Atkins Diet Misconceptions: Low Carb and Diabetes (Part 2)
Wednesday, September 9th, 2009
This video is the second half of the Atkins Diet Misconception: Diabetes series. If you have not seen Part 1, please watch it here:
The last video dealt with case damning the existing treatment or recommendations to follow a high carb diet managed with ever increasing doses of insulin. This video deals with the evidence for rather managing it with a low carb lifestyle. There are two great studies for advocating this method.

Conducted Multi-center trial in which 63 obese men and women were randomly assigned to either diet, 21 Low Carb, 21 Control, 21 High Carb for a one year study.
This discussion focuses on type 2 diabetes but many of the principles will apply to metabolic syndrome and possibly to type 1 as well[6,7].
1. Carbohydrate restriction improves glycemic control, the primary target of nutritional therapy and reduces insulin fluctuations.
2. Carbohydrate-restricted diets are at least as effective for weight loss as low-fat diets.
3. Substitution of fat for carbohydrate is generally beneficial for markers for and incidence of CVD.
4. Carbohydrate restriction improves the features of metabolic syndrome.
An important idea guiding current medical thinking is that clustering of seemingly disparate physiologic states, obesity, atherogenic dyslipidemia, hyperglycemia and hypertension, termed metabolic syndrome (MetS) suggests a common underlying cause. A recent review showed that carbohydrate restriction improves all of these markers[24].
5. Beneficial effects of carbohydrate restriction do not require weight loss. It’s not simply a weight loss argument or due to people losing weight do they achieve the benefits.
2.) Low-carbohydrate diet in type 2 diabetes: stable improvement of bodyweight and glycemic control during 44 months follow-up

Conclusion:
There is now little evidence for the claim that a fat-reduced diet for weight reduction has any particular value beyond caloric counting [10]. Current dietary recommendations seem to be a major part of their problem rather than being part of the solution. Carbohydrate restriction, however, reverses or neutralises all aspects of the metabolic syndrome [20,21].
