You know you’re in ketosis by checking blood ketones with a hand-held ketone meter (a test for beta-hydroxybutyrate). A ketone meter can be purchased online for about $100-120, along with ketone test strips. You prick your finger and use a drop or two of blood to measure ketones. Aim for 0.5-3.0 mm. I use Precision Xtra, which can check for both ketones and glucose in the blood (useful if you’re overweight). Some people measure ketones in the urine or via a breath taste, but I’ve found them to be not as accurate.
Eating out while going keto can be tricky. Planning ahead helps you know where your next snacks and meals will come from, so you aren’t tempted to reach for an easy—high-carb—fix, like fast food. Each week, plan out everything from meals to snacks and if you’re using an app, go ahead and fill in your estimated macronutrients ahead of time. This will help you get an idea of your overall intake, so you can make adjustments to reach your daily goals more easily. Get started by planning to make these 10 keto recipes so good you’ll never know you’re on a diet.
a) Why do I need to eat dietary fat during the keto diet if I have plenty of adipose tissue (as is currently the case) that can equally well be used as a source of energy? In your article you simply say that dietary fat is necessary for the keto diet to work, by I can’t see any explanation for that. Eating fat while I already have plenty of it available seems a bit counterintuitive.
Hi Jenn, I would not recommend the medication as it is not going to address the root cause of any sort of dysfunction that may be leading to what we are seeing on the lab. When I see elevated cholesterol levels with good Triglyceride:HDL ratios, I most commonly see an underlying thyroid issue with low free T3 levels. I would want to test your thyroid in detail and you may need some additional thyroid hormone support. With very high HDL over 90, I will also see chronic infections and food sensitivities as an issue.
A Ketogenic diet is one that is high in healthy fats and proteins, and extremely low in carbohydrates.  Typically, it takes around 100g of carbohydrates per day to keep up with the average person's brain and organ function.  When you eat between 20-50 g of net carbohydrates (total carbohydrates – fiber) your body has to switch over to using fat to fuel itself instead of carbohydrates.  This process is called Ketosis, and it's a perfectly natural state of humans to exist in.
Several studies have investigated the potential of LCD or KD on weight loss. For example, Brinkworth et al. (2) compared one year of low-fat (LF) vs. LCD diet in adults with abdominal obesity. Subjects were randomly assigned and diets were isocaloric, with moderate energy restriction. Both groups realized significant weight loss, however, there was no significant difference between groups, suggesting that a LCD was equally effective as a LF diet.
Obesity is a preventable disease that plagues all the countries of the world, affecting 650 million of its habitants [1,2,3]. In the fight against obesity, a very low-calorie ketogenic (VLCK) diet has consistently been shown to be a useful tool [4,5,6]. Indeed, recent studies from our research group demonstrated that a VLCK diet induces more weight loss than a standard low-calorie diet after 1 and 2 years of follow-up [6]. Among the beneficial effects, the VLCK diet was able to preserve muscle mass, muscle strength [4] and resting metabolic rate [7] and the weight loss was due to fat mass and visceral fat mass [4]. However, obesity is more than an excess body-weight problem [8]. This metabolic disorder is associated with several co-diseases, such as type 2 diabetes, cardiovascular and neurological disorders, and cancer [9,10,11]. Moreover, overweight/obese subjects usually experience a strong desire to eat coupled with a lack of control over eating [12] and suffer from emotional distress and a decrease in quality of life (QoL) and sleep and sexual function [11]. In this regard, few studies have evaluated the effect of weight-loss therapy on the food craving and well-being parameters in overweight/obese subjects.

My Husband and I started doing Keto July 2018. We got over weight after we got out of the Marine Corps. It has been hard to workout because I became disabled, but my diet was not good. After our friend Amber recommended your site and support group, we found a lot of helpful information to get us started on a successful journey. So far it’s been one month and we have lost 18 pounds each!

