Fasting plasma glucose concentration depends entirely on the fasting rate of hepatic glucose production and, hence, on its sensitivity to suppression by insulin. Hepatic insulin sensitivity cannot be inferred from observed postprandial change in hepatic glycogen concentration because glucose transport into the hepatocyte is not rate limiting, unlike in muscle, and hyperglycemia itself drives the process of glycogen synthesis irrespective of insulin action. Indeed, postprandial glycogen storage in liver has been shown to be moderately impaired in type 2 diabetes (50) compared with the marked impairment in skeletal muscle (51).
“In the realm of fatty liver disease, which is highly associated with either prediabetes or fully diagnosed type 2 diabetes, we do know that decreased fat and decreased weight are associated with far better glucose control,” says Galati, who is the author of Eating Yourself Sick: How to Stop Obesity, Fatty Liver, and Diabetes From Killing You and Your Family. “This research reinforces the idea that patients with type 2 diabetes who are obese — which is the vast majority — can improve their blood sugar control as well as their long-term outlook with weight loss.”
They would often say to me, “Doctor. You’ve always said that weight loss is the key to reversing diabetes. Yet you prescribed me a drug that made me gain 25 pounds. How is that good?” I never had a good answer, because none existed. The truth was that insulin was not good for type 2 diabetes — it was only good for reducing blood glucose. The key was weight loss, whereupon the diabetes often goes away or at least gets significantly better. So, logically, insulin does not help reverse the disease, but actually worsens it.
9. Exercise! Moderate to vigorous exercise that includes both cardio and strength building components are great ways to keep the body fit. Exercise can also contribute to a more positive outlook on life, which can boost the immune system, provide capacity for healthier coping strategies, and decrease stress. Yoga, hiking, and jogging are all good options. To boost your metabolism, make sure your work-outs incorporate strength training. It is also far more effective to incorporate high intensity interval workouts to your regime, such as sprinting and HIIT workouts.
Yet Gabbay says preliminary human studies with positive results, like this week’s in BMJ Case Reports, suggest the diet is worthy of further study in a larger population over a longer period of time. For now, he cautions people with diabetes, especially those on insulin and sulfonylureas to lower their blood sugar, against trying intermittent fasting before speaking with their healthcare provider.
