Low Carbohydrate vs. High Carbohydrate

Difference Between Low Carbohydrate And High Carbohydrate

Lots of studies were carried out to investigate whether different fat content in a reduced calorie diet could decrease insulin resistance that can prevent type 2 diabetes. High fat and Low carbohydrate diet is definitely an alternative but this can cause an increase in fat and can effect the insulin resistance of the body which later nullifies the benefits of weight loss.

Method:

The study compared a low fat diet (20% fat, 60% carbohydrate) with a low-carbohydrate diet (60% fat, 20% carbohydrate).  As a result weight loss and insulin sensitivity were investigated in 24 overweight / obese individuals. The study lasted 8 weeks. All foods were weighed, distributed, and the intake was estimated to generate a deficit of 500kcal/dag. Insulin production and insulin secretion were investigated. Body Composition and vascular examination were conducted.

Results:

* Significant weight loss in both the groups was noticed.

* Peripheral glucose uptake increased in people examined of both the groups and the inhibition of endogenous glucose production was also similar between the two groups.

* Insulin production decreased due to weight loss, without any difference in between both the groups.

* The change in arterial vascular stiffness, was significantly different between two diet plans (P = 0.04). This means a considerable reduction of Augmentation Index was there to be seen for a low-fat diet as compared to a non-significant increase in the low-carbohydrate group. Thus, a poorer prognosis for LCHF diet.

Conclusions:

Both diets resulted in equal weight loss. The study showed similar effects on insulin resistance, low-fat and low-carbohydrate diets. The difference in the Augmentation Index can mean that a low – carbohydrate diet causes cardiovascular problems.

    Missing info to judge the study results:  1/ Reference to or name of study?, 2/ setting of study, 3/  participant compliance data in each group. 4/ study sponsor, 5/review and publication details.
    Further comments:  a/ I believe that equal weight loss was and can well be achieved with the significant reduction in calories in both groups as presented. I suspect however that the study was made in an institution , like a jail for instance , if all participants followed through since the high carb group would tend to go constantly hungry. The 500 cal reduction  would generate significant cravings in the high carb group that would generate fallouts in a free setting, outside institutional enforcement.  Also  20% carbs is too much carbs to be classified as a low carb diet that would accept max 10%, better 5%, carbs.   Finally a John Hopkins institute- well published finding – contradicts the results. Google  “..  John Hopkins low-carb higher fat arterial risks” to find the study.The results are also contradicted by preliminary Swedish results of  LCHF diet indicating a  reduction in arterial stiffness from LCHF. Average age reduction comparing arterial stiffness with average age related for the population was  5.6 year after 3.4 years on LCHF.   Translations not available yet.
