We are recruiting for a ketogenic diet study

We are inviting interested people to participate in a research study about ketogenic diets. The study “The Effects of Two Different Supplemental Oils on Keto-Adaptation and Symptoms of Carbohydrate Withdrawal” seeks to help us better understand the effects of different food oils on achieving nutritional ketosis, and on symptoms of carbohydrate withdrawal (know as ‘Keto-Flu’).

We are seeking non-obese, non-diabetic people aged between 30 and 50 years of age who have not previously followed a ketogenic diet and who are not current or former clients of either the lead researcher Cliff Harvey or Secondary Supervisor Mikki Williden.

If you decide to participate in this study you will follow a ketogenic diet prepared by Cliff Harvey for 20 days and will record ketone levels (by way of a daily blood-prick test), along with a daily questionnaire and diary entry to evaluate a range of physical and psychological indicators of health.

This study is completely voluntary and you may withdraw at any time. If you’d like to participate please go to www.ketodietstudy.com

I am Grant Schofield, Professor of Public Health at Auckland University of Technology and director of the university's Human Potential Centre (HPC) located at the Millennium Campus in Auckland, New Zealand. My research and teaching interests are in wellbeing and chronic disease prevention especially reducing the risk and eventual mortality and morbidity from obesity, cardiovascular disease, and diabetes. I live by the motto "be the best you can be" and have a strong commitment to peak performance in which I also do consulting work. I’ve been interested in human health and performance for my whole career. I started in psychology, went into sport and exercise psychology, then into public health, especially physical activity, then obesity. There have been some twists and turns along the way, which are the reasons for why I do what I do – you can read about those in my first blog entry. I want to know how we can be the best we can be. This crosses disciplines such as biology, medicine, pubic health, and productivity management. The cornerstones are nutrition, exercise, sleep, neuroscience, psychology and wellbeing. In my blog, I cover these topics under the broad heading of the Science of Human Potential.

  1. Have submitted my application. Just older than 50 but would so love to participate! have been wanting to do this for a while and just don’t have know all to do it on my own. Please please please 🙂

  2. Unfortunately I am out of the age range on this occasion as I am 26yrs of age, but if that should change or any further studies take place in the future I’d be happy to help.

    Kind regards,
    Sarah.

  3. Hello. I just wanted to make an observation about the length of your study and the time taken for ketosis transition. I am a healthy 55 year old (well I will be 55 tomorrow on my birthday and until recently have been healthy). I have recently tried a ketogenic diet. I read a number of books about it and was convinced it was a good thing to do. I read the best way to go about it. I was at 68kg and over about 7 weeks lost 6kg of stomach fat. I was not hungry and eating organic and well. I had bad ‘keto flu’ at the beginning and had a constant pressure in my head and although the other side effects abated after 3 weeks but then things suddenly started to go wrong. At about 7 weeks in, my blood pressure suddenly destabilised and was swinging high and low and my heart rate went really high. I had a terrible pressure in my head and then got a horrendous migraine. There was a constant ‘whooshing in my ears and I could hear my heart beat. I thought I was having a heart attack or stroke. My doctor did all possible blood tests and said I came back hitting normal on all tests. So my cholesterol, triglycerides, HCL, LDL, minerals, kidney and liver function all came back as fine. But I couldn’t stay on the very low carb any longer. I gently introduced more starches such as rice and root vegetables back into my diet and my blood pressure stabilised and after a couple of weeks the whooshing in my head eased off. I’ve kept upping the carbs over the past 2 weeks until I felt better and have now settled on 35-40% carbs, 15-18% protein and 40-45% fat on an average of around 1800 calories a day. I’ve finally managed to stabilise and my heart rate is gradually returning to normal.
    I have since read that the raised heart rate and palpitations is a common side effect of very low carb eating. It appears as a topic on lots of LCHF forums and is often attributed to lack of salt but I know I was taking that and my electrolyte levels were fine. So I wanted to know if you know of anyone having a similar issue with low carb dieting? And if perhaps low carb eating is not for everyone? I must admit to being disappointed because I was really bought over to the idea. However it does make me wonder if a study lasting just 3 weeks is long enough as it took several weeks beyond that for my issues to manifest themselves.

    1. Hi Shuna. I’ve had similar to you in some areas but not others, and perhaps not so severe. No headaches but it’s nice to know someone else gets that whooshing in the ears – it always feels weird. Intermittent periods where I get very light headed, Worst are the hot flushes, and being a bloke, I’ve gained a bit of an understanding of what some middle aged women have to cope with. Not pleasant. Just had overseas holiday and ate like a big pig, and just back to sensible eating now. I usually get a couple of days of lethargy and then I’m ready to go, so will be interested to see how I adapt after falling off the wagon. It was a big fall 🙂
