The data presented in the present study showed that a ketogenic diet acted as a natural therapy for weight reduction in obese patients. This is a unique study monitoring the effect of a ketogenic diet for 24 weeks. There was a significant decrease in the level of triglycerides, total cholesterol, LDL cholesterol and glucose, and a significant increase in the level of HDL cholesterol in the patients. The side effects of drugs commonly used for the reduction of body weight in such patients were not observed in patients who were on the ketogenic diet. Therefore, these results indicate that the administration of a ketogenic diet for a relatively long period of time is safe. Further studies elucidating the molecular mechanisms of a ketogenic diet are in progress in our laboratory. These studies will open new avenues into the potential therapeutic uses of a ketogenic diet and ketone bodies.
The fact that Keto-Acidosis is used as an argument against the safety of ketosis is really a grand revealer of just how ignorant and lazy some pundits are in attacking the diet. I can’t help but cringe when I think that the logic displayed here might be as lazy as “well they both have ‘keto” as their root word, ketoacidosis must be the result of ketosis”. Even more cringe worthy are the numerous cases of TRAINED MEDICAL DOCTORS advising against ketosis out of fear for ketoacidosis. Com’on society, you can do better than that.
But people who started following the keto diet noticed weight loss for a few reasons: When you eat carbs, your body retains fluid in order to store carbs for energy (you know, in case it needs it). But when you’re not having much in the carb department, you lose this water weight, says Warren. Also, it's easy to go overboard on carbohydrates—but if you're loading up on fat, it may help curb cravings since it keeps you satisfied.
The keto diet has a massive fan base that has grown at least in part due to the popular Netflix documentary The Magic Pill, which touts a trove of promising keto health benefits. But the fact of the matter is that most of the studies on the keto diet are premature. Meaning: They’re in small populations of humans, or they’re in rats. (And you are very different from a rat.)
The Ketogenic Diet is a low carbohydrate diet, consisting initially of less than 20 carbohydrates per day. Not per meal, yes, you heard me correctly, per day. It is not for the faint of heart and yes I am writing from experience. Of course I have tried it! Hasn’t everybody in America at some point who has wanted to lose weight? Does it work you ask? Of course it does! The problem is how long can you keep it up?
There is a reason why we store hundreds of thousands of calories in the form of fat in our body and only about 2000 calories in the form of glucose (with only a small amount of this useable by the brain). The reason is simple - The body prefers fat as its fuel source. Mark Sisson explains this in his article ‘A metabolic Paradigm Shift, or Why Fat is the Preferred Fuel for Human Consumption’.
Although we love them to death, our Mom’s typically have zero authority on the subject. When Mom heard you were going on a ketosis diet the first thing she did was head to google hell bent on finding any information about the dangers of the diet. Sure enough, 10 pages into google she found what she was looking for… Never mind the first 9 pages filled with information about the safety and merits of the diet.
Obesity Compared with those on a typical low-calorie diet, obese individuals on a very-low-calorie ketogenic diet lost more weight and inflammatory visceral (belly) fat in one study, published in December 2016 in the journal Endocrine. (9) It may also help preserve lean body mass during weight loss, according to an article published in February 2018 in the journal Nutrition & Metabolism. (10)
“Keto is not a great long-term diet, as it is not a balanced diet,” says Nancy Rahnama, MD, MS, an internal medicine and bariatric specialist in Los Angeles. “A diet that is devoid of fruit and vegetables will result in long-term micronutrient deficiencies that can have other consequences. The keto diet can be used for short-term fat loss, as long as it is under medical supervision.”
When a person goes off the ketogenic diet and regains much of their original weight, it’s often not in the same proportions, says Kizer: Instead of regaining lean muscle, you’re likely to regain fat. “Now you’re back to your starting weight, but you no longer have the muscle mass to burn the calories that you did before,” she says. “That can have lasting effects on your resting metabolic rate, and on your weight long-term.”
“Your liver produces ketones all the time, but the rate depends on carbohydrate and protein intake,” says Jeff Volek, Ph.D., R.D., a professor of human sciences at Ohio State University. When the majority of your diet is made up of of carbs and protein, ketogenesis slows. Replacing carbs and protein with fat will put your body into ketosis, thus ramping up ketone production. This takes about three days to induce.
Well… what are many people on a Keto diet trying to do? Lose weight right? I would guess that prior to discovering the Keto diet many of these people were caught in the trap of low fat dieting. This lead to months or years of low fat intake and consequentially low gallbladder activity. The gallbladder wasn’t needed to digest fat and so it sat idle and stones were more likely to form. Once they made the shift to a ketogenic lifestyle and their fat consumption increased upwards of 1000%, the gallbladder kicked into high gear. If the previous period of low fat dieting had caused stone formation they are going to have to deal with flushing those stones out now while on a high fat Keto diet.
The kidneys play an important role in metabolizing protein, and it’s possible that eating too much of the nutrient can have a negative impact on kidney function. While ketogenic diets are supposed to be much higher in fat than they are in protein, many keto eaters make the mistake of loading up on lots of meat, Mancinelli says. The result? You could end up eating way more protein than you actually need.
If you’re wondering why iron is at risk on a meat-based diet, hear me out. Many grain foods provide a considerable amount of iron, because wholegrains naturally contain iron in their inner layer called the ‘germ’. Another reason is that some grain products can have iron added to them during manufacturing. So, once you cut grains out, your iron status could suffer, which can lead to unpleasant symptoms like tiredness and lethargy. It can even compromise your immune system.
