Carb counting – the essential guide

After all, carbs are one of the three macronutrients that have the greatest impact on body glucose – too much of this can result in insulin resistance, making weight loss extremely difficult.

Why do you need to count carbs?

Carb counting is regularly used by those who need to control their blood glucose quite tightly such as those with type 1 diabetes or type 2 diabetes, those who want/need to be in nutritional ketosis, to help reverse insulin resistance, and those who want to control their hunger and fat-burning ability.

But whether you are needing to limit carbs for medical reasons or weight loss, the only way to do so is by actively counting carbs in foods and the quantities of those foods you choose to consume.

Carb counting 101

Firstly you need to understand the difference between total and net carbs.

TOTAL CARBS = sugars + starches +fibre

NET CARBS = total carbs – fibre 

Carbohydrates will be on the nutrition label are often broken down into carbohydrates, sugars, starch, and fiber. However, each brand may display its nutritional contents differently. And depending on which country you are in they will either show NET or TOTAL carbs and sometimes it isn’t clear which they are referring to.

Typically the US nutrition labels show TOTAL CARBS

Typically UK nutrition labels show NET CARBS

NZ/AUST show net carbs (and stating fibre is optional) 

And it’s for this reason that I do not recommend carbs counting apps such as MyFitnessPal and Carb Manager. There is too many incorrect “user added’ entries. Reader’s tell me every day they find errors because of a user misunderstanding total or net carbs and users from across the world who use total or net systems.

I recommend using nutritional values from cronometer.com You can sign up for a FREE account and track your daily carbs, electrolytes, and vitamins.

6 tips: How do I start counting carbs?

Although at first, it may seem like a daunting task to count carbs, when you start practicing it on a daily basis it becomes much easier. Plus, it is an extremely helpful tool for managing your weight loss and general health. 

Tip #1: Learn To Identify Which Foods Are Naturally High In Carbohydrates

Some foods are naturally higher in carb content than others and it’s very important to start to get a good grasp of knowledge on this, particularly when it comes to whole foods that won’t have nutritional labels attached to them in your local grocery stores such as potatoes or bananas.

Once you know which foods are high in carbs, you can either find low-carb alternatives or you can reduce the quantity of the higher-carb foods when consuming them. 

After a while, you will instinctively know which foods to avoid and which to enjoy.

The longer you live low-carb or keto, the less you need to carb count. Time spent at the beginning reading labels or looking at nutritional values is time well spent.

Don’t skip this steep learning curve.

Tip #2: Recognise Where Carbs Hide

Children looking over a ledge to see what\'s going on

Carbohydrates are easily hidden in sauces, dressings, and other condiments, especially those that have been sweetened. It’s one of the reasons that I strongly advocate for making your own homemade low-carb sauces. 

Sweetened yogurts and milk are also high in carbohydrates so reading the nutritional label on these items is a must!

And if you think the only sugar you need to look for is … sugar, think again There are over 50 names of sugar and the sneaky food manufacturers will use a variety of sugars so they fall lower in the list of ingredients to confuse you.

So honey, agave, fruit crystals, fruit syrup, apple concentrate, organic coconut nectar, HFCS, corn syrup solids, beet sugar … they’re all sugar.

It’s called “confusion marketing”.

Sugar is sugar no matter what you call it.

Tip #3: Choose Quality Carbs

When it comes to the keto diet, both quality of food and quantity of food matter and both should be considered.

If you only count carb values but don’t care where those carbs are coming from, you are considered to follow a dirty keto diet.

If however, you count carb values AND you ensure your carbs are from whole food nutrient-dense sources, you are considered to follow a clean keto diet.

Instead of getting your carb intake for the day through refined foods such as white flour, white bread, white rice, pastries, sodas, snacks, pasta, sweets, and breakfast cereals, opt for whole foods that are nutrient-dense and will keep you satiated for longer.

These types of foods include leafy green vegetables, berries, and other nutritious foods that offer a high percentage of fiber. 

The reason for choosing high-quality carbs is the wide range of nutrients that you will benefit from getting by consuming them. These include essential amino acids, essential fatty acids, vitamins, minerals, micronutrients, and health-promoting plant chemicals called phytonutrients which our bodies cannot make. These help to maintain a healthy immune system.

Quality carbs are also usually high in fiber which aids to slow the digestion of sugars and starches, preventing spikes in blood sugar and insulin closely associated with diabetes, heart disease, and weight gain!

Tip #4: Set Your Daily Carb Limit

Setting your daily carb limit depends on what you want to achieve as well as the type of diet you are following.

