Dr. James Hays, an endocrinologist and director of the Limestone Medical Center in Wilmington, DE, presented the results of three studies of men and women with type 2 diabetes involving very high-fat, low-carbohydrate diet at the annual meeting of the Endocrine Society. His study showed an impressive benefit in body mass index (BMI), triglycerides, HDL, LDL and HbA1c.
Patients were able to eat all the meat and cheese they wanted, but as for carbohydrates, they are restricted to eating unprocessed foods, mainly fresh fruit and vegetables. Whereas in a normal diet 60 percent of calories would come from carbohydrates and 30 percent from fat, patients in this diet were encouraged to get 50 percent of their caloric intake from fat, and just 20 percent from carbohydrates.
A whopping 90 percent of the fat content in their diets was saturated animal fat, compared with just 10 percent that was monounsaturated oil.
Dr Hays told his audience that:
Over the course of one year, the subjects achieved
# a mean decline in total cholesterol from 231 to 190 mg/dl
# LDL (the ‘bad’ cholesterol) fell from 133 to 105 mg/dl,
# HDL (the ‘good’ cholesterol) increased from 44 to 47 mg/dl.
# Triglycerides declined from 229 to 182 mg/dl.
# HbA1c, which at the start of the study averaged 3.34 percent above normal, declined to just 0.96 percent above normal
# Average weight loss was in the order of 40 pounds.
