“I am a family physician and co-author of the book The Diabetes Diet. I have been advocating a low-carb diet for patients for the last 16 years — for weight loss weight, cardiac risk reduction, and better blood sugar control in type 1 and 2 diabetes. The diet enables patients with type 1 diabetes to reduce their insulin needs, while patients with type 2 diabetes on insulin may be able to eliminate the drug completely. I leave the choice as to whether the diet needs to be ketogenic or not up to patients, depending on their motivation and goals.”
It’s estimated that over 50% of people are deficient in Vitamin D worldwide[*]. Although Vitamin D doesn’t play a major role in whether or not you are in ketosis, it is responsible for regulating immunity, inflammation, hormones and helping with electrolyte absorption[*][*] — all factors important for weight loss and overall health. Additionally, studies support the direct benefits of vitamin D for weight loss[*][*][*]. You can check your Vitamin D levels with a simple blood test and then supplement accordingly. When supplementing, choose Vitamin D3 as it is the form that’s best absorbed by your body[*][*].
You’re ok with not so fast results and can remain disciplined.Every weight loss management plan needs an amount of sacrifice as well as a compromise from the dieter. But the ketosis approach may be one of the most challenging because it will change the most sacred of all eating routines among Western cultures: enjoying a full-dish meal. It's certainly no picnic, but the procedure can be done simpler having the right products and program, and the results can be spectacular.

The popular belief that high-fat diets cause obesity and several other diseases such as coronary heart disease, diabetes, and cancer has not been observed in recent epidemiological studies. Studies carried out in animals that were fed high-fat diets did not show a specific causal relationship between dietary fat and obesity. On the contrary, very-low-carbohydrate and high-fat diets such as the ketogenic diet have shown to beneficial to weight loss.
Adding heavy cream or half-and-half to your coffee is one way to get an additional source of fat into your day, says Keatley. Just realize that it is a source of saturated fat — and, given the small serving size, it’s easy to go overboard. According to the USDA, 1 tbsp has 51 calories, 5 g of fat (3.5 g saturated fat), and is just shy of ½ g of carbohydrate.
“I follow and recommend a low-carb or keto lifestyle, with and without intermittent fasting, to all of my patients whether or not they have lifestyle-related chronic conditions. I do this because of the health benefits to anyone who follows them, but also because of the science behind them and the impressive clinical results I have seen in my patients. I have recommended the Diet Doctor website for the past 5-6 years as a first-stop to find completely trustworthy information, delicious recipes, great visuals and excellent videos.”

One area where food tracking can be especially helpful, though, is ensuring that you're hitting the right ratios of macronutrients—protein, carbs, and fat. "The most researched version of the ketogenic diet derives 70 percent of calories from healthy fats, 20 percent from protein, and only 10 percent from carbs," explains Charles Passler, D.C., nutritionist, and founder of Pure Change. "In the ideal world, each keto meal and snack should have that same (70/20/10) ratio of macronutrients, but studies have shown that you'll still achieve great results even if each meal varies slightly from that ratio, just as long as you don't exceed 50 grams per day of carbs, or eat those carbs in one sitting," says Passler. In order to achieve these ratios without a preset meal plan from a dietitian or doctor, some food tracking is probably going to be necessary. But once you get the hang of things, you may not need it anymore.

Try and aim to keep your protein the same at one gram per pound of body weight and then take in 10-12 grams of carbohydrates for every kilogram of body weight. Start taking these carbohydrates (usually the first bit in liquid form) right after your last workout on Friday night. This is when your body is primed and ready to uptake the carbohydrates and it will be most beneficial for you.
There are theoretically no restrictions on where the ketogenic diet might be used, and it can cost less than modern anticonvulsants. However, fasting and dietary changes are affected by religious and cultural issues. A culture where food is often prepared by grandparents or hired help means more people must be educated about the diet. When families dine together, sharing the same meal, it can be difficult to separate the child's meal. In many countries, food labelling is not mandatory so calculating the proportions of fat, protein and carbohydrate is difficult. In some countries, it may be hard to find sugar-free forms of medicines and supplements, to purchase an accurate electronic scale, or to afford MCT oils.[54]
Of the 28 participants enrolled in the study, 21 completed the 16 weeks of follow-up. Reasons for discontinuing the study included unable to adhere to study meetings and unable to adhere to the diet; no participant reported discontinuing as a result of adverse effects associated with the intervention. All but one of the 21 participants were men; 62% (n = 13) were Caucasian, 38% (n = 8) were African-American (Table ​(Table1).1). The mean age was 56.0 ± 7.9 years.
Your glycogen stores can still be refilled while on a ketogenic diet. A keto diet is an excellent way to build muscle, but protein intake is crucial here. It’s suggested that if you are looking to gain mass, you should be taking in about 1.0 – 1.2g protein per lean pound of body mass. Putting muscle on may be slower on a ketogenic diet, but that’s because your total body fat is not increasing as much.5Note that in the beginning of a ketogenic diet, both endurance athletes and obese individuals see a physical performance for the first week of transition. 

