The brain is composed of a network of neurons that transmit signals by propagating nerve impulses. The propagation of this impulse from one neuron to another is typically controlled by neurotransmitters, though there are also electrical pathways between some neurons. Neurotransmitters can inhibit impulse firing (primarily done by γ-aminobutyric acid, or GABA) or they can excite the neuron into firing (primarily done by glutamate). A neuron that releases inhibitory neurotransmitters from its terminals is called an inhibitory neuron, while one that releases excitatory neurotransmitters is an excitatory neuron. When the normal balance between inhibition and excitation is significantly disrupted in all or part of the brain, a seizure can occur. The GABA system is an important target for anticonvulsant drugs, since seizures may be discouraged by increasing GABA synthesis, decreasing its breakdown, or enhancing its effect on neurons.
Long-term use of the ketogenic diet in children increases the risk of slowed or stunted growth, bone fractures and kidney stones. The diet reduces levels of insulin-like growth factor 1, which is important for childhood growth. Like many anticonvulsant drugs, the ketogenic diet has an adverse effect on bone health. Many factors may be involved such as acidosis and suppressed growth hormone. About 1 in 20 children on the ketogenic diet will develop kidney stones (compared with one in several thousand for the general population). A class of anticonvulsants known as carbonic anhydrase inhibitors (topiramate, zonisamide) are known to increase the risk of kidney stones, but the combination of these anticonvulsants and the ketogenic diet does not appear to elevate the risk above that of the diet alone. The stones are treatable and do not justify discontinuation of the diet. Johns Hopkins Hospital now gives oral potassium citrate supplements to all ketogenic diet patients, resulting in a sevenfold decrease in the incidence of kidney stones. However, this empiric usage has not been tested in a prospective controlled trial. Kidney stone formation (nephrolithiasis) is associated with the diet for four reasons:
The good news here is no! All the evidence points to the fact that a low carbohydrate diet actually does lower blood glucose and A1c levels and does contribute to weight loss. The problem is we do not yet have enough large studies, over enough sustained years to support evidence that people with diabetes can remain on a highly restrictive Ketogenic Diet for the rest of their life and also not have other consequences to their health.
Hi Maya. I LOVE your site!! Interesting, informative with fab recipes and ideas. Hubby and I have just started eating low carb and I have to say, we are not finding it too difficult and I already feel sooo much better!! I find the hardest part is choosing low carb veg, I feel as if we are not eating enough. Any suggestions on how to get more veggies into our diet?
In January 2017, at 63 years of age, I was diagnosed with type 2 diabetes. I had probably been living with it unknowingly for years. In 2009 my doctor recommended the South Beach diet because I was showing blood-sugar levels that were considered pre-diabetic. I stayed on it for a while but then, as with all other diets I’ve tried in my life, I failed and put all the weight back on, plus some. When I was officially diagnosed last year with type 2 diabetes I was a whopping 284 pounds (129 kg). I was always fatigued, could barely walk a block without getting tired and my health was failing.
How would you like to take all the great weight-loss results you’ve just read about—and double them? That’s what happens when you supplement your diet with a combination of vitamin D and calcium, according to a Nutrition Journal study. Just four weeks into the 12-week experiment, subjects who had taken these two nutrients—found in abundance in some yogurts—lost two times more fat than the other group! To get similar results at home, start your day with one of these Best Brand-Name Yogurts for Weight Loss.
Recently, I had the chance to speak with the author of “The Mediterranean Diet Plan,” Susan Zogheib, a registered dietician about her diet plan. Susan will be joining me for an upcoming episode of HeartTalk presented by Capital Cardiology Associates this month (Sunday, June 24th). I wanted to share the highlights of conversation before YOU grocery shop this week so that you can discover the join of healthy eating this summer.
Ketoacidosis (KA) is a life-threatening condition in which your body doesn’t make enough insulin. This causes you to have dangerously high levels of ketones (substances occurring when the body uses fat stores for energy) and blood sugar. The combination of both makes your blood incredibly acidic, and this can, in turn, change the normal functioning of your internal organs such as your liver and kidneys. Patients suffering from ketoacidosis must get treatment immediately or they could slip into a coma and even die.
For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.
In the study, researchers fed mice (!) a keto diet for three days (!), and then ran a glucose tolerance test. They noticed that while the mice on a keto diet had a lower fasting blood glucose, it got higher after the glucose tolerance test and there were signs of a reduced effect of insulin compared to mice on regular mouse chow. That’s basically it.
