Carbohydrate facts: Simple = bad, complex = good? Carbohydrates provide energy for the body, but the health benefits they offer depend on the type of carbs we consume. Complex carbs, found in brown rice, for example, contain more nutrients than simple carbs, such as white rice. Refined carbs, such as sugary drinks, are best avoided, as their nutritional value is low. Read now
The relation between a high fat diet and cancer is not conclusive. Recent epidemiological studies (17,58–60) could not explain a specific causal relationship between dietary fat and cancer. It has been found that altered energy metabolism and substrate requirements of tumour cells provide a target for selective antineoplastic therapy. The supply of substrates for tumour energy metabolism can be reduced by dietary manipulation (eg, ketogenic diet) or by pharmacological means at the cellular level (eg, inhibitors of glycolysis or oxidative phosphorylation). Both of these techniques are nontoxic methods for controlling tumour growth in vivo (61). Sugar consumption is positively associated with cancer in humans and test animals (58–61). This observation is quite logical because tumours are known to be enormous sugar absorbers. It has also been found that the risk of breast cancer decreases with increases in total fat intake (16). Further studies on the role of a ketogenic diet in antineoplastic therapy are in progress in our laboratory.
It is completely wrong to discuss “average lifespan”. The average lifespans of pre-industrial peoples is heavily reduced by infant and early childhood mortality, which has nothing to do with lack of fresh fruit. Once you remove this bias in the numbers, pre-industrials can have lifespans almost as long as ours. And usually without many of the degenerative diseases that bother our middle and old ages.
Technically speaking, you're in ketosis when your blood ketones are higher than 0.5 mmol/L, but the optimal level for fat-burning purposes is 1.5 to 3 mmol/L. Nisevich Bede says that seasoned keto dieters report that they can actually feel a difference in this state, citing that they're less hungry and experience mental clarity once they reach ketosis.
Insulin resistance is caused by several mechanisms, one of which is chronically elevated insulin levels. So what increases insulin levels? Mainly sugar. A poor nights sleep can do it too, but sugar is a big one. This can be sugar that is part of our diet or carbohydrates that are broken down to glucose or other simple carbs. Proteins put together with fats can also be converted into sugar, a process called gluconeogenesis. However, it is really the effect of dietary refined sugars and starches (flour) causing blood sugar and insulin spikes (not protein). These insulin spikes from added sugars and flour are then often followed by a blood sugar crash, leading to a sense of discomfort, even sweating, and usually a craving for more high-carb foods.
I think you should give Keto a 3 month trial. You will notice that any inflammation you have will disappear. The best bonus for me is that I now only eat one meal per day. I’m 57 like you. I figure I save 1 hour per day in food prep, eating and shopping. By the time I’m 100 I will have spent 15,000 fewer hours messing with food. That’s like adding 3 years to your life!
84 obese diabetes patients were randomized to either follow a ketogenic diet (<20 g Carbs/day) or a reduced-calorie, low-glycemic diet (55% calories from carbs, 500 kcal deficit). The ketogenic group had greater improvements in HbA1c, body weight, and HDL cholesterol compared to the low-glycemic group. Diabetes medications were reduced or eliminated in 95.2% of the ketogenic group and 62% of the low-glycemic group.
You sound weak I have given up all carbohydrates and fast acting insulin and had no issue with it ( real food is so delicious and satisfying)… and I don’t miss bread pasta and sugar at all… your mind is poisoned. It also has an added side effect , I now have no fat on my body. You uneducated money grubbing doctors and the sugar industry are the real problem here. My endocrinologist didn’t even bother to tell me about nutritional ketosis at all. I eat 80 to 85% good saturated fats out the 4000 calories I consume each day… not that difficult getting rid of crap sugar and carbs… these “doctors “ are lying to us and no one cares! It’s really disgusting …. I have no problem living without sugar…. and no studies done at all.. what the hell are these doctors doing, it seems pretty obvious to me$$$$.
