Fat adapted: Do you need carbohydrates if running on the LCHf diet?

Charles submitted his question for the Ask Prof Noakes podcast today and it has to do with explaining the Banting diet to athletes who are not following it.

Charles said he’s been asked this question by people who are against the Banting diet, and he doesn’t quite know how to answer them.

If a non-fat adapted athlete, who fuels on carbohydrate, runs out of carbs, will their body then switch to fat for fuel, or what will the body use?  Likewise, for a fat adapted person, if a fat adapted person adds carbs before a race, does their body use the carbs first and then the fat stores for fuel later?  And finally once those carbs are burnt out, will it burn fat first?

Professor Tim Noakes:  Those are great questions and what we do know is that once you become fat adapted you metabolise carbohydrate totally differently.

Does the Banting diet affect children’s development and concentration?

We’ve mentioned the book The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet by Nina Teicholz  (Buy it on Amazon here or Kalahari here) before on the Ask Prof Noakes Podcast.

Essentially what Nina Teicholz does is look at all the scientific studies around the LCHF diet and debunks many of the myths surrounding the Banting diet.

Today’s question is linked to the subject of scientific studies. Jodie submitted her question and she wanted to know if there have been any studies done around the long term development effects on children eating a Banting diet as well as on their concentration capacity.

Professor Noakes:  Unfortunately not.  We do have some data on children who are epileptic and were put on the diet.  The diet was developed for children who are epileptic and it almost cures the epilepsy.  So they can reduce their medication dramatically

The Banting Diet: Making sure your child’s health comes first

On the LCHF diet or Banting diet does the amount of carbohydrate you recommend for adults on the Banting diet be the same as for children.

Basically what this person is saying is, she gives her child Weetabix for breakfast with full cream milk.  They’re working the sugar out of the child’s diet progressively.  They then pack a Banting friendly lunch for school, which includes a bit of fruit, and then obviously a Banting friendly dinner.  This parent wants to know if she is on the right track here?

Professor Tim Noakes:  Yes, absolutely.  It sounds like she’s cut the carbs to about 250g.  It looks to me, there’s still slightly more than I would like, because you’ve got to watch out for the fruit.  When you are eating fruit you rack up carbohydrates very quickly. Each portion size is probably between 25 to 50g.

So I think she’s doing a great job.  The key is that you don’t want to get the carbohydrate addiction or the sugar addiction.  If she’s cutting the sugar she’s fine.

The three mistakes parents make when feeding their kids a LCHF Diet

It is easy as a parent to fall into the convenience trap when it comes to feeding our children. Let’s be honest, eating a LCHF diet does take a little bit of planning.

With our busy lifestyles sometimes things pop up and we are left stranded when it comes to not having a meal planned or prepared. It is often too easy to revert processed convenience food or fast food as a quick alternative to a healthy LCHF diet.

Today I ask Prof Tim Noakes what are the most common mistakes he sees parents making when introducing their children and their entire family onto the LCHF or Banting diet?

Prof Tim Noakes:  That’s a good question because I really don’t know specifically what LCHF diet mistakes are being made by parents with their children. What I mean is I obviously I focus more on adults because those are the patients, those are the people I deal with.

Teaching multiple truths: Is there only one correct food pyramid?

David Rowe sent us an email this week. His entire family buy into the benefits of the LCHF Diet. He is however sitting with a very difficult situation.

His daughter, who is still in school, is being taught one thing at home about the LCHF diet but is being taught about the conventional food pyramid at school, but doesn’t believe any of it. She will obviously need to write exams on it and unless she tows the line she will not pass the exam.

What do you suggest David and his daughter do in this situation?

Professor Tim Noakes: To answer David’s quesiton, you know, I am occasionally invited to lecture the medical students, and at the end of the lecture the students come up and say to me, Prof, if we say what you say we’re going fail our exams.  That is a failure of education.  Because that suggests that there is only one answer.

The reality is, in education you have to tell people the whole truth.  And if there are two models, or two explanations, you have to give both.  And you say listen, this is the story.  For example, the whole story about fat.

Banting and Conventional thinking: What’s changed with the LCHF Diet?

On today’s Ask Prof Noakes Podcast we take a look at the ‘traditional’ thinking on nutrition that is being taught in schools currently as opposed to the one that describes the LCHF or Banting diet. We received an email from a concerned parent.

They are having a problem trying to explain the benefits of the Banting diet to their child.  She says their son has a teacher at school who is dead against the Banting way of life.  This child’s also had years of people telling him at school that, that he shouldn’t be eating fat because fat is bad for you.

