Thanks for this article. I just started a Keto diet so found it appropriate to my current lifestyle. Though I don’t believe your bottom line is strong enough since you simply stating that the diet is “hard to follow” and food is “notoriously unhealthy” without evidence going deeper into why those “notoriously unhealthy” foods are worse than keeping carbohydrate-heavy food that are addictive and give the body a quick sugar high for energy. I believe “hard to follow” is your opinion only, since acceptable Keto foods are found at all restaurants easily and also all grocery stores. All the foods you mention: “rich in very colorful fruits and vegetables, lean meats, fish, whole grains, nuts, seeds, olive oil, and lots of water” are all Keto-friendly. Many people have been on a Keto-diet for years. A healthy lifestyle is a healthy mindset change and making right choices – it’s not going to be easy.

“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.”
The biggest shifts in your daily habits will be how you food shop and how you cook, and recipes that are ketogenic need to be followed rather than just low-carb. You will require the healthy fats in order to get into ketosis and have enough energy without the carbs. And you will be considerably more energetic and healthier when cooking your own keto-friendly food rather than buying supposedly keto foods off the shelf.
Collagen is a type of protein that has been shown to suppress appetite[*], provide fullness compared to other proteins like whey, casein, or soy[*], help retain muscle mass[*] and even help to reduce the appearance of cellulite due to it’s ability to improve skin elasticity and thickness[*]. Refer to this article for more information on the benefits of collagen and the best way to supplement it in your diet.

Short-term results for the LGIT indicate that at one month approximately half of the patients experience a greater than 50% reduction in seizure frequency, with overall figures approaching that of the ketogenic diet. The data (coming from one centre's experience with 76 children up to the year 2009) also indicate fewer side effects than the ketogenic diet and that it is better tolerated, with more palatable meals.[18][50]


I have been on the Keto diet for approximately 2 months. I have lost 18 lbs, but have about 20 more to lose. I definitely notice certain foods, even tho they are Keto friendly stall my weight loss. I am feeling a lot better about myself already and don’t see a reason why I won’t be able to stick with this diet. However, I am stressing about what I will eat on Thanksgiving being that my family does not follow my same eating habits.


The keto diet is made up of 75% fat, 20% protein, and 5% carbohydrates. This combination enables your body to enter a state of ketosis, where the body switches from burning carbs for fuel, to burning fat for fuel. Fat, protein, and carbohydrates are called macronutrients – “macros” for short. To achieve a keto macro breakdown of 75% fat, 20% protein, and 5% carbs, you first need to know that:
Keto can promote fat loss—in the right person. For people who are sugar burners and can’t kick their sugar cravings, keto can be very helpful, because the increased fat is satisfying and curbs sugar cravings, and people eat less overall compared to their baseline diet. So, I occasionally prescribe it for weight (fat) loss, and for help with specific hormone imbalances involving insulin and stubborn fat gain because it improves insulin sensitivity. This includes patients struggling with: obesity, weight-loss resistance (assuming the thyroid is healthy), and PCOS with insulin resistance and weight gain.
Hey Michael, I would avoid it when just starting off because the carbs can add up fast and mostly of the canned whipped creams are full of additives. Once you’re adapted, I’d recommend making whipped cream from scratch and adding a dash of stevia or other keto-friendly sweetener. It’s super easy and much healthier than the canned versions (also tastes 1000x better!)
The ketogenic diet is the go-to diet for people who are looking to lose weight, lower cholesterol and blood pressure, lower their risk of metabolic disorders like type-2 diabetes, and even boost brain health (1, 2, 3, 4). But, if you are a beginner, the thought of completely turning your kitchen upside down and training your body to eat in a completely different way may seem overwhelming.