Various mechanisms may explain the variations in body water. For example, glycogen depletion induced by VLCK diets could cause a marked increase in diuresis, given that glycogen is usually stored together with water (39, 40). Water loss might also be associated with ketonuria, because ketone bodies increase the renal sodium and water loss as a result (39, 41). These assumptions seem reasonable considering that the peak water loss coincides with the phase of maximum ketosis. However, the mechanisms explaining the diuresis observed with VLCK and with most hypocaloric diets are not known at present (30). Contrary to previous observations (42, 43), DXA analysis evidenced a maintenance in bone mineral density in the current study.
“After struggling with weight my entire life, I was pointed in the direction of a low-carb diet by a group of other physicians — and it changed my life. As a family physician, it became clear to me how many of my patients could benefit from this lifestyle in so many ways. I spent time training with other doctors who had been practicing nutritional medicine with their patients for years, and learned how best to help my own patients. This is my passion, and being able to help change patients lives in this way is incredibly rewarding.”
“We know that when we have fats in our diet like MUFAs, they not only fill us up but keep cholesterol levels lower,” says Keatley. Olive oil is great for light sauteing, using in dressings, or drizzling over cooked meats or vegetables as a finishing oil. One tablespoon (tbsp) offers 119 calories and 13.5 g of fat, only 2 g of which are saturated fat, according to the USDA.
By discriminating the components of the FFM as determined by DXA, it was observed that these variations were mainly due to changes in lean mass, whereas bone mineral content remained unchanged from baseline (0.003 ± 0.066 kg at visit C-2; −0.018 ± 0.066 kg at visit C-3; and −0.028 ± 0.066 kg at visit C-4; P > 0.05). Given that DXA technique is unable to discriminate the composition of lean mass, the question was raised as to whether the observed reductions in lean mass were at the expense of muscle mass or body water content. Therefore, further analysis was performed by MF-BIA , which is able to discriminate these 2 variables. Remarkably, the measurements performed by MF-BIA showed that the initial loss of FFM at visit C-2 (−3.1 ± 1.5 kg) was mostly due to total body water loss (−2.3 ± 1.1 kg), both intra- (−1.5 ± 0.7 kg) and extracellular [−0.8 ± 0.5 kg; Fig. 3(B)], probably because of the intense diuresis that occurs in the first phase of any VLCK diet. In subsequent visits, a slight recovery of intra- and extracellular water was observed, similar to the recovery observed with total FFM. This means that reductions attributable to muscle mass were, depending on the method used, around 1 kg throughout the 4-month study; only 5% of the total 20.2 kg of weight lost was FFM.
But what does the science say? Results are mixed. In one Spanish study of 20 obese adults, participants were put on a low-calorie keto diet and lost an average of 40 pounds over four months. Another small experiment had a similar outcome. In a six-month Experimental & Clinical Cardiology study of 83 obese adults, those on the keto diet lost an average of 33 pounds, while lowering their bad (LDL) cholesterol levels and increasing their good (HDL) cholesterol.
We know now that plaque formation is a culmination of inflammation at the plaque formation site along with a white blood cell mediated interaction between calcium, cholesterol and other biological substances. In fact, it is thought that cholesterol is actually used by the body as a kind of internal bandage when our arterial lining becomes damaged by inflammation. This means that cholesterol build up in the arteries may actually be a protective mechanism.
“I have been a supporter of a low-carb lifestyle that includes intermittent fasting for myself and my patients for years. I am part of our health systems Medicine Residency program. I teach physicians-in-training and medical staff to utilize low-carb and keto dieting to improve the health of their patients and reduce their need for medications. Diet Doctor is an excellent resource for patients and physicians to help patients help themselves to promote a healthy lifestyle.”
Ketosis was determined by measuring ketone bodies, specifically β-hydroxy-butyrate (β-OHB), in capillary blood by using a portable meter (GlucoMen LX Sensor, A. Menarini Diagnostics, Neuss, Germany; sensitivity <0.2 mmol/L). As with anthropometric assessments, all the determinations of capillary ketonemia were made after an overnight fast of 8 to 10 h. These measurements were performed daily by each patient during the entire VLCK diet, and the corresponding values were reviewed on the machine memory by the research team to control adherence. Additionally, β-OHB levels were determined at each visit by the physician in charge of the patient. Glucose, insulin, HbA1C were performed using an automated chemistry analyzer (Dimension EXL with LM Integrated Chemistry System, Siemens Medical Solutions Inc. (Tarrytown, NY, USA). Thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3) were measured by chemiluminescence using ADVIA Centaur (Bayer Diagnostics, Tarrytown, NY, USA). The overnight fasting plasma levels of ghrelin and leptin were measured using commercially available ELISA kits (Millipore, Burlington, MA, USA). The fasting plasma levels of dopamine was tested by high pressure liquid chromatography (HPLC; Reference Laboratory, Barcelona, Spain).

