That Health Rules

Finally a study that looked at the practice of using low carbohydarte diet for our diabetics in helping control their blood glucoses was recently published in Nutrition and Metabolism journal.  Everytime I give a lecture on Nutritional therapy the question of my practice in lowering the total carbohydrate content of the calorie intake is the central issue.  This study is one proof that the concept of limiting the carbs can do wonders to ones blood sugar!

Objective

Dietary carbohydrate is the major determinant of postprandial glucose levels, and several clinical studies have shown that low-carbohydrate diets improve glycemic control. In this study, we tested the hypothesis that a diet lower in carbohydrate would lead to greater improvement in glycemic control over a 24-week period in patients with obesity and type 2 diabetes mellitus. Research design and methods: Eighty-four community volunteers with obesity and type 2 diabetes were randomized to either a low-carbohydrate, ketogenic diet (<20 g of carbohydrate daily; LCKD) or a low-glycemic, reduced-calorie diet (500 kcal/day deficit from weight maintenance diet; LGID). Both groups received group meetings, nutritional supplementation, and an exercise recommendation. The main outcome was glycemic control, measured by hemoglobin A1c.

Results

Forty-nine (58.3%) participants completed the study. Both interventions led to improvements in hemoglobin A1c, fasting glucose, fasting insulin, and weight loss. The LCKD group had greater improvements in hemoglobin A1c (-1.5% vs. -0.5%, p=0.03), body weight (-11.1 kg vs. -6.9 kg, p=0.008), and high density lipoprotein cholesterol (+5.6 mg/dL vs. 0 mg/dL, p<0.001) compared to the LGID group. Diabetes medications were reduced or eliminated in 95.2% of LCKD vs. 62% of LGID participants (p<0.01).

Conclusions

Dietary modification led to improvements in glycemic control and medication reduction/elimination in motivated volunteers with type 2 diabetes. The diet lower in carbohydrate led to greater improvements in glycemic control, and more frequent medication reduction/elimination than the low glycemic index diet. Lifestyle modification using low carbohydrate interventions is effective for improving and reversing type 2 diabetes.

What is amazing of the results is that by following a low carb diet, diabetes medications were reduced or eliminated in 95 percent and likewise resulted in a greater weight loss.  We also know that by losing weight, patient becomes more insulin sensitive and therefore contributes further to improvements in metabolic profile. These are the two effects that we like whether we employ diet or medication to any patient we assessed to have a disease of the lifestyle. 

Is this nutritional therapy easy to do? 

Definitely not BUT its the determination to succeed and be treated without medication that can drive our patients to follow the regimen.  Just like any regimen involving FOOD… our vigilance to do what is healthy is more important than following our DESIRE to love food and EAT more!