Now the parents are giving him fat.  He’s a bit confused and this parent is trying to make things a bit easier to understand for the child who is 13 years old.  What’s the best way to explain the Banting of LCHF diet to kids?

Professor Tim Noakes: That’s a difficult one.  I think that, that the way I explain it, is knowledge changes.  When I give my talks and what I’ve written in Real Meal Revolution and elsewhere, is that we changed our diet in 1977. It changed on the basis of commercial reasons because big business wanted to promote grain sales in the United States of America.

Banting and supplements: Do kids need vitamins if eating a LCHF diet?

We’ve been chatting quite a bit about children on the Banting diet over the last few days and today’s question is once again related to feeding your kids a LCHF diet.

If you are following the Banting diet will your child become deficient in any nutrients that they need to develop? On the LCHF diet would you suggest any form of vitamin supplementation for your children?

Prof Tim Noakes: Okay, so let’s say you thought Tim Noakes’ Banting diet was all meat, and you just ate meat, that wouldn’t be a good idea because that wouldn’t be a nutrient dense diet.

We want our diet to be full of nutrients.  The three foods that are full of the most nutrients are simply eggs, sardines and liver.  If you’re getting those three foods on a regular basis in your diet, you will not be nutrient deficient, because they are packed with nutrients.

Children on the LCHF Diet: Is it safe for kids to be Banting?

People are always very hesitant to change their way of thinking and there’s obviously a lot of concern around the LCHF diet lifestyle because people are really stuck in the old mind set of eating.

Julia got in touch with us and she wanted to know if there are any precautions parents should take or things they should be aware of when introducing their kids to the Banting Diet?

How  does changing to the Banting diet affect kids, and is Banting safe for her kids?

Prof Tim Noakes:  That’s a great question, as you know I was reported to the Health Professions Council of South Africa for suggesting that you should wean your children onto the Banting diet.

By that I mean the green list in the Real Meal Revolution. I would encourage anyone to look at the green list and tell me what’s wrong with that food.  It’s really good food for anyone of any age. So I don’t know where this criticism is coming from.

Is Banting safe for kids?

Fortunately, there’s a paper out this week, showing that children who are weaned onto meat, specifically they said meat and not other proteins coming in from cereals, for example.

They grew more, they were taller and they were less fat at the end of the study, which was a year or two. I found it very interesting, because we know that when cereals and grains were introduced into the food supply 12 000 years ago, humans got smaller, and we’ve only caught up now, can you believe it?

Children’s Lunch Boxes on the LCHF diet: What should kids eat?

Today on the Ask Prof Noakes Podcast we chat about the LCHF Diet and what you should be putting in your kid’s lunch boxes. We answer Janet’s question today about whether or not you should include more carbohydrate in children’s lunch boxes (as opposed to what we would eat ourselves)?

Janet’s question read as follows: ‘I have a pre-teen son and he just doesn’t seem to stop eating and I’m wondering if you can advise in this regard. His weight is perfect, and he is quite a busy sporty child. What sort of food should he be eating?’

Prof Tim Noakes: I think that if they are continually hungry, it is because they are getting too little protein and fat in their diet. I would suspect that’s a high carbohydrate diet.

We find that with most of the children we deal with, if we can get them to eat a high fat-high protein breakfast so that they really eat a lot, they generally don’t get hungry until 2 or 3 o clock in the afternoon.

How to get over your bread addiction on the LCHF diet

Many people struggle on the LCHF diet when it comes to cutting bread out of their diet. It is also difficult if you want your children to follow a LCHF diet, particularly when it comes to what you can pack in their lunch boxes for school.

Today’s question on the Ask Prof Noakes Podcast was submitted by Julia and she says that her family has recently taken to the LCHF diet or Banting lifestyle.  She is finding that her older children ( a 6year old girl and 12 year old boy) are struggling with the new LCHF diet bread and are struggling to let go “traditional” bread.

Is there anything you can suggest to help me help them with this transition?

Prof Time Noakes: I think it is really important to cut the wheat, because I think wheat will be shown to be one of the more damaging foods that we eat. And it is so prevalent particularly when you’re eating 5 or 6 slices of bread a day (as I used to), that’s a huge wheat load.

It is the gluten in bread that is so dangerous

For those of us that cannot metabolise it, and I think that’s a good proportion of the population, it’s not healthy. You see the problem why we are addicted to bread with wheat is because they rise because there is gluten present. Of course it also soaks up the butter, and everything you put on the bread so up nicely and that makes it so delicious.

That is the problem though. The very gluten that makes it so attractive as a food, is what is killing us or what is harming our health. As soon as you take gluten out of your diet you are just never going to get the same type of bread.