If you are unsure of how many carbs you should be eating per day, consider the following categories of carb levels. Generally, a low-carb diet is considered to be:

  • <100g/day = moderate low-carb
  • <50g/day = low-carb
  • <20g/day = keto

Many readers like to begin by simply reducing their carbs to a level that is sustainable and weight loss still occurs. Choose simple low-carb meals for beginners and begin to make easy low-carb side dishes.

Tip #5: Find A Carb Counting Method That Suits You

Some people love numbers while others stay well clear.

If you love crunching numbers then, by all means, do the various recipe calculations, factoring ingredient quantities, nutritional labels etc. But if this seems overwhelming to you, take note that there are many other methods at your disposal.

Tip #6: Test and Tweak Your Carb Counting Efforts

Once you have started to count your carbs on a regular basis, measure your progress, evaluate and then adjust if required.

For weight-loss purposes, you can measure your weight loss as the desired result of carb counting by recording your starting weight and incremental weight recordings going forward or measurements of body areas with a measuring tape.

Keeping a journal of how you feel is another great idea as you may start to see certain patterns that require adaptation. 

For those who prefer the digital route for recording stats and progress, there are countless carb counting apps online. Some are free while others come at a small price. All of them are designed to make the carb counting process that much easier. 

Serving size vs portion size

A serving size is the portion of food with calculated information on the food label.

If your portion size differs from the serving size then you will need to adjust the carb count accordingly.

I recommend calculating portion sizes when you have access to measuring tools such as a food scale or measuring cups otherwise you can estimate based on your fist being about 1 cup and a handful being about 1/2 cup.

The Plate Method

To use the plate method, divide your plate in half and then divide one half in half. You should then end up with one large section (for non-starchy vegetables and greens) and two smaller sections (one for protein and the other for quality fats). 

Hire someone to do the math for you

You could consult a dietician or healthcare practitioner to assist you in counting your carbs by creating a meal plan specific to your weight loss or health goals and then tracking your progress through follow-up consultations.

Even with this method though, you will be required to measure your food when preparing recipes that have been designed for you which is good practice for getting to learn visually what your portions should be and what foods you should work with. 

Use online resources such as carb counting apps or carb counting charts

As mentioned previously, there are many carb counting apps that you can use which will track your daily carb intake by simply adding the foods consumed. An alternative is to make use of a carb counting chart that you can download and refer to when selecting foods. 

If you’re interested in apps to help you with counting carbs, keep reading as there is an entire section below showing you the best apps!

Should you count calories or count carbs to lose weight?

banner with bathroom scales

The two common approaches to losing weight are either by counting calories or carb counting carbs.

For calorie counting, it’s total calories in versus total calories out and in order to lose weight, you need to have burned more calories than consumed. By being in a certain caloric deficit per day, you may see a corresponding weight loss over the course of that particular week. 

But this is a flawed system and does not take into consideration the effect food has on your hunger hormones and your fat storage hormones.

Weight gain is a hormone imbalance, not a calorie imbalance.

The keto diet places emphasis on consuming limited quality carbohydrates within the limit of 20 grams per day to reach and maintain a state of ketosis (burning fat for fuel instead of sugar) which results in weight loss. 

While each weight-loss method has its own pros and cons, there are two main reasons why I suggest that a carbohydrate counting method is superior to a calorie counting method:

Stay Within the Proper Macronutrients

A risk associated with the total calories method is the potential to lose sight of an optimal macronutrient split for efficient fat burning.

In other words, someone could still be in a calorie deficit but be consuming higher amounts of carbs and lower amounts of healthy fats compared to the keto follower.

In the former situation, this could result in experiences of cravings and hunger which could make the calorie deficit method unsustainable over the long-term and slow the metabolism.

More Easily Naviagte Through Plateaus

At certain points of weight loss, plateaus are experienced. When this happens, a keto dieter can easily adjust their carb content.

With the calorie deficit method, the metabolism eventually slows down as more calories are reduced which then makes further weight loss very difficult. It’s known as the “calorie deficit paradox”.

Can you eat carbs and still lose weight?

Yes, definitely! The keto diet is about eating quality foods within optimal quantities to facilitate nutritional ketosis which is when your body switches from burning sugars as fuel to burning fat.

These quality foods referred to also include whole, nutrient-dense carbohydrates that are high in fiber.

As the keto diet limits carbs to around 20 grams per day, it’s clear that carbs are very much still a part of the keto diet, albeit in smaller, healthier quantities that facilitate efficient fat burning. 

