When carbohydrates are used by the body as an energy source, the blood sugar levels become unstable. As the energy source is not consistent it is difficult for your brain to stay focused for long periods of time. On the other hand, when you are in ketosis and the brain uses ketones as a fuel source, which has a consistent fuel source and you can focus for longer periods of time. Hence, you also tend to feel more active and alert.
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.
The cost of the Mediterranean diet, like most aspects of the diet, depends on how you shape it. While some ingredients (olive oil, nuts, fish and fresh produce in particular) can be expensive, you can find ways to keep the tab reasonable – especially if you're replacing red meats and meals with plant-based home cooking, some research suggests. Your shopping choices matter, too. Can't spring for the $50 bottle of wine? Grab one for $15 instead. And snag whatever veggies are on sale that day, rather than the $3-a-piece artichokes.
Fairly recently, the diet was introduced as a weight-loss diet by an Italian professor of surgery, Dr. Gianfranco Cappello of Sapienza University in Rome. In his 2012 study, about 19,000 dieters received a high-fat liquid diet via a feeding tube inserted down the nose. The study showed an average weight loss of more than 20 pounds in participants, most of whom kept it off for at least a year. The researchers reported a few minor side effects, like fatigue.
So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume fewer calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect.
With virtually no food groups as off-limits, DASH offers much more flexibility than other popular diet plans. It can also aid in weight loss and weight maintenance, given its emphasis on overall health. With all its praiseworthy qualities, you’d think everyone would be following a DASH diet plan. But here’s the surprising truth—less than 2 percent of the population actually follows the DASH diet.
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?
The keto diet isn’t new, and it’s been around for nearly a century. It was originally developed to treat people with epilepsy. In the 1920s, researchers found that raised levels of ketones in the blood led to fewer epileptic seizures in patients. The keto diet is still used today to treat children with epilepsy who don’t respond well to anti-epileptic drugs.
Taub-Dix suggests slowing down and listening to your stomach, not your brain. “Believe it or not, your stomach is about the size of two of your fists. When you eat some bread and butter, a glass of wine, an appetizer, a main dish, and dessert and cappuccino—your mouth and mind will feel satisfied, but your stomach might have wanted to go home halfway through your meal!”
Due to the highly restrictive nature of the keto diet, it is not safe for certain populations, including pregnant or postpartum women, children or growing teenagers, or individuals with certain diseases. If you are considering this diet, it is important that you speak with your primary care physician first and work with a Registered Dietitian Nutritionist to make sure you are getting all of the essential nutrients your body needs to thrive.
Sleep enough – for most people at least seven hours per night on average – and keep stress under control. Sleep deprivation and stress hormones raise blood sugar levels, slowing ketosis and weight loss a bit. Plus they might make it harder to stick to a keto diet, and resist temptations. So while handling sleep and stress will not get you into ketosis on it’s own, it’s still worth thinking about.
