Mackarness publishes a low carb book





Eat Fat and Grow Slim

Richard Mackarness


Important Text:

The Author, Richard Mackarness, was the doctor who ran Britain's first obesity and food allergy clinic. The book merges anecdotal observations from this clinic with a comprehensive review of all medical evidence throughout the world up to the mid-1970s. In the 1975 edition, this includes a historical analysis of diets from Harvey-Banting to Robert Atkins and Herman Taller, and features the work of Blake Donaldson, Vilhjalmur Stefansson and Alfred Pennington, who all promoted an Inuit-style meat-only diet. Mackarness extols the virtues of Pemmican, discusses food allergies, examines carbohydrate addiction and touches on related psychology.

Mackarness's philosophy has three main features:-

  • A person's metabolism falls into one of two distinctive types, the constant-weight always-slim type, and the fatten-easily type.

  • Weight gained by people in the latter group is due to an inability to break down carbohydrates fully because of a metabolic defect, and not as the public at large believe, because of weak-willed gluttony.

  • Man's problems with obesity began 8,000 years ago, with the advent of cereal planting. For 4 million years before that, man was a hunter who survived by killing and eating meat, which has led to complete biological adaptation to a meat diet, but not to a cereal diet, because it is too recent.

Weight Control
Fat is a term used to describe a group of compounds known as lipids, which are organic molecules made up of carbon, hydrogen, and oxygen atoms. Fats are an essential part of our diet and play important roles in our bodies. Animal fats with low linoleic and arachidonic acids are preferred.
Carnivore Diet
The carnivore diet involves eating only animal products such as meat, fish, dairy, eggs, marrow, meat broths, organs. There are little to no plants in the diet.