How do you count carbs for a diabetic?

banner showing carbs written in bread

Maintaining healthy normal stable levels of blood sugar is vitally important for anyone that has type 1 or 2 diabetes.

Many diabetics also test their blood sugars following certain foods to see how they, as an individual, react. For example, the sweeteners in many low-carb or keto bars may not affect the majority of consumers, but for some, sweeteners (such as sugar alcohols) may make their blood glucose skyrocket.

Since one of the best-known ways to maintain good blood sugar levels is through low-carb consumption, it’s a no-brainer that the keto diet and the practice of carb counting are extremely beneficial to diabetics. 

The ideal carb intake for those with diabetes is somewhat controversial yet studies have shown incredible improvements in blood sugar levels and weight loss among diabetics who were limited to 20 grams of carbs per day. 

With this said, it is always recommended to consult your medical doctor prior to making any dietary change, particularly if you have any existing medical conditions.

Carb Manager

Inaccurate and crowdsources data- can be clunky and constantly wants you to upgrade or buy books

The free version allows you to track carbs and offers easy-to-understand graphs, however, if you are looking for other health tracking functions then you’ll need to upgrade to the premium option. 

Readers have told me that the number of upsells and regular marketing emails annoying for the user. Crowdsourcing of nutritional data makes many of the values incorrect.

Set macros – May have inaccuracies – Many upsells


Inaccurate and crowdsources data.

This app is great for keeping track of all of your macronutrients but it can be somewhat cumbersome when trying to add various food items to the food diary. 

Crowdsourcing of nutritional data makes many of the values incorrect. Especially when the carb values aren’t clear whether they are TOTAL or NET carbs. So my readers have subtracted fibre from an already NET value, only to achieve a negative carb count, which is impossible.

What to do if you hate counting carbs?

I get it, tracking and counting are boring, and dull … but it works!

But if you’ve had decades of dieting and counting points, tracking numbers, or monitoring every single calorie, intuitive eating is for you.

  • Eat only from a small range of low-carb and keto food groups
  • Ensure your portion sizes are keeping you full, but not overfed
  • Eat only when hungry, stop when almost full
  • Stop snacking
  • Have an evening cut-off time after which you will not eat
  • Use your phone to take images of your meals, snacks and drinks to be a visual reminder of what you have enjoyed during the day. It’s amazing how extra coffees, and extra portion or a small snack can creep back into your day

Want to learn more? Want to finally control your appetite rather than your appetite controls you?

Take home notes

Counting carbs is an integral part of the keto diet and obtaining the weight-loss results you want to achieve as well as overall health. 

While it may be daunting to start for beginners, with consistency you will soon get the hang of it and be able to estimate portion sizes pretty accurately, even when you don’t have your measuring tools by your side. 

Keeping in mind that there will be a learning curve, in the beginning, will help you to stay at it and attain the results you deserve!

    Libby, one place I read about Keto and it says 20g carbs and then I read more and it says 20 net carbs. Which one is Supposed to be considered Keto. I really love listening to your videos. I really dont know where I mess up trying to do keto. Ive been trying to do it for couple of years but not doing something right. My husband doesnt want to eat the foods plus i had had sleeve surgery 6 years ago i am under lot of stress put on lot of my weight back on. I have been trying to pull the weight back off. I am lost. I never have the energy everyone claims they have from keto. Any advice

    1. Great question Christi, most people regard keto to be 20g NET carbs. As to your question about not losing weight, yes, stress can have an incredible influence on weight loss, but there can also be a huge number of other factors. Is carb creep occurring? Are you tracking? Are portion sizes creeping back up? How often are you snacking? If you want more help and would like to do some of our mini-challenges, you can join us inside Ditch The Carbs PRO and you can do the full 4-week QucikStart which goes back to basics and I coach you through everything you need to know so you can reach your goals AND stay there.

        Thanks for getting back to me. I dont have FB. My husband wont allow it. I try to stay at the 20 net carbs a day. I have tried using Chronometer but its very confusing to me. I do have carb manager to help with macros. Yes i keep up on carb manager all of my meals. I do have couple snacks a day. Most of the time the snack is cracklings. I had downloaded your books and plans a couple of years ago. I have read them. With the stomach surgery all recipes are to much. It throws me eating leftovers several days. Kind of get bored eating that many days of leftovers. Is there a way to join the pro plan without FB. I have had a couple of people start keto and will do with me and then they desert me. Then there is no one to talk to about things. Guess Im very insecure about this and need support all the time. By the way I live in Texas in a small country town called Moss Hill Texas. I love your energy and your passion about eating low carb and keto. Thats one reason why i keep trying.
