CR above all

[Guest guest]

Hi All,

It might be said: " CR über alles. Well, above macromolecule content of foods

may be

a preferred context.

The not yet in Medline pdf-available below paper below suggests that it may be

so.

Although the subjects were obese, who else would adhere to such a study except

maybe

a strange lot of wild-eyed lunatics called CRers?

Pluses seemed to be that the study was a randomized control, it was in humans,

it

was in healthy subjects, fats were 1:1:1 for saturation status, protein level

was

the same for all and the level of cholesterol in the diets was the same.

Results seemed to significantly and not significantly favor the low glycemic

index

and load diet and the lower fat diet, for that matter.

Reduced Glycemic Index and Glycemic Load Diets Do Not Increase the Effects of

Energy

Restriction on Weight Loss and Insulin Sensitivity in Obese Men and Women

J Nutr. 2005 Oct;135(10):2387-2391.

ABSTRACT

Reducing the dietary glycemic load and the glycemic index was proposed as a

novel

approach to weight reduction. A parallel-design, randomized 12-wk controlled

feeding

trial with a 24-wk follow-up phase was conducted to test the hypothesis that a

hypocaloric diet designed to reduce the glycemic load and the glycemic index

would

result in greater sustained weight loss than other hypocaloric diets. Obese

subjects

(n = 29) were randomly assigned to 1 of 3 diets providing 3138 kJ less than

estimated energy needs: high glycemic index (HGI), low glycemic index (LGI), or

high

fat (HF). For the first 12 wk, all food was provided to subjects (feeding

phase).

Subjects (n = 22) were instructed to follow the assigned diet for 24 additional

weeks (free-living phase). Total body weight was obtained and body composition

was

assessed by skinfold measurements. Insulin sensitivity was assessed by the

homeostasis model (HOMA). At 12 wk, weight changes from baseline were

significant in

all groups but not different among groups (–9.3±1.3 kg for the HGI diet,

–9.9±1.4 kg

for the LGI diet, and –8.4±1.5 kg for the HF diet). All groups improved in

insulin

sensitivity at the end of the feeding phase of the study. During the free-living

phase, all groups maintained their initial weight loss and their improved

insulin

sensitivity. Weight loss and improved insulin sensitivity scores were

independent of

diet composition. In summary, lowering the glycemic load and glycemic index of

weight reduction diets does not provide any added benefit to energy restriction

in

promoting weight loss in obese subjects.

From Al's post:

" In summary, lowering the glycemic load and glycemic index of

I think this is true. Calories above all are king when it comes to

weight loss.

But, we can't forget that we are human beings with free will and

Krispy Kremes at every turn. Satiety is a big factor, as eating

low-glycemic foods or higher-protein foods can make you feel

full/satisfied for longer periods of time, and this helps a person who

is not under strict outside dietary control to consume fewer calories.

I think we've seen a number of studies lately that illustrate this.