For some, ketosis can cause more negative than positive side effects. Dorena Rode, a 52-year-old author, and speaker from Occidental, California, tried the diet for a month and experienced heart palpitations and dizziness. Unlike Drew, Rode says her cholesterol increased from 192 to 250 mg/dL after she introduced more fat into her diet. (Less than 200 mg/dL is considered desirable, while anything over 240 mg/dL is considered high.)
Don’t stick to chicken and steak just because you’re comfortable cooking them. Make dinner time the place where you can try new meats and recipes that increase your keto recipe resources. “At lunch and dinner, you can be creative and experiment,” Weaver says. “Just focus on cooking meat—pork, chicken, lamb, beef, or seafood. Meat is rich in iron and fish contains omega-3 fatty acids and vitamin D. Use only organic oils, such as avocado oil, coconut oil, and olive oil.” Read up on these things you have to know before starting the keto diet.

Hi Sam, it won’t work. You will be incredibly hungry and you won’t have any energy. The idea of the keto diet is to get your body used to use fat to burn energy not carbs. Since you won’t be eating carbs energy has to come from “something” and it can’t be protein. I can’t recall what happens when you have too much protein when doing Keto but it was something scary. In general, I do not recommend the Keto diet without some sort of supervision by your doctor or nutritionist that can watch your process and progress.
The ketogenic diet, or keto, relies on using your fat as fuel, instead of glucose from carbohydrates or protein. Simply put, the daily ketogenic diet consists of 75 percent fat, 20 percent of protein, and a teeny allotment of carbohydrates, about 5 percent. This balance of macronutrients is intended to put your body in a state of ketosis, which suppresses the release of insulin and blood glucose levels. The benefits of ketosis to your health are improvements in biomarkers like blood glucose, reduction of blood pressure and decreased appetite due to fullness linked to consumption of fats.

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.
The VLCK diet was used because of its ability to produce a rapid and well-tolerated weight loss with a ketogenic phase that lasts 60-90 days and a final result of 20 kg of weight reduction at 4 months. The rapid reduction in weight is the probable explanation of the positive effects of this dieting approach, which are evident 1 and 2 years later (12, 13). Four different stages occurred with the VLCK diet used: a basal stage with obese body weight and no ketosis, a second stage with extreme ketosis and marked body weight loss, a third stage with body weight loss and declining ketosis, and a fourth stage with weight loss and no ketosis. Body composition was studied with the 3 techniques at each of these stages.
The targeted keto diet follows the basic ketogenic plan until right before a workout. In a traditional ketogenic diet, you focus on proteins and fats in meals. Reducing carbohydrates reduces the energy available from foods. When your body cannot get energy from food sources, it turns to fat stores. It is unclear why this diet helps children with epilepsy, but for those who want to lose weight, the benefit is obvious. You burn off body fat on a ketogenic plan.

The nerve impulse is characterised by a great influx of sodium ions through channels in the neuron's cell membrane followed by an efflux of potassium ions through other channels. The neuron is unable to fire again for a short time (known as the refractory period), which is mediated by another potassium channel. The flow through these ion channels is governed by a "gate" which is opened by either a voltage change or a chemical messenger known as a ligand (such as a neurotransmitter). These channels are another target for anticonvulsant drugs.[7]
There is a lack of evidence of the usefulness of low-carbohydrate dieting for people with type 1 diabetes.[1] Although for certain individuals it may be feasible to follow a low-carbohydrate regime combined with carefully-managed insulin dosing, this is hard to maintain and there are concerns about potential adverse health effects caused by the diet.[1] In general people with type 1 diabetes are advised to follow an individualized eating plan rather than a pre-decided one.[1]
Following a very high-fat diet may be challenging to maintain. Possible symptoms of extreme carbohydrate restriction that may last days to weeks include hunger, fatigue, low mood, irritability, constipation, headaches, and brain “fog.” Though these uncomfortable feelings may subside, staying satisfied with the limited variety of foods available and being restricted from otherwise enjoyable foods like a crunchy apple or creamy sweet potato may present new challenges.

