Check it out, from Weight of Evidence comes an incredible story about an innovative town that did a "180" to change it's eating habits to that of mostly fat and protein sources such as meat, eggs, cream, cheese, and non-starchy vegetables. They had set out to prove our Western diet (rich in carbohydrates) is the cause of our decaying health.
 
And prove it they did:

As the CBC reported, "[h]e set up a year-long study of the diet in Alert Bay, where 60 people agreed to live on a more traditional aboriginal diet of meat, seafood and non-starch vegetables such as cauliflower.His theory is that sharply reducing the consumption of carbohydrates and sugar will cut deeply into the very high rates of obesity and diabetes in native communities.

People who took part in the study lost significant amounts of weight, Wortman said. They also showed improvements in their cholesterol levels and diabetes control."

In this study's subjects, it is reported that they:

• Lost 10.1% of body weight
• Shed 9.7% of their waist circumference
• Improved their waist-to-hip ratios significantly
• Triglycerides (TG) declined 19.9%
• HDL rose 17.4%
• TG/HDL ratio improved 30.2%
• TC/HDL ratio improved 11.5%
• Total Cholesterol (TC) and LDL had no significant change

More importantly, in the initial analysis, those with diabetes were found to have significant improvements in their HbA1c levels - seeing a decline from a mean 7.1% to a mean 6.1%. This is again a study that finds diet alone improves HbA1c significantly while also reducing or eliminating medication!
