Why can't food without a label be nourishing? 
We can all be an agent for change.

Meet Ævar Austfjörð, butcher, cook, and soon a farmer!

Ævar was born in the small town of Húsavík in northern Iceland.  He lived there until he moved away to learn to be a butcher. After 10 years or so, he switched to cooking. He worked mostly in steakhouses until he got into hospital cooking along with studying "special needs cooking." Ævar is qualified as a diet cook. Ævar got into the low carb living in 2012 following a stroke when he was only offered pills to recover but he decided to do his own research.

Ævar is married to Ása Sif and they have 4 children, two grandchildren, and two dogs. Soon they will have a few cattle chickens and goats!

"It's not about the science."

Belinda Fettke is a former Registered Nurse, photographer and the proud co-founder of 'Nutrition For Life' in Launceston which provides medically based nutritional care around Tasmania and Australia. 

Belinda is also a staunch supporter of the health benefits of Low Carb, Healthy Fat eating and in recent years has taken a more central role in advocating LCHF following the investigation of her husband, Dr. Gary Fettke, by the Australian Health Practitioner Regulation Agency (AHPRA). The investigation focused on Gary’s qualifications to give nutritional advice.

This investigation (which lasted for more than two years) resulted in Gary being issued a ‘caution’ and being advised; ”In particular, that he does not provide specific advice or recommendations on the subject of nutrition and how it relates to the management of diabetes or the treatment and/or prevention of cancer.” Gary was later cleared of all charges and issued a formal apology from AHPRA.

Eat LIke a Pig

Eric P. Berg grew up on a commercial cattle operation just outside of Kindred, ND. He received his BS degrees from NDSU in Animal Science and Ag Education and his MS degree from NDSU in Animal Science. He got his PhD degree from Purdue University., Postdoctoral fellowship at Texas A&M University. He joined the North Dakota State University Animal Sciences Department faculty in 2006.

Dr. Berg is currently researching the role of meat in the human diet as a means to optimize health and well being.  He is using female pigs as a biomedical model for human females. The National Institute of Health notes that pigs are the best model for studying how food influences physiology, as pigs and humans have the same physiological response to food - both are simple stomached omnivores. 

Dr. Berg has studied caloric intake, accumulation of fat, and cholesterol levels in pigs fed corn/soy based diets vs ground beef diets. Despite consuming more total feed/food and more calories, the ground beef fed gilts gained less body weight and deposited less subcutaneous fat over the 84 days on test.

Animal and human diets must contain essential fatty acids and essential amino acids; both of which are in a highly bio-available form in red meat. Lean high quality red mean can contribute to a low glycemic diet and provide essential proteins, and thus contribute to a healthy diet. Increasing consumer knowledge and awareness of the benefits will help the North Dakota livestock industry and human health.

“Once you see the benefits of LCHF, you cannot unsee them.”

Dr. Gary Fettke is an Orthopaedic Surgeon practising in Launceston, Tasmania, Australia.

He has a major interest in the preventative medicine and encourages his patients to lose weight before undergoing surgery. Although his speciality is surgery, Gary believes it is much better to help people avoid surgery by taking preventative measures, which often involves primarily altering the diet. He is an advocate of a Low Carbohydrate Healthy Fat (LCHF) lifestyle for the health benefits.

He was “a fat kid” and has experienced ‘too many’ other health issues until changing his diet and lifestyle. He has concerns that as we get older the health systems will be under significant stress from financial and health burden aspects. It is simply unsustainable – a train crash in evolution.

In recent years Gary has focussed on the role of diet in the development of diabetes, obesity and cancer. He has been speaking out internationally on the combined role of sugar, fructose, refined carbohydrates and polyunsaturated oils linking together to be behind inflammation and modern disease.

Gary remains committed to understanding the central role of nutrition in everything ranging from our health issues to its role in influencing education, the environmental impact, economics, politics and belief systems.

He has incurred the wrath of regulatory bodies for his stand on public health, but he and his wife, Belinda, remain active defending the benefits of low carb healthy fat living. Their ongoing work has uncovered the vested interests and ideologies shaping nutritional guidelines at an international level.
