Here’s why. All of these effects take time, but a reasonable explanation as to why the keto diet leads to rapid weight loss is due to the loss of water weight. One of the concerns with the keto diet is the loss of muscle mass and the depletion of glycogen stores. Glycogen, which stores our glucose, also stores water, so when stores are depleted, we flush out excess water. In other words, that rapid weight loss isn’t fat, it’s just water.

A huge concern with the keto diet is the maintenance and potential loss of muscle mass. Many people will just think: hey, dummy, then just eat more protein. However, some research has shown that even if your protein intake remains constant, a low carb diet may promote muscle loss. A study from the Netherlands confirmed these findings. In the study, participants were given three diets (high carb, moderate carb, low carb) and moderate protein. The study found that those following a low carb diet experienced increased muscle breakdown. This is because when we eat carbohydrates, we produce insulin which promotes muscle growth. This is why athletes depend on carbohydrates (along with protein) to fuel their performance. When we eat carbs, the insulin release “unlocks” our muscles to let the protein in so it can do its job at building our muscles. So, when we skip the carbs all together, muscle glycogen stores get depleted, we lose out on those muscle building opportunities. Forget about high intensity training. A depleted glycogen store also means our workouts will suffer because we just don’t have enough oil left in the tank. This was a again suggested in the recent review looking at many ketogenic studies. The studies found that there was greater lean body mass loss in the ketogenic groups compared to the other diets being studied.

When can you have a cheat day on keto


This said, I do prefer low-carb balance compared to SAD. I can speculate a lot about SAD and about the non-discrimination of different carbs – like, lactose vs. fructose. It is only my opinion, that fructose has its value in the nutrition (black bears get body fat for hibernation eating fruits) yet somehow we miss to notice that naturally fructose had been available in humans’ diet only seasonally, while nowadays juices of all kinds are available year-round; not to mention fructose additives to sugar-rich products. And yes, fructose is addictive, and yes, this is part of the evolution for 200 thousand years of humans.

How many days a week should you intermittent fast


Cutting out a whole food group (or in this case, more than one) is a dietitian’s worse nightmare. It not only makes it a really hard diet to follow, but also stresses the hell out of your body and makes it work a lot harder to keep up. In a US News & World Report’s review of 2018 diet, the ketogenic diet came in last place as a sustainable means to weight loss because of its restrictive nature.

I’ve lost lots of weight on the keto diet (over 100lbs) so the comment about the weight losses being water is just absurd. And I can sustain it quite easily as long as I have the right foods in the house – just like any dietary ha it you want to maintain. The Mediterranean diet was just ranked as the #1 diet, but I bet if there were Oreos in the house, I couldn’t maintain that diet either. The “low fat” diet that we’ve all been told is so good for us is not based on sound science. It’s based on the lipids theory from the 1930s and has since been denounced due to the researcher’s omittence of any data that didn’t fit his desired model. Also, the idea that somehow because you’re eliminating a macronutrient (carbs are not a food group), you’re also reducing food intake overall, and THAT’S the reason for weight loss, is utterly false. I eat WAY more on the keto diet than I ever did when I wasn’t paying attention. My brain, body, emotions, and weight all run better on ketones than they ever did on glycogen. I actually believe that ketosis is probably the way we were designed (or evolved) to operate. Think about it… agriculture (growing carbs for eating) is only something we’ve done in the last 10,000 years. Before that, we’d eat meat all fall, winter, spring, and early summer, then gorge ourselves on carbs in the late summer to store up fat, and then do it all over again in the fall. Just because we have access to an abundance of carbs doesn’t mean that’s how we are meant to live. And for hose who think that only eating meat is horribly bad for you, look at the Inuits, the aborigines, and other people groups around the world, who until the west interrupted with colonization and exploration, loved solely on high fat animal products. And guess what, they were healthier before we showed them how easy and tasty bread was.
Thanks for the great article! As a fellow dietitian I think its challenging to stay on top of the fads and weight loss trends. The way I see it is that there are two types of ketogenic diets – lifestyle (for weight loss) and therapeutic for some of the medical conditions you mentioned above. Bottom line, the ketogenic diet is not a “natural” diet and there are serious associated side effects. I believe that people following the diet need to be supported by a team of medical professionals to ensure adequate monitoring.

