Low Carb

How Low Carb is Low Carb?

How few carbs are there in a low-carb diet? It depends. It depends on what you’re trying to achieve and who you are.

Generally speaking, the fewer carbs the more effective it will be. Faster weight loss without hunger. More rapid and powerful reversal of type 2 diabetes. But also more restrictive and possibly more challenging.

Here are three examples of how a low-carb meal can look, depending on how many carbs you eat per day (the yellow stuff is delicious herb butter).

 

Ketogenic

Under 20 grams per dayStrict low carb(this meal: 6 grams)

Moderate

20-50 grams per daymoderate low carb(this meal: 16 grams)

Liberal

50-100 grams per dayLiberal low carb(this meal, including
sweet potatoes: 37 grams)


Our definition

Here’s the way we define different levels of low carb at Diet Doctor:

  • Ketogenic low carb <20 gram carbs per day. This is a ketogenic diet (if protein intake is moderate). This level is defined as below 4 energy percent carbs in our recipes, where we also keep the protein level low or moderate (excess protein is converted to carbohydrates in the body). Previously we often called this “strict low carb”, but as the word “keto” or “ketogenic” became commonly used we switched to only use this term, for simplicity.
  • Moderate low carb 20-50 grams per day. This level is defined as between 4-10 E% carbs in our recipes
  • Liberal low carb 50-100 grams per day. This means 10-20 E% carbs in our recipes

For comparison, a regular Western diet can easily contain 250 grams of carbs or more in a day, most of them bad refined carbs, including sugar.

Fibre

The above numbers refer to digestible carbs, and discount the fibre. You can deduct them from your carb counts, i.e. eat all the natural fibre you want from vegetables, for example.

Another word for digestible carbs, with the fiber deducted, is “net carbs”.

However, don’t be fooled by the label “net carbs” on processed products, like chocolate bars. That’s usually just a way to trick you, and these products are often full of sugar alcohols with negative effects on your weight and blood sugar. I suggest not eating anything with the words “net carbs” printed on it.

How to choose

Some people need to keep the carbs very low for maximum effect – a strict low-carb diet. This includes many people with significant weight issues, diabetes (mainly type 2) and food or sugar addiction, for example.

Others – less carb-intolerant people – do great on a more liberal low-carb diet. This also minimizes the risk of any side effects.

A third group of healthy, lean, active people may not even need to eat very low carb, as long as they mainly eat unprocessed slow carbs.

If you want to start doing low carb, I suggest starting out on a strict version, just to experience the power of it. Later, as you hopefully approach your weight and health goals, you can try adding more natural carbs to see how much you tolerate.

    Hey im on low carb at the moment 30 to 50 thinking of moving to 50 to 100 can anyone give me advice on how to do this without any side effects? Or what are the most common side effects thanks😊

    I have had success in the past with LCHF eating. I lost 22 pounds. I felt great had lots of energy, my skin was clear and the brain fog was gone along with the headaches. I have not eaten gluten or processed food for 10 years so it wasn't a difficult adjustment for me.
    I have increased my carb intake from low to moderate and have had an increase of 15 pounds in the past 5 months so I reduced the carbs back to the low carb meal plan. I have not had success with it this time, i go down a couple of pounds then right back up. It is so frustrating. I have hypothyroidism, could that have something to do with my struggle? Are there special considerations for people with this condition when eating LHF?

    The foods are disgusting. Eating fat in majority is NOT natural and normal at all. No weight loss whatsoever in 1 week worse my blood pressure went up. Will give this 1 more week if the same i will switch to Rina diet which helped me lose 5kg in 1 months (fat loss not water). Theory for keto sounds right practice sucks. Not to mention you must be rich to afford this in Australia

    Hi,
    I am very new to keto diet but I'd love to give it a go. Now I want the under 20 carbs food plan how much protein and fat can I consume. Please note I am so new you have to break things down for me to understand and not ask even more questions. I don't drink coffee so could I replace that with a none flavored protein shake which says no carbs on the lebel? Do I add similar to the coffee butter and coconut oil?.

    Please help and thank you for every effort made in advance.
    Xoxo
