Many people count net carbohydrates by subtracting fiber from total carbohydrates, but there are differences of opinion regarding whether fiber should be counted. I'm a registered dietitian who eats a diet containing less than 50 grams of total carbs daily and recommends carbohydrate restriction for people who want to lose weight, control diabetes, improve symptoms of PCOS (polycystic ovary syndrome), or experience better overall health. Very-low-carbohydrate ketogenic diets are well-known for their effectiveness at achieving weight loss.
In addition to formal research, there is an impressive amount of anecdotal evidence supporting carb restriction for weight loss and maintenance. Carbohydrate is the nutrient with the largest impact on blood sugar; for those with diabetes, consuming even modest amounts can raise blood sugar to levels that damage blood vessels and nerves. Although in some circles low-carb diets have a reputation for inducing muscle loss, research has demonstrated the opposite: A very-low-carbohydrate ketogenic diet promotes better retention of muscle mass during weight loss and overall improvement in body composition. People who restrict carbohydrates and increase intake of healthy fats like olive oil, coconut oil, butter, lard, tallow, avocado, olives, and nuts almost universally experience a drop in triglycerides and an increase in healthy HDL cholesterol. This is one of the biggest criticisms of low-carbohydrate diets, and there's some validity to it. Although people respond to carbohydrate restriction differently, generally speaking, tolerance for carbohydrates usually goes down after becoming keto-adapted. In my opinion, the benefits of keeping your carbs very low outweigh the drawbacks, but whether to follow a VLCKD is a matter of personal choice. Franziska Spritzler, a registered dietitian and certified diabetes educator, is a strong proponent of carbohydrate restriction for people struggling with diabetes, insulin resistance, obesity, and PCOS. Although VLCKDs are safe and healthy for most people, it's important to speak with your doctor prior to adopting a low-carb diet or making other dietary changes. KetoDiet note: When I first started following a low-carb ketogenic diet, I tried to keep below 20 grams of net carbs a day. Please note that due to the high volume it can take us several days before we can approve and reply to your comment. Thank you for this extremely important and clear explanation of the high fat low carbs diet. Hi Marta, I believe Franziska was referring to 150 grams of carbohydrates as macronutrients (not pasta, etc) Also, my understanding is that that test is not recommended for type 2 diabetics but only healthy individuals who want to test their carb tolerance. Oh I know, it can be quite frustrating and you sometimes have to look for a long time until you find a lowcarb-friendly doctor.
Before you begin your diet plan, it is better to research online and make some notes on the food that have low carbohydrates. Most people who eat a standard American diet are what I like to call sugar-burners not fat-burners.
William Banting, a British undertaker, deserves credit for developing the first VLCKD for weight loss in the mid 1800s. However, the degree to which carbohydrates need to be restricted to induce ketosis varies from person to person.
Soluble fiber may be absorbed and therefore could affect ketosis and blood glucose levels, while insoluble fiber simply passes through the GI tract unabsorbed.
The exact mechanism for how this occurs is debated among the experts, but it appears to be a result of several factors, including increased satiety, lower insulin levels, and increased lipolysis, or fat breakdown. For example, the Active Low-Carber Forums website has over 98,000 members, many of whom have lost 50 pounds or more and kept the weight off for several years by adopting a VLCKD. Elevated blood sugar also places a heavy burden on the beta cells of the pancreas to produce high amounts of insulin in an attempt to shuttle the sugar into the body's cells. In addition, VLCKDs promote large, fluffy LDL particles (Pattern A) which are relatively benign with respect to heart disease risk, particularly when compared to the atherogenic small, dense type characteristic of Pattern B. But in the interest of fairness, let's look at potential disadvantages of following a VLCKD. On a VLCKD, there are several off-limits foods that may include some of your favorites: pasta, rice, bread, most fruit, and sweets. In other words, your blood sugar will rise higher after consuming a high-carb item than it would if you followed a regular diet comprised of at least 150 grams of carbohydrate daily.
Fortunately, it's often temporary and can be remedied by drinking enough fluid, getting sufficient magnesium, and consuming additional salt – at least 1-3 extra grams per day.
If you love high-carb foods and find that avoiding them inevitably leads to feelings of deprivation which results in bingeing, then a carb-restricted diet probably isn't your best choice.
