Cyclical Ketogenic Diet

I’ve written about the standard ketogenic diet (SKD) before and a modified version, the targeted ketogenic diet (TKD). The cyclical ketogenic diet, like the TKD is another variant of the keto diet, with an emphasis on athletic performance.

Cyclical keto (CKD) is similar to the TKD in that carbs are used to enhance performance and maximize hypertrophy. The CKD however, uses “carb ups” or “carb loading” as opposed to targeted ingestion of carbs around workouts. A “carb up” or “carb load” is a dramatic increase in the amount of carbs you’re eating 1 to 2 days per week. The amount of carbs depends on the person and your non-carb up amount of carbs. Generally, 50 to 70 percent of your daily calories will be carbs on your carb up/load days. As with most things, a strict schedule or plan is essential for best results. This is especially true when optimizing nutrition for performance. The CKD is difficult to implement without a somewhat strict workout schedule.

To implement a CKD, you would begin to carb load about 5 hours before your last workout of the week. Anywhere from 20-50 grams of carbs can be eaten in this window. An hour or two before the workout consume another 25-50 grams of carbs ideally from glucose and fructose, as fructose will replenish liver glycogen. If you are very active and perform very high intensity exercise, you may benefit from 2 carb up days. If this is the case, during the first day calories should be about 70 percent from carbs (15 protein and 15 fat), preferably high glycemic index. The second day reduce to about 50 to 60 percent of the days calories from carbs (25 protein and 15 fat) and switch to low glycemic index sources.

The time it takes to get back into ketosis (a fat burning state) will vary by person, body composition, and how long you’ve been on a keto diet. There are some tricks to speed up the process though. The first day after a carb up, get back to a SKD, with fewer carbs than normal (0 to 2 percent). Also, implement a time-restricted eating schedule; basically don’t eat after sundown. The second day it’s best to do fasted HIIT or even a fasted high intensity weight training session, first thing in the morning. On the third day upon waking, while fasted, do some medium intensity cardio or weight training. Not too light, but less intensity than the previous day. Carbs should stay be the 3-5 percent range. After these few days, fat burning should be re-established and liver glycogen should be depleted.

Keep in mind, the CKD is not for the average person. Or even an active person. If you’re active, even daily you can make great improvements with your fitness, strength, and even muscle growth with a SKD or a TKD. The CKD is for optimizing muscle growth and performing daily, very high intensity workouts. Like any method that allows for muscle gain, fat gain though slight, will occur.

The Thyroid Post

The thyroid is a butterfly shaped endocrine gland located in your neck. It’s an endocrine gland, meaning the hormones it creates/regulates are secreted directly into the bloodstream instead of passing through a duct. The hormones that are most involved with the thyroid are thyrotropin, thyroid stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4). Because the thyroid is an endocrine gland, it is very vascularized; it contains a lot of blood vessels.

Through the secretion and regulation of the hormones mentioned above, the thyroid gland has an impact on: metabolism, the central nervous system, body temperature, muscle strength, menstrual cycle, cholesterol levels, and weight. With so many important bodily processes affected by the thyroid, it is no surprise that thyroid disruption is a very serious issue for so many people.

Graves’ Disease

Thyroid disruption is most commonly diagnosed as Graves’ disease, Hashimoto’s disease, and/or hypothyroidism. There is some overlap between the three, but they are different. Graves’ disease is the most common, and consists of an excess of thyrotropin, which leads to the capillaries becoming too dense. When thyrotropin levels get too high, vascular endothelial growth factor A (VEGF-A) is produced, which is what leads to capillaries getting too dense, which is Graves’ disease.

Hypothyroidism/Hashimoto’s

Hypothyroidism is when thyroid hormones levels are too low. While hypothyroidism and Hashimoto’s disease are often thought to be the same, Hashimoto’s is the disease that causes the symptom of hypothyroidism. Hashimoto’s disease is an autoimmune disease, in which the immune system attacks thyroid tissue as if it were a virus. Some symptoms of Hashimoto’s disease include: goiters, fatigue, weight gain, depression, constipation, and more.

Causes

 

Knowing that Hashimoto’s disease is an autoimmune disease is a big advantage in treating the symptoms and addressing the disease itself. Hashimoto’s, like all autoimmune diseases are at their root, cause by inflammation. Chronic and systemic inflammation that causes the body to attack certain tissues, leading to disease states. In the case of Hashimoto’s, as with the majority of autoimmune diseases, managing and reducing inflammation is the key to recovery.

Inflammation

 

A very common source of inflammation is diet, more specifically gluten. In regards to thyroid disruption and Hashimoto’s disease, the fact that the protein structure of gluten very closely resembles thyroid tissue is no coincidence. There is also a strong association between Celiac disease (intolerance to gluten), non-celiac gluten sensitivity, and Hashimoto’s disease. Gluten can be a very inflammatory substance and can lead to many different health problems. Along with gluten, people are often found to have food intolerances for dairy. A caveat to this is that when people remove both gluten and dairy from their diet, then reintroduce dairy, there is, in many cases, no problem. But everyone is different, so you would have to see what works best for you. Another cause of inflammation is frequent surges in insulin levels, which again, can be attributed to a diet consisting of gluten, refined carbohydrates, and sugar.

