Results of meta-analysis of 12 large studies conducted between 1966 and 2008, covering more than 1.5 million subjects, were published in the British Journal of Nutrition in 2009. The authors concluded that the Mediterranean diet is associated with significant health benefits, including lower mortality overall, and reduced risk of chronic diseases like heart disease, cancer, Alzheimer’s and Parkinson’s.
Not to be outdone, oolong tea—a Chinese beverage—can help those who drink it shed up to a pound per week. According to a study in the Chinese Journal of Integrative Medicine, participants who regularly sipped oolong tea lost six pounds over the course of six weeks. What’s more? The tea’s antioxidants are thought to remove harmful free radicals and improve bone health.
Throughout this article, we looked at the data and the principles behind how low-carb dieting affect patients with diabetes, but we never addressed what you can do about it directly. If you’d like to learn about practical strategies that may help you reverse insulin resistance and improve your blood sugar and HbA1C levels, I recommend reading these articles:
However, the meta-analysis was riddled with confounding variables — one of which being their lackadaisical definition of a low-carb diet. The researchers identified a low-carb diet as a diet where less than 45% of its calories come from carbs. With such a lax criterion for low-carb, it is difficult to tell if a true low-carb diet (i.e., fewer than 26% of calories coming from carbs) is genuinely the best dietary option for type 2 diabetics.
Kefir is a yogurt-like substance, but it actually contains less sugar and more protein than conventional yogurt while remaining packed with gut-friendly probiotics that can help you lose weight by aiding digestion. In one study, kefir displayed weight loss properties similar to those of milk and other dairy-rich products. Other probiotic-rich foods include kombucha, bone broth, and fermented items such as sauerkraut and kimchi.
Grains and beans are high in lectins, and it’s no surprise that the top allergen foods also have a high lectin content. The lectins in nightshade vegetables can be troublesome for some people, while others handle them just fine. Cooking and peeling removes some of the lectin content in vegetables (but not grains, they’re pretty heat stable), but some super-sensitive people have to avoid them completely.
It usually takes three to four days for your body to go into ketosis because you have to use up your body's stores of glucose, i.e., sugar first, Keatley says. Any major diet change can give you some, uh, issues, and Keatley says he often sees patients who complain of IBS-like symptoms and feeling wiped out at the beginning of the diet. (The tiredness happens because you have less access to carbs, which give you quick energy, he explains.)
Lectins are another way plants defend themselves. Food naturally wears and tears your gut lining as it passes through. The normal repair process is part of the digestion program. Lectins interfere with the repair by binding to the lining of your gut and blocking healing. This leaves microscopic holes in the gut, which allows undigested food particles to pass through, and then you find yourself constantly afflicted with low-level inflammation.
The DASH diet plan focus on increasing vegetables, fruits, whole grains, and legumes; choosing lean meats, low-fat dairy, nuts and healthy fats; and limiting added sugars, trans fats, added salt, and processed foods. Serving sizes from each food group are based on individual calorie needs (see below for a 1600-calorie plan), and you’ll likely find that the plan looks pretty close to the MyPlate plan, as well as another consistently rated “top diet,” the Mediterranean Diet. Here’s a breakdown of the recommended nutrients in a typical day and week on the DASH diet:
As for individuals with type 2 diabetes, Dr. Galati says, "a very low carbohydrate diet could be tolerated, albeit with extreme caution. Transitioning to a ketogenic diet will require several lifestyle changes as well as careful monitoring of both your food intake and glucose levels and adjustments to your medications. Also, you should increase your water consumption."
DASH stands for Dietary Approaches to Stop Hypertension. It’s a lifelong approach to eating that’s designed to prevent and treat high blood pressure, also called hypertension. It also falls in line with dietary recommendations to prevent osteoporosis, cancer, heart disease, stroke, and diabetes. DASH encourages a variety of nutrient-rich foods while reducing the amount of sodium eaten. This eating plan includes plenty of fruits, vegetables, whole grains, low-fat dairy products, fish, poultry, legumes, nuts, and seeds. Red meat and sweets are eaten in small amounts.
The first meta-analysis worth noting collected the data from 10 randomized trials comprising 1376 participants in total.  After analyzing the research, a key relationship emerged between dietary carbs and blood sugar levels. In short, the researchers described their finding thus: “the greater the carbohydrate restriction, the greater glucose lowering…” 
A small Feb. 20, 2017, study looked at the impact of a six-week ketogenic diet on physical fitness and body composition in 42 healthy adults. The study, published in the journal Nutrition & Metabolism, found a mildly negative impact on physical performance in terms of endurance capacity, peak power and faster exhaustion. Overall, researchers concluded, “Our findings lead us to assume that a [ketogenic diet] does not impact physical fitness in a clinically relevant manner that would impair activities of daily living and aerobic training.” The “significant” weight loss of about 4.4 pounds, on average, did not affect muscle mass or function.
The Mediterranean Diet was identified in the 1960s as research continued to show populations from Mediterranean regions, particularly Southern Italy, the isle of Crete, and Greece, were considerably healthier, with less incidence of disease and longer lifespans than seen in other regions. Studies indicated that the way these populations ate seemed to be the common denominator and through research, the Mediterranean diet was formally born.

The benefits above are the most common ones. But there are others that are potentially even more surprising and – at least for some people – life changing. Did you know that a keto diet can help treat high blood pressure, may result in less acne, may help control migraine, might help with certain mental health issues and could have a few other potential benefits?
