In the picture to the right you can see the lunch that I was unbelievably served at the 11th International Congress on Obesity in Stockholm 2010. This is a major international conference for obesity doctors and scientists. The food contains almost exclusively energy from sugar and starches, things that are broken down to simple sugars in the stomach.
Joseph, you should talk with your doctor or diabetes educator about this. In general, you can take metformin with most herbs, but your case might be different, and you might not need to. You might have to experiment. The same with insulin, although you have to be more careful there — in all cases you should work with your doctor or diabetes educator.
Recent global increase in diabetes, especially type II diabetes, is a product of the global obesity epidemic and attendant increase in Metabolic syndrome. In turn this has fueled an increase in surgical intervention in the form of Bariatric surgery. Diabetes reversal often follows sustained weight loss and indeed a 2014 Cochrane review of such surgeries found diabetes improvement in 5 randomized clinical trials (4). However, depending on the country and insurance plans, such weight loss surgery can be costly. They're also not risk-free with risks varying greatly depending on the person's overall health profile and age as well as skill and experience of the surgeon.
If you google “diabetes cure” you are directed to websites like WebMD and the Mayo Clinic where you find information on diet, exercise, medication, and insulin therapy, but nothing about the cure. This lack of information may have to do with the fact that Americans spend $322 billion a year to treat diabetes, $60 billion a year on weight-loss programs, and $124 billion a year on snack foods. This is about 3% of the US economy! Because so many peoples’ livelihoods are supported by diabetes and its main cause, obesity, the viral effect of people getting cured and telling others is greatly diminished.