[…] “ANY diet, especially one that is as devastatingly restrictive as the keto diet, is likely to encourages disordered eating behaviors. I’ve written about my own experience with, and this is a pretty scary reminder of how UNHEALTHY that world can be. I’m a big believer that everything – especially carbs – can be enjoyed in moderation and the best diet is just whatever eating pattern you find most pleasurable that also meets your body’s unique needs.” [12]  […]
Abbey, I appreciate all the work you put into this but there are a few things you missed. Not all oils are keto friendly. Vegetable oils are a huge no-no which was not mentioned. Regular mayo usually contains soybean oil which should be avoided. You also missed that foods with preservatives are a no-no which excludes some cheeses (you said enjoy all the cheese you like). Processed sliced cheese or pre-shredded cheese in a bag at the grocery store contains preservatives. Ever notice how shredded cheese in a bag never sticks to itself but when you shred your own cheese it sticks? Preservatives. Most nuts are okay but peanuts are a legume and should be consumed in very small amounts or avoided altogether. Don’t go crazy either, nuts do have carbs. I don’t eat more than a half cup a day of salted almonds. That said, you could have mentioned that getting salted nuts is ideal as you do excrete more salt and other minerals in your urine (eating keto is diuretic so attention must be paid to salt, potassium, magnesium, etc. as you did mention) so finding simple ways to add salt and other minerals is helpful. I also take a multi-vitamin daily. You mentioned you cannot do high intensity workouts. You are not supposed to do high intensity workouts as elevating your heart rate too high actually stops the fat burning process in your body. Your heart rate should be 180 beats minus your age +/- 5 beats depending on fitness level. A 40 year old obese person shouldn’t go over 135 beats/min during a workout as that is the optimal fat burning window. Higher than that and your body reverts to storing fat reserves thinking it will run out if it keeps this pace. Which bring me to metabolism. Its been long believed a high metabolism is good. A high metabolism leads to more hunger (because you’re burning glucose faster), ingesting more food, and typically gaining more weight. Slowing your metabolism down AND teaching your body to consume slow burning ketones instead of quick burning glucose puts less stress on your liver mainly and on your body in general. There’s a lot more but this is getting long so I’ll finish with this. You said this diet focuses on quantity of food and not quality. This is confusing to me….wouldn’t organic and grass-fed meats, be of better quality than non-organic and grain fed meat? (they feed animals grains to fatten them up….shouldn’t that be a huge warning sign for us?). Is food without preservatives not better quality than food with preservatives? Aren’t beverages with no sugar or artificial sweeteners of better quality than sugar/artificial sweetener-filled beverages? I’ve never seen any keto advocate advise ignoring quality foods, in fact its quite the opposite.
“Keto diets should only be used under clinical supervision and only for brief periods,” Francine Blinten, R.D., a certified clinical nutritionist and public health consultant in Old Greenwich, Connecticut, told Healthline. “They have worked successfully on some cancer patients in conjunction with chemotherapy to shrink tumors and to reduce seizures among people suffering from epilepsy.”

Today I am sharing the ultimate Keto Food List with a Free Printable Keto Grocery List. These foods will be a massive part of your new LCHF (low carb high fat) lifestyle. Before you change the way you eat, you have to modify the way you look at food. Most of the foods we’ve been told are bad for us are good. Of course, many of the foods we’ve been told are good for us (or are better options) are bad. Make sure you understand the basics behind the keto diet before you begin. That’s the only way you will be successful in making this a lifestyle change, and not just another failed attempt at weight loss.
When you consider what excessive consumption of carbohydrates (and I do consider the RDA of 250g excessive) do to the human body I find it kind of sad that nutritionists still by and large pedal carbs as a hugely necessary forerunner to being a functioning human. The sugar industry pedalled the “fat is bad” lie for decades and the introduction of low fat foods duped millions of people into becoming obese. A lot of people still don’t get, for instance, the difference between blood cholesterol and dietary cholesterol.

Slow cooking is also great for those who aren’t comfortable using a stove or an oven as slow cookers typically need minimal preparation and food is all prepared in one pot. This is also a great alternative to other books which typically rely on standard cooking infrastructure such as a stovetop. So, if you are a fan of the crockpot or simply looking to expand your ketogenic cooking repertoire, this is one of the best keto cookbooks you will find.

A study of 89 obese adults who were placed on a two-phase diet regimen (6 months of a very-low-carbohydrate ketogenic diet and 6 months of a reintroduction phase on a normal calorie Mediterranean diet) showed a significant mean 10% weight loss with no weight regain at one year. The ketogenic diet provided about 980 calories with 12% carbohydrate, 36% protein, and 52% fat, while the Mediterranean diet provided about 1800 calories with 58% carbohydrate, 15% protein, and 27% fat. Eighty-eight percent of the participants were compliant with the entire regimen. [12] It is noted that the ketogenic diet used in this study was lower in fat and slightly higher in carbohydrate and protein than the average ketogenic diet that provides 70% or greater calories from fat and less than 20% protein.
Dr. Jeff Volek performed a similar study in obese males that also looked at possible effects of resistance training in combination with the diet. In this study, Dr. Volek used a true ketogenic diet consisting of high fat and low carbohydrates. He found a comparable pattern and magnitude of change in body composition to the aforementioned study (6). He later performed another study including men and women. In this study (7) the participants were instructed to not change any physical activity behaviors and to continue with their daily lifestyle habits. The two diet intervention groups consisted of a very low carbohydrate, ketogenic diet (VLCD: 9%C: 63%F: 28%P) and a low-fat diet (58%C: 22%F: 20%P). The amount of calories that were restricted for both groups was based on the individuals’ resting metabolic rate (RMR). The women in the low-carbohydrate, ketogenic group responded much more favorably to the diet, especially in terms of trunk fat loss. Meanwhile, both men and women lost significantly more fat in the VLCD group than in the low- fat diet group. As expected, RMR decreased in both groups; however, the men in the VLCD group maintained a much higher RMR relative to their body mass than those the low-fat condition did. This has important practical applications, as most people who diet tend to have decreased metabolisms that make take a long time to recover back to baseline and in some cases may never fully return to normal.
