Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.
Type I diabetes is usually inherited and type I diabetics usually have to inject insulin to maintain proper levels of blood glucose. The other 90% to 95% of people with diabetes are type II diabetics.  In this version, the body doesn’t produce enough insulin for proper function or cells in the body do not react to insulin and take in sugar from the blood.

In regard to serum measurements, the mean fasting glucose decreased by 17% from 9.08 ± 4.09 mmol/L at baseline to 7.57 ± 2.63 mmol/L at week 16 (p = 0.04) (Table (Table4).4). Serum sodium and chloride levels increased significantly, but only by 1% and 3%, respectively. Uric acid level decreased by 10% (p = 0.01). Serum triglyceride decreased 42% from 2.69 ± 2.87 mmol/L to 1.57 ± 1.38 mmol/L (p = 0.001). Increases occurred in both high-density lipoprotein (HDL) cholesterol (8%) and low-density lipoprotein (LDL) cholesterol (10%) but these changes were of borderline statistical significance (p = 0.08 and p = 0.1, respectively). The following blood tests did not change significantly: total cholesterol, potassium, bicarbonate, urea nitrogen, creatinine, calcium, thyroid-stimulating hormone, and hemoglobin.
This diet plan will be especially important for people with metabolic syndrome, prediabetes, or diabetes. Post menopausal women will find that this plans helps them lose that extra midlife weight that is so troublesome. It will reduce your body's demand for insulin, and reduce the tendency to deposit fat in your midsection. Yes, that's right - this plan will reduce your waist size, which is an important indicator of health risks.
The ketogenic diet achieved national media exposure in the US in October 1994, when NBC's Dateline television programme reported the case of Charlie Abrahams, son of Hollywood producer Jim Abrahams. The two-year-old suffered from epilepsy that had remained uncontrolled by mainstream and alternative therapies. Abrahams discovered a reference to the ketogenic diet in an epilepsy guide for parents and brought Charlie to John M. Freeman at Johns Hopkins Hospital, which had continued to offer the therapy. Under the diet, Charlie's epilepsy was rapidly controlled and his developmental progress resumed. This inspired Abrahams to create the Charlie Foundation to promote the diet and fund research. A multicentre prospective study began in 1994, the results were presented to the American Epilepsy Society in 1996 and were published in 1998. There followed an explosion of scientific interest in the diet. In 1997, Abrahams produced a TV movie, ...First Do No Harm, starring Meryl Streep, in which a young boy's intractable epilepsy is successfully treated by the ketogenic diet.

For the ketogenic eating plan, participants were instructed to reduce non-fiber-containing carbohydrates to between 20 and 50 grams a day, with no calorie restriction. The group following the plate method were told to eat their meals on a nine-inch plate, filling half of it with non-starchy vegetables (eg, greens, peppers, broccoli, carrots), ¼ of the plate with whole grains (eg, brown rice, sweet potatoes, whole wheat bread) and adding lean protein (eg, skinless chicken, turkey, fish, and seafood) to the last quarter of the plate.1
Wondering what fits into a keto diet — and what doesn’t? “It’s so important to know what foods you’ll be eating before you start, and how to incorporate more fats into your diet,” says Kristen Mancinelli, RD, author of The Ketogenic Diet: A Scientifically Proven Approach to Fast, Healthy Weight Loss, who is based in New York City. We asked her for some guidelines.
The keto diet is NOT what you seem to picture. I laughed at your description as I was eating lamb chops, cauliflower rice, broccoli, followed by cheesecake. How deprived I was! You should relook at what the diet really is. By the way, my cardiologist highly recommends keto. Most people see a drastic decrease in their triglyceride/HDL ratio. Looking at total cholesterol or LDL alone is 20 years out of date! Even the AHA has caught up, and now says that it’s NOT how heart health should be judged.
Burns fat: You can drop a lot of weight — and quickly — on the keto diet. Ketones suppress ghrelin — your hunger hormone — and increase cholecystokinin (CCK), which makes you feel full. Reduced appetite means it’s easier to go for longer periods without eating, which encourages your body to dip into its fat stores for energy. Learn more here about the keto diet and weight loss.
Probably, and there are a few reasons why the keto diet usually equals weight-loss gold, says Keatley. For starters, people usually reduce their daily caloric intake to about 1,500 calories a day because healthy fats and lean proteins make you feel fuller sooner—and for a longer period of time. And then there’s the fact that it takes more energy to process and burn fat and protein than carbs, so you're burning slightly more calories than you did before. Over time, this can lead to weight loss.
When compared to the calorie-restrict diet, the subjects who underwent the ketogenic diet experienced a reduction three times greater in hemoglobin A1C (1.5% vs. 0.5%).  In addition to observing greater improvements in diabetes-related markers, researchers observed a greater reduction in medication usage in subjects that underwent the ketogenic diet treatment. Thus, due to their overall findings, the researchers stated that “Lifestyle modification using low carbohydrate interventions is effective for improving and reversing type 2 diabetes.” 
In addition to its 4 grams of belly-filling fiber, a cup of hearty oatmeal delivers as much protein as an egg. In other words, the popular breakfast food is an excellent weight loss tool. In fact, according to a study in the Annals of Nutrition and Metabolism, scientists found that having oatmeal for breakfast resulted in greater fullness, lower hunger ratings, and fewer calories eaten at the next meal compared with a serving of ready-to-eat sugared corn flakes, even though the calorie counts of the two breakfasts were identical. For an added fiber boost, sprinkle some berries and chia seeds on top of your oatmeal, but be sure to stay away from fattening syrup and sugar.

In the first week, many people report headaches, mental fogginess, dizziness, and aggravation. Most of the time, this is the result of your electrolytes being flushed out, as ketosis has a diuretic effect. Make sure you drink plenty of water and keep your sodium intake up.6One of the fathers of keto, Dr. Phinney, shows that electrolyte levels (especially sodium) can become unbalanced with low carb intake.
Before starting, ask yourself what is really realistic for you, Mattinson suggests. Then get your doctor’s okay. You may also work with a local registered dietitian nutritionist to limit potential nutrient deficiencies and talk about vitamin supplementation, as you won’t be eating whole grains, dairy, or fruit, and will eliminate many veggies. “A diet that eliminates entire food groups is a red flag to me. This isn’t something to take lightly or dive into headfirst with no medical supervision,” she says.