You’re transitioning. Your body is equipped to process a high intake of carbs and a lower intake of fat. Your body needs to create enzymes to be able to do this. In the transitional period, the brain may run low on energy which can lead to grogginess, nausea, and headaches. If you’re having a large problem with this, you can choose to reduce carb intake gradually.
In part, keto diet weight loss is a real thing because high-fat, low-carb diets can both help diminish hunger and boost weight loss through their hormonal effects. As described above, when we eat very little foods that supply us with carbohydrates, we release less insulin. With lower insulin levels, the body doesn’t store extra energy in the form of fat for later use, and instead is able to reach into existing fat stores for energy.
My husband is doing this diet and I was making him bean soup with sausage for dinner, but I’m reading beans are a food to avoid, even being a high fiber food is that really true? Beans were always a good I was encouraged to eat in many other diets. I’m new to keto and don’t want to hinder his process. Would appreciate your advice because I’ve already got the beans cooking. Oh they are the dry beans, not canned.
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 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.”
Although the patients underwent a total of 10 visits, the complete body composition analyses were synchronized with the ketone levels in 4 visits (Table 1; Fig. 1). Visit C-1 was the baseline visit, before starting the diet, with no ketosis (0.0 ± 0.1 mmol/L) and a body weight of 95.9 ± 16.3 kg. Visit C-2 was at the time of maximum level of ketosis (1.0 ± 0.6 mmol/L) with a body weight of 84.2 ± 18.0 kg. At visit C-3 (after 89.7 ± 19.1 days of VLCK), patients began the return to a normal diet and showed a reduction in ketone levels (0.7 ± 0.5 mmol/L) and a body weight of 76.6 ± 11.1 kg. Finally, at visit C-4, the patients were out of ketosis (0.2 ± 0.1 mmol/L) and showed a body weight of 75.1 ± 11.8 kg. All weights were statistically different from baseline levels (P < 0.05; Table 1; Fig. 1).
In a 2004 study, overweight and obese adults consumed a low-fat diet and a low-carb diet for one week each. Both diets were designed to reduce each person’s calorie intake by 500 calories per day. However, people lost more weight and body fat after the low-carb week than the low-fat week – even though the men averaged higher calorie intake during the low-carb phase.
But there is evidence that low-carb diets may increase metabolism, according to a paper published November 14 in BMJ. Researchers found that overweight adults who lowered carbohydrates and added more fat into their diets burned about 250 calories more each day than people on high-carb, low-fat diets. The study is impressive because it's the largest, most expensive, and controlled study of its kind.
“I am a medical practitioner who has type 1 diabetes. Since adopting a very low-carb lifestyle I have found that day-to-day diabetes management has become so much easier with the added bonus of normal HbA1c. As a result of smaller insulin doses, I am not tied down to strict meal times and can eat when I choose. Similarly, glucose control with exercise is far more predictable. Very low carb for me gives as near to a ‘normal’ life as someone with diabetes can get.”
In 2017, Drs. Kevin Hall and Juen Guo published what may be the first meta-analysis of controlled feeding studies that compared diets of equal calorie and protein content but differing in carbohydrate and fat content [4]. They made sure only to include studies in which all of the food was provided by the researchers. With these criteria, Drs. Kevin Hall and Juen Guo were able to ensure that confounding variables like the thermic effect of protein and subjects self-reporting their calorie intake wouldn’t muddle up the findings.

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.)
The last technique used to determine body composition in the current study was ADP (BodPod; Life Measurements Instruments, Concord, Canada), which is accepted as a convenient alternative to the water immersion method for assessing body composition. The standard BodPod protocol was followed (24), and weekly quality control tests were performed during the study period; a second calibration was conducted immediately prior to the measurement of each participant. ADP determines body volume using Boyle’s law of the pressure/volume relationship. Therefore, body volume is equivalent to the decrease of volume in the chamber with the entrance of the patient under isothermal conditions. The participants were instructed to wear a swimming suit tight to the body and a swim cap during the test to diminish accumulated air and avoid volume discrepancies. Thoracic gas volume was measured by connecting the subject to a breathing circuit. The process was repeated until a consistent measurement was obtained. Body density was calculated as mass divided by volume and corrected for lung volume. The Siri formula was used to calculate FM, FM%, and FFM (24, 25).
I believe you’re “breaking your fast” by having Olive oil in the morning. Anything over 5 calories will cause an insulin spike. I’ve been intermittent fasting (IF) 16:8 for 4 months and have just recently moved to try ketosis. I’m exercising in a fasted state. I lost 7kg of fat. Can’t comment on how effective Keto is yet, my understanding is it’s excellent for optimal fat burning.

Much of the research into low-carbohydrate dieting has been of poor quality and studies which reported large effects have garnered disproportionate attention in comparison to those which are methodologically sound.[5] Higher quality studies tend to find no meaningful difference in outcome between low-fat and low-carbohydrate dieting.[5] Low-quality meta-analyses have tended to report favourably on the effect of low-carbohydrate diets: a systematic review found that 9 out of 10 meta-analyses with positive conclusions were affected by publication bias.[5]
“I am a physician with type 1 diabetes. I have been using a low-carb, ketogenic diet to treat my own diabetes for the past 16 years. Evidence shows that low-carb diets are safe and effective. With the potential to reverse type 2 diabetes, control type 1 diabetes and even stop, slow down, or reverse complications, a low-carb diet can be life changing. Diet Doctor provides the most accurate and relevant materials for a healthy, easy and fun low-carb experience.”
The likely reason they were able to keep the weight off, researchers say, is their resting metabolic rate (RMR) was maintained, and they retained their lean muscle mass. RMR is a measure of metabolism (meaning how your body uses energy), while immobile, and it plays an important role in sustaining weight loss, according to other research, published in August 2016 in the journal Obesity.
“I have been applying low carb solutions to metabolic problems since the moment I closed the cover of Good Calories, Bad Calories. I share with my low-carb colleagues the wonderful experience of offering effective advice and seeing real results. In addition to metabolic and hormonal problems, I have more recently focused on flexible low-carb approaches for Alzheimer’s and other neurodegenerative conditions. I greatly enjoy the lively online low-carb community and rely on Diet Doctor as a resource for myself and my patients.”
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. It's unclear, however; how long these effects last.
