety of almonds, some individuals will take in virtually thrice as a lot vitality.
Construction issues
In the meantime, the construction of meals impacts what number of energy you get from it.
Right here’s an excessive instance: Think about you swallowed a metallic ball crammed with 500 energy of chocolate.
The little ball received’t get damaged down in your intestine, so the chocolate inside received’t be damaged down and digested. Each will exit in your poop, offering you with 0 energy.
In different phrases, not all of the vitality in meals is likely to be out there. And what determines this availability is the meals matrix.
For this reason there’s a distinction between consuming some corn on the cob and tortilla chips, although they might have the identical estimated variety of energy.
What’s the meals matrix?
The meals matrix is the meals’s construction — the way it’s held collectively — and the compounds it comprises.
Occupied with the matrix helps clarify why fruit juice is much less wholesome than complete fruit. While you break down the fruit’s construction, your physique can digest it shortly and extract the vitality extra simply.

A examine from 1980 supplies a very good instance. The researchers gave individuals complete peanuts, peanut butter, or peanut oil.
They discovered that when individuals ate complete peanuts, they excreted extra fats than the opposite individuals. This implies they absorbed much less of the fats — and its energy.
Those that consumed the peanut oil pooped out the least fats, in order that they absorbed probably the most energy.
A examine revealed in 2007 generated related outcomes: Those that had the peanut oil absorbed extra vitality.
Why does this occur?
A lot of the fats in nuts is trapped inside cell partitions that neither your intestine bugs nor digestive enzymes can break down.
So, as with the chocolate-filled metallic ball, in case you can’t entry the vitality, it passes by means of you.
But when these cell partitions are destroyed by processing, that vitality turns into out there.
The calorie counts for 100 g of complete peanuts and 100 g of pulverized peanuts could be the identical on a meals label.
In actuality, you’ll doubtless take in a lot fewer energy from the entire nuts.
Half 2: Why calorie counting does not work
So, we have established that counting energy can by no means be correct. Now, we’ll clarify why calorie counting — even when it was attainable — would not allow you to handle your weight.
Macronutrients make a distinction
Analysis has proven that the kind of vitamins in meals makes a distinction in the case of weight reduction.
For example, a evaluation on the subject explains: “Excessive-protein and/or low-carbohydrate diets do yield better weight losses after 3–6 months of therapy than do low-fat diets.”
The authors observe that even when individuals devour roughly the identical variety of energy, the quantity of weight they lose relies on the macronutrient contents of their diets. Energy aren’t king.
Excessive-calorie meals aren’t equal
Nuts, avocados, and olive oil are well-known for being excessive in energy. An avocado, for example, has an analogous calorie rely to a burger.
However it’s not the variety of energy that issues. As an alternative, the standard of the meals is most necessary.
The variety of energy in a meals doesn’t inform you something concerning the different vitamins current, how good it’s in your intestine microbiome, how shortly it will get absorbed, or what number of components and preservatives it comprises.
Meals is a lot greater than the vitality it supplies.
It’s clear that 100 energy of avocado and 100 energy of soda don’t have very a lot in frequent.
The soda will present subsequent to no dietary advantages. The avocado, alternatively, comprises a variety of nutritional vitamins and minerals, fiber to gasoline your intestine microbiome, antioxidants, and extra.
A have a look at ultra-processed meals
In lots of Western nations, ultra-processed meals make up a substantial chunk of our diets. In america and United Kingdom, they account for greater than half of the inhabitants’s vitality consumption, and much more in youngsters.
It’s more and more clear that ultra-processed meals play an necessary half in weight acquire.
You might need already guessed, however the excessive calorie contents of those meals aren’t the entire drawback. The first subject is their low high quality.
As within the avocado versus soda instance above, once you eat ultra-processed meals, you’re not getting the vitamins your physique wants or the fiber that your intestine micro organism must thrive.
No matter their calorie contents, these meals are designed to be hyper-palatable. This implies you received’t need to cease consuming them — they’re scientifically designed to be scrumptious, not nutritious.
As a result of ultra-processed meals lack fiber and protein, they received’t preserve you full for lengthy.
So, you may end up looking for snacks shortly after consuming, as these meals usually enhance your urge for food greater than equal complete meals.
Lacking out on vitamins
When counting energy, you are likely to fixate on the calorie figures alone. This may imply selecting meals just because their calorie counts are low. Typically, it’d imply selecting ultra-processed “eating regimen” snacks.
And since these merchandise are nutrient-light, you might miss out on important nutritional vitamins and minerals.
Equally, in case you’ve consumed a excessive variety of energy early within the day — possibly a slice of cheesecake — you may severely limit your self within the afternoon to “catch up.”
This may imply skipping a meal once you’d sometimes have greens or different nutrient-dense meals.
And as we’ve talked about, some meals — like avocados and olive oil — are excessive in energy but in addition extremely nutritious. Chopping out these meals to maintain your calorie rely in verify is counterproductive.
It’s higher so as to add these to your eating regimen moderately than skip them due to their calorie contents.
Disordered consuming
By now, we’ve established that calorie counting is way from one of the simplest ways to drop some pounds.
There’s additionally rising proof that for some individuals, it might enhance the chance of disordered consuming.
Disordered consuming refers to behaviors which can be a part of consuming issues. Some examples embody compulsive consuming, binge consuming, and chaotic consuming patterns.
For example, a examine from 2017 recruited individuals with current consuming issues.
All of the individuals already used a selected app that counts energy and different well being knowledge.
Round three-quarters of the individuals reported that the calorie counting app contributed to their consuming dysfunction.
Equally, one other examine from the identical yr recognized hyperlinks between calorie monitoring apps and will increase in disordered consuming.
Though researchers are nonetheless investigating this relationship, proof is mounting that calorie counting apps are unhealthy information, particularly for individuals vulnerable to disordered consuming.
So, what do you have to do?
ZOE runs the biggest vitamin examine of its type. We all know that everybody is completely different, and other people reply to meals in another way. So, there’s no one-size-fits-all method to weight reduction.
Crucial factor you are able to do to assist attain your long-term well being targets is to deal with meals high quality and ignore energy.
This implies consuming a various vary of crops. Prof. Tim Spector suggests aiming for 30 completely different crops every week, based mostly on his analysis.
Somewhat than specializing in eradicating issues out of your eating regimen, deal with including greens, nuts, seeds, complete grains, legumes, and fermented meals.
However in case you fancy a slice of cheesecake each from time to time, go for it. Meals needs to be loved, not counted.
