Issue 5 | Volume 1 | October 2019 In this issue: This month we have a special ‘Food Fight’ issue that focusses on the low-carb vs high-carb debate! Feature article Should you choose high or low-carb? There is a seemingly endless debate between advocates of high and low-carb diets. In this article, Cliff Harvey PhD delves into the research, including that if he and his team, to show you what the science says about who is best suited to higher- or lower-carb diets. Read the article here In the literature What is ‘benevolent pseudo-diabetes’? There has been some suggestion that low-carb and keto diets can cause insulin resistance and this is supported by some animal studies and human clinical findings. However, low-carb also treats metabolic syndrome and insulin resistance. So, what’s going on here? Could the insulin resistance observed in studies actually be of benefit to people following a low-carb diet? Read the article here Another nail in the saturated fat & heart disease hypothesis? The idea that total fat intake and saturated fat in the diet are linked to heart disease persists. Many studies and reviews of the literature have refuted this hypothesis and in this review of a recent meta-analysis, Cliff examines the faltering evidence for the link between saturated fat and heart disease. Read the article here The ‘big fat debate’ over low-carb or low-fat diets and diabetes Recent media articles have highlighted the debate between low-carb and low-fat diets for treating diabetes. In this article, Cliff…
The idea that total and saturated fat intake is a risk factor for heart disease still persists. In this review, Cliff examines a recent meta-analysis that casts further doubt on this.
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?
There is an endless debate between proponents of high-carb vs low-carb diets. So, how can you decide which is best for you? In this article, Cliff Harvey PhD summarises the research to show how you can determine what’s best for your body.

The latest Carb-Appropriate Research Review is all about dairy! Find out the latest research on the health effects of dairy, whether it is pro- or anti-inflammatory, PLUS the low- vs full-fat debate, and all about A1 vs A2 protein.
There is concern about the insulin stimulating effects of dairy. In this study, the effect on insulin and blood glucose homeostasis of increased dairy intake was explored.
A1 protein from milk has been suggested as a risk factor for health, while A2 is promoted as a health food that avoids these risks. Find out what the research tells us about A1 vs A2.
Dairy is commonly considered inflammation causing. But is this justified? For whom is dairy inflammatory…and for whom is it not?
Low-fat dairy is recommended in dietary guidelines over natural, full-fat diary, but is this recommendation actually justified by evidence? Or is it simply outdated?
Bone broth has become a popular food-supplement but does it really provide health or performance benefits?
Issue 3 | Volume 1 | August 2019 In this issue: Articles Is the Ketogenic Diet Really a Cure for Cancer? The ketogenic diet is touted as a ‘cure’ for cancer with claims that it effectively starves cancer cells of fuel. But do these claims stack up? Can the Ketogenic Diet and Ketones Improve Brain Health? The ketogenic diet shows promise for improving brain health and reducing neurodegeneration. Find out what the science says in this special report. Research reviews and commentary Does Increased Fat in the Diet Cause ‘Keto-Crotch’? This study is often used to support the idea that a ketogenic diet results in less-than-pleasant odours on a keto diet! But does this study really show that?… Or something else entirely? Are Low-Carb Diets Deficient in Essential Nutrients? It’s commonly claimed that low-carb and keto diets are lacking in essential micronutrients. In this study by Caryn Zinn and colleagues of AUT University, they compare a healthy low-carb diet to a standard western-style diet. Can Ketogenic Diets Improve the Structure of Key Brain Cells Emering reserach is shwoing that ketogenic diets can aid supportive ‘glial cells’ of the brain. Find out what this means in this short review of a recent study that has hit the headlines. World Health Organisation’s Recommendations on Saturated Fat Are Out of Date… Recent expert reports have again challenged the outdated idea that saturated fat is a significant, independent impactor of mortality.

Ketogenic diets might help to improve the function of important supportive brain cells.
A common criticism of low-carb and keto diets is that they do not supply adequate amounts of essential nutrients, but is this justified?
Ketogenic diets and ketones themselves offer a promising treatment option for neurodegenerative disorders and cognitive decline.
Over 7 million copies of Eat Right for Your Type have been sold and many people follow a ‘blood type diet’. But does it stand up to scientific scrutiny?
Issue 2 | Volume 1 | July 2019 In this issue: Articles Do Low Carbohydrate Diets Negatively Affect Female Hormone Balance? Many people think that low-carb diets are negative for female hormone balance, menstrual cycles, and ovulation. But does this stand up to scientific scrutiny? Can You Be ‘Healthy at Every Size’? ‘Health At Every Size’ (HAES) has become a very popular ‘anti-diet’ movement, and while it’s goals a laudable and it results in benefits, can you actually be healthy at every or any size? Research reviews and commentary How reliable is the statistical evidence for limiting saturated fat intake? Most reviews and meta-analyses show no effect of saturated fat on mortality but the influential Hooper meta-analysis of 2015 suggested increased risk of death from saturated fat in the diet. But was this finding reliable? In a new study, Simon Thornley and colleagues cast doubt on the findings of the Hooper analysis. Association of changes in red meat consumption with total and cause-specific mortality among US women and men: two prospective cohort studies A recent study has been highly promoted in the media as another ‘nail in the coffin’ for red meat, suggesting an increased risk of death from eating red meat. But was this effect really shown? From the media 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…
Most meta-analyses do not support the idea that saturated fat is a cause of heart disease but the 2015 meta-analysis by Hooper and colleagues suggested that saturated fat increased mortality. But was this study reliable? In a new analysis, Thornley et al., cast doubt on the reliability of this finding.

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 how people feel! Subjective perceptions of people on a keto-diet We analysed this in a qualitative study. We identified our participants subjective mood and experiences related to the ketogenic diet from daily diary entries and focus group findings. Read more & listen to the audio below
