Minerals/Electrolytes: Adopting a ketogenic diet will change the way your body uses (and loses) certain minerals. Not replacing these minerals can lead to symptoms of the “keto flu” such as lightheadedness, headaches, constipation, muscle cramps and fatigue. Refer to this article for tips on how to replace common minerals such as sodium, potassium, magnesium and calcium.

The inclusion criteria were ages 18 to 65 years, body mass index (BMI) ≥30 kg/m2, stable body weight in the previous 3 months, a desire to lose weight, and a history of failed dietary efforts. The main exclusion criteria were diabetes mellitus, obesity induced by other endocrine disorders or by drugs, and participation in any active weight loss program in the previous 3 months. In addition, those patients with previous bariatric surgery, known or suspected abuse of narcotics or alcohol, severe depression or any other psychiatric disease, severe hepatic insufficiency, any type of renal insufficiency or gout episodes, nephrolithiasis, neoplasia, previous events of cardiovascular or cerebrovascular disease, uncontrolled hypertension, orthostatic hypotension, and hydroelectrolytic or electrocardiographic alterations were excluded. Females who were pregnant, breastfeeding, or intending to become pregnant, and those with child-bearing potential who were not using adequate contraceptive methods, were also excluded. Apart from obesity and metabolic syndrome, participants were generally healthy individuals.
Instead of thinking about the total carbs you’re eating, assess what those carbs provide to you. Do the majority of your carbs come from fruit and vegetables, with a payload of fiber and disease-fighting antioxidants? Fantastic. Or are you consuming them in the form of added sugars (cookies, candy, soda) or refined flour? If you are, you know what to do.
If you’re one of the lucky people that have a dehydrator, you can take serious advantage of it by dehydrating thin slices of vegetables overnight (normally 12 hours) to get crisp, perfect vegetables that you can eat as snacks. Do this with zucchini, radish, or jicama. If you’re not lucky enough to have a dehydrator (like me), then you can easily make cheese chips in the oven and flavor them with your own spices!
Twenty calories a day times the 365 days in a year comes to a little more than seven thousand calories stored as fat every year—two pounds of excess fat. If it were true that our adiposity is determined by calories-in/calories-out, then this is one implication: you only need to overeat, on average, by twenty calories a day to gain fifty extra pounds of fat in twenty years. You need only to rein yourself in by this amount—undereat by twenty calories a day—to undo it. Twenty calories is less than a single bite of a McDonald’s hamburger or a croissant. It’s less than two ounces of Coke or Pepsi or the typical beer. Less than three potato chips. Maybe three small bites of an apple. In short, not very much at all. Twenty calories is less than 1 percent of the daily caloric intake that the U.S. National Academy of Sciences has recommended for a middle-aged woman whose idea of regular physical activity is cooking and sewing; it’s less than half a percent of the daily quota of calories recommended for an equally sedentary middle-aged man. That it’s such an insignificant amount is what makes it so telling about the calories-in/calories-out idea.
My advice is to keep your food plan in balance—eat mostly vegetables (about 1-2 pounds per day), eat the minimum protein to preserve lean body mass, avoid processed foods and those that inflame you, and track your body composition over time. Extreme works for some people, but not for me, and not for all women. I prefer getting into ketosis via intermittent fasting, on a 16/8 protocol.
“Each person’s journey is different, and therefore each person deserves a highly-specialized and individualized treatment plan to help them reach their optimal health. I recommend low-carb and ketogenic lifestyles to my patients and find ways to make them reasonable and sustainable for each person. Diet Doctor is a wonderful resource for my patients and provides wonderful recipes and invaluable information.”
We have solid evidence showing that a ketogenic diet reduces seizures in children, sometimes as effectively as medication. Because of these neuroprotective effects, questions have been raised about the possible benefits for other brain disorders such as Parkinson’s, Alzheimer’s, multiple sclerosis, sleep disorders, autism, and even brain cancer. However, there are no human studies to support recommending ketosis to treat these conditions.
You can receive the FULL benefit of the 3-Week Ketogenic Diet without adding any exercise during the 3-weeks you'll be following the plan. If you choose to incorporate at least an hour of metabolic exercise during the week using my personal-trainer guided exercise videos, you'll see up to THREE times the results. Exercise contributes to hormonal balance, blood sugar stability, and lean muscle growth.
A lot of veggies are carb-heavy—they can’t fit into an ultra-low-carb diet. These include potatoes of course, but also yams, corn, peas, and carrots. The best options for keto dieters include asparagus, bell peppers, Brussels sprouts, leafy greens, and zucchini. “What’s tough for many people to grasp when starting out on a ketogenic diet is that you can’t really eat a lot of [certain] vegetables,” Mancinelli says. “When you’re keeping carbs super low, you have to limit vegetables—which goes counter to everything you know about how to eat healthy and lose weight.”
Advocates for the diet recommend that it be seriously considered after two medications have failed, as the chance of other drugs succeeding is only 10%.[9][31][32] The diet can be considered earlier for some epilepsy and genetic syndromes where it has shown particular usefulness. These include Dravet syndrome, infantile spasms, myoclonic-astatic epilepsy, and tuberous sclerosis complex.[9][33]

Previous studies have shown that ketogenic diets preferably reduce the total FM in obese patients (10–13). However, the precise distribution of these losses has not been determined. In this study we confirmed that the diet reduces total FM and specifically visceral adipose tissue, which has a greater impact in predicting cardiometabolic complications associated with obesity than does the total volume of body adiposity (2, 31).
Rami co-founded Tasteaholics with Vicky at the start of 2015 to master the art of creating extremely delicious food while researching the truth behind nutrition, dieting and overall health. You can usually find him marketing, coding or coming up with the next crazy idea because he can’t sit still for too long. His favorite book is The 4-Hour Workweek and artist is Infected Mushroom.
In many developing countries, the ketogenic diet is expensive because dairy fats and meat are more expensive than grain, fruit and vegetables. The modified Atkins diet has been proposed as a lower-cost alternative for those countries; the slightly more expensive food bill can be offset by a reduction in pharmaceutical costs if the diet is successful. The modified Atkins diet is less complex to explain and prepare and requires less support from a dietitian.[55]
I was a Corpsman (not a corpse-man as some recent somewhat fanatical president would say), and I can tell you many stories of Marines and Sailors who maintained restrictive diets (aka picky eaters). Most obvious was lack of sustaining energy (hypoglycemia) at mile 15 (with 80lbs of gear including a 6.5lb rifle and 200 rnds of ammo, etc.) and depletion of essential vitamins, electrolyte imbalance. They were always the first to collapse and have to hear me scold “see I told you so.” An IV of D5W usually does the trick (D is for dextrose, OMG!)
