5 Most Common Low-carb Mistakes (and How To Avoid Them)

5 Most Common Low-carb Mistakes (and How To Avoid Them)

A few months ago, I read a book called The Art and Science of Low-Carbohydrate Living. The authors are two of the world's leading researchers on low-carb diets. Dr. Jeff S. Volek is a Registered Dietitian and Dr. Stephen D. Phinney is a medical doctor. These guys have performed many studies and have treated thousands of patients with a low-carb diet. According to them, there are many stumbling blocks that people tend to run into, which can lead to adverse effects and suboptimal results. To get into full-blown ketosis and reap all the metabolic benefits of low-carb, merely cutting back on the carbs isn't enough. If you haven't gotten the results you expected on a low-carb diet, then perhaps you were doing one of these 5 common mistakes. There is no clear definition of exactly what constitutes a "low carb diet." Some would call anything under 100-150 grams per day low-carb, which is definitely a lot less than the standard Western diet. A lot of people could get awesome results within this carbohydrate range, as long as they ate real, unprocessed foods. But if you want to get into ketosis, with plenty of ketoness flooding your bloodstream to supply your brain with an efficient source of energy, then this level of intake may be excessive. It could take some self experimentation to figure out your optimal range as this depends on a lot of things, but most people will need to go under 50 grams per day to get into full-blown ketosis. This doesn't leave you with many carb options except vegetables and small amounts of berries. If you want to get into ketosis and reap the full metabolic benefits of low-carb, going under 50 grams of carbs per day may be required. Protein is a very important macronutrient, which most people aren't getting enough of. It can improve satiety and incr Continue reading >>

How Many Carbohydrates Do You Need?

How Many Carbohydrates Do You Need?

A perennial question, argument and debate in the field of nutrition has to do with how many carbohydrates people should be eating. While the nutritional mainstream is still more or less advocating a large amount of daily carbohydrate (with fat being blamed for the health problems of the modern world), groups often considered at the ‘fringe’ of nutrition are adamant that carbohydrates are the source of all evil when it comes to health, obesity, etc. They advocate lowering carbohydrates and replacing them with dietary protein, fat or both. This is a topic that I discussed in some detail in Carbohydrates and Fat Controversies Part 1 and Carbohydrate and Fat Controversies Part 2 and I’d recommend readers take a look at those for a slightly different look at the issue than what is discussed here. Arguments over recommended carbohydrate intake have a long history and it doesn’t appear to be close to ending any time soon. Typical mainstream recommendations have carbohydrates contributing 50% or more of total calories while many low-carbohydrate advocates suggest far fewer (ranging from the 40% of the Zone diet to close to zero for ketogenic diets). This article looks at the topic in detail. And while I originally wrote it quite a while back (some of you have probably seen it before), it was nice going over it with fine toothed comb for an update. While the majority of it stands up well over time, I was able to make some slight changes to the values, along with removing some original stuff that wasn’t really relevant. Enjoy. Introduction It’s safe to say that most carbohydrate recommendations that you will see are put in terms of percentages, you should be eating 45% of your calories as carbs, or 65% or whatever number is being used. As I discussed in Diet Percentag Continue reading >>

Sort type 2 is the more common type where cells resist insulin. Cells fail to respond to insulin or the insulin amount is insufficient). This condition tends to occur as a consequence of obesity. The pancreas produces enough insulin but the cell surface receptors have lost much of their ability to recognize the insulin and don't respond. Dietary carbohydrate does not cause diabetes. Many people with this type of diabetes are obese. Obesity is clearly a factor in this type. As the incidence of obesity in the U.S. has risen in recent decades, the incidence of diabetes has followed. An obese person is 3x more likely to develop this disease than a nonobese individual Continue reading >>

Sort What do carbohydrates contain? Carbohydrates contain energy that plants captured through photosynthesis Photosynthesis makes use of chlorophyll to capture energy and sunlight In this process, water donates hydrogen and oxygen, and carbon dioxide donates carbon and oxygen Water and carbon dioxide combine to form the sugar glucose What does glucose do? Carbohydrates - Glucose. Glucose is by far the most common carbohydrate and classified as a monosaccharide, an aldose, a hexose, and is a reducing sugar Glucose produced by photosynthesis provides energy for the work of all parts of the plant Plants do not use all the energy stored in their sugars Some remains available for use by the animal or human that consumes the plant Carbohydrates are the first link in the food chain that supports all life on Earth -----Glucose is the most used monosaccharide in the body Purpose of Carbohydrates? Carbohydrates meet your body's energy needs: Feed your brain & nervous system Keep your digestive system fit Within calorie limits, help keep your body lean Together with fats & protein, digestible carbohydrates add bulk to foods Indigestible carbohydrates yield little or no energy but provide other benefits What is the CHO consumption in Canada today?

How Many Carbs Should I Eat To Prevent Ketosis?

How Many Carbs Should I Eat To Prevent Ketosis?

When you’re on a low-carb diet, your body kicks into action, breaking down fats into ketone bodies to use for energy. This increase in ketones -- called ketosis -- is a normal adaptation to cutting carbs. In fact, the switch to ketosis is why low-carb diets work. Even though you could eat enough carbs to prevent ketosis, it's important to clarify why you want to avoid it. There's nothing unhealthy about ketosis, so you may just need to correct any misinformation to make the best decision for your weight-loss goals. Video of the Day Deal With Concerns Over Ketosis Ketosis is often confused with ketoacidosis, which is unfortunate -- ketosis is normal, while ketoacidosis is a dangerous condition related to type 1 diabetes. Most people on a low-carb diet tolerate ketosis without any problems. Then after the pounds are dropped, carb intake is gradually increased so you're out of ketosis by the time you reach the maintenance phase. If you decide to stay in an induction phase longer than the low-carb plan recommends, consult your doctor to be safe. People with type 1 diabetes are at risk for developing ketoacidosis from lack of insulin. Due to the complex metabolism of diabetes, they end up with high levels of blood glucose and ketones, which upsets the body's normal acid-base balance. When that happens, ketosis becomes ketoacidosis, causing symptoms like thirst, frequent urination, dry mouth, nausea, belly pain, rapid breathing and fruity-smelling breath. If you have symptoms, contact your doctor immediately -- diabetic ketoacidosis is a medical emergency. You may be wary about ketosis because you've heard about "ketosis flu." It's not really flu, but in the first few days or weeks of a low-carb diet, some people experience headaches, dizziness, fatigue, constipation or wea Continue reading >>
