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.

Why Keto?

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!)

What is ‘benevolent pseudo-diabetes’? (And why it is important)

Some animal studies have suggested that a keto diet can result in insulin resistance and this is supported by some glucose tolerance challenges in humans. But is this phenomenon all that it seems, or could this actually be a healthy adaptation to a low-carb diet?