Fat (and the ketones produced from fat) are a readily available source of fuel. Once someone is fat adapted and in ketosis, they will find they can easily go hours (even days) without food and not have drastic energy level swings. And if someone is looking for a non caffeine, non-sugar 'pick me up' while in a ketogenic state, then supplemental ketone salts are the perfect answer.
The ketogenic diet is a high-fat, very-low-carb diet plan. The goal of the diet is to reach a “ketosis” state. The more restrictive you are on your carbohydrates (less than 15g per day), the faster you will enter ketosis. Once in this state, rapid weight loss begins. Research does indicate that the ketogenic diet is most effective in weight loss by reducing visceral (body) fat.
As for individuals with type 2 diabetes, Dr. Galati says, "a very low carbohydrate diet could be tolerated, albeit with extreme caution. Transitioning to a ketogenic diet will require several lifestyle changes as well as careful monitoring of both your food intake and glucose levels and adjustments to your medications. Also, you should increase your water consumption."
Roxy, I started at 283 in February 2018. I am now 212 with the hope to make 100lbs lost by Feb 2019. KETO is a life choice and comes with changes that have to be made! My mantra at difficult times in the beginning was to be different i must do different! Also most modern foods pizza and tacos can be adapted to keto way of eating. Just takes research and a little planning. I have tacos weekly!
“I’m no longer on insulin, and I have cut down my medications due to keto. I never had to deal with trying to find a spot to inject or having to deal with bruises on my belly,” she says. “I know this may sound silly, but I have a picture of my old insulin syringes in my wallet. I look at it to remind me of what I had to do before keto. It grounds me, and when I have days of self-doubt, I remind myself how far I’ve come.”
I told the nurse that I would not take the medications, and I would manage it with diet. She looked at me skeptically, and said “I would not recommend that.”. They had me scheduled for a follow up in a month and a half, so I told her that I would do my own thing for that time, and if my numbers did not improve, we could discuss the medication further.
Also recognizing what worked 6 months to 1 year ago may not work today. Our bodies change over time and we have to adapt to those changes. So many factors affect your blood glucose levels; you will face hormonal changes, stress related changes, and your pancreas may not be working as well today as it did a year ago and we wouldn’t expect it to. Just as the heart of an 18 year old person is much stronger than it will be at the age of 50 years of age, your pancreas’ function will decline with age with the normal aging process. Many of my patients throughout the years have came to me feeling so defeated because now they have to go on medication or insulin. They are so relieved to hear this may not be due to anything they have caused by overeating or weight gain, it may be just the unfortunate natural progression of diabetes. Until we discover cures for the different types of diabetes, this is what we face.
The targeted keto diet is popular among athletes and active individuals who live a keto lifestyle but need more carbs. It allots an additional 20-30 grams of carbs immediately before and after workouts to allow for higher-intensity exercise and enhanced recovery. (The total carb count comes to 70-80 grams per day.) The best options include fruit, dairy or grain-based foods, or sports nutrition products. Because the additional carbs are readily burned off, they don't get stored as body fat.
While these findings are preliminary, in one study of mice, the keto diet helped reduce anxiety. The research suggests this could be due to the protective brain benefits of intake of healthy fats and low levels of sugar. A follow-up study found that mice exposed to a ketogenic diet while in utero showed less susceptibility to anxiety and depression than mice born to mothers who were not on the keto diet. Here’s what it’s really like to follow the keto diet.
Although various short-term studies examining the effect of a ketogenic diet in reducing the weight of obese patients have been carried out (10), its long-term effects in obese subjects are not known (15). Therefore, the purpose of the present study was to investigate the long-term effects of a ketogenic diet on obesity and obesity-associated risk factors in a large population of obese patients.
This was a great read. I aim to restrict carbs always because I believe most are why the American population is obese. I would very much like to hear more about carb restriction excluding the discussion on processed meats and processed high salt content foods because I consume neither. I also don’t consume dairy or eggs. So can you provide some substance.