“As an interventional cardiologist for 30 years —and an avid runner and active person — I realized as I aged that eating less and moving more did not work for me or for my patients. The ketogenic diet resulted in a 30-pound weight loss and a dramatic increase in energy. As a past president of the Canadian Cardiovascular Society, I have been urged by medical colleagues to share my ketogenic knowledge widely. With my wife, a certified health coach, I have established a cardiometabolic clinic for obesity and insulin resistance syndromes. One of the resources we recommend is Diet Doctor.”
I recently applied for life insurance after following the ketogenic diet for about six months. I was initially quoted the lowest rate based on the fact that I have no health issues whatsoever. However, my cholesterol readings were very high so they came back and said that I had elevated total cholesterol readings of 378 which alarmed me. They have now doubled my life insurance rates because of it. Even though my total cholesterol was high everything else seems good according to this article. LDL – 272, HDL – 92, Triclycerides – 70. This all translates to an LDL/HDL ratio of slightly under 3:1 and a Triglyceride/HDL ratio of close to 1:1. I don’t know if I should be concerned that my total is well over the 300 that is sited in this article. Does anyone know?

Following a ketogenic diet puts your body into a state of “ketosis,” which is a metabolic state that occurs when most of the body’s energy comes from ketone bodies in the blood, rather than from glucose from carbohydrate foods (like grains, all sources of sugar or fruit, for example). This is in contrast to a glycolytic state, where blood glucose (sugar) provides most of the body’s fuel (or energy).
Your dietary needs change dramatically with keto. Sodium becomes a critical nutrient, as do magnesium and potassium. “At least in the initial stages of being on the keto diet, you will urinate more. One of the key electrolytes lost through urination is magnesium,” says Carolyn Dean, MD, ND, a health and nutrition expert and author of The Magnesium Miracle. “Magnesium is an energy mineral, which will help you burn fat and lose weight.”

In the absence of CHO, however, the body must shift to fat as the primary energy source. In this case, the body catabolizes stored triglycerides, which exist in abundance in even the leanest individual. In effect, the KD provokes a physiological stimulus, i.e., CHO restriction, that mimics starvation. Due to the limited ability to store or produce CHO during periods of starvation, the body thus switches to ketogenesis, the production of ketone bodies as a primary fuel source (3).
It is possible to combine the results of several small studies to produce evidence that is stronger than that available from each study alone—a statistical method known as meta-analysis. One of four such analyses, conducted in 2006, looked at 19 studies on a total of 1,084 patients.[23] It concluded that a third achieved an excellent reduction in seizure frequency and half the patients achieved a good reduction.[18]

The KD stands in stark contrast to current macronutrient recommendations for both health promotion, as well as enhancement of athletic performance (7,21). The KD is characterized by a macronutrient distribution ratio consisting of approximately 70 – 80% fat, 10 – 20% protein and <5% carbohydrate (CHO), with daily CHO intake limited to ≤50 grams. Two of the most prominent and vocal researchers of the KD, Jeff Volek, PhD and Stephen Phinney, MD, PhD, in their book The Art and Science of Low Carbohydrate Performance, recommend protein consumption of 0.6 – 1.0 grams per lb of lean body mass, a figure which almost perfectly matches the commonly recommended protein intake for athletes (i.e., 1.2 – 2.0 g/kg bodyweight) (21,26). With CHO intake radically restricted and protein within the commonly recommended range, fat becomes the primary macronutrient target for manipulation.
Basically, carbohydrates are the primary source of energy production in body tissues. When the body is deprived of carbohydrates due to reducing intake to less than 50g per day, insulin secretion is significantly reduced and the body enters a catabolic state. Glycogen stores deplete, forcing the body to go through certain metabolic changes. Two metabolic processes come into action when there is low carbohydrate availability in body tissues: gluconeogenesis and ketogenesis.[4][5]
To figure out how many fat grams specifically you want, you would take the total number of calories it takes to maintain your body weight (normally around 14-16 calories per pound of body weight). Subtract your protein calories from that number and then divide by 9 (number of calories per gram of fat). This should give you how many total fat grams you need to eat per day.

Don’t be surprised if you find yourself parched while you’re on the keto diet. Excreting all that extra water will likely cause a spike in thirst—so make it a point to drink up, Mancinelli advises. There’s no hard and fast recommendation for how much water you should be having on a keto diet. But in general, aim to drink enough so your urine is clear or pale yellow. If it’s any darker, bump your intake.
Thanks for all the info. Just found Endame Pasta at Hannafords. Two ounces (a hefty plateful) is just 9 net carbs. It’s absolutely delicious with a sauce made of mushrooms & shrimp sauteed in olive oil, a bit of butter and garlic and shredded cheese to top it off (hand shredded of course). I’d only had 6 grams of carbs today and decided to give it a try. Yum. So glad I did. Easy & quick supper.

