What Is Speed Keto

Keto 101 Explained What is Keto? What is Intermittent Fasting? Keto for Beginners

Speed Keto is a means of achieving faster ketosis and was created by Harlan Kilstein, who is not a medical professional or nutrition pro, but a coach, said Cynthia Thurlow, NP, who specializes in nutrition and intermittent fasting.

The Speed Keto program is similar to the traditional keto diet in that it requires individuals to eat a high fat, low carb diet.

Similarly, it also focuses on putting the body in ketosis, a metabolic state when your body burns fat instead of glucose for energy. When your body is in ketosis, its basically a fat-burning machine, thus giving keto its reputation as a weight loss tool.

The difference with Speed Keto? You can only eat one meal a day. The meal should follow the traditional keto guidelines of high fat and low carb macronutrients.

Its main goal is to attempt to become fat-adapted faster than a more traditional ketogenic diet, Thurlow told Healthline.

Fasting can help speed the process of getting into ketosis, explained Tony Castillo, MS, RDN, LDN, nutrition consultant for RSP Nutrition.

It can typically take 2 to 4 days to enter ketosis if you have less than 50 grams of carbs per day, he continued, pointing out that several factors, from what you eat to age and activity level, can extend the amount of time it takes to enter ketosis.

Even though you may enter fat-burning ketosis more quickly on Speed Keto, seeing a lower number on the scale might be misleading.

Intermittent Fasting And Keto In Human Evolution

For nearly two million years our ancestors lived in a world teeming with large prey . 3

When a hunt was successful our ancestors feasted, and when the hunt failed, they fasted.;

Over eons of human evolution, our ancestors whose brains and bodies functioned the best in fasted states were also the best at hunting and gathering foodand ultimately at surviving and reproducing. This means the genes that shaped their metabolism have been passed along to us.;

We see evidence of our bodies adaptation to cycles of fasting and feasting in the way we:

  • easily store fat: Our fuel supply in-between successful hunts
  • easily go into ketosis: How we convert stored fat and the fat we eat, into fuel during times when carbohydrates and calories are scarce.
  • have reduced cognitive ability when not fasting, because our brains are hard-wired to function optimally during times of food scarcity.

Pros And Cons Of Practicing Both Diets Together

Like any diet, combination or independent, there comes pros and cons. These may not be the case for everyone. But, these are the positives and negatives that may occur for most participants.;

Does Intermittent Fasting Cause Ketosis

Intermittent Fasting Guide

Intermittent Fasting and the Keto Diet often get lumped into the same sentence as two protocols that are similar or the same. With the field of Nutrition’s shift to focusing on actual fat breakdown vs. just calorie restriction, these two protocols fit the bill and therefore are commonly combined. BUT just because they both have the same end goal of increased fat burning, it does not mean they are the same thing.

Ketosis is a natural state within the body that both Intermittent Fasting and the Keto Diet tap into for many of the fat burning and mental clarity benefits.

Today, I’m going to be breaking down exactly what ketosis is and how Intermittent Fasting can help you achieve this “fat burning” state. Buckle up, we’re about to get EXTRA nerdy with the science-y deets in this one

What Is A Ketogenic Diet

A ketogenic diet means eating high-fat, moderate-protein, and low-to-no carbohydrates.

When the levels of ketones in our blood get elevated, we enter the metabolic state called ketosisthe root of the term keto diet.

The calorie breakdown of a typical ketogenic diet looks like:

  • 70-80% of calories from fat
  • 15-30% calories from protein
  • 0-10% calories from carbohydrates

Most ketones pack more energy per unit than carbs. They can also fuel the vast majority of your cells. For the few other types of cells that need glucose, your body will synthesize it from protein. This is a natural process called gluconeogenesis.

Foods To Eat On The Keto Diet

The keto diet places a huge emphasis on healthy fats as the primary component of your diet. The simplest way to say it is high-fat, moderate protein, very low-carb. But those terms can be vague. So having a list of go-to foods that you know you can eat can be super helpful.From there, you can get creative, and even try making some keto treats with keto-approved sugar-free sweeteners. This isnt an exhaustive list of food choices, but its a great place to start to get the ball rolling, and you can use this list to give yourself guidelines to follow when creating recipes or ordering from a restaurant.

Why Would You Do Intermittent Fasting On The Keto Diet

Basically, intermittent fasting might add to keto’s fat-burning effects, says Kelly Roehl, R.D.N., an advanced level dietitian at Rush University Medical Center.

In fact, Roehl adds some people use intermittent fasting to jumpstart ketosis. Intermittent fasting may drive blood-sugar levels down, which can promote or enhance ketosis when someone’s no longer in itfrom, say, deviating from the diet, she says.

Keep in mind, though, as hard as it is to maintain the keto diet, it’s even harder to maintain intermittent fasting on the keto diet. Unless practicing both works for your lifestyle and is something you can stick to, its not going to be sustainable.

