Study Reveals How A Very Low Calorie Diet Can Reverse Type 2 Diabetes

November 11, 2017 – By Ziba Kashef – In a brand new research, a Yale-led analysis crew uncovers how a really low calorie eating regimen can quickly reverse sort 2 diabetes in animal fashions. If confirmed in folks, the perception gives potential new drug targets for treating this widespread DiabetesType2power illness, mentioned the researchers.

The research is printed in Cell Metabolism.

One in three Americans will develop sort 2 diabetes by 2050, in response to latest projections by the Center for Disease Control and Prevention. Reports point out that the illness goes into remission in lots of sufferers who bear bariatric weight-loss surgical procedure, which considerably restricts caloric consumption previous to clinically vital weight reduction. The Yale-led crew’s research centered on understanding the mechanisms by which caloric restriction quickly reverses sort 2 diabetes. 

The analysis crew investigated the results of a really low calorie eating regimen (VLCD), consisting of one-quarter the traditional consumption, on a rodent mannequin of sort 2 diabetes. Using a novel secure (naturally occurring) isotope strategy, which they developed, the researchers tracked and calculated numerous metabolic processes that contribute to the elevated glucose manufacturing by the liver. The methodology, referred to as PINTA, allowed the investigators to carry out a complete set of analyses of key metabolic fluxes inside the liver which may contribute to insulin resistance and elevated charges of glucose manufacturing by the liver — two key processes that trigger elevated blood-sugar concentrations in diabetes.

Using this strategy the researchers pinpointed three main mechanisms answerable for the VLCD’s dramatic impact of quickly reducing blood glucose concentrations within the diabetic animals. In the liver, the VLCD lowers glucose manufacturing by: 1) lowering the conversion of lactate and amino acids into glucose; 2) lowering the speed of liver glycogen conversion to glucose; and three) lowering fats content material, which in flip improves the liver’s response to insulin. These constructive results of the VLCD had been noticed in simply three days.

Using this strategy to comprehensively interrogate liver carbohydrate and fats metabolism, we confirmed that it’s a mixture of three mechanisms that’s answerable for the fast reversal of hyperglycemia following a really low calorie eating regimen,” mentioned senior creator Gerald I. Shulman, M.D., the George R. Cowgill Professor of Medicine and Cellular and Molecular Physiology and an investigator on the Howard Hughes Medical Institute.

The subsequent step for the researchers can be to substantiate whether or not the findings may be replicated in sort 2 diabetic sufferers present process both bariatric surgical procedure or consuming very low calorie diets. His crew has already begun making use of the PINTA methodology in people.  

These outcomes, if confirmed in people, will present us with novel drug targets to extra successfully deal with sufferers with sort 2 diabetes,” Shulman mentioned.
