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. 
Kamut is an ancient grain native to the Middle East that is an excellent source of heart-healthy omega-3 fatty acids, protein, and fiber, while simultaneously being low in calories. In fact, a half-cup serving of the stuff has 30 percent more protein than regular wheat and just 140 calories. What’s more? A study published in the European Journal of Clinical Nutrition found that eating Kamut reduces cholesterol, blood sugar, and cytokines (which cause inflammation throughout the body). Kamut’s ability to stabilize blood sugar and reduce inflammation make it a great weight loss staple, especially if it is used in place of nutritionally lacking refined grains.
And what benefit you will have with “moderate” diets that let you eat bread and others carbohydrates but high insulin ? remember that it is critical to not only look after glucose levels on blood, it is very very important to reduce your intake of insulin to avoid a lot of diseases including metabolic syndrome for high insulin and insulin resistance.
I bought this book over three years ago and read/followed it fairly religiously . I lost 60 pounds and have not put it back on. Whenever I see the numbers on the scale creep up a bit, I "scale" back. I experienced so much more energy...even after just one week. AND I lost 8 pounds that first week! I'm sure a lot of that was fluid, but what the heck...I'll tank an 8 lb. loss. This has been a God-send and was so easy that I kicked myself for not doing it sooner. BTW, I'm not a kid...I was 56 year-old, still-experiencing-menopausal-symptoms-woman when I started. As I tell everyone, it's not a diet, it's a lifestyle!
For those who want to follow a ketogenic-type diet, Dr. Reynolds says it is important to first talk to your doctor and to discuss your goals so you can be sure that this approach is suitable for you given your medical and health history. Ongoing monitoring is needed if you do decide to adopt this very carb approach to eating. Seeing your doctor regularly is important to make sure that your blood pressure, lipids, blood sugar, mood, and medications are within normal ranges as you lose weight. Adjustments are likely going to be necessary from time to time.
