Keto with Cliff
Cliff Harvey has been working with clients to optimise ketogenic and low-carbohydrate diets as part of his philosophy of ‘carbohydrate appropriate’ (finding the right carb intake for you) for well over twenty years.
His Master’s degree research focussed on ‘keto-flu’ and he published the first papers on this along with the first review of ketogenic supplements along with a randomised controlled trial on the use of medium chain triglycerides to improve time to ketosis and reduce keto-flu symptoms. He also, with his colleagues, performed the first qualitative study of the ‘lived experrience’ of people following a ketogenic diet.
Cliff’s Doctoral research continued to delve into ketosis and keto-flu in different types of low-carb and ketogenic diets.

Ketogenic diets and ketones have been shown to:
- Increase fat-loss vs a low-fat, high-carb diet
- Improve brain-health and reduce neurodegeneration
- Aid recovery from brain injury and concussion
- Reduce markers of future health risk and improve metabolic syndrome and diabetes
- Reduce inflammation and oxidation
- Improve anxiety and provide possible benefits in depression and bipolar disorder
What is a Ketogenic Diet?
A (good!) ketogenic diet is very low in carbohydrate, moderate to high in protein and moderate to very-high in fat. Basically, by restricting carbohydrate, the body produces more ‘ketone bodies’ to help fuel the body and the brain and central nervous system (which usually rely on glucose [sugar]).
What are 'Ketones'
‘Ketones’ refers to ‘ketone bodies’. These are chemicals the body produces all the time but in tiny amounts. When there is not enough carbohydrate to fuel the brain and nervous system, the body ramps up its production of these these fuels; beta-hydroxybutyrate, acetoacetate, and acetone.
Ketones can also be increased in the body by supplementation. Medium chain triglycerides can boost ketone production, while exogenous ketones provide BOHB directly to the body.

Why study Keto-Mastery with me?
Let’s face it, everyone’s on the keto bandwagon now. From former high-carb devotees, to Paleo and Primal experts…
But if you study with me, you’re getting 22 years+ of practical experience applying, prescribing, and studying ketogenic diets be and keto supplementation. Heck, I even did my Master’s and PhD in keto!
In Keto-Mastery, you’ll learn what ketogenic diets, ketones, and ketosis are; how to apply them; for whom keto is best (and worst) for; and the evidence behind the use of keto for a range of conditions.
All this is delivered online so you can study at your own pace and is backed by support from the team at Holistic Performance Nutrition (and me!)

A common claim currently doing the rounds is that a low-carb or keto-diet will negatively affect either ‘female hormone balance’, menstrual cycles, or ovulation. It is claimed that there is a minimum amount of carbohydrate (i.e. 200 g per day) required to preserve hormone status and ovulation, along with other…...
Rebuttal to the Physician’s Committee for Responsible Medicine article: “Keto Diet Is Dangerous for Veterans with Diabetes”
A recent article by vegan advocacy group PCRM has attacked using low-carb for veterans with diabetes. In this article, researcher Cliff Harvey provides a rebuttal to the PCRM arguments against LCHF for diabetes.
Cliff talks with former pro bodybuilder and entrepreneur, Toney ‘the X-man’ Freeman.
A Summary of Our Research: How did people ‘feel’ on a keto diet? Very little research has been conducted on people’s subjective experiences of diet. The study of this is incredibly important because if we are to properly understand diet and prescribe, based on holistic effects, we need to know…...
A lot of people freak out about protein when following a ketogenic diet. There is an idea that eating a high, or even moderate protein diet, will result in large amounts of glucose creation from amino acids in protein (gluconeogenesis). However, this idea is unfounded and there are significant benefits