Hi Stacey, I can’t give medical advice and definitely recommend following your doctor’s recommendations. You can ask him/her if low carb would be better suited for you. Also, you may want to double check with him/her if the kidney concern was related to high protein, because that is a common misconception about keto – it is not a high protein diet/lifestyle.
Supporting these results, Naude et al. (15) found a similar outcome in obese adults with and without type 2 diabetes. This meta-analysis of 19 randomized, controlled trials compared dietary interventions using standard CHO recommendation (i.e., 45 – 65%), low-carbohydrate/high protein (LCHP) and low-carbohydrate/high fat (this group, although not specifically stated, met the criteria for KD). Results demonstrated significant weight loss among all groups in the short-term (3 – 6 months) and long-term (1 – 2 years), with no significant difference among dietary interventions. The authors concluded that weight loss interventions using CHO restriction are equally effective as isocaloric diets of standard CHO recommendation.
Make things yourself. While it’s extremely convenient to buy most things pre-made or pre-cooked, it always adds to the price per pound on items. Try prepping veggies ahead of time instead of buying pre-cut ones. Try making your stew meat from a chuck roast. Or, simply try to make your mayo and salad dressings at home. The simplest of things can work to cut down on your overall grocery shopping.

Dieters and healthy eaters are programmed to get vegetables at every meal in order to reach their daily plant quota, but Mancinelli says the cumulative total can blow through your daily net carbs. “They have vegetables in their breakfast omelet, big salads, snack on celery and carrot sticks, and have big sides of leafy greens in place of rice at dinner,” she says. “The carbs in all those vegetables add up. A few carbs here and there with cheese, nuts, and seeds, and you can really miss the mark for ketosis.” Start smart by cooking with these low-carb vegetables.

I have pancreatitis, well controlled, which is the way I want to keep it. The biggest difficulty I have with keto is this: I eat a small portion of steel cut oats in the morning. When I don’t, within two days , I start having bleeding, dark in colour. My endrocrinolagest feels that I need the roughage in the steel cut oats to replete the bowel lining. I have great difficulty loosing weight, always have, even though I eat very clean, no junk food, never eat out, don’t like pop, don’t crave sugar, cook all food fresh. Any comment? Willing to try anything you can suggest.


My macros are 10-15% carbs, 20-25% protein and 60-70% fat, and my calories are between 1300 to 1500 but I'm still not in ketosis and only lost 1 lb so far. I'm making sure that my net carbs are below 25g. My fat usually ranges between 90g to 120g, and my protein ranges from 60g to 90g. for the past 5 days, test scripts are showing that i'm in small ketosis. It's not going up. My husband on the other hand is in Large Ketosis and lost about 5 lbs. He just started 1 day before me. Any advise to get int Ketosis and lose weight.
Ketogenesis results in the production of ketone bodies, a product of fatty acid catabolism performed primarily by the liver, in the absence of adequate CHO availability. Three primary ketone bodies are produced; acetone, acetoacetate and β-hydroxybutyrate. Even though trace amounts of ketones are always present in the blood, it is only during periods of inadequate CHO availability that significant ketone production will occur. This accumulation of ketone bodies in the blood is commonly referred to as ketosis.
Prolonged ketosis and large buildups of ketones can be dangerous, but VLCDs intentionally bring on mild ketosis. At a certain level, ketosis brings on desirable changes that facilitate safe weight loss and keep important body processes working properly while getting so few calories. When your body is using fat for energy, you may be losing weight, but your brain can be starving because it primarily uses glucose, or carbohydrates, for energy. However, ketones can cross the blood-brain barrier and supply most of your brain's energy needs, according to Wim Saris, a researcher writing in the November 2001 "Obesity Research" journal. Without ketones fulfilling this role, your body will begin to break down amino acids, your protein building blocks, into blood sugar. This can cause you to lose lean muscle mass while on the VLCD.
A randomized control study in 2017 examined the effects of a ketogenic diet combined with Crossfit training on body composition and performance. Results from this study concluded that subjects following a low-carbohydrate ketogenic diet (LCKD) significantly decreased body weight, body fat percentage and fat mass compared to those in the control group[*].
“I am an anesthesiologist who managed to lose weight and reverse my pre-diabetes a few years back. I now advocate the low-carb diet and lifestyle to all patients, colleagues and friends. Diet Doctor is a comprehensive one-stop resource which I highly recommend. Almost every patient I anesthetize has metabolic issues, and the situation is difficult as the diet in India is primarily carbohydrate based. I have successfully helped friends and patients reverse their type 2 diabetes.”