She follows a very-low-carbohydrate, ketogenic diet for blood sugar control and has experienced many improvements in her health as a result of making this change. For high-fibre diets, this can add up to 50 grams or more of total carbohydrates as defined by Phinney and Volek. I am 49 and have had PCOS since I was in my 20s (probably earlier) and was never advised to eat low carb. I manage a large migraine group on FB after having figured out the cause of migraine a few years ago.
However, unless there is a medical reason for anyone to stop following a low-carb approach (such as type one diabetes in some cases), there is no need to add extra carbs as long as the diet is rich in nutrients. It could be quite frustrating to explain to my doc that I'm doing well on a low-carb diet. I can't believe VCL is not prescribed to all patients with diabetes, PCOS, high cholesterol, etc. A low-carb ketogenic diet can be very helpful not only for weight loss but for blood sugar regulation and consistent energy because fat is a very stable source of fuel. As with any dietary approach, there are advantages and disadvantages to limiting carbs to very low levels. In fact, in every study – including the “gold standard” for evidence, randomized controlled trials – VLCKDs perform at least as well and generally better than low-fat diets for this purpose. Following a VLCKD is the most effective strategy to reduce postmeal blood sugar response – as well as the safest, given that insulin and all oral diabetes medications carry some risks.
LDL cholesterol response to carbohydrate restriction is variable; it's believed that roughly 50% of people experience a rise while the other half either see a decrease or experience no change.
Although there are acceptable substitutes for many of these items, even the most enthusiastic low-carber will admit that there are some foods that simply can't be successfully replaced by a low-carb version, such as bread or baked potatoes.
This is sometimes referred to as physiological insulin resistance in order to distinguish it from the pathological insulin resistance that occurs in Type 2 diabetes, obesity, and metabolic syndrome.
Franziska works in private practice using a low-carbohydrate, whole-foods approach with her Southern California clients and provides nutrition coaching via Skype, phone, or email for clients living in other parts of the US. One of the most important issues migraineurs face is the carbohydrates electrolyte disruptive effects. In any case, your health is more important and he will realise it once he sees it improving! My endocrinologist has approved my diet because he actually follows the recent research and has seen the benefits of LCHF.
I don't do very low-carb like below 20-30 grams of net carbs but I still stay in ketosis on most days even at higher levels of net carbs (maintaining my weight). Franziska is a certified dietitian and has personal experience with very low-carb ketogenic diets!
Atkins popularized it again in the early 1970s after reviewing decades-old nutrition research in his attempt to discover a plan that would allow people to lose weight without going hungry – his own Achilles' heel when it came to sticking to a diet.
Because of this, you're instructed to eat at least 150 grams of carbohydrate for three days prior to taking an oral glucose tolerance test (OGTT), which allows you to regain carb tolerance.
She is also a freelance writer whose articles have been published online and in diabetes journals and magazines.
It was only a few months later when I learnt that in certain health conditions such as Hashimoto’s (an autoimmune disease causing low thyroid function), following a VLC may not be the best option. Glucose takes water out of the cells and pushes sodium out as well, causing edema and lack of voltage for the brain (I enjoyed your increased salt comment!
It kinda worries me to be honest, but I'd be really thankfuk if you made that clear for me please because health comes first Thank you. If I feel like I need to lose a few pounds (like it was after Christmas), I just avoid dairy and anything sweet-tasting and stay at about 30 grams net carbs. Over the years, the very-low-carbohydrate ketogenic diet has been criticized for being too restrictive, difficult to maintain long term, and unhealthy. Eric Westman of Duke University has conducted studies in which people were able to reduce or significantly decrease diabetes treatment by following a diet containing less than 20 grams of total carbohydrate per day(in this study and also here).
Initially I lost about 20lbs in the first 6 months but then I have been gaining & losing the same 5-10 lbs since.
Maybe you can try a low-carb, moderate protein, high-fat diet, of course, after consulting it with a specialist. If only they were willing to do the research and stop judging the atkins diet based on pseudo science funded by the food and pharmaceutical industries. However, many people find that this way of eating is the only one that allows them to lose weight and effectively control diabetes.
Jeff Volek recommend 50 or fewer grams of total carbohydrates per day on a LCKD and do not mention fiber or net carbs in this regard. I really enjoyed your explanation and will share your expertise with my group by sharing this article. I suppose a happy medium is possible to retain a neutral pH body acidity level to remain healthy.
