How ketogenic (low carb high fat) diets work

A really nice paper was just published by Paoli, Rubini, Volek and Grimaldi in the European Journal of Clinical Nutrition titled “Beyond weight loss: a review of the therapeutic uses of very-low-carbohydrate (ketogenic) diets” You won’t see a better review paper for summarizing the latest in how we think carbohydrate restriction affects various aspects of metabolic health; from weight loss to neurological issues to acne (yes acne!). A second excellent review article was also published in Nutrition Today by Volek (again!) and Phinney, the low carb gurus. This one is called “A… Read More

How do I get fat adapted and train for triathlons?

Hi Grant, I met you on the weekend at the New Zealand Society of Positive Psychology after the morning workshop when you showed a group of us around your building. I asked you, as a ‘fellow triathlete’, about your diet and exercise regime. You directed me to your blog which I read and found very interesting. I have started on the road to a LCHF diet 🙂 So far so good. I would really appreciate your advice on an exercise programme. Your current exercise programme sounded really interesting – not as grinding… Read More

Help! My husband is a high cholesterol triathlete

Hey Grant I’m a bit stuck what to do and would appreciate your opinion on something: My husband Bob is 43, weighs 80kgs, is a builder, very active (does half ironman etc) with me at triathlon club, seems to deal with work/stresses etc very well and yet every year is told that he has high cholesterol. Traditionally this would mean really watching the fats, butter etc, which we have done, but the readings never change. Obviously we need to look at trying something else but I’m not sure about the LCHF way… Read More

PS from the low carb dabbler – Part 2

Although my food diary wasn’t as complete as it could have been during the 7 day ‘low carb high fat’ experiment, and the FoodWorks software used to analyse it has its limitations, this is what it found: Most of my calories were definitely coming from fat, although according to Mikki, an even higher fat % and lower carb % would be desirable on a LCHF (or ketogenic) diet. Suggested ratios are Fat > 75%; Carbs 5-10%; Protein 5-15%. Mine were….. Of more interest to me however was the total grams of carbs… Read More

PS from the low carb dabbler – Part 1

Thanks to everyone reading and passing on this blog.  Its grown really fast and already is closing in on 10,000 hits in a little more than 6 weeks.  So thank you. Helen Kilding started editing my blogs, and as you can see after a few weeks of that she really got the blogging bug herself.  She’s also having quite a journey converting from low fat vegetarianism to a whole foods high fat diet including plenty of meats. Helen can speak for herself, and will continue to do so in this and subsequent blogs,… Read More

Will sweeteners make you fat or sick?

Now here’s a very controversial topic: aspartame and other artificial sweeteners. My conversations with (usually) men on sugar and substitutes usually go something like this: Me: ‘Have you thought about replacing your fizzy drinks with diet drinks like Coke Zero or Diet Coke?’ ‘No.’ Me: ‘Why not?’ ‘I don’t drink that shit.’ Me: ‘What do you mean?’ ‘It’s full of that artificial crap, like those sweeteners and other chemicals. They cause cancer. Diet Coke is a girls’ drink, as well.’ Me: ‘So you’d rather drink that 500 ml of Coke, which has… Read More

Final installment of the diary of a low carb dabbler – Part 5

The final day of my 7 day LCHF dabble is here. I’d love to tell you that meal 21 of 21 was a big eye fillet drenched in a creamy butter sauce served with deep fried broccoli but hey, that’s not what dabbling is all about. Poor planning , a lack of motivation to go shopping and wanting to have the same meal as my husband, meant that my last supper was, of all things, a bowl of pasta, albeit with a very oily sauce. So I’ve done it, the 7 days… Read More

Diary of a low carb dabbler – Part 4

Oh dear….maybe when you reintroduce meat in to your diet after over 20 years, you should start with a small portion, not a LCHF diet portion! Stomach ache and nausea in the middle of the night, whilst trying to feed a 3 month old, is not fun. I felt almost back to normal by morning and after some YCBNS and a lovely run/walk on the beach, all was good in the world again. Today was my first real experience of eating out as a LCHF dabbler. My usual café lunch of a… Read More

Diary of a low carb dabbler – Part 3

In the first installment of the Diary of a low carb (or LCHF dabbler), I talked about who I am (a physically active and breastfeeding pescatarian, who regularly falls off the glucose cliff) and who I want to be (a sub-3 hour marathon running Super Mum)! In the second installment I reported back on a great first 3 days. Stable blood sugar levels, enjoyable exercise, tasty meals. But on Day 4 something changed. After the usual one feed in the night, I woke up around 6.30 am, keen to go for a… Read More

Diary of a low carb dabbler – Part 2

Well after some early hiccups, I’m now 3 days in to my 7 day trial. Day 1 was Day 1 by accident really…..after having a café brunch of omelette and salad, an early afternoon snack of full fat yoghurt with nuts and seeds, and then a dinner of a beautiful piece of oily salmon with salad and just a small piece of bread, I realised that I’d possibly, accidentally, had a relatively LCHF day. So I decided to call that Day 1. I started the next day with just a small bowl… Read More
