There isn't "a" Mediterranean diet. Greeks eat differently from Italians, who eat differently from the French and Spanish. But they share many of the same principles. Working with the Harvard School of Public Health, Oldways, a nonprofit food think tank in Boston, developed a consumer-friendly Mediterranean diet pyramid that offers guidelines on how to fill your plate – and maybe wineglass – the Mediterranean way.
The Mediterranean diet is easy to find in the grocery store, contains nutrients that are known to enhance longevity and has other health benefits that are backed by peer-reviewed, scientific studies. Broccoli makes the list because it's one of nature's most nutrient-dense foods, with only 30 calories per cup. That means you get a ton of hunger-curbing fiber and polyphenols -- antioxidants that detoxify cell-damaging chemicals in your body -- with each serving.
The risks are more long term, such as risk of nutritional deficiency (vitamin c, a, k and b vitamins) and also increased risk of bowel and possibly breast cancer cancer due to limited fibre intake. Ketosis generally isn’t recommended and it’s not exactly a state that would the body would usually be in, but it can be done safely for set periods of time.’
My pick for the healthiest meal plan for diabetes? My favorite is the Mediterranean Diet. It’s high in fiber, low in saturated fats and includes no processed foods which is the challenge for all of us at this point in history. If we could all eat like they do in Italy and Greece! Think of Sicily and the coasts of Greece where their diet consists of fresh fish, fresh fruits and vegetables, nuts, beans, seeds, olives and olive oil, lean meats such as chicken and pork, some eggs and little red meat. The American Heart Association recommends it as well as the American Diabetes Association as being one healthy diet choice for people with diabetes.
Using the Bulletproof Diet, including Brain Octane Oil every day for long periods of time, and eating carbohydrates some of the time but not always, avoiding inflammatory foods, and using Bulletproof Intermittent Fasting, I was able to recently test with perfect insulin sensitivity — I scored a one on a scale of 1 to 120 (see my numbers below). I also had above average glucose tolerance. That’s metabolic flexibility by the numbers!
Grains and beans are some of the most carbohydrate-dense foods out there, so breads, rice, and beans will spike your blood sugar causing crashes and cravings later on. There’s more to the issue with grains and beans, though. They contain some proteins and compounds that humans just don’t handle well. Here’s a breakdown of some of the issues with grains and beans.
Diabetes is one of the most common chronic diseases in the world. In 2014, diabetes affected about 387 million people worldwide and resulted in $612 billion dollars of health-related costs.  Unfortunately, as a conventional western lifestyle of poor nutrition and exercise habits becomes more popular, diabetes is expected to affect about 592 million people worldwide.  In the United States alone, diabetes increased from 5.58 diagnosed cases in 1980 to 22.3 million diagnose cases in 2013. 
Implementing the diet can present difficulties for caregivers and the patient due to the time commitment involved in measuring and planning meals. Since any unplanned eating can potentially break the nutritional balance required, some people find the discipline needed to maintain the diet challenging and unpleasant. Some people terminate the diet or switch to a less demanding diet, like the modified Atkins diet (MAD) or the low-glycaemic index treatment (LGIT) diet, because they find the difficulties too great.
I started on a strict keto diet one year ago, and it has been the easiest diet I have ever been on. I was prediabetic before the diet, and now am not. My triglycerides are lower ( in normal range) and my good cholesterol is high. I am at lower than normal risk for heart disease because of my cholesterol ratios. I was not overweight to start with, am not now….and have not changed my weight at all. So the good effects are due solely to the diet change and not weight loss, which the author implies throughout the article that it is the weight loss that causes the good effects….not so. I am a veterinarian and believe in good medicine. This diet makes sense biochemically for those with diabetes or prediabetes.
At first glance the ketogenic (keto) diet may seem like a crazy idea for type 2 diabetics. After all, many patients are put on diets to help them lose weight. The keto diet is high in fat, but it is very low in carbs, and this combination can help change the way your body stores and uses energy. With this diet your body converts fat instead of sugar into energy, which can improve blood glucose levels while reducing the need for insulin.
A slew of articles in recent months have referred to the ketogenic diet as a “fad” or “trend.” It’s “dangerous,” claimed one article, and an anonymous post by the Harvard Public School of Public Health said the diet “comes with serious risks.”1 Yet strangely, these critics seldom cite scientists or doctors who work with the diet, and many—including the Harvard article—cite no medical literature to substantiate their allegations. Without substantiation, many simply rehash long-contradicted, outdated claims.
One study from 2005 followed 22 people with Type 1 Diabetes for 12 months. The difference here however is they consumed 70-90 grams of carbohydrates per day versus the restrictive less than 20 grams per day on the Ketogenic Diet. Remember my motto? Moderation is the key! The results were positive; less hypoglycemia, insulin requirements were reduced and their A1c dropped from 7.5% to 6.4%.
The fact is, the stress that you will bring on yourself from constantly restricting every single thing you put in your mouth is far more detrimental to your health. Remember, moderation is the key! You can count your carbohydrates and follow a sensible low carbohydrate diet to control your blood glucose and your weight. Exercise will always be the key component to add that contributes to added weight loss.
To follow the plan, one must decide their calorie level and then divide the suggested servings of each food group throughout the day. This requires meal planning ahead of time. The NHLBI guide provides many tips on how to incorporate DASH foods and to lower sodium intake; a one-day sample menu following a 2300 mg sodium restriction and a 1500 mg sodium restriction; and one week’s worth of recipes. The NHLBI also publishes an online database of “heart healthy” recipes.
Other down sides: There’s an initial period where your body is adjusting to its new carb-free existence, and many people experience symptoms like fatigue, brain fog and nausea for a few weeks. You also end up deficient in important micronutrients, like folate, calcium and potassium, which is why most ketogenic devotees recommend taking multivitamins. Personally, I recommend my clients follow a diet that in its ideal state provides all of the nutrients you need through real, whole foods.
It is important to understand that the statement that carbohydrates are “nonessential” is not only factually inaccurate, it results in adopting a low-carbohydrate diet or ketogenic diet that increases your risk for a wide variety of chronic health conditions that may ultimately shorten lifespan, decrease your quality of life, and accelerate your risk for chronic disease.
When carbohydrates are used by the body as an energy source, the blood sugar levels become unstable. As the energy source is not consistent it is difficult for your brain to stay focused for long periods of time. On the other hand, when you are in ketosis and the brain uses ketones as a fuel source, which has a consistent fuel source and you can focus for longer periods of time. Hence, you also tend to feel more active and alert.
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.