It has been found that a sugary diet is the root cause of various chronic diseases of the body. A recent study (35) showed that sugar can accelerate aging. Several recent studies (36,37) have pointed to the fact that a diet with a high glycemic load is independently associated with the development of cardiovascular diseases, type II diabetes and certain forms of cancer. Glycemic load refers to a diet of different foods that have a high glycemic index. Glycemic index is a measure of the elevation of glucose levels following the ingestion of a carbohydrate. The classification of a carbohydrate based on its glycemic index provided a better predictor of risk for coronary artery diseases than the traditional method of classification of carbohydrate into simple or complex forms (38). In other studies (38–46), it was shown that the risk of dietary glycemic load from refined carbohydrates was independent of other known risk factors for coronary diseases.
According to Dr. Cabeca, “Fasting is a key aspect of a healthy diet and has many anti-aging effects.” In particular Dr. Cabeca recommends fasting to women during or after menopause due to it’s anti-aging effects. For example, a 2016 study published in the Journal of the American Medical Association found that when women went 12.5 hours between dinner and breakfast (a common form of fasting), the overnight fast seemed to help improve immune system functioning to the point that it reduced their risk for breast cancer.

As someone who is prediabetic, Keto has been a godsend! I thought I was just a glutton, but now I’m certain I am actually insulin resistant. I am on Keto and can manage half a cup of blackberries without coming out of ketosis, but almost any other carb/sugar and I become a mindless food consuming zombie. I literally feel like I have zero control over my ability to stop eating. Also before trying Keto, if I was not able to eat constantly throughout the day I became grumpy and tired. Like none tired where it felt like I had lead running through my veins. On Keto, I can go a good 5-7 hours without eating and I don’t feel off at all. I am hoping to lose weight, but mostly I do not want to become diabetic and my problem is that I am insulin resistant. I do plan eventually to eat more black beans, vegetables and fruits again. Maybe a little chocolate on holidays and cake and ice cream on my
Thank you for your objective review of the Keto Diet. I am not overweight but decided to try the Keto lifestyle because I have a lot of inflammation issues, including asthma and osteoarthritis. I had also been experiencing uncomfortable intestinal issues. I have been following the Keto lifestyle for 4 1/2 weeks, and I feel so much better- especially my stomach! I am eating a ton of leafy greens, broccoli and cauliflower. I am also enjoying Brussel sprouts, whole avacados and zucchini. I think the reason this is working well for me is because my body chemistry loves all the vegetables, good fats and protein. I also think that taking away sugar has had a big impact on how I feel. I’m just not eating grains and sugar. lots more veggies, berries, and consciously incorporating healthy fat. My stomach is flat again, and I have no more bloating or constipation. I have only lost 5 pounds, but I think my system is clean and operating better than it has in years. My point is that every person’s body chemistry is different. The Keto lifestyle seems to be what My body needed to feel my best. I did experience “the Keto flu” about a week into it, but it was short lived. I think that to be successful it is really important to eat a wide variety of veggies and good fats every day.
Losing essential micronutrients is another concern raised by keto diet skeptics. People say eating a diet based on fat and protein from animal sources means losing those micronutrients found in higher-carb grains, legumes, fruits, and vegetables. Some also claim low-carb diets contain too little fiber, and thus may cause long-term constipation. That’s inaccurate.
Many people and even some doctors confuse nutritional ketosis with (diabetic) ketoacidosis. Ketoacidosis occurs in uncontrolled diabetes when the pancreas cannot secrete enough insulin to exert its action in cells, so blood glucose levels and blood ketones both skyrocket to dangerously high levels. Ketoacidosis has nothing to do with nutritional ketosis which is when ketones are produced from all the dietary fat you’re relying on and can thus keep your blood sugar levels under control at low and stable levels.
