Because some cancer cells are inefficient in processing ketone bodies for energy, the ketogenic diet has also been suggested as a treatment for cancer. A 2018 review looked at the evidence from preclinical and clinical studies of ketogenic diets in cancer therapy. The clinical studies in humans are typically very small, with some providing weak evidence for anti-tumour effect, particularly for glioblastoma, but in other cancers and studies, no anti-tumour effect was seen. Taken together, results from preclinical studies, albeit sometimes contradictory, tend to support an anti-tumor effect rather than a pro-tumor effect of the KD for most solid cancers.
Fits in with the principles of eating and activity that I would recommend to clients: lots of produce-based meals and calcium-containing foods three times daily and exercise. Recipes look tasty. I would not necessarily recommend the lead-in period, but I like the meal plans main phase for losing weight as well the maintenance phase. I would recommend to friends and family as well
That doesn’t mean keto causes diabetes; it’s amazing for most diabetics. However, if your cells are great at processing fat, but suck at processing glucose or carbohydrates, you won’t be able to run at full power, and parts of your body that prefer glucose over fat — like the glial cells in your brain that handle immune function and synaptic pruning — don’t work as well over time.
Voted the "Best Diet Overall" for the past eight years in a row by U.S. News & World Report, the DASH diet can help you meet and maintain your health goals. The original intention of the DASH Diet (Dietary Approaches to Stop Hypertension) was to help lower high blood pressure (or hypertension), which research shows it does well. But even if you don't have high blood pressure, you might benefit from trying the DASH Diet, as research also shows it promotes weight loss and combats diabetes, all while being easy to follow and nutritious.
Body Fat Reduction. According to the current research literature, both visceral and subcutaneous fat play a role in the development of type 2 diabetes.  To keep our fat cells from fighting against us, we must adopt a healthier lifestyle that prevents us from being in a calorie surplus and gaining weight. The keto diet is one lifestyle change that has been proven time and time again to help us lose fat and improve metabolic health. 
Sleep enough – for most people at least seven hours per night on average – and keep stress under control. Sleep deprivation and stress hormones raise blood sugar levels, slowing ketosis and weight loss a bit. Plus they might make it harder to stick to a keto diet, and resist temptations. So while handling sleep and stress will not get you into ketosis on it’s own, it’s still worth thinking about.
