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.
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 dairy, but is this recommendation actually justified by evidence? Or is it simply outdated?
Milk and dairy are commonly avoided by people seeking health but is the recommendation to eliminate dairy justified?
Fatigue is a common presenting symptom and unfortunately, its treatment is wrapped in woo! This article presents evidence-backed interventions to help you recover from fatigue
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?
Recent articles have suggested that higher fat intakes are responsible for ‘keto-crotch’. Does this study support that contention?
Ketogenic diets and ketones themselves offer a promising treatment option for neurodegenerative disorders and cognitive decline.
The ketogenic diet is often touted as a ‘cure’ for cancer. But is this justified? Could there be risk from using a keto-diet for cancer?
Key Findings HAES results in significant and lasting benefits to self-esteem, body image, hunger cues, and cognitive restraint.These results are similar to social support programsHAES does not result in substantive benefits to physical health.A combined approach, focused on psycho-social and physical indicators of health is likely to the best approach. Traditional weight loss methods are based primarily on a medical model which treats obesity as a disease requiring diet, exercise, or pharmaceutical intervention. Conversely, the increasingly popular ‘Health At Every Size’ (HAES) movement believes that “individuals who are overweight and obese want to exercise and eat healthy foods, and they are capable of doing so when barriers are removed”.1 The Health At Every Size® Principles are: Weight Inclusivity: Accept and respect the inherent diversity of body shapes and sizes and reject the idealizing or pathologising of specific weights.Health Enhancement: Support health policies that improve and equalize access to information and services, and personal practices that improve human well-being, including attention to individual physical, economic, social, spiritual, emotional, and other needs.Respectful Care: Acknowledge our biases, and work to end weight discrimination, weight stigma, and weight bias. Provide information and services from an understanding that socio-economic status, race, gender, sexual orientation, age, and other identities impact weight stigma and support environments that address these inequities.Eating for Well-being: Promote flexible, individualized eating based on hunger, satiety, nutritional needs, and pleasure, rather than any externally regulated eating plan focused on weight control.Life-Enhancing Movement: Support physical activities that allow people of all sizes, abilities, and interests to…
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.
Key Findings Carbohydrate restriction does not result in alterations of ovulation, menses, or other indicators of women’s hormonal health. Low-carbohydrate diets have demonstrated positive benefits to women’s hormonal health. Extreme calorie restriction is likely to affect women’s hormonal balance and health. Those women who are leaner and exercise more are at greater risk of negative effects from excessive or prolonged energy restriction. 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 indicators of hormonal health. Does This Claim Stack Up? There is no evidence that 200 g per day is required to preserve markers of female hormone balance. In fact, the most commonly cited study to support the idea that there is a minimum requirement for carbohydrate showed no such thing.
