In a 24-week long intervention study, researchers recruited 84 obese subjects with type 2 diabetes and randomly divided them into two groups. The first group of 42 received a low-glycemic diet with a 500 calorie/day deficit. The second group ate a very low carbohydrate ketogenic diet with less than 20 grams of carbohydrates per day without calorie restriction.
It seems strange that a diet that calls for more fat can raise “good” cholesterol and lower “bad” cholesterol, but ketogenic diets are linked to just that. It may be because the lower levels of insulin that result from these diets can stop your body from making more cholesterol. That means you’re less likely to have high blood pressure, hardened arteries, heart failure, and other heart conditions. 
But the DASH Diet isn’t a magic solution if you’re looking for quick weight loss. “I do think that if people follow this diet, there can be healthy weight loss,” says Srinath, “but weight loss is also tied to calorie restriction.” If you’re looking to drop, say, 20 pounds, you’ll have to consume fewer calories in addition to hitting the recommended serving amounts. Still, if you currently follow a pretty junky diet, you could easily wind up cutting the necessary calories with DASH, she explains.
In Asia, the normal diet includes rice and noodles as the main energy source, making their elimination difficult. Therefore, the MCT-oil form of the diet, which allows more carbohydrate, has proved useful. In India, religious beliefs commonly affect the diet: some patients are vegetarians, will not eat root vegetables or avoid beef. The Indian ketogenic diet is started without a fast due to cultural opposition towards fasting in children. The low-fat, high-carbohydrate nature of the normal Indian and Asian diet means that their ketogenic diets typically have a lower ketogenic ratio (1:1) than in America and Europe. However, they appear to be just as effective.[53]
The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.
A relatively new offering, the Nutritarian diet is based on maximizing the amount of healthy vitamins, minerals, and trace nutrients in your food, balancing your hormones, and avoiding toxins. The plan—created by Joel Fuhrman, M.D., author of The End of Dieting—is nutrient-dense, plant-rich, and includes anti-cancer superfoods to help you not just lose weight but live a long, disease-free life. (P.S. Follow these guidelines to make sure you're absorbing all the nutrients from your food.)
What the diet advocate says: 'The classic keto diet was very strict and nowadays what’s become more popular even to use from a clinical scenario is called the Modified Keto diet which is more liberal in protein. And that’s generally what people are following for weight loss and energy. That would be roughly 65-70% fat, 20-30% protein with a very small carb amount 5-10%,’ says Dr Dominic D’agostino, professor of neuropharmacology at the University of South Florida.

After seeing thousands of patients now for years and from personal experience, I still believe it comes down to staying away from processed foods and cooking at home whenever possible. Eating a variety of fresh fruits, vegetables, proteins, and fiber. Also, cutting out any sugary liquid calories; staying away from sodas, juices and the infamous sweet tea! Keeping stress levels under control and incorporating exercise into your routine will also be key to breaking through challenging times when you are having trouble with continued weight loss.
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.[41]
Over 8–10 mmol/l: It’s normally impossible to get to this level just by eating a keto diet. It means that something is wrong. The most common cause by far is type 1 diabetes, with severe lack of insulin. Symptoms include feeling very sick with nausea, vomiting, abdominal pain and confusion. The possible end result, ketoacidosis, may be fatal and requires immediate medical care. Learn more
