I paid $500 to get the latest information on medical science.
Low-carbohydrate diets —
Proponents
of low-carbohydrate diets have argued that the increasing obesity
epidemic may be in part due to low-fat, high-carbohydrate diets.
But
this may be dependent upon the type of carbohydrates that are eaten,
such as energy dense snacks and sugar or high fructose containing
beverages.
The carbohydrate content of the diet is an important
determinant of
short-term (less than two weeks) weight loss.
Low-
(60 to
130 grams of carbohydrates) and
very-low-carbohydrate diets (0 to less than 60 grams)
<60 grams="" span=""> have been popular for many years [
20].
Restriction of carbohydrates leads to
glycogen mobilization
and,
if carbohydrate intake is less than 50 g/day, ketosis will develop.
Rapid weight loss occurs, primarily due to
1-
glycogen breakdown and
2-fluid loss
rather than fat loss.
Low-
and very-low-carbohydrate diets are more effective for short-term
weight loss than low-fat diets,
although probably not for long-term
weight loss.
A meta-analysis of five trials found that the difference in
weight loss at six months, favoring the low-carbohydrate over low-fat
diet,
was not sustained at 12 months [
27]. (See
'Choice of diet' below.)
I looked up this (27)reference and found this chart:
Then I looked up the original Brehm trial which went out to 2 years:
I then went to a more recent head to head 2 year Shai Trial:
I must say I don't think I am getting my $500 worth of UP TO DATE material.
Back to UP TO DATE article:
Low-carbohydrate
diets may have
some other beneficial effects with regard to
1- risk of
developing type 2 diabetes mellitus,
2- coronary heart disease, and
3-some
cancers,
particularly if attention is paid to the type as well as the
quantity of carbohydrate.
A low-carbohydrate diet can be
implemented in
two ways,
either by
1-reducing the total amount of carbohydrate or by
2- consuming foods with a lower glycemic index or glycemic load (
table 3).
Glycemic index and load are reviewed separately.
(See
"Dietary carbohydrates", section on 'Glycemic index'.)
If
a low-carbohydrate diet is chosen,
healthy choices for fat (mono- and
polyunsaturated fats) and protein (fish, nuts, legumes, and poultry)
should be encouraged because of the association between saturated fat
intake and risk of coronary heart disease.
During 26 years of follow-up
of women in the
Nurses' Health Study and
20 yrs of follow-up of men in
the
Health Professionals’ Follow-up Study,
low carbohydrate diets in
the highest versus lowest decile for vegetable proteins and fat
were
associated with
1-
lower all-cause mortality and
2-
cardiovascular mortality [
28].
In contrast, low-carbohydrate diets in the highest versus lowest decile
for animal protein and fat were associated with
1-
higher all-cause and
2-
cardiovascular
mortality.

"Dietary fat" and
"Overview of primary prevention of coronary heart disease and stroke", section on 'Healthy diet'.)
ADA guideline 2013
Jackie
Boucher, MS, RD, LD, CDE, Vice President for Education, Minneapolis
Heart Institute Foundation, noted that the scientific evidence is still
limited related to various eating patterns and their impact on health
outcomes in individuals with diabetes. Current evidence does not
strongly support one eating pattern over another. “Whether you prefer a
Mediterranean, vegetarian or lower-carbohydrate
eating plan is less important than finding an eating pattern that fits
your food preferences and lifestyle, can be consistently followed and
that provides you with the nutrition you need for good health,” she
said.
In choosing an appropriate eating plan, people with diabetes should
be sure to consider individual metabolic goals, such as their glucose and lipid levels and blood pressure, the statement notes.
The new guidelines also note that there is no conclusive evidence of
an ideal amount of carbohydrate intake for people with diabetes.
However, the authors suggest that whatever carbohydrates are eaten
should come from vegetables, whole grains, fruits, legumes and dairy
products, over other sources that contain added fats, sugar
or sodium. Likewise the evidence remains inconclusive for an ideal
amount of total fat intake. Fat quality (eating monounsaturated and
polyunsaturated fats and avoiding trans fats and saturated fats) appears
to be more important than quantity, the authors note. Although
individuals working to manage their weight should still eat even good
fats in moderation.