Some people on a keto or low carb diet choose to count total carbs instead of net carbs. This makes it more difficult to fit in more leafy greens and low carb vegetables (which are filled with fiber), so you should only try that if you don’t get results with a net carb method. And, start with reducing sugar alcohols and low carb treats before deciding to do a “total carbs” method.

Typically you want to stay away from any brands that use filler ingredients like maltodextrin and dextrose, or high glycemic sweeteners like maltitol. Many low-carb products that claim low net carbs usually use these sugar alcohols. Many candies that are “sugar-free” also use these sweeteners. Avoid them where possible. These specific sweeteners respond in our body in a similar way sugar does.


Hi Cyn, The numbers are general guidelines but will vary depending on many factors, such as activity level, insulin resistance, weight and more. There is no single magic number, just conventional recommendations that are a good starting point. I will have a macro calculator coming soon that will help determine what is best for each person, but even then it’s an approximation. The only way to know for sure is to test. If keto is your goal, it’s usually best to start lower and then see if you can stay in ketosis when increasing.
This website is helpful I gained ten pounds just by snacking. I on the Keto diet with 15 carbs a day I stopped all snacking, stopped staying up late because it screws up cortisol / hormones which causes weight gain so I started going to bed at 9:30 on the dot. I typically eat one meal a day a green salad with either, chicken or prawns and simple homemade dressing . Sometimes I do a big glass of a low carb, a chocolate mocha protein drink with a nut milk and ice blended this does the trick. I never eat after 4:00. I have coffee with a little butter and drink lots of water I use Ketostix every other day to see if I’m still in ketosis. I did get foot cramps and increased sea salt intake and it stopped. I love fasting and going to yoga I feel clearer, lighter and just happier. Just keep with a program and you will see light at the end of the tunnel. Some people have great success with zero carbs. I have never tried it but read about it.
The classic ketogenic, or “keto,” diet calls for consuming a low amount of carbs, a high amount of fat, and a moderate amount of protein. But in the current study, participants induced ketosis by getting the majority of their calories from protein, a small amount from fat, and a low amount from carbs. One of the side effects of very low-calorie diets is loss of lean muscle mass, but on the adjusted keto diet in the study, participants preserved lean muscle mass. Researchers attributed the preservation of lean muscle mass to participants’ sustained RMR, and their results support those of a prior study, published in February 2017 in the Journal of Clinical Endocrinology and Metabolism.
With funding from the Laura and John Arnold Foundation, in 2012 Taubes co-founded the Nutrition Science Initiative (NuSI), with the aim of raising over $200 million to undertake a "Manhattan Project for nutrition" and validate the hypothesis.[29][30] Intermediate results, published in the American Journal of Clinical Nutrition did not provide convincing evidence of any advantage to a low-carbohydrate diet as compared to diets of other composition – ultimately a very low-calorie, ketogenic diet (of 5% carbohydrate) "was not associated with significant loss of fat mass" compared to a non-specialized diet with the same calories; there was no useful "metabolic advantage".[6][8] In 2017 Kevin Hall, a NIH researcher hired to assist with the project, wrote that the carbohydrate-insulin hypothesis had been falsified by experiment.[28][8] Hall wrote "the rise in obesity prevalence may be primarily due to increased consumption of refined carbohydrates, but the mechanisms are likely to be quite different from those proposed by the carbohydrate–insulin model".[8]
Spices have carbs in them, so make sure you are adding them to your counts. Sea salt is preferred over table salt, as it is usually mixed with powdered dextrose. Most pre-made spice mixes will have sugars added to them, so make sure you read the nutrition label beforehand to make sure you know what’s inside. If you have the choice, never include added sugar into your spice blends or food.

You may also want to try a cyclical keto diet, or carb cycling. You follow the standard keto diet for 6 days of the week, when you eat less than 50 grams of net carbs a day. But on one day of the week, you increase your carb intake to roughly 150 grams of net carbs. Doing this satisfies any carb cravings you might have, making it easier to sustain keto in the long-run. Learn more about the benefits of carb cycling and weight loss here.

There is evidence that the quality, rather than the quantity, of carbohydrate in a diet is important for health, and that high-fiber slow-digesting carbohydrate-rich foods are healthful while highly-refined and sugary foods are less so.[4] People choosing diet for health conditions should have their diet tailored to their individual requirements.[19] For people with metabolic conditions, in general a diet with approximately 40-50% high-quality carbohydrate is compatible with what is scientifically established to be a healthy diet.[19]


If you’re looking to get a jump start on your health and fitness goals this year, you may be thinking about trying the ketogenic diet. Maybe you’ve heard the phrase before — it’s a huge diet buzzword — but aren’t sure what it means. Here’s a primer: The ketogenic diet is an eating plan that drives your body into ketosis, a state where the body uses fat as a primary fuel source (instead of carbohydrates), says Stacey Mattinson, RDN, who is based in Austin, Texas.