First What Exactly Is Keto

Keto is a high fat, low-carb diet often mistaken for a high protein diet because so many of its popular recipes include bacon and other types of animal products, but the focus really is on fat.

The goal of the keto diet is to eat meals that are 60 to 75 percent fat, 15 to 30 percent protein, and 5 to 10 percent carbohydrates. Doing so puts you into a state of ketosis, where you can burn ketones from fat instead of glucose from carbs, speeding up your metabolism and increasing the potential for weight loss . Between burning fat during ketosis, and losing water weight that you’d normally hold onto to store carbs for energy, you may drop quite a few pounds on keto.

Normal staples of a keto diet include healthy fats , meat, and dairy products. Foods that are off limits are any kind of pasta or bread, starchy veggies like potatoes, beans, and anything that contains sugar, including many cocktails.

There are some variations on the standard keto diet, and some of them include sneaking some carbs in. The cyclic keto diet involves eating keto five or six days out of the week, and then eating a small amount of carbs on the other day or two to replenish energy stores . There’s also the targeted keto diet, common in athletes as well, in which you basically carb load less than an hour before strenuous exercise for a burst of energythe object is that you’ll burn off the carbs before they’re stored as fat in the body.

The Possible Health Benefits Of A Keto Intermittent Fasting Diet

There isnt research on the health effects of doing keto and IF together, but its clear that ketone levels increase when the plans are combined. This may help accelerate weight loss, says Dr.;DAgostino. Still, everyone responds differently, so this may not be true across the board, he says.

Shemek has all of her clients use keto or the IF and;keto combo. My clients are typically all prediabetic and overweight. Once they see and feel what eating in this way does for them including regulating their blood sugar levels they are able to stay on an IF and;keto plan easily. The success of the combined approach reinforces their committment, she says.

One interesting way that low-carb IF diets are being studied outside of weight loss is for cognitive health. Richard Isaacson, MD, director of the Alzheimers Prevention Clinic at Weill Cornell Medicine and NewYorkPresbyterian in New York City, says that doing a low-carb, time-restricted IF may be beneficial for calming down insulin pathways and letting the brain benefit from cleaner burning fuel, which may offer benefits for people with Alzheimers disease.

Are They Safe Together

In short, yes, it is safe to do intermittent fasting and keto at the same time. The trick is to make sure you are getting enough nutrition and calories to maintain function while still entering ketosis.

In ketosis, the body is ramped up into fat-burning mode and is feasting on all of those extra stores that accumulate around the body.Keto eliminates unnecessary carbs from the diet, so its easier to get all of your required vitamins, nutrients, proteins, and healthy fats.

The trick is to focus your keto diet to only include the good stuff. So eat lots of lean proteins, red meat, and dark, leafy vegetables.

May Smooth Your Transition Into Ketosis

Keto is about switching your body from using carbohydrates for energy, to turning fat into ketones. The typical way to do this is by cutting carbs and increasing fat intake in your diet. For many people this transition can take some time and it comes with a number of unpleasant side effects known as keto flu.;

IF speeds up ketosis and smooths the transition. When you fast, your insulin levels drop, causing your body to use its stored carbs . Once these are depleted your body begins using fat for fuel. 12

Think of fasting as a way to jump start ketosis.

Improved Blood Sugar Control And Insulin Sensitivity

Keto 101 – What is Intermittent fasting? | Keto Basics

By giving your body an occasional break from calorie consumption, you can also help improve blood sugar levels and enhance the insulin sensitivity of your cells. One clinical trial found that intermittent fasting may even be a better strategy than maintaining the same calorie deficit with six meals per day.

When combined with the keto diet which also has been found to help with insulin resistance and type 2 diabetes the two dietary strategies may work synergistically for improving blood sugar control. However, more research is needed on the effects of using them in tandem.

The Keto Intermittent Fasting Connection

The ketogenic diet and intermittent fasting share many of the same health benefits because both methods can have the same result: a state of ketosis.

Ketosis has many physical and mental benefits, from weight and fat loss to improved stress levels, brain function, and longevity.

However, its important to keep in mind that if you take a milder approach to keto intermittent fasting for example, eating within an 8-hour window you probably wont enter ketosis .

Not everyone who tries intermittent fasting aims to enter ketosis. In fact, if someone who fasts also eats high-carb foods, theres a very good chance theyll never enter ketosis.

On the other hand, if ketosis is the goal, you can use keto intermittent fasting as a tool to get there and improve your overall health.

Anyone who has been on keto for more than two weeks and with the okay from their healthcare team would like to add IF may do so.

If you have chronic kidney disease, a history of eating disorders, are undergoing active cancer treatment, or are pregnant or breastfeeding, its unlikely youre a good candidate for this combined diet plan. Even the individual diets may not be recommended for these populations. Check with your healthcare team.