Of the 28 participants enrolled in the study, 21 completed the 16 weeks of follow-up. Reasons for discontinuing the study included unable to adhere to study meetings and unable to adhere to the diet; no participant reported discontinuing as a result of adverse effects associated with the intervention. All but one of the 21 participants were men; 62% (n = 13) were Caucasian, 38% (n = 8) were African-American (Table (Table1).1). The mean age was 56.0 ± 7.9 years.
Diabetes is one of the most common chronic diseases in the world. In 2014, diabetes affected about 387 million people worldwide and resulted in $612 billion dollars of health-related costs.  Unfortunately, as a conventional western lifestyle of poor nutrition and exercise habits becomes more popular, diabetes is expected to affect about 592 million people worldwide.  In the United States alone, diabetes increased from 5.58 diagnosed cases in 1980 to 22.3 million diagnose cases in 2013. 
I am sorry you had this experience. I feel that this educator was not giving you good advice. All my women who want to lose weight are recommended to consume 30 grams of good carbohydrates at each meal, and 15 at each snack. If you were not trying to lose weight, I would have recommended 45. I find this is all it usually takes to begin to lose some weight as you start to get active. Patients set their own goals with motivational help from their Certified Diabetes Educator. Our intent is never to insult, and you should not have gone through that. It sounds that you have now found the right path. There are many CDEs who could help you, so see what tools and motivation others may offer. I wouldn’t let one bad apple spoil the whole bunch. Many CDEs are also diabetic.
The low-carb diet induces ''nutritional ketosis," Dr. Saslow tells EndocrineWeb, which is not the same as ketoacidosis. Ketones are a chemical your body produces when you burn stored fat; if you are on a low-carb diet you may be ''in ketosis.'' Ketoacidosis is different; it is a life-threatening condition in which levels of ketones and blood sugar are dangerously high, which may occur in people who have poorly controlled diabetes.
Below is a quick graphic of a meal plan on the traditional Mediterranean diet, it is the same meal plan that I also follow. Under the graphic you can find details, tips and links to the recipes. I provide a variety of choices for meals that you can mix and match with links to the recipes. For more ideas just head over to the Recipe Index and you will find a large selection of Mediterranean recipes.
Several comprehensive studies and meta-analyses have demonstrated that after a few months or even a year of a low carb diet versus a moderate/high carb diet, there are no significant differences in the amount of weight lost (2,3,4,5). I will say, however, most of these diets are NOT keto and are simply lower carb (i.e. 20%). Also, long-term effects (beyond 1 year) are not often studied due to budgetary constraints, so interpret results as you wish.
If it all feels a little bit 90s, that’ll be because this was basically the diet that kept Rachel from Friends looking, well, like Rachel from Friends. Think of it as the 20th-century version of no carbs before Marbs. Thankfully though, the old premise of each as much as you want, as long as you don’t go near a carb, has had a makeover. The New Atkins diet reintroduces carbs in phases.
Readers will enjoy a diet rich in fruits, vegetables, low-fat and nonfat dairy, lean meats/fish/poultry, nuts/beans/seeds, heart healthy fats, and limited amounts of whole grains. Banished are the empty calories from refined grains and added-sugars. The result: improved metabolism, lower body fat, improved strength and cardiovascular fitness--with the diet plan proven to lower cholesterol and blood pressure without medication, and without counting calories!
The classic ketogenic diet is not a balanced diet and only contains tiny portions of fresh fruit and vegetables, fortified cereals and calcium-rich foods. In particular, the B vitamins, calcium and vitamin D must be artificially supplemented. This is achieved by taking two sugar-free supplements designed for the patient's age: a multivitamin with minerals and calcium with vitamin D. A typical day of food for a child on a 4:1 ratio, 1,500 kcal (6,300 kJ) ketogenic diet comprises:
Twenty-one of the 28 participants who were enrolled completed the study. Twenty participants were men; 13 were White, 8 were African-American. The mean [± SD] age was 56.0 ± 7.9 years and BMI was 42.2 ± 5.8 kg/m2. Hemoglobin A1c decreased by 16% from 7.5 ± 1.4% to 6.3 ± 1.0% (p < 0.001) from baseline to week 16. Diabetes medications were discontinued in 7 participants, reduced in 10 participants, and unchanged in 4 participants. The mean body weight decreased by 6.6% from 131.4 ± 18.3 kg to 122.7 ± 18.9 kg (p < 0.001). In linear regression analyses, weight change at 16 weeks did not predict change in hemoglobin A1c. Fasting serum triglyceride decreased 42% from 2.69 ± 2.87 mmol/L to 1.57 ± 1.38 mmol/L (p = 0.001) while other serum lipid measurements did not change significantly.
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.
