The Scarsdale diet's idea of reducing carbohydrates, eating plenty of oily fish and lean meat with fruit and vegetables and having a low intake of fats, salt and sweets was novel at the time and when "The Complete Scarsdale Medical Diet" was published in 1979, it became an immediate bestseller. However, the Scarsdale diet was dismissed by medical experts and is often listed as an example of a fad diet. The diet was criticized by Henry Buchwald and colleagues for "serious nutritional deficiencies". Negative effects of the diet include constipation, nausea, weakness and bad breath due to ketosis.
