Questions and answers about LCHF

Frågor och svar om LCHFHere are common questions and answers about low carb high fat (LCHF) nutrition and health:

Is saturated fat dangerous?

No. That is an old and disproven theory. It’s been a mistake from the beginning. More.

I started eating LCHF / very low carb and I feel dizzy / a headache / tired?

Dizziness / headaches and similar symtoms are common during the first week as your body adapt to a very low carb diet. These symptoms usually go away in a few days.

Adding a bit more carbs to the meals reduces the symptoms but can slow the adaptation (and weight loss).

Another possibility is that you are dehydrated / low on salt. When starting a very low carb there is extra loss of salt and fluids through the kidneys in the first weeks, until the body adapts. Drinking some extra fluid and putting some extra salt on your food during the first week can avoid this problem and often cures the symptoms. Alternatively you can drink some buillon a few times a day.

Do you use blood pressure medication? A very low carb diet can lower high blood pressure, and medication may need to be reduced in that case. Low blood pressure may result in dizziness.

Why are Asian rice eaters thin?

Probably because they do not eat a lot of sugar or refined starch. More.

What about gallstones and LCHF?

High fat food can give you short term trouble if you already have gallstones. Low fat food gives you gallstones in the long term. More.

Can you eat LCHF if you’ve had your gallbladder removed? Yes.

Can you eat low carb cookies / bread / pasta and lose weight?

That is probably not a good idea:

Do you get cancer from eating red meat?

Highly unlikely, although favoring unprocessed meat is the healthiest choice. Replacing meat with processed carbs may be one of the worst things you can do for your health and weight. More. 

Do you get hypothyroidism on a very low carb diet?

No, hardly on a well-formulated low carb diet, meaning you replace the energy from carbs by eating more fat. In scientific studies on LCHF there are no problems with the thyroid and I see no new thyroid issues in my patients going strictly low carb.

However, starvation can lead to hypothyroidism, and if you remove carbs AND fat from your diet you will be starving. So you do need to eat carbs or fat to fuel your body.

Bottom line: A LCHF diet is fine for your thyroid. More.

Is there scientific proof that LCHF is good for weight / blood sugar / cholesterol / blood pressure?

Yes.

Are studies showing better weight loss on low carb diets sponsored by the meat industry or the Atkins foundation?

Yes, a few of them are. But repeated independent studies show the same results.

Does insulin play a role in weight gain / loss?

Yes, it’s absolutely crucial in most cases. Some bloggers have objections but they do not change biochemical facts. More.

Can you drink alcohol on LCHF?

Sure, in moderate amounts. But beer and sweet drinks need to be avoided. Choose wine or non-sweetened liquor. More.

Is salt dangerous?

No. At least not in moderate amounts. More.

What’s a good LCHF breakfast except for eggs?

Perhaps this.

Can you eat fruit on LCHF?

Only occasionally, as an exception, if you want to be strict and get the maximum effect. Fruit contains a lot of sugar. Fruit is candy from nature.

Why are Americans obese?

This is why.

    Hi everyone...
    This was probably discussed here already but there are just to many comments to read them all.
    So i'm sorry if this is a repost...

    Anyway..
    So i'm eating LCHF for a couple of days now... I like it, i feel better and everything... BUT....

    I'm constantly hungry! When i eat i feel like i could just eat huge amounts of food and never get full... And even if i somehow manage to eat so that i feel full at the moment... i somehow feel hungry after an hour or so... And it's driving me nuts...

    Also is eating like 4 eggs every day too much? Or are eggs ok no matter the quantity?

    Thanks for any kind of help!
    Boris.

    Its lack of glucose spikes.. and if one get those one get a reward.. namly Dopamin.. then you get satisfyed!

    Its about eating for reward!

    It goes over after some more days.. at least if you get your energy/fat/calories.

    One shouldnt eat more then 20 eggs whith majo a day.. becuse then it gonna be excesses of calories.

    Eggs is one of the most nutrient food one can eat.

    Hi Doc :)

    I am sort of following the Paleo but with a bit of dairy and I have a question regarding the carb issue - I make a seed cracker that has chia, pepitas, sunflower seeds, white & black sesame seeds and flax seeds which I eat with lots of butter (yummy!) - would this be considered as too much carb? Also, for nuts (which I love) - how much is too much?
    Thanks for your reply!
    Shirin :)

    Its only you and your medical/metbolic conditition that can answer that!

    You know there are many people that eat a lot more carbs then that.. and are healty!

    If you eats proper meals and take those crackers for evening tea or at breakfast it cant do any harm.. I think!

    And it goes for nuts too.. nuts are not real meals.. they are tasty, some of them have kind of benefits.. like RS, minerals, fats and so on.

    Soo.. as long nuts and cracker dont is instead of real meals they are part of healty life style.

    Like some people bread is not my problem, it's sweets. I have found that peanut butter and whipped cream calms my cravings. Is it bad to eat that, if not how much is too much in a day?

    I was diagnosed type 2 type 2 diabetic 3 weeks ago. I started LCHF and I have lost 4 kg already.I am 58 ears old and have always continued to play 5 a side football with guys who are aged between 16 and 30 who are friends of my son. In the last 2 years I have begun to slow down and was considering packing up. I felt very stiff after games and increasingly asthmatic. Since my LCHF diet started apart from the first week when I felt quite weak, my stamina, my breathing capacity and my mobility has improved remarkably. Last night my energy levels were such that I could no stop running and my circulation and sweating just felt great. The youngsters could not believe where I had got all the energy from and nor could I. It is like a miracle. My target was to play till 60 but now I am thinking of revising my target to 65. Had I not been diagnosed as a diabetic I would never have changed my diet because I always thought it was about eating less. I will send photos of me playing footbal soon.!!

    hope this is not too late -eat less yogurt and increase butter

    Trying to get on top of this however I'm having difficulty coming to terms with a few things. Grains are apparently out, however seeds are permissible. They way I see it, beans must surely be seeds since they are not in heads as in grains. Why are they not included?