Gluten/Inflammation/Autoimmune disease

 

How gluten ties into inflammation and an autoimmune response seems complicated, but really isn’t. When gluten, as an inflammatory substance, is ingested the small intestine becomes inflamed. Over time, this inflammation leads to small tears in the intestinal lining, which allows gut bacteria to leak out of the gut. This is known as leaky gut, a very disruptive issue on its own. If this leaking occurs for long enough, the body will begin to identify certain tissues as foreign and the immune system will attack them. If the main cause of the inflammation is gluten, the body will see that structure as a virus, which is a problem because thyroid tissue very closely resembles the structure of gluten protein. So, in a mistaken attempt to try to rid itself of a “virus,” the body attacks its own tissues, which is the case with Hashimoto’s, leaky gut, and many other autoimmune disease.

Fix Me!

 

It’s not all bad news. Hashimoto’s disease, while serious and very disruptive can be addressed very easily. While there are successful medications, such as levothyroxine, the best method is usually to address the cause instead of simply reducing the symptoms. Let’s start with promoting a healthy thyroid. The thyroid gland relies on several key vitamins and nutrients to function optimally.

  • Iodine (essential for thyroid hormone production)
  • Selenium (essential for thyroid hormone production)
  • zinc
  • tyrosine
  • magnesium
  • vitamins B12, B2, and C

Foods that can provide these are:

  • seafood
  • eggs
  • potatoes
  • shellfish
  • certain nuts
  • Beef and chicken
  • certain legumes (beans)
  • lots of different vegetables (I always recommend dark, leafy veggies)

Some other good foods to eat are probiotic containing foods, such as yogurt, collagen, and fermented foods like kimchi.

What should you avoid? The answer to this seems to be not very cut and dry. Some things are obvious though.

Avoid eating:

  • gluten (grains, pasta, bread, etc.),
  • sugars,
  • overly processed foods,
  • soy (everyone should really avoid soy),
  • vegetable oils, canola oil (omega-6 fatty acids increase inflammation, which is an essential bodily process, but in this instance our goal is to reduce inflammation.)

Cruciferous vegetables (broccoli, cabbage, cauliflower, etc.) are usually put on the “Do not eat” list, but this seems to be based on research from the 50’s mistakenly stating that they were goitrogenic. There’s a very secret technique to make these veggies safe to eat..Steam them! I would hope you’re not munching on raw broccoli either way though.

Another gray area is dairy. Some people can have cheese and be fine others cannot. The milk protein, casein, seems to be the factor in this instance. So, if you want some butter (who doesn’t..) you will most likely be ok with ghee or clarified butter, which has the milk protein removed.

Digestion playing a big role here, stomach acid (HCL) is very important. Most people have low levels of HCL which is needed for proper digestion and nutrient/vitamin absorption. To naturally increase your levels of HCL try eating more:

Diets

 

To simplify all this: You need to change your diet. Maybe drastically, maybe not. The first priority is removal, completely, of gluten. The secondary goal should be to manage and reduce inflammation totally. The diets that are best at this are:

  • Ketogenic
  • Paleo
  • Gluten-free
  • Vegan/Vegetarian

Each of these will provide relief from most of the symptoms of Hashimoto’s disease and/or hypothyroidism. The ketogenic diet is a very anti-inflammatory diet, as its staple is very low carbs from starch and high fat. When the body is metabolizing fat instead of glucose, less inflammation is produced and there is less of an insulin response.

There is also some relatively recent research demonstrating that intermittent fasting, IF can help with symptoms of Hashimoto’s as well. IF helps with appetite control, insulin sensitivity, and can significantly lower C-reactive protein (CRP) which is a main cause of inflammation. Just make sure if using IF to eat enough calories; severe calorie restriction is never a good thing.

TL;DR

 

Don’t eat gluten. Eat a diet of whole foods. Eat your meat and veggies. Avoid refined carbs and processed foods.

Keto Pizza

Every once in a while you just crave some pizza. This satisfied that craving. It was delicious, satisfying, and pretty easy to make. Very low carb and a bunch of fat. Also bacon.

Dough recipe from Carolyn Ketchum’s Everyday Ketogenic Kitchen. The Keto Cinnamon Rolls I posted used a similar dough, but sweet instead of savory. I loaded my half of the pizza with bacon, ricotta, and jalapeños.

 

How Keto Is It?

Whether you’re new to the ketogenic way of eating, or you’ve been fat adapted for a while, you will come across new meals or foods you haven’t had before. If you want to know for sure ‘how keto’ a food or meal is, thus little tool can be very useful. As long as you have the nutritional information to enter in, this calculator will grade the food or meal on how keto-friendly it is.  It’s even color coordinated.

The tool can be found here:  Keto Meal Calculator

It’s a downloadable Excel (or equivalent) file. Credit for this useful calculator goes to FB group, Common Sense Keto.