The walking around part is not true in my experience, exercise alone will not help an obese person. I’ve been doing Keto and most things I’ve read have come true, I found this article to be unbiased. I will say this however, I agree I too have been eating many green veggies and the bad stuff I do use I use very little for flavor (like bacon) what I found that is utterly ridiculous on the part of the folks that did the diet rankings was saying Keto was unsustainable. The way I feel from being on Keto is insanely well. I want to keep eating this way! Unsustainable its the only diet I can do intermittent fasting on. I was type 2….
What makes the the ketogenic diet unique among low-carb diets is that it’s characterized by a drastic reduction in carbohydrates (usually less than 30–50 grams per day, depending on individual goals) and also a significant increase in fats, as opposed to protein. The goal of the KD is to enter the metabolic state of ketosis, which happens after a few days of strict carbohydrate restriction.
After reading that article I have to say that the “USC experts” are full of it. It’s the usual scare stuff that the mainstream docs and dietitians trot out to attempt to discredit LCHF and keto diets. There’s no reason why a keto diet should be any worse for bone health than any other diet provided it has adequate calcium, phosphate and Vit K2 and you have good Vit D levels. As for the recommendations of dietitians – eat lots of healthywholegrains and “vegetable” oils but no saturated fats – we know what the long-term results are of that: diabetes, heart disease and osteoporosis.
Hello everyone. I was diagnosed as a diabetic in 2010. I followed the ADA diet while taking metformin and lnsulin and could never get by glucose readings below 135. Most mornings it was at 175 or higher. In mid 2017 I had to find a new doctor. I ran out of meds in Semtember of that year but could not find a doctor due to not accepting new patients and or my health insurance. I broke my foot at work on the last workday in December. Was instructed to stay off foot for 6 to 9 months . In the mean time I finally got to see my new family practitioner on March 28 2018. Represcribed meds and ordered blood work. A1c was ar 14.1. With my new glucose meter my readings were 375. Due to basically being bedridden while my foot heals I was concerned about diabetic complications an weight gain as I was already overweight. After doing research online I learned about the keto diet. I began the diet on 3/29 /2018 along with intermittent fasting. I weighed 265#. As of 4/26/2008 I am at 245#. My glucose readings have been on average 73 to 98 and a couple of times 111. I stopped all my medication about a week ago just to see if they would increase. They have not so far and I check 4 times daily. I sleep better and do not crave sweets. I feel full . The first two weeks were tough but now I can go 2-3 days without being hungry. I am looking forward to the results of my next blood test in June. This diet fits my circumstances and I do plan on to exercise when I am able to. I want to reach my weight to height ratio also. When I achieve this goal I may tweak my diet at that time but for right now that is what is working for me. I may never be able to eat some of the things I used to but considering the complications of diabetes it is one hell of incentive for willpower to stay on the diet.I will repost again after my next blood test or if there are any significant changes.
Ketosis is different, because, when in the state of ketosis, the brain will prefer ketones over glucose. For the dieter this is good! The body will not have to break down protein for energy. In turn the body will be forced to use its fat reserves, a.k.a. your love handles, for its energy. This is why a low-carb diet is such a good method of dieting.
It takes more work to turn fat into energy than it takes to turn carbs into energy. Because of this, a ketogenic diet can help speed up weight loss. And since the diet is high in protein, it doesn't leave you hungry like other diets do. In a meta-analysis of 13 different randomized controlled trials, 5 outcomes revealed significant weight loss from a ketogenic 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)
He also told me that I was in horrible shape, that I would need a lot of medication, and that because I was T2, insulin would do nothing for me. I still remember walking out of the building after. I felt like shooting myself. My brother had just gone blind from retinopathy 2 months earlier. There was no hope for me. High numbers were inevitable. Complications were inevitable.
