The earliest predictor of the development of type 2 diabetes is low insulin sensitivity in skeletal muscle, but it is important to recognize that this is not a distinct abnormality but rather part of the wide range expressed in the population. Those people in whom diabetes will develop simply have insulin sensitivity, mainly in the lowest population quartile (29). In prediabetic individuals, raised plasma insulin levels compensate and allow normal plasma glucose control. However, because the process of de novo lipogenesis is stimulated by higher insulin levels (38), the scene is set for hepatic fat accumulation. Excess fat deposition in the liver is present before the onset of classical type 2 diabetes (43,74–76), and in established type 2 diabetes, liver fat is supranormal (20). When ultrasound rather than magnetic resonance imaging is used, only more-severe degrees of steatosis are detected, and the prevalence of fatty liver is underestimated, with estimates of 70% of people with type 2 diabetes as having a fatty liver (76). Nonetheless, the prognostic power of merely the presence of a fatty liver is impressive of predicting the onset of type 2 diabetes. A large study of individuals with normal glucose tolerance at baseline showed a very low 8-year incidence of type 2 diabetes if fatty liver had been excluded at baseline, whereas if present, the hazard ratio for diabetes was 5.5 (range 3.6–8.5) (74). In support of this finding, a temporal progression from weight gain to raised liver enzyme levels and onward to hypertriglyceridemia and then glucose intolerance has been demonstrated (77).
A 2005 study on the anti-diabetic effect of garlic in normal and lab-induced diabetic rats, published in the journal Phytomedicine, found that oral administration significantly decreased serum glucose, total cholesterol, triglycerides, urea, uric acid, creatinine, AST and ALT levels. While it increased serum insulin in diabetic rats, this was not so in the case of normal rats. It concluded that garlic must be considered as an excellent candidate for future human studies on diabetes mellitus. What’s better, garlic also helps reduce high cholesterol levels, a complication that diabetics often face. This makes it an excellent spice to use for in all recipes!
A couple of studies have found that cinnamon improves blood glucose control in people with type 2 diabetes. In the first study, 60 people with type 2 diabetes were divided into six groups. Three groups took 1, 3 or 6 g of cinnamon a day and the remaining three groups consumed 1, 3 or 6 g of placebo capsules. After 40 days, all three doses of cinnamon significantly reduced fasting blood glucose, triglycerides, LDL cholesterol, and total cholesterol.
You should have no more than three of these “feeding times” per day. The reason limiting the number and duration of your meal times is so important has to do with staying out of the vicious cycle of increasing insulin resistance. To get smart on insulin resistance — the cause of both type 2 diabetes and obesity — read Dr. Jason Fung’s book, The Obesity Code: Unlocking the Secrets of Weight Loss, or watch his free lecture on YouTube.