    As I'm on Warfarin I am limited to the amount of green intake or should I say it must be daily which can be not a likely scenario. Tomatoes are suppose to be a "health" item in particular to prostate health etc, what is the alternative?

    Thanks for you input.

    Its becuse moste of them is high in carbs, goes for lentils too.

    Well you have a special condition.. otherwise one recomend people to eat ther veggies, many eats to litle veggies frome the beginning!

    Becuse, if you cut out tubers, moste fruit, limiting dairys, limiting beans and lentils cuts out all seeds, one probably need the veggies for water soluble vitamines!

    Hi, is it possible to eat LCHF Monday - Friday and on the weekend eat regular (over 20 carbs). Then on Monday start all over again?
    Reply: #469
  19. Zepp
    Its always possible to eat real food every day!

    Its more about if you need to be in ketosis or not?

    Most people dont need to be in ketosis all the time.

    Its only people that have problems with hyperinsulinemia that need to be in ketosis for a long time.

    I am confused about total carbs vs, net carbs. I remember reading that LCHF counts total not net. On a keto website, they insist that only net carbs be counted.
    Reply: #471
  21. Zepp
    Its net carbs.. those how is digestible and converts to blood sugar!

    If you look at a European package, there is carbs only those that are digestble, fibers are labled separatly.

    Soo.. total carbs is for Europe and net carbs is for America.

    But there is a thing to notice, some manufacturer of low carb products are freaking lyers, but thats for those that manufacture bread, pasta, candy and such things!

    ive been following a LCHF diet for several months and I'm not losing weight. Could medications be to blame? I take serequel for bipolar, lamictal for mood, and Kilonopine for sleep. My pharmacist said that it probably is the serequel and said without diet and exercise I will probably continue to gain weight. I'm 5'5 and have always weighed about 140. Now I'm up 15 pounds heavier but following the LCHF religiously and exercising .....still 15 pounds up. Any insights on medications and effects on successful weight loss following LCHF?

    I just started my low carb diet. I find myself reading labels and became confused.
    The label gives me the amount of salt and carbs in grams. I used to know what a gram were when I was in collage. I use very little table salt. When I do, it is Sea Salt. The salt and carb grams are pretty high in some foods. What it high for my diet? I picked up a soup with 560 grams of salt. 25 grams of carbs. I wish to know what I am doing.
    Can you help?
    Thank you
    David

    Hi David,
    1 pound is 453.6 grams. In other words 1 kg (kilogram = 1000 g) equals 2.2 pounds.
    The amount of salt you mention is well over a pound which seems to be rather suspicious in a can (?) of soup. Normally nutrition values are provided on the basis of 100 grams of product, often the serving size and corresponding nutrient values are also listed.
    Depending on your health status and goals, 25 grams of net carbs should be the upper limit for a single meal, considering you have no more than 3 meals daily. Net carbs means total carbohydrates minus dietary fibers.
    If you are more used to teaspoons of salt and sugar, 1 teaspoon is around 4 grams of both.
  25. David
    Hi Erdoke
    I must have lost my mind when I hit 75...
    How about mg instead of grams.
    Thank you for your answer. It helped.

    You know.. its about calories in the end anyhow.. so way start starving?

    The only side effect is that you probably lose a litle fat and gain som muscles.

    would excess protein consumption lead to weight gain while on LCHF diet?
    Reply: #479
  29. Zepp
    Mayby, mayby not!

    You know weight dont tell that much about your bodily composistion, your healt and how you feel.

    And then.. whats excess protein.. many do eat to litte protein and to much carbs/sugar!

    Those how like to gain muscles tryes to eat more protein for extra protein syntesis.

    Let say that dayly demand is betwen 1-2 grams/kilo a day.. if one eat more and dont do extra hevy weight lifting you gonna pee the extras out, thats not a good ide and often expensive.

    Hi there! Sorry if this is the wrong place to post this, but I am looking for an alternative for the cream cheese in the oopsies. I can't eat cheese (lactose intolerant). I have tried mayonaise and a little coconut oil, but my oopsies are looking a little flat in the oven at the moment - and they have spread out in the pan. "Oops" is right.... Any tips?

    Im altso lactose intollerant and I can eat cheese, becuse there are no lactose in cheese, its gone with the wey.
  32. Anna
    Thanks Zepp
    That's really interesting. I didn't know that.

    Then I can only presume there must be something else in cheese that my body doesn't agree with. Cheese really upsets my tummy and soft cheese seems to be the worst. It also seems to give me a skin breakout
    My version of the oopsie was a flop (texture, taste was good). I will omit the coconut oil next time. I've seen versions with peanut butter and also with mayo. Will experiment with the mix.

    1. is constipation a phase in following an lchf diet?
    2. when in an lchf diet, is one allowed to take fiber supplements such as pure psyllium husks?
    Reply: #485
  35. Zepp
    1. Yes its a comon beginners problem!
    2. Yes those is the most used fiber supplements.
    3. Dont let it go to far, take some home cures, like husk, magnesium, other whole seeds like linsseeds, and fibrius veggies like asparagus.