Cyclical ketogenic diet (CKD): If you find it difficult to stick to a very low-carb diet every day, especially for months on end, you might want to consider a carb-cycling diet instead. Carb cycling increases carbohydrate intake (and sometimes calories in general) only at the right time and in the right amounts, usually about 1–2 times per week (such as on weekends).
Fat accumulation in the liver is commonly associated with prediabetes and type 2 diabetes. In serious cases, fatty liver disease can damage the liver. Doctors test for the condition by measuring levels of liver enzymes using blood tests. “These enzymes were significantly reduced after one year in the clinical patients, indicating less risk of developing fatty liver disease,” Dr. Phinney says of the diabetes study. If you’ve been told you’re at risk for fatty liver, you may want to give this diet plan a try. Before you embark on any new eating plan, arm yourself with knowledge. You’ll want to read this: 11 hidden dangers of the keto diet.
I have been on a low carb diet for over 2 years. I was diagnosed a diabetic with a blood glucose over 400 mg/dl and an A1C of 12. I tried my doctors recommendations for about a year and took all the medications they told me to take. not much changed. they wanted to put me on insulin after a year. I told my doctor that I thought I could control my condition with diet and he said, “you are to far gone for that”.
WOW. I guess I must be a very special, highly motivated patient then. I, of course, would never have said that about myself. My high motivation is trying to get over the hatred of food that being Diabetic gave me. I don’t feel that way anymore, and am finally happy cooking, again. (My doctor DID tell me exactly that, BTW. Even to the extent of telling me to not include the tsp of agave that I was having in my coffee once a day because sugar is sugar.)
This type of information has also been on the Internet. When I first saw what the consequences could be if this is planned by the person following the Keto diet as being for a lifetime thing, I immediately sent the article to my brother & his wife . They’ve been on this for some time & have lost weight on it. All good, but may not be well for my brother, who has one kidney. It was removed because it was no longer functioning at full capacity.
The keto diet may also be beneficial for adults with epilepsy, though the Epilepsy Foundation notes that it’s less frequently recommended for this group because it is so restrictive and difficult to stick with. (1) One study, published in May 2016 in the journal Epilepsy & Behavior, found the diet reduced the frequency of seizures for many study participants, 7 percent of whom were seizure-free at the four-year mark. (2) And though it wasn’t the goal for this study, nearly 20 percent of the participants lost weight while following the diet.
I was a Corpsman (not a corpse-man as some recent somewhat fanatical president would say), and I can tell you many stories of Marines and Sailors who maintained restrictive diets (aka picky eaters). Most obvious was lack of sustaining energy (hypoglycemia) at mile 15 (with 80lbs of gear including a 6.5lb rifle and 200 rnds of ammo, etc.) and depletion of essential vitamins, electrolyte imbalance. They were always the first to collapse and have to hear me scold “see I told you so.” An IV of D5W usually does the trick (D is for dextrose, OMG!)
The comments defending the keto diet suggest that the individuals are successfully using the keto diet to help them maintain a healthy weight and a healthier A1C level. The individuals also suggest that they view it as a way of life rather than a diet. This is good news for many of us who are facing the question of whether it will be helpful and necessary to reduce carbohydrate intake to keto producing levels in order to halt or reverse the onset of type II diabetes. I think like those individuals, Tami is speaking from her own personal experience where she had success losing weight, but had difficulty maintaining the keto diet long-term. I am sure that though you have been successful, you can understand that there are many who might find it difficult to maintain. I too have been given very bad guidance by Medical Doctors who lean on old Med School information to practice medicine rather than continuing to broaden their knowledge base and learn more about nutrition. I cannot get back the 20+ years of suffering with a debilitating disease that could have been cured because my doctors were not well informed or willing to listen to information that disagreed with their limited knowledge base. Those years are gone and the destruction to my body is not reversible. So I understand the anger you feel toward a system that isn’t working in the best interest of the patient. But I think that expressing anger toward those who disagree with our personal experience, is not solving the problem. Hopefully we can change the ADA guidelines by respectfully urging them to reconsider their position based on the sheer volume of the comments they receive from successful people like you, who are living the keto diet lifestyle and living better. I commend you for becoming your own best health advocates. Thanks for your encouragement and your passion. And thanks to Tami as well for sharing her personal experience and the information she had collected. We all have to be true to what we believe and we all have a right to come to our own conclusions. It is good to know that there are success stories out there. I wish you all good health and continued success. I also hope that one day medical training will do a much better job of preparing doctors to become their patient’s best advocates, actively learning and searching for cures rather than treating symptoms in ways that cause even more disease to develop. The system is failing so many of us.
