Abstract
We previously demonstrated that a loosely
restricted 45%-carbohydrate diet led to greater
reduction in hemoglobin A1c (HbA1c) compared to
high-carbohydrate diets in outpatients with
mild type 2 diabetes (mean HbA1c level: 7.4%)
over 2 years.
To determine whether good glycemic control
can be achieved with a 30%-carbohydrate diet in
severe type 2 diabetes, 33 outpatients (15
males, 18 females, mean age: 59 yrs) with HbA1c
levels of 9.0% or above were instructed to
follow a low-carbohydrate diet (1852 kcal;
%CHO:fat:protein = 30:44:20) for 6 months in an
outpatient clinic and were followed to assess
their HbA1c levels, body mass index and doses
of antidiabetic drugs.
HbA1c levels decreased sharply from a
baseline of 10.9 +/- 1.6% to 7.8 +/- 1.5% at 3
months and to 7.4 +/- 1.4% at 6 months. Body
mass index decreased slightly from baseline
(23.8 +/- 3.3) to 6 months (23.5 +/- 3.4).
Only two patients dropped out.
No adverse effects were observed except for
mild constipation.
The number of patients on sulfonylureas
decreased from 7 at baseline to 2 at 6 months.
No patient required inpatient care or insulin
therapy.
In summary, the 30%-carbohydrate diet over 6
months led to a remarkable reduction in HbA1c
levels, even among outpatients with severe type
2 diabetes, without any insulin therapy,
hospital care or increase in sulfonylureas. The
effectiveness of the diet may be comparable to
that of insulin therapy.

COMM
ENT: I have been preaching for over 20 years
that diabetes is a disease of carbohydrate metabolism,
and that type-2 diabetes can be cured with a low-carb,
high-fat diet. By that I mean cutting calories from
carbs to around 10% of calories and increasing calories
from fats to 60% or more. Over that time, study after
study has demonstrated that this protocol works and is
safe.
The studies over this period
started to reduce carbs and increase dietary fats only
by small amounts, and we are still only at the stage in
this study above of lowering carbs to 30% and
increasing fats to 44%, so there is still some way to
go. However, studies which have cut carbs to as low as
8% and raised fat intakes to over 60% have shown that
this is entirely safe.[1]
It is possible that the
American Diabetes Association and Diabetes UK will
reverse their dietary guidelines and stop harming
diabetics - but don't hold your breath. Without
diabetics, how would they keep their jobs? Without
diabetics, they would be redundant.
