The low carbohydrate Stone Age Diet was first introduced to the public in the book “Eat Fat and Grow Slim”, by Dr Mackarness. Original publications were in 1958 and 1961, then a revised edition appeared in 1975.
The originator of this low carb diet ran the first obesity and food allergy clinic in Britain. Dr Mackarness’ observations were made from the clinic, as well as other worldwide medical evidence regarding eating habits.
“Eat Fat and Grow Slim” argues that weight gain can be attributed to the body’s inability to break down carbohydrates effectively. Dietary problems began with the introduction of agriculture, leading to the conclusion that low carb diets are better.
Within the Stone Age Diet, healthy fat intake is encouraged, while sugars must be removed from the diet. Required protein is available in the forms of fresh meats, fish and poultry. Grains and dairy are also considered taboo, theories that are echoed in the more recent “Neanderthin” low carb diet plan.
Fruits and vegetables are considered “natural” or “original” foods, similar to meats. The high levels of vitamins, minerals and antioxidants found in fruit and vegetables are required for a naturally healthy diet. Nuts and legumes can also give necessary vegetable proteins, however, modern processing techniques have introduced unhealthy levels of sodium.
This low carbohydrate diet also includes arguments for and against exercise. Dr Mackarness leaves the decision for exercise up to the individual low carb diet follower.