If you decide to follow the diet, you’ll want to have an individualized meal plan, stresses Dr. Gonzalez-Campos. “The best possible clinical outcome is for each individual to meet her nutritional needs from well-balanced meals,” he says. “Ideally, we should all have the benefit of medical nutrition therapy and we should all avoid extremes in nutrient restrictions.”
Hi, I’m Bhuboy. Nutrition became my biggest passion after getting my blood chemical result showing my LDL cholesterol level over 481. I wanted to create a site where I could help you, my readers live a healthy and nutritious life. I believe we control our destiny, and we can choose to live a long and healthy life by eating right and treating our bodies with respect.
Hi, I think Keto is a great starting point. I am almost 60 years old and finally feel good, no fogginess or sluggishness. For the first time I have no hippy handles and my tummy is flatter – no bloating or puffiness and I feel more energetic. I have only been doing Keto for about 4 weeks. I am so happy with the results!! I will continue for another 8 weeks or so then I will add more foods back in BUT moderation is key. I will slowly up my healthy carbs and find what is good for me. Happy days everyone!!! =)
“What many diabetics aren’t aware of, is that it is the fat that is the problem when it comes to type 2 diabetes. Nearly 100 years ago, healthy volunteers were split into two groups – half were fed a fat-rich diet, and the other half on a carb-rich diet. Within just two days, the fatty diet groups’ glucose intolerance skyrocketed to amounts twice as high as those fed a carbohydrate-rich diet (9).
"There is still some debate on the effects of saturated fats and what constitutes a healthy dose. There has been quite a bit of buzz around grass-fed cows producing cream, dairy, and butter. Ghee has been popular on the market as well, as a clarified form of butter," Ms. Zarabi says. "It's really the trans fats that I think people need to understand and the harmful effects on the heart and cholesterol."
Also, consider supplementing with the amino acid leucine, as it can be broken down directly into acetyl-CoA, making it one of the most important ketogenic amino acids in the body. While most other amino acids are converted into glucose, the acetyl-CoA formed from leucine can be used to make ketone bodies. It’s also present in keto friendly foods like eggs and cottage cheese.
As Mark Sisson puts it, doing a keto reset restores our “factory settings,” which is our flexibility to alternate between different types of fuels and stored fats for energy, depending on what’s available. This flexibility has allowed humans to thrive for millions of years because hunter-gatherers didn’t always have access to constant abundance and variety of foods that we have today.
Another organ that plays an essential role in blood sugar regulation is the liver. It stores excess glucose as glycogen, and when glucose levels are low, glycogen is broken down to provide glucose . This process is regulated by two hormones: insulin and glucagon. Insulin normally promotes glycogen synthesis and interferes with glucose release from the liver.
2 days from grains my stomach bloat was gone and I knew at that point everything this article and American diet was a lie. I’ve been on keto for over 16 months. Down 50lbs. In 6 months. I am ripped. Haven’t lost any muscle mass. I eat greens protein and healthy fat. I whole juice to get macros and yes I add watermelon or berries fo palatability purposes. I still eat carbs just healthy choices. I’ve become carb tolerant.. your liver will produce all glucose without ever eating 1 carb. This is biased and poor representation of keto lifestyle. When your starving and no carbs to choke keto will still thrive on either or fuel.
